Abstract: To more comprehensively analyze members'random behavior and fuzzy factors that influence the behavior in E-business based Maintenance,Repair and Overhaul (E-MRO) and to promote the achievement of a long-term win-win situation,a fuzzy-stochastic programming based win-win service policy was proposed.An E-MRO service chain framework was constructed,and the stochastic programming was combined with fuzzy programming in the proposed model.Fuzzy multi-variate random variables and multi-choice parameters variables were introduced to quantify relevant factors'randomness and fuzziness in E-MRO,and the profit sharing was introduced to balance risk and profit of the two parties.By using Lagrange interpolating polynomial and global criteria,the multi-objective fuzzy-stochastic programming model included multi-choice parameters was solved,and the price of MRO and quantity of corresponding resource allocation for long-term win-win situation were obtained.The results of experiment and application case analysis validated the feasibility and efficiency of the proposed model.The results also showed that stable cost of resource allocation,small fluctuations of MRO price and conservative risk appetite of Collaborative E-business Platform (CEP) could promote the achievement of win-win situation.
