EQUIPMENT LIFETIME PREDICTION BASED ON THE TOTAL COST OF OWNERSHIP

摘要

Systems and methods include a computer-implemented method for predicting equipment lifetime based on the total cost of ownership. Historical data is received that includes maintenance costs of equipment of different equipment types. The historical data is used to generate, for each equipment type, total maintenance costs that are expected to be accumulated over a lifetime for all instances of the equipment type. An average cumulative cost of a particular equipment type is determined by dividing the total maintenance costs by a number of instances of the particular equipment type that were active at a particular age. A linear regression model is generated for a particular instance of the particular equipment type. The average cumulative cost for the particular equipment type is fitted to the linear regression model. An average lifetime of the particular instance of the particular equipment type is determined based on the linear regression model.
