Optimal placement of maintenance facilities

Abstract

The article deals with the placement of service facilities and infrastructure. The most typical statements of problems are given. It is shown that the greatest difficulty is the simultaneous consideration of budget constraints and restrictions on the relative location of objects. It is shown that the application of the method of dynamic programming, in many ways can solve these problems. A heuristic algorithm for solving the problem is proposed. The issue of determining the rational number of objects intended for placement is considered. In this case, the problem reduces to determining the matching of maximum power. A heuristic algorithm is proposed that allows you to determine the required number of objects to be placed.

The use of energy-saving technologies in the overhaul and reconstruction of buildings

“…The redacting indicator is the discounted payback period, which should not exceed the interval between overhauls equal to 25-30 years. Efficiency assessment is carried out separately for investments attractive to the government and investments attractive to end consumers as shown in formulas 1 and 2 [9,10].…”

“…The study of the essence of the energy saving potential of buildings, as well as the study of regulatory documents, economic literature and the existing practice of energy saving in the Russian Federation, showed that the definitions used for the concept of "energy saving potential" do not fully take into account the specifics of operating public and residential buildings. In most buildings, energy efficiency is achieved by eliminating the use of such life support systems as ventilation, which leads to a violation of sanitary requirements established for this type of buildings and a decrease in the comfort of staying in them [1].…”
