To determine whether a transport problem has a solution , you can use the Lagrange multiplier method . To do this, it is advisable to replace variables so that the objective function is a sum of exponentials. The peculiarity of the sum of exponents is that the principal diagonal minors of the Hessian of the sum of exponents are positive quantities , and therefore the sum of exponents has an extremum and this extremum is the minimum. Solutions of large - dimensional transport tasks are of great practical importance for optimizing transportation schedules by transport enterprises . There are several algorithms for solving this problem, but the development of other methods for solving the transport problem that would use computing power more efficiently deserves attention. The method proposed in this paper for solving the transport problem based on the use of complex numbers in the algorithm makes it simpler and more visual for practical application.

To create conditions that ensure the competitiveness and high quality of products, an industrial enterprise should have a system for managing the quality of products. This should include product quality management at all stages of the production cycle. Product quality management should be comprehensive, involving the use of organizational, economic and technical measures. A comprehensive quality management system at an enterprise should be based on the quality standards adopted at that enterprise. The evaluation of the quality of the products produced from the point of view of its buyer is subjective and depends on the usefulness of this product to a particular consumer. It is advisable for an enterprise to track consumer preferences in order to make its products better from the point of view of customers. After-sales service is an important element in the way of promoting products on the market. The organization of effective service requires the coordination of technical, marketing and commercial activities, taking into account consumer preferences.
