Path planning based on map matching in UAV/UGV collaboration system
Authors: Huo Jianwen , Zenkevich Stanislav Leonidovich , Nazarova Anaid Vartanovna , Zhai Meixin 
Published: September 2019

PurposeUnmanned aerial/ground vehicles (UAV/UGV) collaboration systems are increasingly being used to perform reconnaissance and rescue missions autonomously, especially in disaster areas. The paper aims to discuss this issue.Design/methodology/approachTo improve visibility, this study proposes a path-planning algorithm based on map matching. Continuous ground images are first collected aerially using the UAV vision system. Subsequently, a global map of the ground environment is created by processing the collected images using the methods of image correction, image mosaic and obstacle recognition. The local map of the ground environment is obtained using the 2D laser radar sensor of the UGV. A set of features for both global and local maps is established. Unknown values during map matching are determined via the least squares method. Based on the matched mapping, the traditional A* algorithm is used for the planning of global path in the global map, and the dynamic window method is used for adjustment of the local map.FindingsSimulation experiments were carried out to demonstrate the effectiveness of the proposed algorithm. The experimental results show that the proposed algorithm can construct a global map of the wide environment and effectively bypass the obstacles missed by the UAV.Research limitations/implicationsPrior to map matching, there is a need to extract the edge of obstacles in the global map.Originality/valueThis paper proposed a path planning algorithm based on map matching, yielding insights into the application of the UAV/UGV collaboration systems in disaster areas.
Next decision node (NDN) planning: an ambidextrous planning model
Authors: Usher Greg S. 
Published: September 2019

PurposeThe purpose of this paper is to address calls from within the existing literature for a planning model that can provide both control and flexibility in dynamic environments.Design/methodology/approachThis research adopts a two-phase grounded theory methodology. Phase I tests a hypothesis through a structured online survey. Phase II tests a new planning model through a focus group and an online survey.FindingsThis research finds that client-side project managers misapply rational planning tools when managing construction projects. It also finds that the planning artefacts created in the initial stages of a project are used as a communication tool, rather than a controlling or monitoring tool. These findings provide an opportunity for new planning models, such as the (next decision node) NDN model, to be adopted. These planning tools can create new levels of transparency and accountability within the planning process – as well as provide a model which is more closely aligned with the practitioners “lived experience”.Research limitations/implicationsThe NDN model provides a foundation for further research into the micro-mechanisms of organisational ambidexterity in projects and refinement of the NDN model.Practical implicationsThis research presents a new planning model which practitioners can adopt when delivering construction projects.Originality/valueThis paper presents a new, ambidextrous planning model grounded on the “lived experience” of client-side project managers.
An empirical assessment of relational contracting model for supply chain of construction projects
Authors: Jagtap Milind , Kamble Sachin 
Published: September 2019

PurposeThe purpose of this paper is to examine how the client–contractor relationship affects the project performance in light the theory of relational contracting. The empirical study evaluates the effect of project trust (PT) mediating through the dyadic factors and procurement-specific factors (PSFs) on the project performance.Design/methodology/approachResearch design is carried out in three phases. The first phase of review of literature has identified the key constructs of the study and the conceptual model is formulated. Subsequently, the constructs of the study are validated through expert opinion and pilot study. In the third phase, the questionnaire of the study is administered on 320 samples in various cities of India. The exploratory factor analysis and confirmatory factor analysis is carried out on the two different sample sizes. The structural equation model is finally tested with satisfactory fit.FindingsPT not only improves the dyad factors in construction supply chain (CSC), but also influences the project performance. However, project risk and relationship commitment are not associated with enhancing project performance directly. PSFs and dyad factors are the two mediators in transforming PT into relationship commitment and project performance. Client-led supply chain initiatives and contractor-led supply chain initiatives differ in the CSC.Research limitations/implicationsThe present research has employed behavioral data to understand the effect of project procurement on project performance. Nevertheless, future studies should use objective data to support the constructs of the study. This study outlines the common and socially rooted relational governance of the project. This study is useful to the clients, contractors and policy makers in understanding the interplay of various control mechanisms to ease the procurement of large and complex construction projects. Future studies should focus on separating client-led control mechanisms and contractor-led control mechanisms of the relational contracting and its effect on project performance.Originality/valueThe research study contributes in formalizing the governance structure of supply chain in dealing with the complex construction projects. The study has contributed in understanding the client-led initiatives and contractor-led supply initiatives of establishing the supply chain of construction projects. It has demonstrated the mediating role of dyadic factors and PSFs in improving the project performance.
BIM mediation and users’ behavior
Authors: Voordijk Hans , Sloot Ruth 
Published: September 2019

Purpose
With building information modeling’s increasing influence, it becomes important to analyze building information model (BIM)’s impact on users’ behavior. Therefore, the purpose of this paper is to explore BIM’s influence on users’ behavior, using the innovative philosophy of technical mediation. This philosophy implies that perceptions and actions are always, to some degree, constituted and transformed by technologies. The question in this study is how the perceptions and actions of users are mediated by BIM.

Design/methodology/approach
A framework developed by Dorrestijn to assess the impacts of technology is used to explore the different types of impact that BIM has on the perceptions and actions of its users. Through a literature review, this framework is used to categorize the mediating effects of BIM. Following this, expert interviews, a workshop and user interviews explore these effects in practice.

Findings
Based on Dorrestijn’s framework, it is concluded that guidance and persuasion are important mediating effects of BIM. BIM also impacts the human decision-process through coercive pressures to implement BIM and to embody BIM through acquiring skills.

Originality/value
With the increasing influence of BIM, analyzing its impact on users’ behavior becomes increasingly relevant. This is the first study to use the technical mediation approach to analyze this impact. In this approach, humans and technologies are seen as interacting with and co-shaping each other.
Understanding the components of profitability and productivity change at the micro level
Authors: Wiech Bernd Andreas , Kourouklis Athanassios , Johnston James 
Published: September 2019

Purpose
The purpose of this paper is to present a refined framework providing clarity in terms of the components of profitability and productivity change from the perspective of the firm level.

Design/methodology/approach
The literature is analysed with a scoping study and a systematic literature review. Productivity measurement approaches are compared using data at the product level.

Findings
The definition of total factor productivity (TFP) in the literature negatively affects the accuracy of profitability and productivity measurement. In the usual case of a dynamic output mix, TFP change encompasses biasing output mix effects relating to profitability, but not to productivity change. Therefore, this paper defines changes of a ratio of output quantities to input quantities not as TFP change, but as quantitative profitability (QP) change. A framework is proposed decomposing profitability change into price recovery and QP change, whereas the latter comprises of valid productivity change (encompassing technological, technical efficiency and productivity-related scale effects) and output mix change (encompassing proportion, quality, output switching and profitability-related scale effects).

Research limitations/implications
Future research should include literature from the industrial organisation field of economics. The presented framework should be transferred to the standard production function framework used in economics.

Practical implications
The paper can help preventing faulty decision making or distrust due to the use of biased profitability or productivity indicators. TFP-based productivity indicators are unsuitable for most firms. To measure productivity meaningfully, firms should use adequate approaches (e.g. standard input- or adjusted total factor productivity-based ones).

Originality/value
The paper contributes to a more accurate performance measurement approach, as researchers and practitioners better understand the components of profitability and productivity change.

Authors: Hamzah Mohd Syahir Anwar , Austad Azhan , Razak Saiful Izwan Abd , Nayan Nadirul Hasraf Mat 
Published: September 2019

Purpose
Over the years, electrical stimulation in drug delivery system holds particular interest in producing spatially and temporally controlled release mechanism. These systems helped in localized doses drugs to be administrated and response efficiently at target site to achieve excellent healing effect in control microenvironment. Extensive research is needed in order to develop versatile electroactive biomaterials in the field of therapeutics applications. This paper aims to discuss this issue.

Design/methodology/approach
This work reports the development of polycaprolactone (PCL) electrospun coated with pectin/polyaniline (PANi) composite, which has been characterized and whose drug delivery application is ascertained. The composite has been characterized on its mechanical conductivity and wettability properties to evaluate best formulation. The analysis on morphological properties using scanning electron microscope (SEM) confirmed the formation of the dual-layer electro-responsive composite.

Findings
Among different formulations studied, the pectin/PANi composition (12 percent/3 percent) was found to be an optimized composition with ultimate tensile strength of 55.48±0.65 MPa and modulus strength of 63.30±0.43 MPa with 2.41×10–3 Scm−1 electrical percolation. The hydrophobic PCL electrospun reduced as coating material was introduced on top with optimum of 85.3 percent degree of swelling and water contact angle at 39.17±0.67°. SEM micrograph revealed strong interaction between dual-layer structures with interconnected porous of uniform fibers.

Originality/value
Overall, these data present a multiangle initial characterization of this novel dual-layer electro-responsive composite for applications in drug delivery. However, additional analysis should be performed in order to provide a clear verification as drug delivery scaffold.
The dominance of water on lubrication properties of articular joints
Authors: Göçerler Hakan , Pfeil Bernhard , Franek Friedrich , Bauer Christoph , Niculescu-Morzsa Eugenia , Nehrer Stefan 
Published: September 2019

Purpose
The paper aims to focus on the individual contribution of water to the lubrication regimes in articular joints because understanding of these regimes is crucial not only for the treatment of diseases like osteoarthritis but also for the development of new implants to have a longer service cycle.

Design/methodology/approach
Cartilage specimen and the synovial fluid were both isolated from bovine knee joints that are enclosed by a synovial membrane under sterile conditions of a biosafety Level 2 (BSL2) cabinet. Subchondral bone was removed from the cartilage because it not only creates a stable base to place the specimen on the holder, but it also acts as a primary shock absorber protecting the overlaying cartilage under high-impact loads. A specimen holder specially designed for tests and was attached to the linear oscillation (SRV) test machine. The SRV test machine provides a reciprocating sliding motion between the cartilage samples that are submerged into the selected biological media. The entire system can be mounted on the BSL2 cabinet, sealed with the convoluted gaiter and transported to the SRV machine with a specifically designed handle for the entire system. The process ensures sterile conditions for tests on biological samples that are highly sensitive to the environmental conditions.

Findings
A remarkably low coefficient of friction value for distilled water constitutes more evidence to support the assumption of the impact of water in the friction behaviour of the cartilage-against-cartilage contact. As the fluid in articular cartilage (AC) effectively serves as a synovial fluid reserve and 70-80 per cent of its composition is distilled water, it can be stated that the tribotest system mimics the natural working conditions of an actual knee joint adequately.

Research limitations/implications
Time and limited availability of the animal-driven samples led to a focus on certain parameters mentioned in the approach. A planned scan of parameter matrix, such as variation of load and speed, would allow deeper knowledge on the lubrication regimes.

Practical implications
Study of relevant tribological contact in human joints might give ideas on new designs for artificial joints.

Social implications
Understanding of lubrication regimes is crucial not only for the treatment of diseases like osteoarthritis but also for the development of new implants to adapt motion of related joint.

Originality/value
Exclusion of water and application as the primary lubricant in the test system brings a new perspective to joint lubrication.
The ecomuseum and solidarity tourism: a case study from northeast Turkey
Authors: Doğan Mustafa 
Published: September 2019

PurposeThe purpose of this paper is to examine the relationship between the ecomuseum and solidarity tourism and to measure their impact on community development.Design/methodology/approachThe study presented here adopts two methods for collecting qualitative data: in-depth interviews and observations. The total number of village households was 42 and the number of households that hosted tourists in their home was 20. Due to the exploratory nature of this study, qualitative methods were employed in the form of lengthy interviews with 13 residents.FindingsThe findings indicate that tourism for the Bogatepe Village ecomuseum has focused on a solidarity perspective which has provided significant benefits to the community ensuring local sustainable development. The ecomuseum as a concept and a destination has helped to control tourism and strengthened the impact of solidarity tourism on the local community.Research limitations/implicationsThe research presented here must be seen as exploratory. More generally, further research is needed to look at the possibility of developing this type of tourism in other rural areas and similar regions of Turkey (covering both small and large areas) with an important cultural heritage.Originality/valueThe combination of the ecomuseum and solidarity tourism can provide a sustainable solution for tourism in rural areas and provide a model in the development of tourism to other villages in Turkey. The question is whether it could also be used in larger rural areas. The study underlines that Bogatepe is certainly worthy of future study.
How do complementarity and discount choices interact with latitude of price acceptance in price bundling?
Authors: Saini Gordhan K. , Sahay Arvind , Kalyanaram Gurumurthy 
Published: September 2019

Purpose
This paper aims to examine three important questions: What would be the effects of pricing at the lower end of a wide vs narrow latitude of price acceptance (LPA) on consumer choice of the bundle? How would the nature of a bundle frame (i.e. discount on bundle vs discount on components) and discount frame (i.e. discount as absolute off vs discount as percentage off) influence the preference given to a price level that is at the wide or narrow end of the LPA? Would the effect be significantly different if the bundle components were complementary vs if they were non-complementary?

Design/methodology/approach
The authors carried out two studies using between-subject experimental design. In Study 1, the authors used 2 (LPA: wide/narrow) × 2 (complementarity: yes/no) × 2 (bundle frame: together/separate) design, and in Study 2, the authors replaced bundle frame with discount frame (i.e. absolute off/percentage off).

Findings
The authors find that the LPA effect is likely to outweigh the complementarity effect; however, a combined effect of complementarity and bundle frame is stronger than the LPA effect. Also, for a wide (narrow) LPA product bundle, absolute off (percentage off) discount frame is more attractive.

Practical implications
Managers should use bundling strategy with complementary products having wider LPA. In case of wide LPA and complementary products, both together and separate frame could be the best bundling strategy while in case of narrow LPA and complementary products, together frame could be the best bundling strategy.

Originality/value
The main contribution relates to the role LPA plays in consumer evaluation of a bundle offer and its interaction with complementarity and discount frame. The authors apply the range hypothesis principles (i.e. price-attractiveness judgments are based on a comparison of market prices to the endpoints of a range of evoked prices) in the bundling context and extend the earlier work in the area of complementarity and discount frame.
Hybrid approach for solving the integrated planning and scheduling production problem
Authors: Ibn Majdoub Hassani Zineb , El Barkany Abdellah , Jabri Abdelouahhab , El Abbassi Ikram , Darcherif Abdel Moumen 
Published: September 2019

PurposeThis paper aims to present a new model for solving the integrated production planning and scheduling. Usually, the two decision levels are treated sequentially because of their complexity. Scheduling depends on the lot sizes calculated at the tactical level and ignoring scheduling constraints generates unrealistic and inconsistent decisions. Therefore, integrating more detail scheduling constraint in production planning is important for managing efficiently operations. Therefore, an integrated model was developed, and two evolutionary optimization approaches were suggested for solving it, namely, genetic algorithm (GA) and the hybridization of simulated annealing (SA) with GA HSAGA. The proposed algorithms have some parameters that must be adjusted using Taguchi method. Therefore, to evaluate the proposed algorithm, the authors compared the results given by GA and the hybridization. The SA-based local search is embedded into a GA search mechanism to move the GA away from being closed within local optima. The analysis shows that the combination of simulated annealing with GA gives better solutions and minimizes the total production costs.Design/methodology/approachThe paper opted for an approached resolution method particularly GA and simulated annealing. The study represents a comparison between the results found using GA and the hybridization of simulated annealing and GA. A total of 45 instances were studied to evaluate job-shop problems of different sizes.FindingsThe results illustrate that for 36 instances of 45, the hybridization of simulated annealing and GA HSAGA has provided best production costs. The efficiency demonstrated by HSAGA approach is related to the combination between the exploration ability of GA and the capacity to escape local optimum of simulated annealing.Originality/valueThis study provides a new resolution approach to the integration of planning and scheduling while considering a new operational constrain. The model suggested aims to control the available capacity of the resources and guaranties that the resources to be consumed do not exceed the real availability to avoid the blocking that results from the unavailability of resources. Furthermore, to solve the MILP model, a GA is proposed and then it is combined to simulated annealing.
Interorganizational cooperation and process innovation
Authors: Pereira Rafael Morais , Borini Felipe Mendes , Oliveira Jr Moacir de Miranda 
Published: September 2019

Purpose
In this paper, the authors investigate whether the location of interorganizational partners affects the outcomes of process innovation. Herein, the term partner location refers to multiple degrees of proximity or distance, including in the same national province or state, in other national provinces or states, in the same country and in foreign countries. The purpose of this paper is to show that partner location, whether domestic or foreign, depends on which partner an organization needs in order to advance its process innovation.

Design/methodology/approach
To test the hypotheses, the authors employed a panel data regression model to analyze data from 28 Brazilian business sectors from 2003 to 2014, all collected for PINTEC: The Brazilian Survey of Technological Innovation, representing a total of 107,854 companies.

Findings
The results show that cooperation is significant with both national and foreign partners, even though they bear different effects on the various degrees of innovativeness related to process innovation.

Practical implications
For managerial practice, the results corroborate that the choice of partners has to be strategic and take their location into account. In particular, practices at the domestic level with suppliers and vocational training centers are relevant to increasing innovation at the micro level. At the same time, for higher levels of innovation, managers should prioritize, within the limitations of existing resources, cooperation with universities, competitors and suppliers from abroad, especially in developed countries.

Originality/value
The main academic contribution of the study is the highlighting partner location (i.e. proximate or distant) as relevant to results of process innovation. Nevertheless, the authors determined that this process is heterogeneous, given the function of each partner and taking the different degrees of innovativeness into account.
