Evaluating the Risk of Natural Gas Pipeline Operation Management in Intuitionistic Fuzzy Linguistic Environments

摘要

Natural gas pipeline has been regarded as the most cost effective and safest channel of gas transportation and has extraordinary strategic significance for the country. There is a need to control the risks during the operation so as to operate the pipeline safely and smoothly under the complicated business environment. In order to evaluate the risk of natural gas pipeline operation management, this paper proposed an approach to evaluate the risk of natural gas pipeline operation management in intuitionistic fuzzy linguistic environments. Firstly, the evaluation criteria of the risk of natural gas pipeline operation management are established from the strategic risk, market risk, financial risk, operation risk, and legal risk aspects. Then experts are invited to evaluate the risk level and the weight of criteria using the linguistic terms. Rating values with regard to the criteria are in linguistic forms; the linguistic terms are modeled with the intuitionistic fuzzy linguistic model. The linguistic ratings are aggregated as the final results. Finally, the example is given to illustrate the feasibility and practicability of the proposed method.
