Summary. All manufactured and in operation equipment over time comes for disposal. During recycling there is the dismantling of its components and their processing to produce secondary raw materials, which in turn is necessary for the production of new parts. However, in the case when some parts or assemblies have residual resource, i.e. can be further used, it is advisable to remove them from the disposable equipment and to use as spare parts. Organizations, which act together in one or several enterprises, can be engaged in dismantling and implementation of units, components and parts. The article considers the interaction of two independent companies, a dismantling business on one side and a spare parts store on another one, during the selling of secondary spare parts. The degree of dismantling can vary: the equipment can be disassembled into units or fully to the details. In these cases both the complexity of operations and financial results will be different. To determine the situation of mutual expedience of partners (equilibrium situation) it is reasonable to use the mathematical apparatus of bimatrix games. In our case, the two partners – partner "A" the dismantling business, partner "В" the seller – have two strategies of behavior. All possible cases of a profit with their selection on the example of the disassembly of the tractor engine D-240 are described by payment matrices. To determine the equilibrium situation the auxiliary parameters on the basis of the payment matrices are calculated. The equilibrium situation is determined by the graphical method in solving inequalities. In the end of three equilibrium points were determined. Two equilibrium points show a pure strategy of partners (this is possible in the case of a certain agreement between them). The third point shows the equilibrium in mixed behavioral strategies of partners. In this case, both partners make a profit, regardless of the behavior of each of them. In this situation, the part of the units are sold without disassembling, the other part is fully dismantled and implemented.
Keywords: disposal, secondary spare parts, matrix, bimatrix games, technique of retired.
