Determination of optimal repair posts’ number at technical service enterprise

Activity of the technical service industry is associated with an irregular flow of maintenance and repair work orders; therefore, the principles of the mass service system can be used when designing a net of motor transport repair enterprises. Capacity indicators of a technical service enterprise operating under market economy conditions are defined by probabilistic and statistical methods. The main goal of this work is to solve an optimization problem by calculating the optimal number of repair posts. Enterprise net income is adopted as a criterion function. The paper provides an example of an enterprise operation analysis when the maintenance zone load ratio U is preset. The following indicators (total gain, expenses for off-line post keeping, net effective income, and specific output per one post) are estimated depending on the number of repair posts.
