Combination Weight and Radar Chart Based Evaluation Method for Utility Tunnel Planning in Multiple Energy Systems

With the requirement of rapid urban development, multiple energy systems are becoming more and more imperative. The utility tunnels play a key role in the multiple energy systems, which can relieve the traffic jam and environment problems. Therefore, it is an important issue to evaluate and select an appropriate construction plan for the utility tunnels. In this paper, several indexes considering the technical, economic, and environmental factors are presented for evaluating the plans of utility tunnels construction. Then, combination weight method, in which both subjective experiences of experts and objective differences among data are considered, is used to determine the weight of each index. Next, radar chart method is proposed to make comprehensive evaluation for different plans of utility tunnels construction. Finally, case studies are performed to demonstrate the effectiveness of the proposed comprehensive evaluation algorithm for utility tunnel planning in multiple energy systems.
