Development of a simulation model for the supply of spare parts for heating equipment

The problems associated with the supply of spare parts for heating equipment are considered. The main stages of development of a simulation model that allows you to simulate the incoming flow of applications for different types of parts for heating equipment are presented. The analysis of the time series of the supply of parts for heating equipment. Then there are opportunities for modeling autocorrelated flows by ordering for spare parts that have a certain relationship between each other according to the items of the item. Cross-correlation and autocorrelation functions of time series were considered, and it was revealed that these functions are not similar to each other.
