Abstract:

The level of repair analysis (LORA) is an important content for integrated logistics support. Aiming  at the  incomplete of existing research on the LORA problem, under the background of shipborne equipment maintenance support,  considering the repair cost as well as the repair effect, the cooperative programming model of LORA is established.  According to the fuzzy optimum selection theory, the multi-objective decision making optimization function of LORA  based on the positive and negative ideal solution is given. The adaptive particle swarm optimization algorithm is applied  to solving the LORA model. In a given example, the optimization result is gotten, through which the rule of  LORA is  analyzed, and the rationality of this method as well as the correctness of LORA model is proved. The LORA decision model  constructed is an important complement for the existing research, which has large significance 〖JP2〗for consummating  maintenance theory and supply decision support for implementing the work of equipment logistics .
