Abstract: There are a lot of uncertainties in the collaborative Maintenance,Repair and Overhaul/Operations (MRO) service chain of complex product,and the relationships are disorganized and cannot be effectively analyzed and modeled.Based on analyzing the characteristics of complex product's collaborative MRO service chain,the structural model of collaborative MRO service chain was built.Uncertainty modeling and analysis methods of complex product's collaborative MRO service chain were proposed,the sources of uncertainty were analyzed in the view of structure units and service process view of the collaborative MRO service chain of complex product,the concept of dominant uncertainty and recessive uncertainty were defined,and an uncertainty transmission relationship model was constructed.By considering the influence of variation range and the corresponding probability functions of the uncertainty factors,an uncertainty sensitivity analysis method for collaborative MRO service chain of complex product was proposed.Results of the case study showed that the proposed method could support the uncertainty prevention control of complex MRO collaborative service chain.
