Cyber-physical production systems (CPPS) represent a relevant aspect related to industry 4.0 and the advances promoted by the digitization and use of artificial intelligence in the production environment in the search for the development of smart factories. This study aims to assess the maturity level of cyber-physical production system (CPPS) within manufacturing industries in the Amazon. The research uses a quali-quantitative approach to analyze the problem by conducting exploratory case studies (indepth case) and the research framework used aimed to evaluate and measure the CPPS within three manufacturing industries in the Amazon (n = 3) to measure their maturity. Findings reveal a positive relationship between the type of production system adopted by the company, the level of automation, and the maturity of the CPPS. The proposed methodology can assist other companies in the development of the technological strategy, supporting the digital transformation process in order to obtain competitive advantage. The study contributes by addressing the topic of cyber-physical production systems from the point of view of operations management and strategy.

Industrial Engineering, through its role as design, planning and organizational body of the industrial production, has been crucial for the success of manufacturing companies for decades. The potential, expected over the course of Industry 4.0 and through the application of Data Analytic tools and methods, requires a coupling to established methods. This creates the necessity to extend the traditional job description of Industrial Engineering by new tools from the field of Data Analytics, namely Industrial Data Science. Originating from the historic pioneers of Industrial Engineering, it is evident that the basic principles will remain valuable. However, further development in view of the data analytic possibilities is already taking place. This paper reviews the origins of Industrial Engineering with reference to four pioneers, draws a connection to current day usage, and considers possibilities for future applications of Industrial Data Science.
工业工程作为工业生产的设计、规划和组织机构,几十年来一直是制造企业成功的关键。在工业4.0的过程中,通过数据分析工具和方法的应用,预期的潜力需要与既定方法相结合。这就需要通过数据分析领域的新工具,即工业数据科学,来扩展工业工程的传统工作描述。起源于工业工程的历史先驱,很明显,基本原则将仍然有价值。但是,鉴于数据分析的可能性,已经在进行进一步的发展。本文回顾了工业工程的起源,参考了四位先驱者,将其与当前的使用联系起来,并考虑了工业数据科学未来应用的可能性。

Many important problems in engineering management can be formulated as Resource Assignment Problem (RAP). The Workers Assignment Problem (WAP) is considered as a sub-class of RAP which aims to find an optimal assignment of workers to a number of tasks in order to optimize certain objectives. WAP is an NP-hard combinatorial optimization problem. Due to its importance, several algorithms have been developed to solve it. In this paper, it is considered that a manager is required to provide a training course to his workers in order to improve their level of skill or experience to have a sustainable competitive advantage in the industry. The training cost of each worker to perform a particular job is different. The WAP is to find the best assignment of workers to training courses such that the total training cost is minimized. Two metaheuristic optimizations named Whale Optimization Algorithm (WOA) and Flower Pollination Algorithm (FPA) are utilized to final the optimal solution that reduces the total cost. MATLAB Software is used to perform the simulation of the two proposed methods into WAP. The computational results for a set of randomly generated problems of various sizes show that the FPA is able to find good quality solutions.
工程管理中的许多重要问题可以归结为资源分配问题。工人分配问题(WAP)被认为是RAP的一个子类,旨在找到工人对多个任务的最优分配,以优化某些目标。WAP是一个NP难的组合优化问题。由于其重要性,已经开发了几种算法来解决它。在本文中,管理者需要为其员工提供培训课程,以提高他们的技能或经验水平,从而在行业中具有可持续的竞争优势。每个工人执行特定工作的培训成本是不同的。WAP旨在为员工找到培训课程的最佳分配,从而将总培训成本降至最低。利用Whale Optimization Algorithm(WOA)和Flower Pollination Algorithms(FPA)两种元启发式优化算法来最终获得降低总成本的最优解。利用MATLAB软件对所提出的两种方法进行WAP仿真。对一组不同大小的随机生成问题的计算结果表明,FPA能够找到高质量的解。

Understanding the scientific and social structure of a discipline is a fundamental aspect for scientific evaluation processes, identifying trends and niches, and balancing the trade-off between exploitation and exploration in research. In the present contribution, the production of doctoral theses is used as a proxy to analyze the scientific structure of the knowledge area of business organization in Spain. To that end, a complex networks approach is selected, and two different networks are built: (i) the social network of co-participation in thesis examining committees and thesis supervision, and (ii) a bipartite network of theses and thesis descriptors. The former has a modular structure that is partially explained by thematic specialization in different subdisciplines. The latter serves to assess the interdisciplinary structure of the discipline, as it enables the characterization of affinity levels between fields, research poles and thematic clusters. Our results have implications for the scientific evaluation and formal definition of related fields.
了解一个学科的科学和社会结构是科学评估过程、确定趋势和利基以及平衡研究中开发和探索之间权衡的一个基本方面。在本论文中,博士论文的产生被用作分析西班牙商业组织知识领域科学结构的代理。为此,选择了一种复杂的网络方法,并建立了两个不同的网络:(i)共同参与论文审查委员会和论文监督的社会网络,以及(ii)论文和论文描述符的二分网络。前者具有模块化结构,不同子学科的专题专业化部分解释了这一结构。后者用于评估学科的跨学科结构,因为它能够表征领域、研究极和专题集群之间的亲和力水平。我们的研究结果对相关领域的科学评估和正式定义具有启示意义。

The adoption of lean manufacturing (LM) in small and medium-sized enterprises (SMEs) is not as vigorous as in large organizations. This purpose of this study is to assess the maturity level of LM implementation in the machinery and equipment (ME) SMEs. The close-ended survey questionnaire method was adopted in three Malaysian manufacturing ME SMEs, and data was collected for the descriptive analysis. The findings showed that these case companies are generally at a low-to-moderate level in terms of LM understanding. Meanwhile, the extent of LM implementation and the success level is still moderate. The proposed LM conceptual model provides valuable perspectives and establishes a holistic understanding of the phenomena in LM maturity status for ME SMEs. The proper synchronization of LM understanding, implementation, and success are vital to building the strong LM maturity foundation for lean organizational transformation. It serves as useful guidance and strategic framework to other companies in dealing with the operational excellence challenges. The significance of this study will help ME SMEs to identify their current position and promote progress in the lean application journey. This will benefit the management team and lean practitioners in decision-making and enhance tactics to attain a higher level of success.
在中小企业(SMEs)中采用精益制造(LM)并不像在大型组织中那样积极。本研究的目的是评估机械设备(ME)中小企业实施LM的成熟度。采用封闭式调查问卷法对马来西亚三家制造业中小微企业进行调查,收集数据进行描述性分析。研究结果表明,这些案例公司在LM理解方面普遍处于中低水平。同时,LM的实施程度和成功程度仍然是中等的。本文提出的LM概念模型提供了有价值的视角,并建立了对中小微企业LM成熟状态现象的整体理解。LM的理解、实施和成功的适当同步对于为精益组织转型建立强大的LM成熟度基础至关重要。它为其他公司应对卓越运营挑战提供了有用的指导和战略框架。本研究的意义将有助于中小微企业认清自身的现状,推动精益应用之旅的进展。这将有利于管理团队和精益实践者在决策和提高战术,以达到更高的成功水平。

This study aims to analyze the failure factors of PT. XYZ in 2018 – 2020 in terms of time, cost, labor, Health, Safety, and Environment (HSE), and quality based on the Success Project Factor (SPF). It includes 183 projects with the Non-Probability Sampling technique. The researcher uses fishbone and Pareto to identify problems. The results showed Schedule Performance Index (SPI)  1 indicated the project is in the late category, the Cost Performance Index (CPI)  1 indicated cost overrun, Safety Performance Index (SFPI)  0 indicated the K3 target could not be reached, the Client Satisfaction Index (CSI) = 34.03, indicated that it is in the dissatisfied category, then Productivity Coefficient Plan Realization, it meant the workforce was less productive. After the analysis of fishbone and Pareto, the data show that the highest cause was 13% due to lack of supervision, project cost aspects were 13% due to delays, HSE project aspect were 13% due to no K3 process before work begins, the quality aspect was 17% due to no training, and the labor aspect was 17% due to poor worker discipline.
本研究旨在基于成功项目因素(SPF),从时间、成本、劳动力、健康、安全与环境(HSE)和质量方面分析PT.XXYZ在2018-2020年的失败因素。它包括183个采用非概率抽样技术的项目。研究人员使用鱼骨和帕累托来识别问题。结果显示,进度绩效指数(SPI)  1表示该项目属于后期类别,即成本效益指数(CPI)  1指示成本超支,安全性能指数(SFPI)  0表示无法达到K3目标,客户满意度指数(CSI) = 34.03,表明它属于不满意的类别,那么生产力系数计划的实现,意味着劳动力的生产力较低。经过鱼骨和Pareto的分析,数据显示,最高原因是缺乏监督,项目成本方面是由于延误,HSE项目方面是由于开工前没有K3流程,质量方面是由于没有培训,劳动方面是由于工人纪律差,占13%。

The U-shaped assembly lines help to have more flexibility than the straight assembly lines, where the operators can perform tasks in both sides of the line, the entrance and the exit sides. Having more than one operator in any station of the line can reduce the line length and thereby affects the number of produced products. This paper combines the U-shaped assembly line balancing problem with the multi-manned assembly line balancing problem in one problem. In addition, the processing times of the tasks are considered as stochastic, where they are represented as random variables with known means and variances. The problem is formulated as a mixed-integer linear programming and the cycle time constraints are formulated as chance-constraints. The proposed algorithm for solving the problem is a differential evolution algorithm. The parameter of the algorithm is optimized using experimental design and the computational results are done on 71 adapted problems selected from well-known benchmarks.
U形装配线有助于比直线装配线具有更大的灵活性,在直线装配线中,操作员可以在生产线的两侧、入口和出口执行任务。在线路的任何一个站点都有一个以上的操作员可以减少线路长度,从而影响生产产品的数量。本文将U型装配线平衡问题与多人装配线平衡的问题结合为一个问题。此外,任务的处理时间被认为是随机的,其中它们被表示为具有已知均值和方差的随机变量。该问题被公式化为混合整数线性规划,循环时间约束被公式化为由机会约束。所提出的用于解决该问题的算法是差分进化算法。通过实验设计对算法的参数进行了优化,并对从知名基准中选取的71个自适应问题进行了计算。

Integrating Tier-1 module suppliers in car sequencing problem 整合一级模块供应商解决汽车排序问题

The objective of this study is to develop a car assembly sequence that is mutually agreed between car manufacturers and Tier-1 module suppliers such that overall modular supply chain efficiency is improved. In the literature so far, only constraints of car manufacturers have been considered in the car sequencing problem. However, an assembly sequence from car manufacturer imposes a module assembly sequence on Tier-1 module suppliers since their assembly activities are synchronous and in sequence with assembly line of that car manufacturer. An imposed assembly sequence defines a certain demand rate for Tier-1 module suppliers and has significant impacts on operational cost of these suppliers which ultimately affects the overall modular supply chain efficiency. In this paper, a heuristic approach has been introduced to generate a supplier cognizant car sequence which does not only provide better operational conditions for Tier-1 module suppliers, but also satisfies constraints of the car manufacturer.
本研究的目的是开发一个汽车制造商和一级模块供应商之间相互同意的汽车装配序列,从而提高整体模块化供应链的效率。在目前的文献中,在汽车排序问题中只考虑了汽车制造商的约束。然而,来自汽车制造商的装配序列对一级模块供应商施加了模块装配序列,因为它们的装配活动是同步的,并且与该汽车制造商的装配线是顺序的。强加的装配顺序定义了一级模块供应商的一定需求率,并对这些供应商的运营成本产生重大影响,最终影响整个模块化供应链的效率。本文采用启发式方法生成供应商认知汽车序列,该序列不仅为一级模块供应商提供了更好的操作条件,而且满足了汽车制造商的约束。

The philosophy of production without waste is the fundamental belief behind lean manufacturing that should be adopted by enterprises. One of the waste elimination methods is assembly line balancing for lean manufacturing, i.e. Yamazumi. The assembly line balancing is to assign tasks to the workstations by minimizing the number of workstations to the required values. There should be no workstation with the excessively high or low workload, and all workstations must ideally work with balanced workloads. Accordingly, in this study, the axiomatic design method is applied for assembly line balancing in order to achieve maximum output with the installed capacity. In order to achieve this aim, all improvement opportunities are defined and utilized as an output of the study. Computational results indicate that the proposed method is effective to reduce operators’ idle time by 12%, imbalance workload between workstations by 38%, and the total number of workers by 12%. As a result of these improvements, the production volume is increased by 23%.
生产不浪费的哲学是企业应该采用的精益制造背后的基本信念。消除浪费的方法之一是精益制造的装配线平衡,即Yamazumi。装配线平衡是通过将工作站数量最小化到所需值来将任务分配给工作站。并没有工作负载过高或过低的工作站,所有工作站都必须在理想的工作负载平衡的情况下工作。因此,在本研究中,公理化设计方法被应用于装配线平衡,以在装机容量的情况下实现最大产量。为了实现这一目标,所有的改进机会都被定义并用作研究的输出。计算结果表明,该方法有效地减少了12%的操作员空闲时间、38%的工作站间不平衡工作量和12%的工人总数。由于这些改进,产量增加了23%。

Performance measurement in Judo usually focuses on some KPIs whose values indicate the final performance of the athlete. This paper deals with firstly identifying which these main KPIs in Judo are. Once this is done, the KPIs are classified into four different clusters: Physical training, specific training, Psychology and Lifestyle. Then, it proposes the multi-criteria decision aim technique of Analytic Network Process as the most indicate one to link not only the impact of the Judo KPIs with the achievement of the judoka’s strategic objectives but also to identify both the relative and the global importance of each of these KPIs. 
柔道的成绩衡量通常侧重于一些kpi,这些kpi的值表明运动员的最终表现。本文首先讨论了柔道中这些主要kpi是什么。一旦这样做了,kpi被分为四个不同的组:体育训练,特殊训练,心理和生活方式。然后,提出了分析网络过程的多准则决策目标技术,作为最具指示性的技术,不仅将柔道kpi的影响与柔道战略目标的实现联系起来,而且还确定了每个kpi的相对重要性和全局重要性。
