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.","PeriodicalId":49493,"journal":{"name":"South African Journal of Industrial Engineering","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135002311","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}

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.","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":"49248057","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}

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.","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":"44563332","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}

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.","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":"42100861","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}

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.","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":"44155508","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}

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.","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":"44814556","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}
