Abstract

An increasing number of companies are turning their attention to the company's development through various analytics, and logistics companies are not an exception. It is through quality analysis that companies can gain a market advantage over their competitors. This paper focuses on analyzing the distribution system of one of the largest logistics companies in Serbia. The analysis refers to the current company state, after which was presented the idea of defining the price that the company can offer to its future customers. Pricing is done using a simulation-optimization model developed in Python 3.7. In addition to the simulation itself, great importance is given to the development of a heuristic model for solving vehicle routing problems that contain a combination of the nearest neighbour algorithm with 2-OPT, Swap, Relocate, and Path Relocate route enhancement algorithms.
