The problem of optimal standardization in industry is the. choice of optimal parameters concerning elements to be produced. In this paper we consider tile problem as a problem of discrete optimization and present a classification. We specially inquire the structure of permissible points and find on this base effective search algorithms for construction of solutions. Further more we demonstrate the application of those algorithms for a wide class of problems of optimization as there are for example the problem of charge distribution the problem of stand distribution of production, the choice of a stock of machine, them-traveling salesman problem.
