From a requirements engineering perspective, a significant question is whether the requirements to use redundant solutions are necessary for space system design when a reliability target has been specified. Does a requirement to use redundancy impose a specific solution with no other effect on need satisfaction? If so, can it be deleted with no adverse effect on mission success? To answer these questions, the impact of different redundancy configurations on mission success are studied, using a space system as a test case. Mission success is modeled as a function that accrues value over the satellite’s operational life. The different redundancy configurations are then compared for different rates of value accumulation over the space system’s operational life, which encompass reasonable value accumulation rates observed in most real-life space missions. The numerical results reveal that when all design alternatives provide the same reliability at end of life at the same cost, systems that employ redundancy have a higher expected value than a system without redundancy.","PeriodicalId":54353,"journal":{"name":"Engineering Management Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45356786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this research seeks to explore AI uses and its benefits on the UK construction industry. Given the new and unexplored nature of the research problem, a qualitative case study research methodology was adopted. Construction projects, which have adopted some of the AI forms all around the UK, are investigated extracting the use of the technology and how processes within the construction industry can benefit from the adoption of AI. Developing an AI system can benefit the construction industry in terms of the planning process, organizations have implemented AI systems to accomplish tasks such as tunnel inspections, safety hazard identifying, and risk management. These implementations have proved to be successful and efficient in improving production within the organizations. This paper highlights the key uses and benefits of AI-based systems within the construction industry. The business model was developed based on current work practices with AI and without AI. It is concluded that the industry as a whole should enhance coordination and cooperation across the value chain and agree on common goals and standards for the adoption of AI.","PeriodicalId":54353,"journal":{"name":"Engineering Management Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47941410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A crucial aspect enabling this integration is to define the scope of the changes, referred to as the system of interest. This can be challenging for engineering managers due to mounting system complexity caused by: an inter-organizational environment, a multitude of diverse stakeholders, the multidomain environment, and an increasing number of interdependencies. By employing Design Science Research, this study proposes an analysis that supports engineering managers in managing sociotechnical and inter-organizational change integration (MOSAIC) by facilitating a structured, multidisciplinary assessment of system impacts and interdependencies. The design was evaluated by applying it to an inter-organizational project in the Dutch railway system. The findings show that with MOSAIC, a system of interest can be collectively defined using the proposed process and a multidisciplinary and inter-organizational group of experts, creating mutual understanding. MOSAIC can further aid engineering managers in front-end project planning.","PeriodicalId":54353,"journal":{"name":"Engineering Management Journal","volume":"1 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43582584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It aims at analyzing how risk allocation occurs and its implications. A case-based research approach was applied, combining qualitative and quantitative analysis strategies. This research in-depth examines four large PPP projects in the Brazilian metro-rail sector. Dyadic archival and interview data were collected from public-private parties, including 34 interviews, and archival sources, such as contracts and reports. The results identify the critical success factors and risk factors in PPP projects in the transport sector. The analysis shows that public and private sectors pursue different critical success factors but converge on the risk factors. The most stressed risk factor is “corruption and bribery,” which reveal the corrupted context spanning in the studied projects. Finally, the conflict in perceptions shows an explanation of context-dependent aspects explored in the qualitative analysis.","PeriodicalId":54353,"journal":{"name":"Engineering Management Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44861608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, building and enhancing the organizational resilience of construction projects is a priority for construction organizations. This study seeks to advance this literature by exploring the combination of conditions to enhance resilience from resource and institutional perspectives. Specifically, resource-based theory and institutional theory are used to identify factors that affect the organizational resilience of construction projects, and fifteen representative Chinese projects are selected. A conditional combination is explored to build organizational resilience from pre-crisis and post-crisis perspectives and make a comparative analysis. Results show that institutional factors dominate the construction of proactive organizational resilience, whereas resource factors play a major role in enhancing reactive organizational resilience. Organizational norms are the main guarantee for the crisis response of construction projects whether before or after a disaster. This study contributes to understanding the dynamic changes of organizational resilience in construction projects. The findings provide a basis for enhancing organizational resilience, focusing on crisis preparedness and recovery efforts to respond to frequent and unexpected challenges.","PeriodicalId":54353,"journal":{"name":"Engineering Management Journal","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47623053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
