Abstract: To reduce risks of Virtual Enterprise (VE), a novel Distributed Decision Making (DDM) model for VE risk management was presented. This model had two levels, namely, the top-model and the base-model, which described the decision processes of the owner and the partners, respectively. The owner allocated funds to each member of the VE, the partners then selected their own optimal risk control actions to reduce their risks with the constraint given by the allocated budget. When number of members in VE, the number of risk factors and the number of actions increased, the size of the search space would be very huge. Aiming at the feature of many members of VE, a Multi-swarm Particle Swarm Optimization (MPSO) algorithm was then designed to solve the optimization problem. Simulation results revealed the effectiveness of the proposed algorithm.
