The Relationship Study Of Key Factors In Simulation Exercises And Auxiliary Decision-making On The Gas Emergency Repairing

With the rapid development of national economy in recent years, natural gas transportation scale is growing. As the advantage of cost and safety, most of the countries and regions adopt the way of pipeline transportation. In the process of running,gas pipeline through a longer path, complicated terrain, and subject to mechanical damage, natural disasters, internal and external factors such as corrosion and the third party activity influence, may cause partial or whole of the pipeline failure.According to the proportion data of the factors(causing pipeline leakage) shows that corrosion leakage and natural damage are the main influence factors of Beijing city gas pipeline network failure. Besides, the degree of pipeline corrosion and aging damage is unpredictable. Natural gas pipeline network in the event of an emergency situation,emergency department can be rapid response, emergency rescue and excellent ability to repair, can according to the emergency procedures with the fastest speed, the optimal scheme, the most mature repair scheme dealing with safety emergency, determines the key point of safe disposal of the emergencies. Underground gas pipeline network routine emergency has a tendency to increase year by year, it leads the safety management work of underground gas pipeline in a grim situation. At the same time, extracting and analysizing the key factors of the repairing link, setting up imulated rehearsal scheme of aided decision-making for the accident based on multi-agent, compiling unified simulation exercises plan with rapid, timely and reliable action in the processing of sudden gas leakage emergency has become gas emergency department priority.In this paper, as the object of gas pipeline leakage, in order to standardize the repair process and improve the working efficiency of the repair as the main target for research.We carried out the following tasks:(1) Research the basic elements of pipeline leakage, according to the seven indicators, including people, machine, material, method, ring and emergency details,on-site environmental risk control to summarized nearly 200 kinds of elements in repairing operations, In accordance with the Analytic Hierarchy Process(AHP)knowledge of the key factors of the weight calculation, the proportion of weighting factors and the correlation of these key factors. Familiar with typical tangent process and know the functions of various kind of factors would have to pay in the repair.(2) Carry out the simulation practice based on the Multi-Agent in Any Logic platform. In fully learning Agent classification, communication mode, the model and its communication, collaboration, related technology, the Multi-Agent in collection methodsshall be redefined.(3) The innovative work. Learn and master the Agent theory and modeling method,combined with typical examples by tangent assignment, the whole process of simulation exercise has been set in Any Logic platform. At the same time, the conclusion in the result(1) is applied to the simulation exercises, and finally set out the 23 factors playing an important role in the rescue operation, this attribute partition, modeling and parameter setting, eventually rehearsed and optimized. The core of this paper is also the Agent cooperation more time scheduling algorithm is applied to this process, comparing the practice effect and the theory analysis, finally it is concluded that repairing time can be to reduced by nearly twenty percent when emergency workers and individual processes operating at the same time. As phased research results for the follow-up of practical engineering application and laid a theoretical foundation and reference value for further study.
