Integration of Learning Activity and Process-Oriented Assessment to Promote the Self-Directed e-Learning
Authors: Wang Xiaofeng  , Yu Shengquan
Published: February 2025

To promote learners' effective engagement in e-Learning course, this study designed and implemented an e-Learning course named Novice Teachers' Educational Technology Training Course for 279 teaching novices in a self-directed e-Learning environment. As students were engaged in the tasks, we monitored their engagement and conducted an evaluation on a micro-video that the students created by the two course designers. The study found that: 1) Process-oriented assessment which are behavioral engagements in self-directed e-Learning course can promote learners to finish the learning activity and get high scores. 2) High-level behavioral engagement does not equate to high-level cognitive engagement while learners' cognitive engagement is more important than behavioral engagement. 3) There exists differences between high-level and low-level learning achievement in the cognitive engagement of learning activities. High-level achievement learners are more actively participating in learning activities, such as reflection, doing, discussion and publishing works. Therefore, for course designers, they should design more learning activities which go from absorption to participation and to creation.

Authors: Zhang Shumei  , Callaghan Victor  , Wang Hongmei
Published: February 2025

Professional English is a mandatory module in all Chinese universities, being taught alongside the students major. However, students often find learning English somewhat tedious as it can seem disconnected from their major and aspirations for the future. To try to overcome this shortcoming we have introduced the use of creative science as a means of linking language learning to exploring futuristic technologies with the aim of fuelling their engagement with language learning while at the same time helping them acquire valuable creative-thinking skills. In this paper we describe a two year trial be conducted at Shijiazhuang University where we operated this scheme with two batches of students, reporting our findings which show this approach produces significant learning gains over traditional methods. Finally, we describe our plans for developing an online EFL facility based around an i-Lab in the form of a virtual spacestation.
Q3D-Game: A Tool for Training Users' 3D Spatial Skills
Authors: Falomir Zoe  , Oliver Eric
Published: February 2025

This paper presents a computer game developed to apply the qualitative model for describing 3D objects (Q3D) using depth and different perspectives. The Q3D-Game shows how to build objects out of cubes; and how the top, front and lateral views of an object can be extracted. It also explains the differences in depth in each perspective and relates them to the Q3D model. This knowledge is acquired by the system enabling it to infer perspective features of 3D objects by consistency checking. The Q3D-Game also motivates users while playing so that they train and improve their spatial abilities. These abilities are trained using tasks such as 3D object block building and answering questions from the Perceptual Ability Test (PAT, part IV) which measure intelligence in humans. The Q3D-Game testing process by humans is currently in progress.

Authors: Pereira Ana Filipa  , Nicolau Maria João  , Costa António  , Macedo Joaquim  , Santos Alexandre
Published: February 2025

For the needs of future Internet, many researchers are proposing a paradigm shift towards a new information-centric approach. The Named-Data Networking (NDN) is one these proposals. Instead of addresses, packets should use only names, either expressing interest on specific information or naming the data content carried in. Applying the NDN model in a mobile ad-hoc network can greatly simplify the routing, since there is no need for global addresses and all nodes in the network can cache data packets.
Optimizing Load Balancing Routing Mechanisms with Evolutionary Computation
Authors: Pereira Vítor  , Rocha Miguel  , Sousa Pedro
Published: February 2025

Link State routing protocols, such as Open Shortest Path First (OSPF), are widely applied to intra-domain routing in todays IP networks. They provide a good scalability without lost of simplicity. A router running OSPF distributes traffic uniformly over Equal-cost Multi-path (ECMP), enabling a better distribution of packets among the existent links. More recently, other load balancing strategies, that consider non even splitting of traffic, have been put forward. Such is the case of the Distributed Exponentially-weighted Flow SpliTting (DEFT), that enables traffic to be directed through non equal-cost multi-paths, while preserving the OSPF simplicity. As the optimal link weight computation is known to be NP-hard, intelligence heuristics are particularly suited to address this optimization problem. In this context, this work compares the solutions provided by Evolutionary Algorithms (EA) for the weight setting problem, considering both ECMP and DEFT load balancing alternatives. In addition to a single objective network congestion optimization problem, both load balancing schemes are also applied to a multi-objective optimization approach able to attain routing configurations resilient to traffic demand variations.

Gamification and the Improvement of Urban Sustainability
Authors: Silva Fábio  , Analide Cesar
Published: February 2025

An information centric society needs means to improve itself by taking advantage of the communication channels and knowledge it possesses. Smart-cities provide some of the response for this problem, but the aims remain open and generic. Taking the case study of urban transports and urban driving, there are already projects that generate and analyse data, but the information is often only disclosed to the user. Exposing some sort of this information to a community may lead to a faster behavioural modification. The fundamental objective of this work is to use the information acquired to improve awareness and behaviours in these societies. From this perspective, information tools such as gamification, user and community awareness are discussed in relationship to urban transports applications. The aim is to generate improved habits in a society using non-intrusive methods as mandated by smart-city design.

Analysis of Differences Between Perpendicularity Measurements Applying ISO 1101/2012 and ASME Y14.5-2009 and Its Impacts
Authors: Baker João  , Sesselmann Meinhard
Published: February 2025

The dimensional variations inherent in a manufacturing process are the reason for the existence of the acceptance tolerance concept on a product characteristic. The geometric quotation system has many advantages over the Cartesian system by avoiding ambiguity in the interpretation on form, orientation and location errors. The two main standards that define the geometric quotation on a mechanical design are ISO1101/2012 and ASME Y14.5-2009. However there are differences in interpretation even when the same symbols are mentioned by these standards. It is, therefore, important to know these differences to ensure the quality for companies that provide products to customers who apply different standards of geometric control. This article presents the results of perpendicularity control using each standard and their difference as an example of the impact when choosing one of them. In addition, the article shows preliminary results of a still on-going survey indicating that these differences between the standards are still little known among professionals in the areas involved in Brazil.

Authors: Riz Gustavo  , Santos Eduardo Alves Portela  , Loures Eduardo de Freitas Rocha
Published: February 2025

Healthcare processes are complex and require a high-level of interdisciplinary cooperation among the different specialists and sectors involved in their delivery. Information flows among organizational entities, sectors, areas and employees represent possible low process interoperability risks as well as noncompliance risks between business rules and actual process deliveries. Besides this complexity, the Brazilian healthcare area has a notorious problem in its public and private health care systems. These problems are of structural, organizational and financial natures, reflecting the low value attributed to quality and to the actual services in recent surveys of Instituto Data Folha and the Brazilian Ministry of Health (Ministério da Saúde). This paper intends to propose an adaptation of Process Mining as an ancillary tool in knowledge discovery processes in healthcare in order to contribute to further improving this area in Brazil. In order to accomplish this, a case study was carried out in the Erasto Gaertner Hospital, located in Curitiba – PR, Brazil, a local reference in cancer treatments.

Authors: Levandowski Christoffer  , Müller Jakob R.  , Isaksson Ola
Published: February 2025

This paper presents a set-based approach to use functional models for platform concept development to identify feasible modules at early design stages. The concepts are defined using functional requirements, design solutions and their interconnections. These models are then encapsulated into functional modules through clustering of Design Structure Matrixes (DSM). A metric is introduced to quantify the ability to modularize a certain concept, which may be used to assess and eliminate inferior concepts. The approach is illustrated using a case study from the aerospace industry. The result shows that modules can be identified by clustering of the functional structure. This has an integral effect on early division of work, possibility to design reuse, etc. The ability to modularize a specific concept The case study also shows that, despite of the traditionally integrated character of the product studied, it is possible to identify functional modules for reuse in a platform.
Models of Impact for Sustainable Manufacturing
Authors: Peruzzini Margherita  , Pellicciari Marcello
Published: February 2025

Design for Sustainability (D4S) and LifeCycle Assessment (LCA) methods usually focus on one single aspect of sustainability at a time (e.g., environmental issues, ergonomics or costs) and are usually applied when the industrial system is already created, so that only corrective actions can be taken. In this context, the present research highlights the need of predictive methods to design sustainable system, able to provide an early holistic assessment from the early conceptual stages, and defines a set of models of impact able to assess all aspects of sustainability (i.e., environmental, economic and social) by proper key performance indicators (KPIs) from the early design stages. An industrial case study is presented to show the application of the proposed models on industrial manufacturing systems and demonstrate their validity in estimating the global impact on sustainability, including also human factors.

Authors: Mantese Gabriel Couto  , de Piere Bruna Aparecida  , Amaral Daniel Capaldo
Published: February 2025

Industrial symbiosis is the exchange of by-products, energy and water between industries, centered on a collective approach, and in order to achieve competitive advantages. It is central to the concept of Eco-Industrial Park (EIP) and requires continuous monitoring of the professionals involved. Performance indicators for the measurement and monitoring of industrial symbiosis have been proposed and identified in the literature, however there is no consolidate indicator that is widely used in practice. These indicators require validation in order to evaluate and choose which options are able to measure the industrial symbiosis. There are two types of indicators validation, the conceptual validation and the empirical validation. This study investigates the integration of the conceptual validation and the empirical validation in the evaluation of the industrial symbiosis indicators. It is proposed the combined use of an indicator validation methodology based on expert judgment, the 3S Methodology, and a simulation technique, the Agent-Based Modeling (ABM). The proposed procedure aims to validate any indicator of industrial symbiosis, providing specific criteria to the evaluation.

Published: February 2025

Additive manufacturing technologies are still brand new in industrial production. Although It has widely been used in prototypes development, either low or very low scale production are also able to incorporate such technologies nowadays. The application of additive manufacturing in large scale has been presented as a paradigm to be overcome. Nevertheless, the application of these technologies worldwide might affect production systems dynamics in addition to organizations structures. At the same way, applying additive manufacturing technologies in medium and large scale might also create either novel businesses models or improve marketing segments that were underestimated. For that reason, the main goal of this paper is to investigate the metrics applied in additive manufacturing to identify the main advantages and disadvantages of these scenarios in a systematic study which correlate the economic, social and environmental key points which provide current manufacturing companies to identify the suitability of each additive manufacturing technology in accordance with its business goals. Therefore, the sustainable metrics for additive manufacturing processes will prove that it is really a sustainable manufacturing. Moreover, these results were results of others preliminary studies which might open a new discussion topic among manufacturing companies.

A Notification-Oriented Approach for Systems Requirements Engineering
Authors: Simão Jean M.  , Panetto Hervé  , Liao Yongxin  , Stadzisz Paulo Cézar
Published: February 2025

Systems Engineering (SE) is an approach for designing complex systems in a multidisciplinary universe, based on concepts from the systemic paradigm and promoting languages, methods, and standardized processes. Requirements engineering is one of the main steps in SE processes. The current research presented in this paper aims at focusing on the open issue related to the formalization of systems requirements for their verification, ensuring the coherence of the whole set of requirements in each contextual engineering domain and their validation against the initial stakeholders' needs. Moreover, requirements coming from different domains are generally linked by non-formalised traceability relationships. It is even difficult to trace any change in their definition and their impact to the whole set of specifications. The paper discusses and proposes an approach for systems requirements engineering based on a rule and notification oriented approach for ensuring the effective coherence and understanding of these requirements throughout the life cycle of any complex system. This proposed notification approach is derived from the so-called Notification Oriented Paradigm (NOP), a new rule and event driven approach for software and hardware specification and execution.

Published: February 2025

Micro and Small Companies (MSC's) have an important role in world's economy, despite the challenges they face. One of them is the absence of adequate human resources and formal work procedures as the New Product Development Process (NPDP). This fact is critical for its competitiveness with large ones, who have some repertoire and elasticity while addressing the critical user needs. This work aims to propose a simplified procedure to address informational design in MSC's. It was based on a comparative study between four traditional NPDP models and formalized into a didactic bundle, consisting of Excel Sheets. It was applied in a pilot experiment within a Small Company and the designers' opinions were collected through a questionnaire. The effect of the proposal was checked past 18 months, with an interview. The manager reported, despite the benefits perceived with the training, they still do not apply any kind of NPDP methodology in the company. Nevertheless, he concluded that a regular presence of a consultant would be required to change the situation.

Published: February 2025

The assignment of the right fixtures to their corresponding workpieces and the determination of their stable flows is one of the important challenges for manufacturing systems. This problem has not been well addressed in the past publications. This paper aims to address this problem using an on-demand fixture assignment and control method. A decision support system (DSS) is presented so as to address this problem. This DSS integrates the case-based reasoning (CBR), rule-based reasoning (RBR) and fuzzy set theory components of an artificial intelligence (AI). Cases are represented with an object-oriented (OO) approach in order to characterize them by their feature vectors. A fuzzy weighted Euclidean distance measure is applied for case retrieval. Numerical example is also illustrated to show the applicability of the proposed DSS.
Design of Software Development Architecture Comparison of Waterfall and Agile Using Reliability Growth Model
Authors: Hiekata Kazuo  , Mitsuyuki Taiga  , Goto Takuya  , Moser Bryan
Published: February 2025

This paper proposes a method for deciding whether to insert an agile process as part of a waterfall project. Recently, many software projects adopt an agile software methodology. Still, some software is developed with traditional waterfall methodologies. Agile methods claim a strength of flexibility for uncertain changes, yet in some cases the initial expected scope of the project cannot be realized or undetected errors remain because schedules are fixed and unexpected backlog of tests and bug fixes remain unaddressed. On the other hand, a waterfall methodology can include high risk of violating schedule targets, while fulfilling the initially expected scope with comprehensive tests so that more complex products are reliable. For the decision whether to develop in waterfall or agile, our approach is to evaluate the effects on uncertainties by adoption of agile techniques. We begin with focus on uncertain rework. The effects on rework are evaluated as cost using simulation. The decision making problem is modeled as a decision tree. In the simulation, a Software Reliability Growth Model is used as an error likelihood and detection model. This proposed method is demonstrated using a simple shopping web site. As a case study, the effects on rework by adoption of agile can be evaluated using the developed simulator. With comparison of predicted rework costs given a balance of waterfall or agile methods for a specific case, the project can be designed more effectively.

Published: February 2025

In recent years, many e-commerce websites provide consumer feedback functions and social networks, allowing customers to share their purchasing and usage experiences online. Companies collect and analyze information from customers' reviews through the platform to understand the customers impressions of the products they purchased. Online customer reviews has been widely regarded as an important source of information influencing customers buying decisions. In addition, online customer reviews help companies to redesign their products with key features that better positions to target customers in promising market sectors. This research uses online customer reviews as the business intelligence (BI) corpus. After determining the source webpage of customer reviews, a web crawler is needed to collect customer review text. Afterwards, computer-assisted text mining, clustering analysis, and perceptual mapping are applied to develop a formal methodology to compare similar products in a given domain. In this research, the consumer electronic sector is studied. Mobile phone customer reviews are web crawled, collected, mined, and analyzed. The study assists mobile phone manufacturers to understand the voice of customers in both positive and negative perspectives of post-purchasing experiences. The customer-preferred product functions, hardware/software/app features, and price positions, as key business intelligence, are derived for new product designs and market launches.

Discussion on Generic Innovation Models and New Product Opportunity Identification
Authors: Kampa Josmael Roberto  , Cziulik Carlos
Published: February 2025

Ideas and opportunities are often seen as the same, but there are differences and shared similarities that imply on the way one can achieve and research about them. Creative solutions by creative people are always welcome and can be somewhat improved by technical training or crowdsourcing. However, the recurrent ability to address or to be driven by the value spark that makes the idea a winner still demands research and tools. A new valuable product idea is a complex entity. This paper presents a brief investigation of theoretical innovation models with a focus on its mechanisms for identifying new product opportunities. The work aims to complement partially the research conducted by Kampa [1], which features an emphasis on approaches presented by classical New Product Development Process (NPD) models. An exploratory study was conducted on generic innovation models and its main stages in order to identify how new product opportunities are treated in them. It was seen that few procedural detailsare offered, and that the topic has been mainly discussed on idea management models. Despite their aim on the idea part of the equation, it is clearly noted that the opportunity identification mechanisms should be investigated within these areas, somewhat segregated as sources on NPD researches, and should involve works on idea management models and open innovation models.
Integrated Approach Bridging PLM, ERP, SCM in Automobile Industry
Authors: Hatakeyama Kazuo  , Machado Marcelo
Published: February 2025

New Product Development (NDP) is a major source of competitive advantage to automobile manufacturers. More specifically, Product Lifecycle Management (PLM) has proven to have a positive impact on the effectiveness of the product development effort. One of the many reasons for that is the fact that PLM requires detailed attention to the constraints a firm will face, depending on the stage of the product. Widely accepted references outline the important of decision making in PLM. This trend is also is reinforced by the number of research projects in known, global centers of excellence in product development and innovation. Enterprise Resources Planning (ERP) approach is in the stake to supply the plan to best use of resources allocated to the project. Another revered trend is the idea of integrating the whole supply chain from a value-adding perspective. Thus, the Supply Chain Management (SCM) and Manufacuturing Engineering Systemas (MES) of current and new suppliers for newly developed parts or products are the key players for the competitiveness in the market. Conversely, strategies, methodologies, and PLM tools present themselves as agile, lean, safe yet collaborative approach to NPD. This paper presents an integration of ERP into PLM with a special emphasis on SCM. The automobile industry, as an example is to contextualize the discussion.

Published: February 2025

The objective of this work is to present and to discuss the potentialities of a transdisciplinary process modeling methodology, which has been named T-PROST Framework, to support the product design phase processes (production and management) in the systems concurrent engineering lifecycle. The methodology consists in creating a conceptual reference model of the systems concurrent engineering lifecycle processes and to transform it into specialised models of the areas of (Model Based) Systems Engineering, Project Management, Business Process Management and Simulation Modeling. The main benefits generated by the approach are derived from: The systematisation of the model development, encompassing both the systems engineering processes and their management; The use of the T-ProST Framework for model implementation and analysis, based on the simultaneous use of diverse disciplines and their respective methodologies and tools; The joint assessment of the specialised models created to provide better solutions and to improve project development. The T-ProST Framework can be used for the implementation of generic environments, made by the ensemble of applications implemented with the specialised tools used in the diverse disciplines. These generic environments can be used to perform product lifecycle management by organisations conducting short lifecycle project developments, characterised by low and mid-level complexity scopes submitted to severe time and budgetary constraints, as an alternative to the use of complex, expensive and difficult to configure proprietary systems existing on the market.
Enterprise Integration of Engineering Systems for Defence Related Projects

Published: February 2025

Defence Projects world-wide are undergoing a gradual transition from development projects to those involving integration of COTS and Military-Off-The-Shelf (MOTS) Systems. At the same time Requests for Tender (RFT) solicit Innovative Support Solutions to reduce Life Cycle Cost (LCC) over thirty years of operation. While there are defined processes to support both Systems Engineering and Support Engineering, these are hierarchical by engineering discipline and do not provide the means of architecting and trading off system design and support objectives concurrently. This study analyses the suitability of existing engineering processes and builds a model of the current state process set and artefact relationship and compares these with the international standards against the goals of reduced Life Cycle Cost (LCC). This reserach identifies the transitional needs and proposes changes to the Enterprise Business Management System processes, tools and work product templates to achieve concurrent system and service solution engineering.
Development of a Web Platform for Casting Process Selection

The choice of the right process for casting components is a complexactivity, and impacts directly on the design and manufacturing of the product. A single failure in the casting process selection can increase design and production time and, in critical cases, result in a collapse of the manufacturing and assembly of components. This process is usually based on guidelines scattered in the literature, or based on the designer's accumulated experience, but this action could be carried out by software containing a casting process database that can be employed during the product development stage, assisting the designer. In this context, our goal is to adapt a method for selection of casting processes previously developed into a web platform to support casting process definition. The adopted selection method uses Quality Function Deployment (QFD) and Design for Manufacturing (DFM) principles to provide a structure to support casting selection decision based on part features and process demand. The proposed software was developed for the Web using HTML and JavaScript, providing better usability than the previous format of the proposed selection method using spreadsheets. For validation, ferrous and nonferrous cast parts were analyzed using the proposed web platform. The results were compared with the selector provided by the American Foundry Society and with processes actually used in the industry. Thus, the results showed a good relationship with the other methods, also providing a quantitative classification (prioritization) of the results. In addition, this software supports the design of the manufacturing process by means of a checklist to adapt the part to the metal casting process presented to the designer.

With their response to the market and regulatory challenges, modern enterprises have introduced and continuously improved processes, methods and tools to feed the individual needs of their business domains, multidisciplinary teams and supply chain, mastering the growing complexity of virtual product development. As far as product data are concerned, data exchange, 3D visualization and communication are key processes for reusing manufacturing intelligence across lifecycle stages. User-friendly access to the increasing amount of information plays an essential role in business and leisure. Several CAD interoperability and visualization formats meanwhile have been developed to support product development strategies. Such activities also include national and international associations and standardization bodies. The emerged methods and systems aim to increase the performance, acceptance, and user experience of graphical data representations for a broad range of users. This paper analyses methods and tools used in virtual product development to leverage 3D CAD data in the entire life cycle. It presents a set of versatile concepts for mastering exchange, aware and unaware visualization and collaboration from single technical packages fit purposely for various domains and disciplines.
Designing Eco-Effective Reverse Logistics Networks

Published: February 2025

Reverse Logistics Networks (RLNs) have grown in importance after return policies became compulsory. Lately, questions have been raised whether they are as helpful to the environment as possible. Efforts have been conducted to optimize RLNs in terms of their eco-efficiency, minimizing costs and emissions; still, results are not advancing with the necessary speed. Alternatively, the eco-effectiveness (“doing the right thing” for the environment) approach emerges, promoting a supportive relationship, balancing environment and economy. This research aims to model the design (or redesign) process of eco-effective RLNs. There are numerous ecodesign tools focusing on product or service design, but an eco-effective design process conceived specifically for logistics network design purposes has yet to be delivered. Research was carried out using the Design Science Research Methodology and an exemplification was outlined to demonstrate how the process unrolls. The model was conceived using a combination of the TRIZ method, Upcycling and Industrial Symbiosis. Eco-efficiency of these networks was not evaluated. The proposed design process model will help the conception of more innovative, eco-effective logistics networks.
