This article presents an example of two-dimensional implementation of the optimization calculations for the air leak in the top dead point of the engine and the oil pressure in the oil line. Calculation optimization of complex repair works in the form of an algorithm of the iterative optimization process. Defined optimization criteria for this batch of units of the car. The calculations are performed for all the investigated party repair Fund of the engines. By optimizing the number of process routes decreased by one set of repairs.

Keywords: repairs on an actual technical condition, repair works, pre-diagnosis, optimization, multidimensional taxonomy, the Manhattan metric

This article described in detail a methods to optimize the cost of system maintenance and repair of vehicles. An algorithm for the use of a process approach to the task, as well as the fundamentals of the original functionality of the developed software, enables you to perform the necessary calculations in an automated way on the basis of defined boundaries of a standardized rating scale Harrington. An example of using this technique for the company performing the maintenance and repair of trucks.
