The multisourcing model of safe supply chain management

The logistics outsourcing concept is to address the feasibility of using its own capabilities and sources of supply to perform certain logistics functions that the company can entrust to an external partner. However, in the current context of rapid change, it is important to make a quick and efficient decision on sources of supply: regardless of the sourcing model of the company. That is, what is the usual supply strategy for the company. Security (reliability and stability) of supplies is at the first place. Therefore, a quick decision on the optimal source of supply is the optimal solution. More precisely is the optimal combination of the use of internal resources of the company and the resources of external suppliers. Multisourcing is a type of outsourcing used by many companies in conditions of frequent changes. Unlike traditional outsourcing, the multisourcing model involves the use of several different vendors for the same product at different times. The decision depends on the level of security. For example, with multiple sources, a company can choose the best supplier for a particular task. By outsourcing certain operations, a company can perform critical tasks on its own. These actions can achieve optimization of operating costs. However, when deciding on multisourcing, it is important to assess the risks. It is important to estimate the cost of supply according to different options. You should compare the results of calculations and compare with the risks. These actions can ensure security of supply. So, the proposed economic and mathematical model is able to help to make the right decision of the rational choice of supply channel from several alternatives and, as a consequence, to achieve the following main goals: improving the quality of supply management; reduction of the logistics cycle; reduction of supply costs; increase the reliability of suppl
