TL;DR: In this paper, a Graphical Evaluation and Review Technique (GERT) network based remanufacturing process model was proposed to analyze the uncertainties of remanufacture process routes,parameters were described and four typical remanufacturation process routes were introduced, and the probable route for each process and time distribution function of every process time were discussed.

TL;DR: In this article, the authors used Resource Assignment Petri Net (RAPN) to model a ship repair project, which enables project managers to represent and evaluate different resource assignment strategies and interactions among activities and resources.
Abstract: Abstract—Managing a project is a complex task. Traditional project management tools and models such as Graphical Evaluation and Review Technique (GERT), and Venture Evaluation and Review Technique (VERT) have not adequately incorporated a number of factors which can influence the resource assignment of projects. Consequently, it is essential to use powerful tools such as Petri nets in order to provide models which are closer to real-time ones. In this paper we use Resource Assignment Petri Net to model a ship repair project. This approach enables project managers to represent and evaluate different resource assignment strategies and interactions among activities and resources. Index Terms—Coloured petri nets, project control, RAPN.

TL;DR: It could be assert that, by using the designed control system, scheduling the project in a more logically and precisely way would be achievable.
Abstract: Project scheduling is one of the main fundamentals in project management so the related progressive methods which consider most of the project limitations would be valuable. The GERT (Graphical Evaluation and Review Technique) is a network analysis method which has unique capabilities in comparison with other conventional scheduling methods. On the other hand and, there is no definite conformity between the scheduling and implementation of projects mostly in the reality. So a project always accompanied by uncertainty. In this research, for decreasing the constraint’s consequences, caued by ambiguity and indecisiveness, fuzzy logic and fuzzy control system has been recommended. For this purpose, the mean, variance, value and number of loops in the GERT network and also environmental effective risks has been considered as fuzzy variables. Thus, by using capabilities of GERT network and with emphasis on fuzzy logic and fuzzy system, a fuzzy control system has been designed for the first time. In accordance with the results obtained from 15 experiments which was done among different medium-sized projects, it could be assert that, by using the designed control system, scheduling the project in a more logically and precisely way would be achievable.
