Method of Calculating the Spare Parts System Availability for Electronic Means

Abstract

The aim of research is determine the feasibility of using the methodology for calculating availability and mean delay time to demand fulfilling for spare part by local package of electronic means (EM)with a compound structure of spare parts, tools and accessories(SPTA)kit. Methodology is based on the usage of the analytical model “EM - SPTA kit” with an assessment of the failure level. The main advantages of this technique are possibility to split the main structure of the spare parts system to set of simple, possibility of calculating spare parts sets for several types of replenishment strategies, the simplicity of verification the model for assessing the availability rate and the average delay in satisfying a request for a spare part. Possibility of calculating spare parts sets for several types of replenishment strategies. Simultaneously the technique has a significant drawback, such as methodical technique gives an approximate value of the sufficiency indicators with an calculation error. At the conclusion were proved the ability to use electronic methods for calculating the availability's rate and the average latency in satisfying the request for the spare part of the spare parts kit system for some replenishment strategies, which also allows to calculate the availability rate for the “EM-SPTA system” model, which is proved to be possible for modern structures of the spare parts system.
