Multi-criteria decision-making of manufacturing resources allocation for complex product system based on intuitionistic fuzzy information entropy and TOPSIS

Abstract

Manufacturing resources allocation (MRA) is important area, and a significant challenge is encountered when considering high value, customized, complex structure and long lifespan of complex product system (CoPS). The relationship between uncertainty factors (i.e., inputs and outputs) of processes in CoPS’s manufacturing, operation and maintenance needs comprehensive trade-offs in the preliminary MRA stage. Meanwhile, the CoPS’s MRA schemes are contradictory from a customer’s perspective with different emphasis on operating cost related to operation and maintenance stage. These problems are unavailable in traditional expressions for model and objective function. In this paper, a new variant of MRA multi-criteria decision-making (MCDM) model of CoPS (MRA&CoPS) is developed to evaluate MRA schemes with considering CoPS’s lifecycle. Meanwhile, considering characteristics of CoPS and customer-involved MRA process, the three-layer criteria cumulative model is established. In the proposed method, intuitionistic fuzzy sets (IFSs) based subjective–objective hybrid fuzzy method is presented to deal with uncertainty of evaluation criteria. The weights of criteria are determined by the proposed intuitionistic fuzzy information entropy (IFIE). The hybrid IFIE-TOPSIS method is proposed to obtain the optimum MRA scheme by ranking results. An example of CoPS’s MRA in a case enterprise is addressed to verify the rationality and validity of the proposed method. The results show that the proposed method is more preferable and robust in MCDM problem of MRA&CoPS.

An Integrated Group Decision-Making Framework for the Evaluation of Artificial Intelligence Cloud Platforms Based on Fractional Fuzzy Sets

“…Vikram et al [20] discussed the steps of extended TOPSIS methods applied to decision-making problems in an IF environment. Lue et al [21] also discussed the main points of the extended TOPSIS method in an IF environment. After that, Zhang and Zeshui [22] discussed the steps of the extended TOPSIS method and its applications to decision-making problems in a PyFS environment.…”

A Heuristic Integrated Scheduling Algorithm Based on Improved Dijkstra Algorithm

“…In the era of big data and artificial intelligence, product scheduling methods based on cloud computing and fog computing are also developing rapidly [5,6]. Complex products [7], that is, the use of high-tech, the use of complex processes, the number of parts, the level of product structure, the relationship between parts and products, the value of high-value products, and their demand are becoming more and more personalized and diversified. So, the problem of product scheduling in multi-variety and small-batch complex processes needs to be solved urgently [8].…”
