Object - organizational-manufacturing and production machining processes of small and medium batch production of discrete type. Goal - production scheduling quality and operability improving by information technologies methods and models of manufacturing equipment capacity planning. Research Methods are based on probability theory fundamentals, object and modular approach, simulation technique, optimization technique of ant colonies and multi-objective optimization. Theoretical and practical results - an actual scientific and practical problem of production scheduling synthesis is solved, that leads to flexible manufacturing module schedule unevenness decreasing, flexible manufacturing system operating benefits increasing and high performance of flexible manufacturing module. The novelty consists in development of new graphic-analytical model of production area scheduling organizational-manufacturing process, that provides equipment distribution between technological operations in accordance to production plan including stores marshalling and transfer, that enables to take into account all production environment influences and to vary equipment quantity depending on manufacturing situation; it is proposed to use "directed" ant colonies algorithm with global rules for feromon concentration calculation and directionally proportional rules for ant transition between graphic-analytical model nodes, that allows to get decision near to optimum; for the first time the Pareto-optimization method for multi-objective problem of technological equipment scheduling is developed, that allows to take into account several factors and improves the quality of production schedule in accordance to several optimality criteria simultaneously, that increases productivity and favours timely production scheduling. The degree of implementation - the research results are implemented at scheduling of rotary bodies machining process production area, machine-building plant "Azovobschemash", Mariupol. Area of use - engineering industry.
