Received: 19 April 2019 Abstract Accepted: 30 October 2019 Current fast development requires continuous improvement of employees’ skills and knowledge. Therefore, companies are looking for the best way for improving the employees’ qualifications and understanding of new concepts and tools which have to be implemented in manufacturing areas. One method employs gamification for this purpose. The aim of this paper is to present how gamification can increase the acquisition of knowledge concerning lean manufacturing concept implementation. Gamification is an active learning approach for people who will understand the subject easier by ‘feeling’ and ‘touching’ personally the analysed problems. The research utilized a questionnaire which assessed the game participants’ engagement level. The assessment focused specifically on the participants’ motivation, cognitive processing and social aspects. The participants were also examined before and after the game in order to assess the increase of their understanding of different lean manufacturing topics and tools. Five different games with different groups of participants were played. The results confirmed the hypothesis that gamification has a positive impact on the knowledge acquisition as well as on motivation, cognitive processing and social aspects. Finally, various insights on how to better design, conduct and utilize gamification in the similar technical context are presented.

In the assembly industry, almost all components are outsourced or transferred to other parties, in order to meet the need for supply. This is referred as outsourcing of production. The outsourcing of assembly product components is based on a relationship model between the contractor and the industry. However, there is no relationship or communication pattern between the contractor or supplier and the assembler. Hence, in order to accelerate line production and overcome problems with assembly components, the communication path is shortened by providing a direct communication channel between the assembler and the supplier or contractor, in order to communicate any problems that arise during the assembly process by internal communication within the industry. The purpose of this study is the design and development of a web-based software application electronic data interchange (EDI) that can be used as a tool for communication between the assembler and supplier. The EDI application provides formal communication between the assembly industry and the contractor providing the components or parts needed in the assembly pro- cess. The main purpose of using EDI technology is to help the assembler to communicate the relevant documents to suppliers quickly, accurately and efficiently. The documents to be communicated are in the form of reports or claims, and are related to non-conformities, errors and component difficulties arising during the assembly process. This research novelty is providing direct communication between assembly and supplier by using EDI application that can give contribution in manufacturing area so it accelerate

Received: 23 March 2019 Abstract Accepted: 11 June 2019 The supply chain of spare parts is the intersection between the supply chain, the after-sales and the maintenance services. Some authors have tried to define improvement paths in terms of models to satisfy the performance criteria. In addition, other authors are directed towards the integration of risk management in the demand forecasting and the stock management (performance evaluation) through probabilistic models. Among these models, the probabilistic graphical models are the most used, for example, Bayesian networks and petri nets. Performance evaluation is done through performance indicators. To measure the appreciation of the supply of the spare parts stock, this paper focuses on the performance evaluation of the system by petri nets. This evaluation will be done through an analytical study. The purpose of this study is to evaluate and analyze the performance of the system by proposed indicators. First, we present a literature review on Petri nets which is the essential tool in our modeling. Secondly, we present in the third section the analytical study of the model based on bath deterministic and stochastic petri networks. Finally, we present an analysis of the proposed model compared to the existing ones.

Received: 11 March 2019 Abstract Accepted: 28 August 2019 Industrial engineers gather knowledge during their bachelor studies through lectures and practical classes. The goal of practical class might be an extension of knowledge and/or a consolidation and application of already gathered knowledge. It is observed that there exists a gap between theory learnt during lectures and practical classes. If practical classes require holistic approach and solving complex tasks (problems), students strive with understanding relations and connections between parts of knowledge. The aim of this article is to show an example of a simple practical assignment that can serve as a bridge between lectures and practical classes through discussion of interactions and relations between parts of theoretical knowledge. It is an example of in-class simulating of a line and cellular layout considering discussion of elements impacting and impacted by the type of layout (e.g. learning curve, changeovers, etc.). In-class verification of the presented approach confirmed its usability for teaching industrial engineers and bridging the gap between theory delivered through lectures and more advanced practical classes.

Received: 25 June 2019 Abstract Accepted: 28 October 2019 Studies linking the use of lean practices to company performance have been increasing as markets are becoming more competitive and companies are eager for reducing waste and therefore implementing the Lean Management (LM) philosophy to improve performance. However, results from these studies have found various and different impacts and some light is needed. Extant literature was reviewed and, to achieve the research objective, a metaanalysis of correlations was carried out. The obtained results suggest a positive relationship between some lean practices and performance measures. Furthermore, the presence of moderators influencing the relationship between lean practices and performance outcomes is highlighted in our results. To our best knowledge, this is the first research that proposes a comparison of results from primary studies on Lean implementation, by analysing the linear relationship between lean practices and enterprise performance. It fills this gap and therefore represents an important contribution.

The objective of this research is to investigate the perception of owner – managers and their employees regarding entrepreneurial leadership. To develop the research, two questions are raised related to the similarities or differences of the perceptions of both groups with what is established in the literature and between the self – evaluation of the owner – managers and their employees on whether the former perform as an entrepreneurial leader. As a research method, both groups are asked to perform, first individual evaluations and then to match certain behaviours and the levels at which they should appear at certain lev- els of entrepreneurial leadership capacity. The data gathered during the investigation were processed using the Categorical Principal Components Analysis and revealed the similari- ties and differences between the perceptions of the owner-managers and their employees on entrepreneurial leadership. In spite of not finding significant differences between what is es- tablished in the literature and among the perceptions of the groups under study, interesting nuances stand out that, if not identified and understood, could have a negative effect on the performance of SMEs. The results of the research demonstrated the importance of the approach of behaviour and perception in the study of entrepreneurial leadership.

Received: 5 March 2019 Abstract Accepted: 14 November 2019 In the two-sided mixed-model assembly line, there is a process of installing two single stations in each position left and right of the assembly line with the combining of the product model. The main aim of this paper is to develop a new mathematical model for the mixed model two-sided assembly line balancing (MTALB) generally occurs in plants producing large-sized high-volume products such as buses or trucks. According to the literature review, authors focus on research gap that indicate in MTALB problem, minimize the length of the line play crucial role in industry space optimization.In this paper, the proposed mathematical model is applied to solve benchmark problems of two-sided mixed-model assembly line balancing problem to maximize the workload on each workstation which tends to increase the compactness in the beginning workstations which also helps to minimize the length of the line. Since the problem is well known as np-hard problem benchmark problem is solved using a branch and bound algorithm on lingo 17.0 solver and based on the computational results, station line effectiveness and efficiency that is obtained by reducing the length of the line in mated stations of the assembly line is increased.
