The maintenance model of group of stationary objects in a one-dimensional working area by moving processor is considered. The processor performs one-step service cycle without interruptions, which begins and ends at the base point. For every object assumed to be given its location, the required length of service, an early start of service and function of the individual fines. We study the problem of multiple criteria, where total traveled processor length, time of return of the processor in the base point after the service of all objects of a given group and the total fine value of all objects act as minimized criteria. The solution is performed using formulas based on the principle of dynamic programming, and also based on the ideology of evolutionary genetic algorithms. When using dynamic programming we study questions of construction of complete sets of effective assessments. The problems of comparing two sets of estimates, the computational complexity, an example and results of the experiments are considered.

After accession of Russia into the WTO the tasks related to the development of infrastructure have been sharpen. With the growing volume of cargo traffic and the lack of opportunity for the extensive development of the port infrastructure, the alternative of building the dry port can be only feasible, although explicitly the most expensive. Due to this reason the method of gradual development of the dry port which provides significant economic efficiency was addressed in the article.

Keywords: dry ports, net present value, the efficiency of the investments
