Abstract: To improve overall performance of production application service system and support multi-component combinatorial optimization, based on characteristics of product application service system, constituent components and their relationships were defined. Component model for product application service was constructed. In succession, the stable service chain was established to select heterogeneous product application service component. Mathematical model for multi-component combinatorial optimization was constructed which was aimed to overall fitness for product application service system. Two-layer combinatorial optimization algorithm was used to perform multi-object compromised optimization so that the optimal combinatorial optimization scheme was determined.Finally, typical application in product application service system was presented which verified the feasibility of the proposed method.

Key words: product application service component, global demand sufficiency, composition optimization, mathematical model
