Abstract:

The problem of optimization of equipment multi-echelon spare part carrying project with support efficiency under multi-index constraints is studied, and the method for evaluation of equipment is proposed. Firstly, the influence factors of spare part carrying are divided into two categories: direct constraints and indirect restraints, and the cloud model is introduced to make the conversion between them. Secondly, the analytical calculation equations for spare parts demand rates of multiechelon support sites are given. Thirdly, three support efficiency indexes are considered as constraint condition, four constraint are taken as the objective function to establish a model. Fourthly, the model is solved and optimized. Finally, the model is tested to be scientific through contrastive analysis of examples.
