Authors: Muncinelli Gianfranco  , Pinheiro De Lima Edson  , Gouvea Da Costa Sergio E.  , Deschamps Fernando
Published: February 2025

The success parameters for any projects are jeopardized by risk factors. The main barriers to effective risk management are related to the process by itself (identifying, analyzing, responding and monitoring), and with the parameters related to project risk. This paper intends to determine factors for identifying and analyzing risks in project management in automaker digital manufacturing projects. The main objective of the research is to provide a study of risk identification and classification with a list of authors that studied that subject, where the project manager can efficiently use during the project planning, regarding the next step of project risk management. The research design is desktop study, based on the process of a critical literature review with a focus on information systems and business research papers, books, case study from a manufacturer and theoretical articles, etc. Data analysis use the mechanism of triangulation for producing an assessment exercise of the digital manufacturing practices adopted by the company. The manufacturing engineering team could insert the new model into their day by day work reaching opportunities and mitigating threats/risks. The findings bring the risk structure (risk ontology) where the risks are classified in the following aspects: technical risks, people risks, organizational risks and vendors risks. Risks need to be managed from the beginning by identifying them, assessing their likelihood and possible impact, and preparing an overall action plan to deal with them.

Authors: Skarka Wojciech  , Pabian Tomasz  , Wąsik Mateusz
Published: February 2025

Nowadays, engineers and designer are forced to conduct their work quickly and efficiently. That led to introduction and development of many computer-based tools, which aid the process of designing. One of those methods is a topology optimization, which can be used in many branches of industry, such as an automotive or aerospace industry, where many shells and monocoque structures are used, for which this method is very useful. It is an iteration approach that allows obtaining optimal results of material's placement and continuity in a construction, as well as its properties and thickness, in accordance with introduced loads, boundary conditions and needed shape. That allows the designer to obtain needed stiffness and strength of the design, with minimum weight and usage of resources. There are many ways to conduct the topology optimization and one the simplest is considering the material as isotropic and homogenous, which greatly simplifies the calculations and reduces needed time. Nevertheless, the composite structure, especially laminates, should be considered as orthotropic and heterogeneous. The process of topology optimization is shown in the case of preparing the concept solution for lightweight, shell-based support system for an electrical UrbanConcept class vehicle for Shell Eco-Marathon. The description of the outer shape, loads acting on the structure and boundary conditions connected with other subsystems were described, as well as the preparation of the computer model and the process of topology optimization using Altair HyperWorks software. Additionally, the results were presented and a final solution obtained basing on them.

In the past few years, Additive Layer Manufacturing (ALM) utilisation has increased significantly. The high cost of manufactured products is the main barrier for the implementation of this technology in mass production. This implies that companies need to search the cost-efficient way to remain competitive. The aim of this study is to develop a cost model and software tool while addressing the issues and challenges confronted in the previous developed AM cost models. It focuses on two processes viz. Selective Laser Sintering (SLS) and Electron Beam Melting (EBM). Despite the current high initial investment, a growth of these technologies in various sectors such as aerospace, automotive, medical and electronics has driven a decrease of the machine purchase price. In addition, this growth has reduced the manufacturing cost, owing to the learning curve effect. A high-level cost model has been developed to combine cost information of SLS and EBM processes for metals. The software tool analyse the data through cost model and gives trends and current distribution of the main cost drivers; both the machine cost and material cost decreased slightly, however, post-processing cost increased significantly and became the second highest cost. This study enhances the ALM development in industries giving a new insight and details of the current state of this new technology. Moreover, it will benefit the industries in ALM market knowledge in terms of manufacturing costs.

Published: February 2025

With the advancing digital transformation, verification and validation with simulations is getting more and more important. Reduced hardware testing and shortening of development times require a significant boost in digital vehicle development. The Functional Mock-up Interface (FMI) is a tool independent standard to support both, model exchange and co-simulation of behavior models using a combination of xml-files and compiled C-code. In this paper the increasing importance of interllectual property protection within the scenario of cross-company collaboration is discussed. A recommended process to secure IP including a complete decision-making chain, from analyzing the simulation model and identifying the IP, classification of security level and usage, identification of the threads to the IP and eventually choosing of appropriate protection mechanisms is presented. Subsequently, an analysis of the current technical landscape for necessary IP protection measures reveals the need for action within the field of digital rights management/license management, and the use of state-of-the-art source code obfuscation as a technical measures.

Published: February 2025

Driving is a high-demanding task, related to human capacity, required performance and events occurring in the external environment. In this context, the driver's health status monitoring is expected to support safety system and reduce the number of traffic accidents. Among the drivers' conditions, drowsiness and distraction are thought as crucial risk factors that may result in severe injuries. The paper defines a transdisciplinary roadmap to monitor the driver's health status and to map the perceived user experience, based on three layers: the human conditions to detect, the vital parameters to be monitored, and the adopted technologies. The paper proposes a technological set-up focusing on the driver's drowsiness detection, in the context of smart city framework and innovation 4.0. Indeed, such technologies could be embedded in the future “smart car” and communicate with external services to control the driver's performance and improve the safety inside and outside the car. A preliminary technological set-up has been realized embedded into a Maserati car.

Published: February 2025

Large corporations work with legacy systems to standardize the execution of activities, support, data formatting and communication between different sites around the world. However, some companies in certain countries have been unable to integrate these systems due to a number of factors involving cultural aspects, local legislation and infrastructure. With the arrival of the Fourth Industrial Revolution, also known as Industry 4.0, there is a need to deploy digital projects that have a dependency relationship with legacy systems in acquiring and managing information making it more accessible to the user. In addition, this integration needs to be synchronized with other countries so as not to lead to uneven maturity among organizations, leading to difficulties in adopting I4.0 in different plants around the world. The objective of this article is to elaborate an evaluation methodology between legacy and local systems, using multi-criteria decision-making methods (MCDM/A), in order to verify if both attend the specifications of the organization's digital transformation projects. As a way to evaluate the proposed model was used the case of an automotive company located in Brazil for more than 20 years that has one of its units in South America (Colombia) with local systems that are bringing numerous difficulties of implementation of projects geared to I4.0. With the support of the MCDM/A methods, it was noticed that some local systems would be able to attend the scope of the projects since it would allow a flexibilization to customize certain points of integration.

Authors: Ricci Federico  , Pelosi Annalisa  , Panari Chiara  , Chiesi Andrea
Published: February 2025

Our aim was to evaluate the effect of training on safety knowledge, attitudes, behaviors and health outcomes. Employees of an occupational training institute (n=141), were randomly assigned to mandatory (G1) or discretionary (G2) safety training or to control group (G3). All outcomes were measured before training (T0), immediately after (T1) and then three (T2) and six months (T3, only for knowledge) later. The original training model (10 hours lasting 16 weeks) was divided into three steps: classroom presentation of everyday risk conditions, through original videos; individual on-the-job practice; classroom discussion of self-cases, in small groups. Training had an impact on safety outcomes (no difference between G1-G2), but its efficacy generally decreased at T2. We found greater effectiveness when training was delivered by qualified trainers andtraining contents were closely related to daily work experience. Constraints are due to ecological characteristics of empirical study and limited number of participants. Effects of training can be maintained only by providing re-training over time and highlighting usefulness of training instead of compulsory attendance. We provided a new methodological approach and valid measures in order to extend the investigation to other work sectors. Data highlight an effective training model and show that correct risk perception can determine safer behavior through the mediation of: a) positive attitudes toward safety; b) occupational safety climate.

Published: February 2025

There are several benefits reported in literature related to the adoption of lean in development environments, as rework reduction, innovation and an increase in value adding. However, there is a few literature regarding how to manage uncertainties, to integrate developers, to maximize the knowledge sharing and minimize its losses in a lean product development environment. The Toyota Kata approach enables the establishment of management routines that can conduct the development process, deal with uncertainties, stimulate organizational learning and integrate and align all development team towards the development goals. This paper aims to demonstrate how the Toyota Kata approach can be used in a Lean Product Development environment and to present the initial results of its application in the development of an innovative product, a magnetic refrigerator. Initially, a literature review was performed. Then, a model for Toyota Kata in Lean Product Development environments was developed. Finally, an action research was performed in the development of the product of a magnetic refrigerator. As a result, an increase in integration, value focus, alignment towards development goals and knowledge sharing was observed. The Toyota Kata approach provided a management routine that enabled daily management of lean product development. Also, it contributed to reduce the risks associated with product development.

Published: February 2025

Many manufacturing companies are suppliers that deliver unique solutions to different business customers. Intense quotation work, with a high demand on accuracy and quick response, and development projects executed in close collaboration with customers and other actors characterize these companies. The projects can run for years or a few weeks depending on the business. Changes of requirements are frequent and technology development required for improved functionality, sustainability and competitiveness. The use of a product platform has been acknowledged as a strategic enabler for product family development and mass customization. However, companies struggle with adopting the common platform approach building upon pre-defined modules and components as it constraints the fulfilment of unique customer requirements and the introduction of new technology at high pace. This work reports the results from case studies conducted in collaboration with four companies. They are in many ways different but face the same challenges when it comes to customization, fluctuating requirements and need of high pace in technology advancement. The focus of this paper is on their initial states; including how they work with their product concept before the customer entry point, the work that is initiated when an order is accepted, the character of requirements and the adoption of product platforms. Criteria on, and identification of, new platforms models, termed Design Assets, are presented followed by a mapping to the Design Platform concept pointing out areas upcoming work, both scientifically and at the companies.

Published: February 2025

As of 2008, the R&D Development Program of Brazilian Electricity Sector (Brazil, Law n° 9.991/2000) regulated by the Brazilian Electricity Regulatory Agency (ANEEL) started to contemplate the Product Development Process (PDP) in its innovation chain, a fact that not only stimulated the transfer of innovative technologies from the research of the electric sector to the industry, but generated the need for specialized knowledge to manage these projects. In view of this, MoR&D, acronym for “Integrated Product Development Model Oriented for R&D Projects of the Electric Sector”, aims to assist in the planning of projects to transform the results of the electric sector research into ready-to-market products. The MoR&D is the result of compilation of PDP models, theirs tools and concepts. It is composed of macro-phases, phases, stages and activities, correlated with the needs of the typical ANEEL projects. This paper presents a case study of the planning of a Head Production Series design for electronic equipment, illustrating the MoR&D application process. Their contribution can be concluded as a key step for effective participation of the industry in the process of generating solutions to problems that afflict the electric sector. The model is the result of a doctoral thesis sponsored by Companhia Paranaense de Energia (COPEL) in favor of best practices applied to the management process of its processes, which, now shared, may contribute to the various energy concessionaires in Brazil and in the world that excel for the quality of its services.

Authors: Lee Ching-Hung  , Chen Chun-Hsien  , Lee Yu-Chi  , Wang ZuoXu
Published: February 2025

Manufacturers begin to give more and more customizing offerings and services of their products in order to create the values that really fits customers' needs and wants rather than to supply materialized products directly. Systematic design approaches and modularized computer-aided design systems are the key to reduce the design complexity and would lead to successfully converge divergent thinking and creativity to the specifically defined problems. Therefore, this research aims to propose a creative design system framework with an integrated method of customizing product/service systems (PSSs) for the solution modularization. A systematic design model consists of three phases: 1) identify problems and initial design (IPID); 2) design trimming and resolution generation (DTRG); 3) interaction mapping and design evaluation (IMDE). In phase I, we can understand customer requirements through interviewing by knowledge elicitation methods and root cause analysis. In phase II, we can generate more possible service components related to a specific product characteristic by innovative principles of the theory of inventive problem-solving. In phase III, we can assign the interactions between service components and customer needs to create PSS solution modules. A computer-aided design system environment, called SCO Explorer, is developed based on the above design phases and theoretic concepts to represent a solution design environment with the design requirements and to determine the input parameters of each phase. As the result shows that we verified the usefulness of the design method and tool by applying to existing PSSs by an electronic manufacturer to carry out a PSS solution.

Authors: Hu Fei  , Sato Keiichi  , Zhou Kun  , Zhang Xi  , Liu Zhangsheng
Published: February 2025

Service design methodology has been incorporating methods and tools from multiple disciplines such as ethnography, management, system design and interaction design. Service design tools can be divided into three categories: basic research tools, service analysis tools, and in-depth guidance tools. Although user experience considered to be a key concern of service design, there is a lack of methods to describe profound user experiences and reveal deep meanings to the user. This paper introduces Semiotics Approach for Product Architecture Design (SAPAD) that provides a framework for representing meanings of service activities by adopting Stamper's semiotic ladder model. The semiotic ladder model is composed of six levels: 1) Physical level, 2) Syntactic Level, 3) Empiric Level, 4) Semantic Level, 5) Pragmatic Level, and 6) Social Level. This framework enables thorough exploration of the deep meanings, value and potential contradictions of stakeholders in complex interactive relationships between many system constituents. Through the two case studies of service design for: a) a blood donation vehicle service system, and b) a community elderly rehabilitation service system, SAPAD framework was proved to be very useful and effective for analyzing system inquiry data and synthesizing comprehensive interpretation levels of user experience with clear meaning relevance. Especially representing and understanding profound experience can form a basis for effective integration of trans-disciplinary perspectives critical for achieving integrity and sustainability of service system quality.
Preliminary Design of Product Lines Based on Their Non-Functional Requirements
Authors: Urrego-Giraldo Germán  , Giraldo Gloria-Lucía  , Urrego-Giraldo Olga-Eugenia
Published: February 2025

Moreover of creativity and intuition, the design of products lies on a rational identification and exploitation of Non-Functional Requirements (NFR) of Products. Indeed, the preliminary design must follow strictly the fundamental attributes that constitute true restrictions to an optimal solution. These NFR are not directly operationalizable and it is necessary to define particular mechanisms for operationalizing each of them. The elaboration of a basic preliminary design is not a common activity in the product's lifecycle. Not having a preliminary design miss the possibility of taking early advantage of the information related to NFR, obtained in the definition phase of a solution (product). This omission delays the incorporation of fundamental attributes, troubles the design optimisation process and may increase the design costs. Some questions to be answered by this article are: May NFR determine a preliminary design as a basic design model for products? May the early elaboration of the preliminary design model contribute to reduce the costs and optimize the products' design? NFR determine particular aspects of the preliminary design. This approach was tested for several kinds of products, in particular software products: individual and product lines. The main contributions of the preliminary design are the early taking advantage of the definition phase knowledge of a product, in particular of its NFR; the introduction of preliminary design models in order to contribute to control the design cost, using early fundamental design attributes. A preliminary design model ensures fundamental attributes of the product design and guides the optimization of this one.

Authors: Raudberget Dag  , Ström Mikael  , Elgh Fredrik
Published: February 2025

In most development processes, there is an early phase dedicated to creative concept development aiming at finding solutions to the problem at hand. To arrive at a high-quality solution, several ideas may be conceived and evaluated. However, emerging information and knowledge about product concepts is often not shared on a corporate level since only the final result is documented. This can lead to a significant waste, especially in Set-based design. This paper presents a pragmatic way to structure emerging design information, transferring individual design knowledge to a corporate level. It introduces the Concept Dashboard to track the progress of the concept development and uses an industry standard project workflow system to store and retrieve emerging concept knowledge.
Should Costing: A Holistic Approach from the Product Design to Procurement
Authors: Mandolini Marco  , Favi Claudio  , Germani Michele
Published: February 2025

One of the most important driver for the development of competitive products is the cost. Despite most of the companies are focusing at the procurement stage (strategic sourcing) to reduce the cost of a product, around 80% of the final cost is determined at the design stage. Several software tools are currently available for Design to Cost. On the other side, “should cost” software tools allow to support the procurement phase. However, scienitific and industrial communities are missing an holistic “should costing” framework (method and tool) that accompany the product development process from design until procurement. To overcome this limitation, the paper presents a holistic “should costing” approach that integrates “should cost” and Design to Cost methodologies, covering design, engineering and procurement stages. Since dedicated software tools for “should costing” are required for the right implementation of this methodology, the paper describes stakeholders' requirements for a benchmarking of such tools. The proposed “should costing” frameworjk has been adopted by a couple of companies (product manufacturers), describing their background, deployment process and achieved results. The manuscript ends with a list of the most important benefits of this approach.

Published: February 2025

Information service providers serve to their clients, and customize and integrate new technology into their service to fulfill the needs of customers. Since their needs are various and ambiguous, it is difficult to identify the priorities for functional requirements to be fulfilled and to select technologies to be introduced for satisfying the requirements. This paper aims to support the decision-making process of information technology introduction for information service providers. We employ methods of Systems Approach to articulate users' expectation to reduce the ambiguity and to comprehensively explore technological options to satisfy the expectations. Users' expectation, which consists of functional requirements and non-functional requirements, is determined using stakeholder value network. SVN is created by teamwork with domain experts to unambiguously describe users' expectation. Possible technological options to fulfill users' expectation are comprehensively written down by teamwork function analysis with domain experts. The design options, which consist of possible technological options, are described in function and form options. Visualization of each design option facilitates team discussion, and the decision can be made by team consensus. In case study, we applied the model-based method to the case of Japanese information technology service providers for electric power retailers. As a result of using model-based method, engineers of the firm could share the consensus in target setting process of a project for developing a new function.

Authors: Ferreira L.R.F.  , Campilho R.D.S.G.  , Barbosa D.R.
Published: February 2025

Bonding with adhesives is increasingly being used in the design of mechanical structures. Tubular joints find applications in the piping industry, vehicle frames or thin-walled tubes, for instance, but they are seldom studied in the literature. This work numerically addressed the tensile strength of aluminum tubular joints, after validation of the numerical tool with experiments. The numerical analysis consisted of using the Finite Element (FE) method and cohesive zone models (CZM) to predict the joint strength. Numerically, the effect of the overlap length (LO) and the thickness of the inner and outer tubes (tSIand tSE, respectively) is addressed. The CZM technique was positively validated for the strength analysis of tubular joints. It was also shown that the joints' geometry and type of adhesive highly influence the joints' behaviour.

Published: February 2025

‘LOVE’ model has been recently developed with an aim to assist educators in designing and developing memorable learning programs so that students have an intensive understanding of a particular subject. The model states that the richest learning experience can be stimulated by providing four types of the crucial learning experience (LOVE experience): L-learning, O-observing, V-visiting, and E-experimenting. The model has a potential to contribute in developing student research experience. Therefore, presented in this paper is an attempt to apply the ‘LOVE’ model for assessing student research experience. An online survey on Master's graduate research experiences was conducted. The survey got 33 respondents who are graduates of our department from 2006 to 2015. Their opinions were used in the ‘LOVE’ model for assessment. The results show that there were gaps between expected and gained research experiences that need to be improved. The practical value of this approach is that advisors may be better able to predict and improve for providing the valuable research experiences according to their supervisory styles.

Published: February 2025

The present work has as main objective the proposal of improvement in the process of setup of an agricultural equipment, denominated double mechanized brushcutter, model RO23101 of the manufacturer TATU Marchesan™. The equipment is used to carry out one of the most important activities related to the branch of grass production, i.e., its pruning. For this kind of operation the equipment was designed by the manufacturers with manual and low precise adjustments for height of cuttings. This is used for pruning of vegetation in the plantations and orchards where there is no due requirements with respect to the standard and height adjustment. However, for grass producers, this process of pruning should be treated with greater care, since it is of extreme importance for the development, formation and final finishing of the lawns. For this specific area (lawns) customers are high quality demanding. Therefore, the purpose of this work is to analyze, develop and design a hydraulic cutting height adjustment system, which does not require the direct manual influence of the operator for its adjustment, thus reducing the total equipment setup process time and improving quality performance. The expected result of this work showed a greater performance and agility in the process of setup in the prun0xing of the lawns, as well as the control of its height by means of the hydraulic system.
Holistic Framework for Spatial-Temporal Analysis of Production Schedules
Authors: Semenov Vitaly  , Arishin Semyon  , Petrishchev Konstantin  , Zolotov Vladislav
Published: February 2025

Spatial-temporal (4D) modeling is a promising technology for production planning with many positive impacts not reachable through the usage of traditional methods. Its benefits are better visualization of planned works, better communication among project stakeholders, and better coordination. 4D modeling assists planners in detecting potential problems prior to production phase and thereby reducing reworks, waste and delays peculiar to complex industrial projects. By simulating activities in spatial dimensions and across time, the planners can detect conflicts and avoid possible production problems. 4D modeling tools currently available provide very basic functions to detect collisions among product elements. However, these tools are unable to detect more sophisticated conflicts caused by the absence of supporting or fastening elements nearby, the inability to deliver elements being installed to their eventual positions, the congestion of required workspaces. A complementary set of clash, join, path and workspace conflicts was introduced and discussed in our previous papers from an applied point of view. In this paper a holistic framework for spatial-temporal analysis of production schedules is presented. The framework is a family of mathematical models and computational algorithms intended to identify these conflicts. A particular attention in the paper is paid to the implementation of these algorithms using spatial-temporal indexing and collision detection techniques. Conducted computational experiments with large-scale industrial data confirm the efficiency of the framework that stipulate its introduction into emerging 4D modeling tools. Such tools are expected to improve the spatial-temporal coherence, reliability and trustworthiness of production schedules.

Published: February 2025

Hydrogen fuel cell is used as a rare and sophisticated power source in electric cars. As it was observed in the research carried out on vehicles that use hydrogen fuel cell as a power source and electric motors as sole drive of the car there are some still not solved issues connected with their exploitation. Its working conditions may be unfavourable in case of external factors, which influence is not neutralized. In order to improve and stabilize the conditions additional components (active or passive) somehow cooperating with adequate space and operation environment of the cell are developed. This article is a response to the need for design of air supply channels for the hydrogen cell. The optimization subject is the proper channel shape in order to achieve the appropriate direction of the air stream inducing the forced exchange due to the high temperatures of propulsion heating the air around the cell and interrupting its working conditions. Especially important in this study, it is the fact that developed supply system is designed for high performance electric vehicle with very low air resistance. Accordingly, the critical requirement is to ensure the lowest possible influence on the vehicle aerodynamics keeping the performance of the air supply system. This type of multi-criteria optimization problem, combines the analysis of the geometrical relationships, the use of mathematical models that allow to designate the load states at specified operating conditions, and verification of endurance. It requires special methodology, coupling of used tools and advanced optimization algorithms.
A Design Methodology for a CSP-Based Optimization Approach
Authors: Cicconi Paolo  , Nardelli Miriam  , Raffaeli Roberto  , Germani Michele
Published: February 2025

Design optimization is a common practice in industry. Different mathematical algorithms have been developing to support the optimization in engineering design. The integration between optimization methods and simulations is an interesting issue in engineering design. A typical optimization workflow can include simulation steps; however, the Virtual Prototyping analysis is more time-consuming than analytical calculations. The study of Constraints Satisfaction Problems is a mathematical topic which can be applied for solving engineering issues in design. The strength of this approach is the velocity on searching the satisfied solutions. This paper proposes a design methodology which considers the use of CSP models and calculation tools to optimize the sizing of columns and beams in the design of a steel structure. The calculation tools regard analytical models and numerical analysis. While the analytical approach regards the computing of cost and weight, the numerical analysis is used to verify and check the engineering performance in terms of deformation and stress state. A customized application, based on MiniZinc platform, has been developed and proposed to solve the CSP model for a test case steel structure. The CSP problem has been limited to the calculation of analytical constraints such as cost and weight. Finally, the resultant set of solutions has been evaluated using numerical solution to complete the optimization analysis.

This paper talks about how to plan efficient delivery route by analyzing drivers' behavior. Today, as E-commerce services represented by Amazon are growing, demand of delivery service is getting bigger. It is a problem that not only the amount of delivered baggage is expanding, but also the level of delivery service is rising. On the other hand, the number of drivers is reducing because of a low salary and poor working conditions. From these background, it is required to improve efficiency of delivery to keep delivery service. Especially in urban areas, the most time-consuming work in last mile delivery is not moving between customers by a truck but work occurring after parking (including parking). In spite of this, many researches focus on how to minimize the total time of moving between customers, like solving traveling salesman problem (TSP). So this paper has tried analyzing drivers' “parking behavior”, consisting of a successions of behavior such as searching for parking place, parking a truck, taking out baggage from a truck and visiting customers to entrances.On this paper, I have tried analyzing by following steps. First, I have detected each parking behavior from the GPS data of the trucks by 2-stage clustering method, which has resistance to noise. Next, I have matched each parking behavior with each customers. Then, I can analyze how drivers decide parking behavior by customers, and we can plan efficient delivery routes.

Eco efficiency is an important concept in order to decouple environmental consciousness from product development. It often happens that large environmental impact occurs in producing design features that is not really important for customers. Product design should be reviewed based on the value of each design feature versus environmental impact, so-called eco-efficiency. This study focuses on smartphone design as a case study and evaluates eco-efficiency of each design feature. The paper first evaluated the weights of seven different design features regarding functions and outlook of the products. The 7 design features are “memory size,” “display size,” “battery capacity,” “resolutions of camera,” “texture.” “color” and “customizability” which means varieties of optional parts. The evaluation was carried out by conjoint analysis. Effect by enhancing each design feature on the customers' preference was evaluated. Then, the paper calculated CO2emissions in order to increase the design features from the lower level to the upper level. Based on the value weights and CO2emission, eco-efficiencies of the design features were calculated. The result showed that basically functionality is more important than visual features. However, it also clarified a certain design feature such as “color” is more eco-efficient than a certain design feature such as “memory size.”

Automobile reuse parts are recovered from end-of-life vehicles and are commercialized by visual checking and cleaning. Generally, reusing parts can reduce the cost, material consumption, and environmental load. However, as the value and performances of automobile reuse parts are lower than those of the new parts, reusing automobile parts is not always advisable from the viewpoint of the product value, environmental impact, and cost throughout the entire life cycle. This study proposes appropriate repair options for customers (reuse parts or new parts) over the entire life cycle of their automobiles. The combined value, environmental impact, and cost of the product are comprehensively assessed by the total performance evaluation index. As a case study, the paper discusses an appropriate repair option based on the scheduled use period of a customer's automobile engine after repair.

Due the increase of demand for the optimization of productive processes and the use of information at industries. Based on this, it has been highlighted some initiatives that are being adopted by manufacturing, such as Predictive Maintenance, focused on increasing the useful life of equipment to get a more flexible production. The predictive maintenance has the purpose of, with the support of relevant data collected through smart sensors, constructing a diagnostic which allows any maintenance staff to comprehend a machine's health and plan possible interventions in the production line. However, it has been noticed that there are numerous challenges in implementing this concept in corporations due to unmeasured technical, organizational and cultural factors. The objective of this article is to evaluate the capability of the Industry 4.0 technologies in relation to the functional requirements according to the PoC (Proof of Concept) of Predictive Maintenance within the automotive industry for the construction of a Referential Architecture. It was developed through the association of attributes, functional requirements and applicable technologies supported by multi-criteria analytical decision-making methods (MCADMM). The RAMI 4.0 framework was used to structure the layers of strategic implementation of the initiatives belonging to Industry 4.0 (I4.0). Specialists were consulted, through a Survey, to collaborate on the evaluation of the relational framework between functional requirements and applicable technologies. The results presented which are the most significant technologies at each strategic level of RAMI 4.0, thus characterizing a Referential Model for Predictive Maintenance initiative in the automotive sector.
