Effectiveness evaluation of smart equipment support information system based on Entropy-Revised G1 method

Focusing on the complexity of the structure and the diversification of indicators in the equipment support information system, a combination weighting method was proposed to evaluate the system effectiveness. Firstly, based on the working principle of the equipment support information system, this method constructed its evaluation indicator system; Secondly, based on the subjective and objective characteristics of the indicators, it determined the weight of each indicator by combining the entropy method and the G1 sequence method; Subsequently, through the comparative analysis of the model, the efficiency ranking of the system was carried out. The results of theoretical analysis and simulation verified that this method is an effectively integration of qualitative and quantitative analysis, and is a feasible plan in the effectiveness evaluation of equipment support information system.
