A Research on Maintenance and Support Cost Model of the Complex Equipment

Presently, the maintenance and support costs estimate of the complex equipment depends merely on experience. Through the analysis on the feature and expenses of the maintenance and support, we use the theory about the membership degree and closeness degree in the fuzzy mathematics. According to the thinking of the smoothing index modeling, an estimating model for the maintenance and support based on the nearby principle is established. Using the computational analysis on the new equipment B, we verify its dependability.
