Evaluation And Game Analysis Of Open-pit Coal Mine Pit Logistics Outsourcing Transportation Fleet

Among the various processes of open-pit mining,its logistics process occupies an important part.Whether it is in the development of a deposit or in the transportation of raw coal to a coal washing plant and other processing locations,the planning of its logistics system affects the production of the entire mining area.effectiveness.Therefore,it is reasonable to model and optimize the open-pit coal mine pit logistics outsourcing transportation process to reduce the cost of pit logistics expenditure and improve the overall production efficiency of the open-pit coal mine.We can regard this research as two problems.The first part focuses on the comprehensive quality evaluation of the outsourcing fleet of open-pit coal mine pit logistics dump truck transportation: the research idea is to first use the Delphi method and Likert The scale method collects the raw data of expert opinions.Next,using the AHP method as the framework,an evaluation mathematical model is established.According to the actual situation of research questions,fuzzy array of traditional AHP analysis algorithm has been improved.Right fuzzy matrix is calculated by weight and,ultimately,to evaluate the score of each outsourcing teams,prioritize and evaluate score.The second part is the bargaining game with outsourcing fleet: In the research of this problem,this paper firstly completed the original bargaining game model from the "one-to-many game" to the "one-to-one" based on the establishment of the first step priority The transformation of the "gaming" problem.Next,by exploring the influencing factors of the gaming process,psychological expectations,discount factors and other parameters,the bidding process of the coal enterprises and outsourced fleets and the game equilibrium were modeled.Then,in the above theoretical model studies on the two parts,a calculation example.Taking Xinjiang Tianchi Energy Co.,Ltd.as an example,after an introduction to the production background,first,an expert questionnaire is used to evaluate the Evaluate the evaluation factors of the model expert group and outsource the fleet to collect indicators of various evaluation factors and use fuzzy arrays to process the original data.Then,the evaluation scores of 10 outsourced teams were obtained through calculation of the evaluation model.In the bargaining game stage,this paper calculates the original game model through matlab,plays games on the basis of determining the outsourcing priority based on the score level,and calculates the proportion of the shared transportation reached by each fleet Keep balance with the company in each round of bargaining game...
