Multi-criteria group decision making for pipe material selection: comparative analysis of HF-Vikor and HF-Electre II

The material has an important role in an engineering design field. The suitable material selection for a particular product is one of the multiple criteria decision making (MCDM) problem depends on an aggregation representing by closeness to the ideal which is generated by compromise methods.  In order to complete the product requirements, experts need to analyze the performance of various and suitable materials with precise operations. In the competitive market, the material selection process is intricate and time consuming effort. There is a need to choose an efficient approach for the selection of best alternative material of a product. The purpose of this study is to solve a MCDM problem of pipe material selection in a group, in addition, give a comparative analysis of hesitant fuzzy VIKOR (HF-VIKOR) and the hesitant fuzzy ELECTREE II (HF-ELECTREE II). An example of pipe material selection of Jamal Din Wali sugar industry in Pakistan is conducted to illustrate the application of the proposed approach; finally, the ranking performance of these MCDM methods is also compared with each other.
