Abstract

Factors defining business adaptability to economic changes were identified. Creation of service clusters will provide the balance of interests for all agencies using technological machines and increase their performance. The result of the study is a solution of the optimization task aimed at determining the criteria of economic activities of a network of enterprises that service objects of amelioration with the use of various equipment. This solution enables regulating the level of materials and equipment taking into account the expected demand for repair stock and expected minimization of transportation costs for distributing stocks with estimate of the function of flow rates accounting. The system of distributing dead stocks of materials and equipment is proposed. The authors elaborated the economic-and-mathematical model for storage costs optimization when warehousing and selling unused materials and equipment. Results of testing the distribution scheme for dead stock of materials and equipment belonging to Stroytekhnika company, who is a supplier of consumables, fuel and lubricants, as well as spare parts for reclamation and road construction machinery.
