ABSTRACT

Ship production occurs at the end of a complex process and needs effective and efficient Project Management (PM). Uncertainty in project management parameters always exists and is inevitable. The Fuzzy Set Theory is capable of capturing uncertainty through the membership functions of the parameters. We proposed a model of Interval Type-2 Fuzzy Sets (IT2FSs) Program Evaluation and Review Technique (PERT) method to literature and applied this to the production scheduling of an electric yacht to study this proposed method in terms of PM in the shipbuilding industry. The proposed model contains Forward Pass and Backward Pass calculations for IT2FPERT with a new ranking method, and a Slack Time calculation for IT2FPERT, which develops a Criticality Degree (CD) on the possible path for IT2FPERT and determines the Critical Path. Robustness tests of the proposed model were carried out by comparing results to the Critical Path Method (CPM), PERT, and PERT Simulation solutions.

摘要

船舶生产发生在复杂流程的最后，需要有效和高效的项目管理 (PM)。项目管理参数的不确定性总是存在并且是不可避免的。模糊集理论能够通过参数的隶属函数来捕捉不确定性。我们在文献中提出了一种区间类型 2 模糊集 (IT2FSs) 程序评估和审查技术 (PERT) 方法模型，并将其应用于电动游艇的生产调度，以研究该方法在造船行业的 PM 方面。所提出的模型包含使用新排名方法对 IT2FPERT 进行前向传递和后向传递计算，以及对 IT2FPERT 进行松弛时间计算，该计算在 IT2FPERT 的可能路径上开发关键度 (CD) 并确定关键路径。
