In this research, we study a scheduling problem in mail-order pharmacy automated distribution (MOPAD) system. In MOPAD scheduling, two kinds of objective: the collation delay (CD) and makespan, should be considered and in the previous study of some of authors three kinds of genetic algorithms (GA) are applied and evaluated. In this paper, we apply constraint programming (CP) for the scheduling problem...
We consider the multidimensional knapsack problem (MKP) with min-max regret criterion under interval profits. We examine three typical algorithms widely applied for min-max regret criterion: fixed-scenario approach, Benders-like decomposition and branch-and-cut. We further propose a new heuristic framework, which we call the iterated dual substitution algorithm. Computational experiments on a wide...
As the foremost step for designing a cellular manufacturing system, cell formation is a hard optimization problem. It is necessary and significant to develop methods to find near-optimal solutions in a reasonable time. In this paper, the first hybrid discrete Cuckoo Search (HDCS) algorithm is designed to address the cell formation problem. Alternative process routings and operation sequence of parts...
