Support of planning heat treatment processes in small batch production is very complex. In the analysed case, the bottlenecks of the processes were located on heat treatment. The difficulty in planning is due to necessity of adapting available resources to changing demand requirements. In the conditions of unit production crucial role plays changeovers time, availability of resources and cost of processing. Due to NP- difficult nature of optimization a simplified method was used. It was a complex of theory of constraints and dynamic task grouping. This is one of the attempts to solve the supporting process production problem with a method enabling its practical use.

Dynamics on the market makes, that search for more effective solutions in planning the production flow. Opportunities, which open the market for companies, as new basis of cooperation, have to go hand in hand with the flexibility and ability to adapt to the requirements of the environment. The problem of scheduling production flow is more complicated, because the virtual manufacturing network create a single organizations, geographically dispersed, functioning temporarily, as a one body, to realize the effect an order. In the whole production planning and choosing the route from alternative routes should be considered still a problem of transport between the participants in the virtual network. To planning the flow production and choice of route used formalisms derived from game theory. The article presents the record of the decision problem for the production model in which the role players perform the goal functions. This functions have specific strategies and endeavour to win. The choice of strategy depends on which player starts the first game. Further work will be associated with the analysis of the impact of different combinations of strategies on the results of the game, with certain restrictions, as well as attempts to implement formalism to choose strategies in mixed strategies.
