This study aimed to discuss the factors in shaping organisational culture when an organisation promotes lean management. It also aimed to explore which factors are critical among these factors. This study applied a survey questionnaire methodology, and obtained the consent of ten experts and scholars through purposive sampling. The survey was implemented by respondents completing the questionnaires themselves or through telephone interviews. The data were analysed by applying a decision-making trial and evaluation laboratory to understand the degree of causality and correlation between the criteria. According to the data analysis results, three dimensions – ‘Lean management has substantial benefits‘, ‘Prevent process waste‘, and ‘Implement lean management programmes and activities/methods and tools’ – had the highest degree of correlation; and three dimensions – ‘Lean management has substantial benefits‘, ‘Base your management decisions on a long-term philosophy‘, and ‘Prevent process waste’ – had the highest degree of causality. Together these dimensions formed the group of causes. However, the degree of causality of ‘Lean management has substantial benefits’ was far greater than that of the other dimensions. This indicated its significance and influence. The degree of causality of ‘Implement lean management programmes and activities/methods’ was far less than that of the other dimensions, indicating that this dimension was the effect and was influenced by the other five dimensions. Overall, ‘Lean management has substantial benefits’ was the most critical factor with the highest degree of causality and correlation. Regarding management implications, a business organisation must encourage its members to regard this dimension as the most critical element when it promotes and shapes the organisational culture of lean management.
本研究的目的是讨论在塑造组织文化的因素,当一个组织促进精益管理。它还旨在探讨这些因素中哪些因素是关键的。本研究采用调查问卷法,通过有目的抽样,获得10位专家学者的同意。该调查是通过受访者自己填写问卷或通过电话采访来实施的。通过应用决策试验和评估实验室来分析数据,以了解标准之间的因果关系和相关性的程度。根据数据分析结果,三个维度-“精益管理具有实质性利益”,“防止过程浪费”和“实施精益管理计划和活动/方法和工具”-具有最高的相关性;而三个维度——“精益管理有实质性的好处”、“基于长期理念的管理决策”和“防止过程浪费”——具有最高程度的因果关系。这些维度合在一起构成了原因组。然而,“精益管理具有实质性利益”的因果关系程度远远大于其他维度。这表明了它的重要性和影响。“实施精益管理方案和活动/方法”的因果关系程度远低于其他维度,表明该维度是其他五个维度的影响和影响。总体而言,“精益管理具有实质性利益”是最关键的因素,具有最高程度的因果关系和相关性。关于管理的含义,一个商业组织在促进和塑造精益管理的组织文化时,必须鼓励其成员将这一维度视为最关键的因素。

The purpose of higher learning is to equip students with the necessary skills and knowledge to support their respective professional careers. Ultimately, each career follows the employment or entrepreneurship path. The higher learning curriculum is generally more structured for the employment path, even though the global economy of the 21 century is fast becoming largely entrepreneurial. This work investigates the scope of entrepreneurship in the context of industrial engineering graduates. The aim is to develop a method to determine quantitatively the importance of focusing on entrepreneurial competence development in engineering students, and to propose a strategy to address the evident need for a greater emphasis on entrepreneurial competencies in graduate industrial engineers, based on market data. The approach is to analyse entrepreneurial projects as advertised by on-line freelance platforms, to determine the general characteristic skill-level requirements and perspectives on opportunity and remuneration. A strategy to enhance graduate entrepreneurial competency is also presented.
高等教育的目的是为学生提供必要的技能和知识,以支持他们各自的职业生涯。最终,每个职业都遵循就业或创业的道路。尽管21世纪的全球经济正在迅速成为企业家,但高等教育课程通常更适合就业道路。这项工作调查了工业工程毕业生创业的范围。其目的是开发一种方法,以定量确定重视工程专业学生创业能力发展的重要性,并根据市场数据提出一项战略,以解决研究生工业工程师更加重视创业能力的明显需求。该方法是分析在线自由职业者平台宣传的创业项目,以确定一般特征技能水平要求以及对机会和薪酬的看法。同时提出了提高研究生创业能力的策略。

In terms of project risk management, ‘systemic risk’ is identified as risks which are artefacts of the environment which a project is executed in, and are related to (i) the project team’s actions, (ii) how project controls are managed and interact, and (iii) how the project is planned and executed. This paper proposes a methodology to estimate the cost impact of systemic risk on a portfolio of projects by using risk quantification and Monte Carlo simulation, in the absence of a validated parametric risk model, to estimate the systemic risks in an entire portfolio of projects. The case study simulation results indicate a significant effect of systemic risks on the project portfolio risk profile, where systemic risks increased the P80 value of the contingency requirement by +85.6%. The successful management of systemic risk would contribute to project success by limiting unnecessary waste.
就项目风险管理而言,“系统性风险”被确定为项目执行环境中的人为因素,与(i)项目团队的行动、(ii)项目控制的管理和互动方式以及(iii)项目的规划和执行方式有关。本文提出了一种方法来估计系统性风险对项目组合的成本影响,方法是在没有经过验证的参数风险模型的情况下,使用风险量化和蒙特卡洛模拟来估计整个项目组合中的系统性风险。案例研究模拟结果表明,系统性风险对项目组合风险状况有显著影响,其中系统性风险使应急需求的P80值增加了+85.6%。系统性风险的成功管理将通过限制不必要的浪费来促进项目的成功。

Mixed reality as an emerging technology can improve users’ experience. Using this technology, people can interact between virtual objects and the real world. Mixed reality has enormous potential for enhancing the human cyber—physical system for different manufacturing functions: planning, designing, production, monitoring, quality control, training, and maintenance. This study aims to understand the existing development of mixed reality technology in manufacturing by analysing patent publications from the InnovationQ-Plus database. Evaluations of trends in this developing technology have focused on qualitative literature reviews and insufficiently on patent technology analytics. Patents connected to mixed reality will be mapped to give technology experts a better grasp of present progress and insights for future technological development in the industry. Thus 709 patent publications

The knowledge transfer role of a project management office in a matrixstructured telecommunication organisation was investigated by means of focus groups and interviews, and the results were analysed with ATLAS.ti software. The results confirmed the key role that the project management office plays in knowledge transfer. Corporate culture was found to have a greater effect on knowledge transfer than the type of organisational structure. Conflicts and other challenges typical of matrix structures did not necessarily hinder knowledge transfer, and even contributed to it. The knowledge transfer roles of the project management office were primarily perceived as a moderator of the transfer of technical information and a mediator of project and business knowledge.
通过焦点小组和访谈的方式调查了矩阵结构电信组织中项目管理办公室的知识转移作用,并用ATLAS.ti软件对结果进行了分析。研究结果证实了项目管理办公室在知识转移中发挥的关键作用。研究发现,与组织结构类型相比,企业文化对知识转移的影响更大。矩阵结构典型的冲突和其他挑战并不一定会阻碍知识转让,甚至会助长知识转让。项目管理办公室的知识转让作用主要被视为技术信息转让的调节者和项目和商业知识的调解人。

Improving a robot’s posture enables it to perform with greater accuracy and repeatability. A stiffer posture also protects the robot from unnecessary vibrations and deflections that may be induced by an applied load. This paper presents a method for choosing high stiffness robot postures. The method is demonstrated on a six-degree-of-freedom Fanuc M10-iA serial manipulator. The posture identification and stiffness modelling were achieved by a reliable and cost-effective alternative to deflection measurement using IEPE accelerometers.

WELDING OF ADDITIVE MANUFACTURED ALSI10MG: USING LASER WELDING IN A VACUUM FOR HIGH QUALITY WELD SEAMS — A NEW APPROACH TO WELDING LPBF MANUFACTURED ALSI10MG 添加剂alsi10mg的焊接:采用真空激光焊接获得高质量焊缝——一种焊接alsi10mg LPBF的新方法

Metal additive manufacturing has evolved to a manufacturing process used in different industries. Especially in highly complex applications with small batches, such as aerospace or tooling, laser powder bed fusion (LPBF) has become established. But one of its major limitations is the size of the build chamber, which is limited to around 800 x 400 x 500 mm for the largest machine that is currently available. One solution to overcome this size limitation is to weld additive manufactured parts. While it has been proven for different materials that conventional welding processes can be applied to LPBF manufactured parts, the resulting weld seam quality for AlSi10Mg is still insufficient. By using laser welding in a vacuum, which is a newly developed and highly efficient laser welding process, the quality of the weld seams, especially in terms of porosity, can be improved. This technology is used to produce weld seams that are then tested for their mechanical properties. Finally, a solution for combining LPBF parts with conventional aluminium alloys is presented.
金属增材制造已经发展成为一种应用于不同行业的制造工艺。特别是在小批量的高度复杂的应用中,如航空航天或模具,激光粉末床熔合(LPBF)已经建立起来。但其主要限制之一是构建室的尺寸,对于目前可用的最大机器,其限制在800 x 400 x 500 mm左右。克服这种尺寸限制的一个解决方案是焊接增材制造的零件。虽然传统的焊接工艺已经被证明可以应用于LPBF制造的零件,但AlSi10Mg的焊缝质量仍然不足。真空激光焊接是一种新型的高效激光焊接工艺,可提高焊缝质量,特别是气孔率。该技术用于生产焊缝,然后测试其机械性能。最后,提出了LPBF零件与常规铝合金结合的解决方案。

Delays in project completion by state-owned enterprises are a major concern and a threat to the South African economy. This study investigates both the internal and the external factors influencing the late delivery of projects in state-owned enterprises, with ESKOM as a case study. The research design was a survey questionnaire that was used to gather sufficient information. The study revealed key internal and external factors influencing the late delivery of projects in the state-owned enterprises, including the failure to update construction programmes, the late delivery of contractor-supplied materials, corruption, and political interference. In conclusion, we posit that, to ensure early project completion, the authorisation and empowerment of the project team is vitally important.
国有企业延迟完成项目是一个主要问题,也是对南非经济的威胁。本研究以ESKOM为例,探讨了影响国有企业项目延迟交付的内部和外部因素。研究设计是一份调查问卷,用于收集足够的信息。该研究揭示了影响国有企业项目延迟交付的关键内部和外部因素,包括未能更新施工计划、承包商提供的材料延迟交付、腐败和政治干预。总之,我们认为,为了确保项目早日完成,项目团队的授权和授权至关重要。

In conclusion, we posit that, to ensure early project completion, the authorisation and empowerment of the project team is vitally important.","PeriodicalId":49493,"journal":{"name":"South African Journal of Industrial Engineering","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49382319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Product design in the early stages requires a more quantitative process to ensure that the simulation study's outcome will meet expectations. The purpose of this study was to determine whether a manufacturing simulation software package could effectively evaluate and validate the conceptualised blank and tooling to manufacture a sizeable complex-shaped aluminium alloy aircraft panel using die sheet hydroforming. Blank and tool concepts were conceptualised, evaluated, and validated digitally using the forming process conceptualisation cycle. Without the need to trial several blank and tool concepts physically, a significant saving was achieved using a resource-efficient development process. Even without modelling the hyperelastic rubber elements, a successful die sheet hydroformed simulation result was conducted. However, the study showed that a rubber-to-metal friction coefficient must be incorporated appropriately. The study further showed the lack of standard metrology methods in commercial simulation packages to evaluate a simulation result accurately. Simulation metrology is a new area of interest that requires further development. This research contributes to improving the sheet metal forming simulation process and, specifically, die sheet hydroforming process simulation. The study will benefit the aerospace and automotive industry and promote the adoption of digital manufacturing processes.
早期阶段的产品设计需要一个更加量化的过程,以确保模拟研究的结果符合预期。本研究的目的是确定制造模拟软件包是否能够有效评估和验证概念化坯料和工具,以使用压模板液压成形制造大型复杂形状的铝合金飞机面板。坯料和工具概念通过成形工艺概念化循环进行概念化、评估和数字验证。在不需要对几个空白和工具概念进行物理试验的情况下,使用资源高效的开发过程实现了显著的节约。即使没有对超弹性橡胶元件进行建模,也能成功地进行模片液压成形模拟。然而,研究表明,必须适当地加入橡胶与金属的摩擦系数。该研究进一步表明,商业模拟包中缺乏准确评估模拟结果的标准计量方法。仿真计量学是一个新的感兴趣的领域,需要进一步发展。本研究有助于改进板料成形模拟过程,特别是模具板料液压成形过程模拟。这项研究将有利于航空航天和汽车行业,并促进数字化制造流程的采用。
