Развитие VMI-отношений горнодобывающих компаний и поставщиков операционных ресурсов
For mining enterprises, the need for spare parts and consumables used in the repair and operation of equipment depends on a number of factors, and the degree of influence of each of them is not unambiguous and has a more probabilistic (stochastic) nature. Therefore, the recommendations of the equipment manufacturers, which are present in the technical documentation, are more general (universal) in nature. In circumstances where it is not possible to unambiguously determine the actual need for operating resources, mining companies are forced to form additional insurance stocks necessary to ensure an uninterrupted production process and maintain productivity at a given level. To reduce the negative impact of uncertainty of the environment, it is advisable to build relationships with suppliers based on VMI technology. The calculations were made taking into account the total costs associated with the organization of orders and supplies from suppliers and consumers. The proposed solutions were based on using the model of the optimal order size in the supply chain, taking into account losses, both from immobilization of financial resources diverted to inventories, and from downtime of technological equipment. The article proposed a list of items of expenses that should be taken into account when calculating the total costs associated with purchases and stocks of operating resources of mining companies. As a result of calculations in the article, it is shown that with the development of VMI relations between mining companies and their suppliers, it is possible to achieve a mutual cost reduction, while reducing inventory levels, by increasing transparency and certainty when planning the demand.
