This becomes even more significant when human ...  Read More

2. Modified Pareto archived evolution strategy for the multi-skill project scheduling problem with generalized precedence relations

Amir Hossein Hosseinian; Vahid Bardaran

Volume 7, Issue 1 , Winter and Spring 2020, , Pages 59-86


  In this research, we study the multi-skill resource-constrained project scheduling problem, where there are generalized precedence relations between project activities. Workforces are able to perform one or several skills, and their efficiency improves by repeating their skills. For this problem, a mathematical ...  Read More

5. A knowledge-based NSGA-II approach for scheduling in virtual manufacturing cells

M. Zandieh

Volume 3, Issue 1 , Winter and Spring 2016, , Pages 89-107

  This paper considers the job scheduling problem in virtual manufacturing cells (VMCs) with the goal of minimizing two objectives namely, makespan and total travelling distance. To solve this problem two algorithms are proposed: traditional non-dominated sorting genetic algorithm (NSGA-II) and knowledge-based ...  Read More
