Research On The Resilience Simulation And Optimization Of Sinopec's Import Crude Oil Supply Chain

Oil is one of strategic resources which has great effect to the national economy,and is the focus for all countries as well.With the everlasting bigger pace of economic growth in China,the growth of oil demand has been becoming particularly prominent.Although China is currently carrying on economic structure transformation,it is still the biggest energy consumption and net import country.Sinopec's crude oil import accounts for over 70% of total crude oil import of China,once Sinopec's import crude oil supply chain suffered a huge impact,it would cause a serious threat to the oil security of our country.Since the import crude oil sources and transport routes of Sinopec are mostly restricted by other countries,this leads to greater risk.Therefore,only if the resilience of Sinopec's import crude oil supply chain be enhanced,can the loss caused by disruption be reduced,and can China's oil security be guaranteed effectively.In order to study the route to enhance the resilience of Sinopec's import crude oil supply chain,this dissertation carries out from the following three parts.Part one is theoretical analysis.Firstly,the supply chain structure and operation status of Sinopec import crude oil are analyzed,and the problems in supply chain are extracted.The analysis of these problems are lacking of resilience.The dissertation analyzes the environment of Sinopec import crude oil supply chain system,extracts the interference factors which will cause serious negative impact on supply chain,and analyzes and summarizes the disturbance caused by interference factors.It provides theoretical basis for the following simulation model and simulation experiment.The second part constructed the resilience simulation model of Sinopec import crude oil supply chain,and carries on three strategies including the simulation experiment to the defensive inventory,the emergency procurement and the standby route,revealed the influence of the three strategies on the resilience.The third part takes the moderate resilience as the goal,optimized the resilience of Sinopec's import crude oil supply chain,get the optimal solution,and put forward the resilience optimization strategy suggestion.The final result of the dissertation is to establish the elastic simulation model of Sinopec's import crude oil supply chain with the help of the dynamic simulation method,which is based on the simulation model.At the same time,taking the moderate resilience as the optimization target,the optimal solution is obtained,which provided a new way for Sinopec to enhance its resilience.
