Car Rental Supply Chain Coordination Considering Stochastic Demand And Capital Problem

In recent years,the transformation of Chinese consumers’ awareness of vehicle privatization and the increasing number of car free drivers have expanded the demand of the car rental market,which is ready to empower the car rental industry and drive the industry to update and upgrade.With the continuous improvement of the industrial value of car rental companies,the vertical alliance of the industry is the trend.In addition,the policies of healthy development and promoting automobile consumption issued by the state guide and stimulate the development of sharing economy,which has brought unprecedented development opportunities to the automobile rental industry.After the exploration period,start-up period and affected by the epidemic,the car rental industry has gradually moved towards the end and ushered in a period of rapid development.Based on the above background,taking Guangqi Honda ganghong store in Jinniu District,Chengdu as a case study,this paper studies the best decision-making choice of each participant in the secondary automobile leasing supply chain composed of an automobile supply enterprise and an automobile leasing company.Firstly,the coordination decision-making problem of car rental companies with sufficient funds is studied.Considering that the random demand and order quantity of the market are affected by the rental price,an effective rental function is constructed according to the supply-demand relationship between them,and then a revenue sharing contract plus cost sharing contract model is constructed by using the Stackelberg master-slave game principle.Then,the reverse induction method is used to solve the best decision of both participants and the system,The Pareto region of the expected profits of both parties and the system is also obtained.Finally,the influence of different contract combinations on the optimal decision of both parties is discussed by numerical analysis,and the effectiveness of the model is verified.The results show that when the contract conditions given by the automobile supply enterprise as the leader meet the Pareto region,the expected profits of both parties and the system are greater than the decentralized decision-making without contract,and the automobile supply enterprise should give a significantly lower wholesale price to maximize its own profits.Then it studies the coordination decision-making problem of car rental companies under the condition of capital shortage.At this time,the market random demand and order quantity are affected by the rental price,and an effective rental function is constructed according to the supply-demand relationship between them.On this basis,according to the financing methods,it can be divided into external financing and internal financing: Aiming at the Stackelberg game dominated by automobile supply enterprises and as the guarantor in external financing,a revenue sharing contract plus cost sharing contract model is established and solved by reverse induction method;In view of the influence of capital cost rate and capital return rate in internal financing,a revenue sharing contract with delayed payment period is established by using Stackelberg game and solved by reverse induction.Both models can obtain the optimal decision of both parties.Finally,the influence of the contract combination under the optimal variable on the expected profits of both parties and the system is discussed through numerical analysis.The results show that when car rental companies choose external financing,the loan interest rate is positively correlated with the income sharing coefficient,and the Pareto region is still effective.Car supply enterprises can ensure their best profit by adjusting the wholesale price,but too high wholesale price will significantly reduce the income sharing coefficient.When car rental companies choose internal financing,due to the influence of exogenous interest rate,the system profit will be less than the system profit of decentralized decision-making without contract,and the profit of car supply enterprises will increase.At this time,Pareto improvement cannot be realized.This paper takes the automobile supply enterprises and automobile leasing companies under the background of automobile leasing industry as the research object,brings the market random demand and capital problems into the research scope,expands the research ideas,and provides a scheme,study plan and scientific basis for the establishment and coordination decision-making of the supply chain of actual Enterprises.
