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.
ABSTRACT
Objective To evaluate economic benefits of maintenance for medical equipment.Methods According to the maintenance tour records taken by Institute of Drug and Instrument Control in 2007,economic benefits of 21 kinds of normal medical maintenance were analyzed by using the database of Excel 2003.Result The total benefit cost ratio was 2.73.Conclusion Investment in maintenance for medical equipment has great economic effect.
