Research on Optimization and Decision Making Methodology in Technology Design of Coal Mine Refuge Chamber

摘要

In this paper, an effective optimization and decision making method was proposed to deal with the multiple attribute decision making problems in technology design of coal mine refuge chamber. It is more reasonable that both attributes' subject weights assessed by experts (DMs) and intrinsic weights inside the alternatives are taken into account. The main factors, which affected DMs' decision making, were analyzed and subdivided to 14 elements, and then a MADM model for chamber design was introduced subsequently. A case was studied to demonstrate the application of the model, and the results show that the chamber's capability of withstanding overpressure, temperature control, flexibility and investment cost are crucial elements which are connected with the product's superiority and should be paid more attention in technology design.
