Volume 2, Issue 3 , September 2013, , Pages 47-57

Abstract
  In this paper, we study a resource-constrained project-scheduling problem in which the objective is minimizing total Resource Tardiness Penalty Costs. We assume renewable resources that are limited in number, are restricted to very expensive equipment and machines, therefore they are rented and used ...  Read More

2. A Hybrid Genetic Algorithm/Simulation Approach for Redundancy Optimization with Objective of Maximizing Mean Lifetime and Considering Component Selection

H. Karimi; A.A. Najafi

Volume 2, Issue 2 , June 2013, , Pages 35-46

Abstract
  In this paper, we consider a reliability redundancy optimization problem in a series-parallel type system employing the redundancy strategy of cold-standby. The problem consists of two parts component selection and determination of redundancy level of each component—which need to be solved so that ...  Read More
