Analysis of Spare Parts Value on Life Circle Cost-Effectiveness

Spare parts life circle value is sensitive to various factors and has the traits of obvious uncertainty, so the comprehensive analysis of the cost-effectiveness becomes more complex. When procuring and selecting spare parts, it is necessary not only to consider efficiency, but also to consider costs; It is necessary not only to consider whether it is “affordable” but also to consider whether it is “affordable”, and strive to achieve the principle of harmonizing the advanced nature of spare parts with the sustainability. In this paper, A type of solution to the comprehensive assessment on spare parts life circle cost-effectiveness which is gray analysis method has been applied. On this basis, the corresponding weight according to relative importance of the primary factor of efficiency function to spare parts life circle cost has been determined. Finally, the assessment method is presented, and a practical example is analyzed. There are two points as for conclusions. (1) the analysis method to cost-effectiveness is an excellent mode on the science basis between the optimal usage of spare parts guarantee budget and the usage standard of its budgets, and it can satisfy the comprehensive balance relationship between a guarantee budget-usage of mission request for spare parts of an aviation department (2) the method of gray system valuation can handle the indetermination information within the analysis of the expenses-effect problem nicely, the analyzing result which has been synthesized can provides a type of path performances for the guarantee effects of spare parts such as good or bad, so as to have a better military and economy value.
