Abstract

Spare parts are important material foundation of equipment use and maintenance, spare parts forecasting is the core and key of equipment protection scheme. Spare parts of fully-mechanized coal mining machinery were classified according to three type of life distribution of exponential distribution, normal distribution and Weibull distribution. Three models to calculate the demands for the three types of spare parts are established respectively under the condition of satisfying spare availability and application example of spare parts of fully-mechanized coal mining machinery was given.
