Simulation Paper Planes a Way to Teach Lean Production 模拟纸飞机是教授精益生产的一种方式
L. A. Salazar, M. P. Revuelta
This article contributes to efforts to teach new methodologies for Industrial Engineering and Engineering Management. Therefore, the creation of the Simulation Paper Planes is presented to teach the principles of Lean Production. The document details the basic rules, general instructions, materials, manufacturing drawings, key performance indicators, and rounds of this simulation. This simulation is a direct and straightforward way to explain and demonstrate the importance of applying the Lean Principles in projects and production processes anywhere in the world. Of the 14 Lean principles, the authors managed to get participants to use 11. As future research, the authors call teachers and consultants to apply this simulation to students (Civil, Industrial, and Construction Engineering) and professionals, to generate a more extensive database. Also, they propose a line of research regarding the level of education in Lean practices between different countries, because, in general terms, undergraduate students in Chile were at the level of graduate students in Colombia.

Managing Sustainability in Electricity Generation 管理发电的可持续性
M. J. B. Kabeyi, O. Olanrewaju
This study looked energy sustainability and sustainable development and measures necessary to ensure that electricity generation is sustainable. Current literature in form of published journal articles and conference proceedings as well as scientific and technical reports on the area of sustainable energy and development was examined. It was noted that there can be no development without energy and there can never be sustainable development without sustainable energy. There is need to sustainably exploit the energy resources to meet current energy needs and those of future generations in an environmentally friendly manner while noting that about 35% of the anthropogenic greenhouse gas emissions come from energy related activities in power generation. Technological advances which include smart grids and decentralization of generation as well as energy carrier technologies are rapidly providing electricity access options available beyond the traditional grid. The study showed that electrification of the global energy mix, electrification of the transport sector, energy efficiency measures and enhanced use of low carbon and renewable energy resources for electricity will play a significant role in the future sustainable energy transition. Additionally to realize energy sustainability effective measures include increased use of solar and wind for grid electricity, use of sustainable energy carriers like hydrogen, development and adoption of energy efficiency measures, limiting environmental impact of energy use including carbon sequestration and enhancing socioeconomic acceptability through community involvement and social acceptability, economic affordability and equity, lifestyles, land use and aesthetics. Whereas renewable energy is a solution to sustainable energy and electricity, current technology and limitation make it necessary to have an optimized mix of renewable and low carbon nonrenewable for sustainable grid electricity.
这项研究着眼于能源可持续性和可持续发展,以及确保发电可持续性的必要措施。审查了以出版的期刊文章和会议记录以及关于可持续能源和发展领域的科学和技术报告的形式发表的现有文献。会议指出,没有能源就没有发展,没有可持续能源就永远不会有可持续发展。我们需要以可持续的方式开发能源,以满足当前和后代的能源需求,同时注意到约35%的人为温室气体排放来自与能源有关的发电活动。包括智能电网和发电分散化以及能源载体技术在内的技术进步正在迅速提供传统电网之外的电力获取选择。研究表明,全球能源结构的电气化、交通部门的电气化、能源效率措施以及加强对低碳和可再生能源的利用将在未来的可持续能源转型中发挥重要作用。此外,实现能源可持续性的有效措施包括增加太阳能和风能在电网中的使用,使用氢等可持续能源载体,开发和采用能源效率措施,限制能源使用对环境的影响,包括碳封存,通过社区参与和社会可接受性提高社会经济可接受性,经济可承受性和公平性,生活方式,土地利用和美学。虽然可再生能源是可持续能源和电力的解决方案,但目前的技术和局限性使得有必要优化可再生能源和低碳不可再生能源的组合,以实现可持续电网电力。

User Aggregation Models for a Video-on-Demand (VoD) System 视频点播(VoD)系统的用户聚合模型
Subrato Mondal, Goutam Sen
We consider the scalability issues in the static data segment location problem in information networks and provide integer linear programming (ILP) formulations for user aggregation. We explore three approaches based on k-means clustering, locality-of-reference and biased locality of reference. The second and third approaches are innovatively modeled as discrete optimization problems. The models are tested in IBM ILOG CPLEX Optimization Studio platform and the computational results are discussed in this paper.

Development of a Lean Manufacturing and SLP-based System for a Footwear Company 某鞋业公司精益生产与slp系统的开发
Victor Paucar, Sergio Munive, V. Núñez, E. Marcelo, J. Alvarez, S. Nallusamy
This research article addresses one of the main problems in the footwear industry, namely the high order non-fulfillment rate. The case study suggests that the main causes of this problem are the increasing rate of defective goods, delays in the production process, and excessive time consumption in the movement of staff and materials. To face this issue, a proposal focused on the use of Lean Manufacturing, such as Systematic Design Planning (SLP) and Andon, is developed to increase productivity, as well as optimize and streamline production processes, considering Covid-19-related safety protocols.To validate the effectiveness of the proposal, an ARENA simulation system was used to establish a new scenario where the defective product indicator decreases by 3.13% and productivity improves by about 38%. In turn, the resulting increase in the number of orders enhances company sales and profits, as well as the ability to meet the customer demand in a timely manner.
本文研究了鞋类行业的主要问题之一,即高订单不履约率。案例研究表明,造成这一问题的主要原因是次品率的增加、生产过程的延误以及人员和材料移动的过多时间消耗。为了应对这一问题,考虑到与covid -19相关的安全协议,制定了一项侧重于使用系统设计计划(SLP)和Andon等精益制造的提案,以提高生产率,并优化和简化生产流程。为了验证该方案的有效性,利用ARENA仿真系统建立了一个新的场景,次品指标降低了3.13%,生产率提高了约38%。反过来,订单数量的增加提高了公司的销售额和利润,以及及时满足客户需求的能力。

Shijin Wang, Ting Hu
With the rapid increase of vehicles in China, traffic jams and parking problem have been becoming the major concern of the urban cities. A large number of studies have shown that parking fees, as economic leverage, can play a vital role in regulating the dynamic traffic demands. This paper proposes a pricing model that applies the principal-agent theory in parking pricing problem. A real-world case of a public parking lot in Shanghai is presented to show the reasonability and applicability of the policy.

Small Series Production and Geometric Analysis of Sheet Metal Car Body Parts Using Forming Tools Made of Fused Filament Fabricated PLA 用熔融长丝制备聚乳酸成形工具进行汽车车身钣金件的小批量生产及几何分析
G. Schuh, G. Bergweiler, F. Fiedler, Philipp Bickendorf, P. Schumacher
The automotive industry is currently facing increased pressure to innovate by developing and producing several drive concepts in parallel. This results in increased demands on product development. Rapid, cost-reduced implementation of tool changes during the product development process is becoming a decisive advantage in an increasingly competitive market. Other players are also entering vehicle development, which are digital, dynamic, flexible and close to the customer. The increasing number of small and medium-sized series and the trend towards mass customization are motivating the need for a flexible and cost-efficient production technology for car body parts.One solution to these challenges is the application of polymer-additive manufactured functional elements in forming tools for thin sheet metal. In this paper, the forming of several demonstrators is described. Therefore, thin sheet metals are deep drawn with tools made of PLA. The experiment represents a small series production of an exemplary car body part. This will be validated by optical measurement of the produced car body parts as well as the tool.
目前,汽车行业面临着越来越大的创新压力,需要同时开发和生产多种驱动概念。这导致对产品开发的需求增加。在产品开发过程中,快速、低成本地实施工具变更正在成为竞争日益激烈的市场中的决定性优势。其他参与者也在进入汽车开发领域,这些领域是数字化的、动态的、灵活的、贴近客户的。随着中小批量生产数量的不断增加和大规模定制化趋势的发展,对灵活、经济的车身零部件生产技术提出了更高的要求。解决这些挑战的一种方法是在薄板金属成形工具中应用聚合物添加剂制造的功能元件。本文描述了几种示威者的形成。因此,薄板金属是用PLA制成的工具深拉。该实验代表了一个示范汽车车身零件的小批量生产。这将通过对生产的车身部件和工具的光学测量来验证。

Data Quality Issues When Quantifying Costs of Complexity 量化复杂性成本时的数据质量问题
A. Staskiewicz, L. Hvam, Anders Haug
Increased demand for product and service variety has meant that many manufacturing companies face problems of increasing product and process complexity. Literature on complexity management provides means for reducing product and process complexity based on quantifying product complexity costs, but when determining product complexity cost, little attention is paid to data quality challenges. The purpose of this paper is to expand the literature on quantifying product complexity costs by clarifying the role of data quality. This is done based on a case study at a world-leading healthcare product manufacturer, where reducing product complexity was investigated. The case study showed that poor data quality resulted in extra use of resources for finding the needed data and implied that the scope of the project had to be significantly reduced. On this basis, this paper argues that methods for reducing product complexity need to incorporate data quality perspectives more.
对产品和服务多样性的需求增加意味着许多制造公司面临产品和工艺复杂性增加的问题。复杂性管理方面的文献在量化产品复杂性成本的基础上提供了降低产品和过程复杂性的方法,但在确定产品复杂性成本时,很少关注数据质量挑战。本文的目的是通过阐明数据质量的作用来扩展量化产品复杂性成本的文献。本文以一家世界领先的医疗保健产品制造商的案例研究为基础,对降低产品复杂性进行了研究。案例研究表明,数据质量差导致在寻找所需数据时额外使用资源,这意味着必须大大缩小项目的范围。在此基础上,本文认为降低产品复杂性的方法需要更多地纳入数据质量视角。

N. Gao, Yuting Li, Yuxi Mai, Haoxuan Xu
Starting from the hotspots of solid waste recycling and reuse, and considering the characteristics of waste transportation in eco-industrial symbiotic network, this paper takes the transportation and distribution process of waste and by-product recycling and reuse in upstream and downstream enterprise clusters as the research object. Different from the traditional transportation research which a single goal-oriented and multi-product independent, Considering model the economic cost performance and environmental performance, as well as the "transport price correlation" between various wastes, this paper constructs a multi-objective transport planning model of Interacted multi-product. Finally, on the basis of the multi-product and multi-objective model, the paper refers to the related method theory of the second generation fast non-dominated sorting genetic algorithm (NSGA-II) which based on the elite selection strategy. By carrying out calculation and result analysis on the basis of algorithm implementation, the paper verifies the effectiveness of the model and algorithm.

Developing Knowledge Management System for Supporting Learning Activity in the Ceramics Craft Education 陶瓷工艺教育中支持学习活动的知识管理系统的开发
Tzu-Yun Hsu, Hsien-Jung Wu
Traditional craft education greatly relies on teacher-student relationship that transmits knowledge of skills and processes through demonstration. This way of distributing craft knowledge decreases the learning effectiveness for lack of methodical knowledge retrieval and sharing approach. This paper presents a knowledge management system that transfers tacit knowledge of the craft practitioner in collaboration with the teacher’s pedagogy in the craft education. Initially, a protocol analysis is used to capture the tacit knowledge from the external expert of craft practitioner and paired with the teacher’s pre-class preparation stored in the current teaching archive. Focused on the procedural type of knowledge, the proposed knowledge management system is examined in a ceramics craft course offered in the author’s department. This paper illustrates the picture of linking KM system with craft teaching scenario. Through the aid of multimedia learning environment, students show encouraging progress in their creative works based on the support of the knowledge management system.
传统的工艺教育很大程度上依赖于师生关系,通过示范传递技能和工艺知识。这种分配工艺知识的方式由于缺乏系统的知识检索和共享方法而降低了学习效率。本文提出了一种在工艺教育中,结合教师的教学方法,实现工艺实践者隐性知识转移的知识管理系统。首先,使用协议分析从外部专家或工艺实践者那里获取隐性知识,并与当前教学档案中存储的教师课前准备相匹配。本文以本系陶瓷工艺课程为例,对所提出的知识管理系统进行了实证研究。本文描绘了知识管理系统与工艺教学场景相结合的图景。借助多媒体学习环境,学生在知识管理系统的支持下,在创作上取得了令人鼓舞的进步。

Organizational Learning from Failure Can Augment Ambidexterity: Evidence from Japan 组织从失败中学习可以增强两面性:来自日本的证据
S. Nagayoshi, J. Nakamura
It is important for companies to adapt to changes in the business environment to gain or maintain a sustainable competitive advantage. In other words, they need to augment their management base by upgrading their current businesses and finding new business opportunities in line with future corporate growth and life cycles. However, it is difficult to achieve these objectives concurrently. In this study, we present a case of a Japanese company that has grown as a measure of information sharing and organizational learning from failure. We aim to explain how organizational learning from failure has led to ambidexterity, which consists of exploration and exploitation; we also examine whether organizational learning from failure is effective in exploration and exploitation. We used a quantitative approach through surveys and analysis of covariance structure. As a result, we find that organizational learning from failure is more effective for exploitation than for exploration in this company.
公司适应商业环境的变化以获得或保持可持续的竞争优势是很重要的。换句话说,他们需要通过升级现有业务和寻找符合未来企业成长和生命周期的新业务机会来扩大管理基础。然而,很难同时实现这些目标。在这项研究中,我们提出了一个日本公司的案例,该公司已经成长为信息共享和组织从失败中学习的衡量标准。我们的目标是解释组织从失败中学习如何导致双灵巧性,其中包括探索和利用;我们还研究了组织从失败中学习在探索和利用中是否有效。我们通过调查和协方差结构分析采用了定量方法。因此,我们发现在这家公司中,组织从失败中学习对开发比探索更有效。
