Subject: study of the Park of Measuring Equipment (PME) that includes hundreds of thousands of standard samples, measuring instruments, control and measuring devices and other measuring mechanisms with different areas of application, levels of reliability, service life, levels of technical perfection and levels of technical condition. Research objectives: 1. Development of a complex of mathematical models to simulate the processes of development of PME, control indicators of PME performance as a whole, purposefully control the stages of life cycle of measuring equipment samples. 2. Development of the method which, with a sufficient degree of validity and objectivity, would solve the tasks of management of procurement and repairs both in preparation of proposals for preliminary long-term plan documents (LTPD) and to ensure control over the implementation of adopted plans. Thus, the method being developed should be fairly simple to use, easily adjustable for solving problems of different dimensions, suitable for solving the optimal control problem for PME as a whole, for a part of PME, and also suitable for solving a generalized problem for certain “aggregated objects” such as the Metrology Centers. Materials and methods: the methods of mathematical simulation, methods of comparative analysis, simplex method for solving linear programming problem, methods of program-target planning were used. Results: an approach to the solution of problems of program-target planning based on solving a series of linear programming problems has been developed. The results have been presented of using the approach both for formulation of proposals into the preliminary LTPD and also for introducing revisions (amendments) to annual plans, which are implemented in the framework of the state defense order. Conclusions: the described method and algorithms constitute an effective tool for solving practical problems of target-oriented management of PME performance indicators. Analyzers, control and measuring equipment and devices used in the field of construction and housing and communal services go through the same stages of the life cycle and have similar levels of technical perfection and technical condition as the samples of measuring equipment, measuring devices and measuring mechanisms described in the article. Therefore, the results and methods presented in the paper can be effectively used to control the performance indicators of park of devices and measuring instruments used in the field of housing and communal services and construction industry.

Subject: creation of a mathematical model based on the theory of operations research for appointing the members of construction teams when executing construction, installation and finishing works in civil engineering. Research objectives: optimization of the construction team structure from the condition of the highest possible quality of teams, which is determined by qualification, experience of the worker and the need to appoint a worker for a certain type of works. The problem of finding the optimal composition of the team is formulated as a linear programming problem. Materials and methods: to solve the given problem, a simplex algorithm was used in combination with the branch and bound method to obtain an integer value solution. The programming language of the mathematical package Matlab was used to implement the indicated methods of solution. Results: a mathematical model was created for appointing workers of construction teams. An example of realization of the obtained mathematical model is given. Conclusions: this mathematical model can be used for practical purposes for planning and organization of the construction process. The use of the model by designers will help to reduce their time expenditures, reduce the labor intensity of work and better perform the assignment of workers to construction teams, especially w

Article studies the problem of development of optimal plans of funding of activities for procurement and repair of particular samples of measuring equipment (ME) for the stock including several types of ME, under various restrictions for the funding. As the underlying research method, the simplex method for solving of a linear programming problem with equalities and inequalities constraints is used. It is assumed that as per the level of technical excellence the equipment can be modern or outdated, and as per the level of technical condition - operable or faulty. Mathematical model for record keeping of transitions of ME samples from an operable state into a faulty state is worked out. It is shown that, within the framework of this model, the indicators of modernity and operability of measuring equipment stock (MES) are linked by a linear dependence. As the optimality criterion, the MES modernity indicator is used; the MES operability indicator and operability indicators for each ME type are used as the constraints. While studying possible rational financing options, the modernity indicators for different types of ME also are used. Results of solving of the basic problem for different values of funding amounts for procurement and repairs are presented. Structure and sequence of optimal funding is revealed.
