Logistics Sservice Supply Chain Capability Decision Optimization Research

In the operation of logistics service supply chain is always present many uncertain factors,it is precisely that the existence of such random uncertainty that will cause the imbalance of supply and demand structure of logistics service supply chain to a large extent.Therefore,based on the premise of stochastic disturbance of demand and output,it is necessary to study the logistics service supply chain capability decision.Based on this,this paper mainly studies two aspects: First,the ability of logistics service supply chain decision-making research,based on game theory,building a single cycle ability of logistics service supply chain decision under static game model,and the dynamic evolution of logistics service capacity decision variables is studied by combining the static solution of capacity decision and system dynamics in a single period static game.Through the research,it is found that the bullwhip effect exists in the process of multi-cycle game,which will cause the increase of decision error.Secondly,the research of logistics service supply chain capability decision optimization based on information sharing.The main goal is to optimize the decision-making by building a decision-making model of logistics service capability based on information sharing.However,in reality,there is great resistance to information sharing,and members often do not easily disclose private information.In order to motivate logistics service supply chain node enterprises to choose information sharing,At the end of this paper,the information sharing behavior of logistics service supply chain members is analyzed.The main research results of this paper are as follows:(1)Under the realistic condition of stochastic disturbance of demand and output,the logistics service supply chain capability decision model is constructed based on game theory.The results show that the value of capacity investment is significantly greater than the value of order,and both variables are affected by capacity output factor,retail price,etc.,and the capacity order and capacity output are positively correlated.The capacity ordering-investment reserve coefficient is introduced to represent the relationship between the two.The coefficient is not only affected by wholesale price,unit penalty cost,residual value and unit capacity investment cost,but also affected by the yield rate.The larger the mean yield rate is,the larger the coefficient is,and the larger the variance of yield rate is,the smaller the coefficient is.(2)Combining game theory with system dynamics,analyze the dynamic evolution law of ability decision value.The results show that the amount of investment of logistics service providers has a high dependence on the amount of order.The three dimensions of logistics service capacity decision-making variables(order amount of logistics service capacity and investment and reserve amount of logistics service capacity),logistics service capacity holding and bullwhip effect value are explored.The simulation results show that: Provider of logistics capability of the investment is bigger than the average and range of market demand,logistics service capability holdings range is larger,the simulation results prove the problems existing in the logistics service capability of supply chain decisions,the bullwhip effect value of 3.55,indicating that the basic model of logistics service ability to produce the bullwhip effect in the process of decision-making.(3)The information sharing mechanism is introduced into the logistics service supply chain ability decision-making foundation model,the results show that compared with the basic model of information sharing model volatility of logistics ability decision amount is reduced,the logistics capability to supply relatively stable at the same time,no longer need to prepare too much ahead of logistics service ability,can better respond to the change of market demand,Moreover,the bullwhip effect value is reduced to 1.43,which reduces the waste of human and material resources to a certain extent,proving that information sharing has a certain coordination and optimization effect on logistics service supply chain capability decision.(4)Based on evolutionary game theory,a selection model of information sharing behavior of nodal enterprises in logistics service supply chain is constructed to analyze the development and evolution process of information sharing behavior of nodal enterprises and the influence of various factors.The research finds that: Both sides choose information sharing strategies and both sides not to choose information sharing strategy is a dynamic stable strategy,but also for policy makers to choose reverse in information sharing behavior affects the cost of information sharing and risk sharing coefficient,and sharing of information,risk factors,information absorption ability,coordination and incentive coefficient have a positive incentive to its,And there are thresholds for changing evolutionary paths.
