Optimization Method for Spare Parts Deployment Efficiency in Development Phase
Based on the definition of spare parts deployment efficiency, factors influencing of deployment efficiency were analyzed; spare parts fill rate and utilization rate were introduced for measuring spare parts deployment efficiency. Spare parts utilization rate was calculated using Closed Jackson Queuing networks, while spare fill rate was figured out using Dynamic equilibrium equation of Logistics. With fill rate, utilization rate and cost being as constrains, optimization model of spare parts deployment efficiency was established. With SUMT which transform constrain problem to minimum question, combining horizontal search; iterate in the feasible region, optimized point can be figured out. The method will provide a new way to increase spare parts deployment efficiency.
