A New Model for Optimization of Cell Scheduling Considering Inter-Cell Movement

Abstract

Focusing on a cellular manufacturing system with inter-cell operations, a new scheduling framework is proposed in which a novel mathematical model is provided considering the cell scheduling sequence and an extended disjunctive graph model is established with multi-cell. In addition, an improved harmony search algorithm is proposed, comparison experiments show that the proposed solution can obtain the best results in most cases. To enhance further the generalizability of our strategy, an adaptive neuro-fuzzy inference system (ANFIS) structure is generated. ANFIS is based on the improved harmony search algorithm and takes the cell scheduling properties as input and the results of our proposed solution as output. Then, the optimal ANFIS structure is obtained by comparing different ANFIS structures. Finally, the ANFIS-predicted values are compared with those of the proposed solution and get a high fitting degree, which verifies the validity of the ANFIS structure.
