Study on Prediction Method of Spare Demand Rate and Determination of the Storage Quantity During Military Medical Equipment Maintenance / 医疗卫生装备

ABSTRACT

Objective To study the spare demand rate and storage quantity probability model for military medical equipment in order to make a valuable reference to the decision-making of medical organization for the further medical support.Methods The reliability and maintainability of spare in the process of equipment maintenance were studied,and the signifi-cant factors which have influence on spare demand rate were analyzed.By using Passion theory,spare demand rate proba-bility model of medical equipment was deduced,especially for repairable components and un-repairable components spare.By calculating the probability of replaceable spare,a useful method to scientifically make out the storage quantity of mili-tary medical equipment was provided.Results The models of spare demand rate and storage quantity were made for mili-tary medical equipment maintenance.Conclusion The solution of the model is simple and convenient and the calculating results shows that the spare demand rate and storage quantity is close to the reality.It can meet the requirements of pre-diction of spare demand rate and determination of the storage quantity in maintenance support of medical equipment in peacetime.
