The dissertation work is devoted to the decision of an actual problem in the field of program management – development a methodology of road maintenance program management, which allows to perform modeling of a projects package in the program according to a certain set of goals, factors and taking into account uncontrolled influences.
The theoretical study of projects, programs, strategies types and methodological approaches to the repair and restoration measures impact on the road network condition showed the need for changes in the paradigm of system management of road maintenance programs, in particular, it is necessary to apply long-term planning which is based on ensuring the quality of roads, rather than on the volume of work performed as in traditional approaches.
The following analysis was conducted based on foreign experience in developing a methodology for operational maintenance managing programs of roads. On the basis of the conducted theoretical researches the conceptual model of development of road maintenance program management methodology based on the thesaurus, models, methods, criteria and management tools was formed. A number of new definitions have been added to the existing program management thesaurus. The model of strategic planning of the program management of a road network is improved and the architecture of road maintenance program management model is developed.
The mathematical model of the restoration strategy substantiation of a road condition on the basis of the projects which are realized through long-term road maintenance contracts on the principle of maintenance of their operational condition is improved.
Adjusting the values of variables, the mathematical model of project optimization in the program selects a possible solution (in terms of constraints) with the best (optimal) value of the defined objective function. When deciding on the model, the variables are represented by a set of strategies that correlate with the road maintenance objectives. The economic evaluation of the project in the program is proposed to be carried out using current cost and net present value, and annual payments for the program or individual project – to be determined by the approach of the Transportation Association of Canada. It is proposed to prioritize road sections according to a set of factors taking into account uncontrolled influences by optimization methods, in particular, genetic algorithms are defined as the most progressive method for finding solutions.
The methodology of road maintenance programs is substantiated, which is based on the use of the method of analysis of AHP Saaty hierarchies and methods of optimization by a set of goals, factors and uncontrolled influences. The mathematical model of project optimization in the road maintenance program is supplemented by the risk factor of strategy failure. The visual model of projects optimization in the program is developed and the algorithm of road assets condition forecasting under the program is improved.
The algorithm of decision-making on management of road operational maintenance program and algorithmic decisions to software complexes and information-analytical systems are improved.
Key words: maintenance program, project package, program management methodology, strategy, goals of management, road condition, maintenance.
