考虑多因素的危险气体探测器选址优化方法
An approach for dangerous gas detectors placement optimization considering multi-factors
摘要
Abstract
As an important protective layer of petroleum refinery installations,gas detectors can greatly improve the detection efficiency and reduce the loss if they are placed in a reasonable position.From the perspective of minimizing leakage risks,a quantitative optimization method of gas detectors placement was proposed.Several external factors of leakage diffusion process were quantified to calculate the scenarios occurrence probability,leakage consequence and risks.According to the failure mode and redundancy structure,a minimal risk p-median problems (MRPMP-UVCVaR) optimization model was demonstrated,as well as unavailability,voting effects and Conditional-Value-at-Risk (CVaR) was considered.Particle swarm optimization (PSO) was used to solve the model.The applicability of the methodology was shown in a case study and the results were compared with the original scheme,improving the design of detection systems on a risk-oriented basis.Future work including the research of the experimental validation and multi-objective optimization will be taken to improve the practicability of the optimization model.关键词
