This article intends to justify the gap in the research of similarity coefficient driven approach- es and cell formation problems (CFP) based on ratio data in cellular manufacturing systems (CMS). The actual implication of ratio data was vaguely addressed in past literature, which has been corrected recently. This research considered that newly projected CFP based on ration data. This study further revealed the lack of interest of researchers in investigation for an appropriate and improved similarity coefficient primarily for CFP based on ratio data. For that matter a novel similarity coefficient named as Generalized Utilization-based Simi- larity Coefficient (GUSC) is introduced, which scientifically handles ratio data. Thereafter a two-stage cell formation technique is adopted. First, the proposed GUSC based method is employed to obtained efficient machine cells. Second, a novel part allocating heuristic is proposed to obtain effective part families. This proposed approach is successfully verified on the test problems and compared with algorithms based on another similarity coefficient and a recent metaheuristic. The proposed method is shown to obtain 66.67% improved solutions.
本文旨在弥补在元胞制造系统(CMS)中基于比率数据的相似系数驱动方法- es和细胞形成问题(CFP)研究中的空白。在过去的文献中,比率数据的实际含义是模糊的,最近得到了纠正。本研究考虑了基于定量数据的新预测CFP。本研究进一步揭示了研究人员对主要基于比率数据的CFP的适当和改进的相似系数缺乏兴趣。为此,提出了一种新的相似系数——基于广义利用的相似系数(GUSC),它能科学地处理比率数据。然后采用两阶段细胞形成技术。首先,采用基于GUSC的方法获得有效的机器单元。其次,提出了一种新的零件分配启发式算法来获取有效零件族。该方法成功地在测试问题上进行了验证,并与基于另一个相似系数和最近的元启发式算法的算法进行了比较。结果表明,本文提出的方法可获得66.67%的改进解。

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.

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.
随着市场竞争日益激烈,公司渴望减少浪费,因此实施精益管理(LM)理念以提高绩效,将精益实践与公司绩效联系起来的研究越来越多。然而,这些研究的结果发现了各种不同的影响,需要一些启示。对现有文献进行了回顾,并对相关性进行了荟萃分析,以实现研究目标。所得结果表明,一些精益实践和绩效指标之间存在正相关关系。此外,在我们的结果中强调了影响精益实践与绩效结果之间关系的调节因子的存在。据我们所知,这是第一个通过分析精益实践与企业绩效之间的线性关系,对精益实施的主要研究结果进行比较的研究。它填补了这一空白,因此是一项重要贡献。

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.
接收日期:2019年8月28日工业工程师在本科学习期间通过讲座和实践课程收集知识。实践课的目标可能是扩展知识和/或巩固和应用已经收集到的知识。人们注意到,在课堂上学到的理论和实践课之间存在着差距。如果实践课程要求整体方法和解决复杂的任务(问题),学生努力理解知识各部分之间的关系和联系。本文的目的是展示一个简单的实践作业的例子,通过讨论理论知识各部分之间的相互作用和关系,它可以作为讲座和实践课程之间的桥梁。这是考虑到影响布局类型的元素(例如学习曲线,转换等)的讨论的线和细胞布局的课堂模拟的一个例子。课堂上对所提出的方法的验证证实了它对工业工程师教学的可用性,并弥合了通过讲座传授的理论与更高级的实践课程之间的差距。

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.
在双面混合装配线中,结合产品型号,在装配线的左右各位置安装两个单工位。本文的主要目的是建立一个新的数学模型,用于混合模型双边装配线平衡(MTALB)通常发生在生产大型大批量产品的工厂,如公共汽车或卡车。根据文献综述,作者对研究差距的关注表明,在MTALB问题中,最小化线路长度对产业空间优化起着至关重要的作用。本文将所提出的数学模型应用于解决双边混合模型装配线平衡问题的基准问题,以最大限度地提高每台工作站的工作量,从而增加初始工作站的紧凑性,并有助于最小化生产线长度。由于该问题是众所周知的np-hard问题,在lingo 17.0求解器上使用分支定界算法求解基准问题,根据计算结果,通过减少装配线的配合工位的线长来提高工位线的有效性和效率。
