STRATEGIC costs management at societies group level. Multicriterial model for optimization

In our opinion, the performances at group level must be analyzed differently, depending on the adopted strategy. Thus, we consider that a major problem of the accounting and cost control is their compatibility with the strategy. This is justified by the fact that a certain system, that can be an efficient instrument for assessing the performances of a group whose strategy is cost dominated, could cause malfunctions in a company that adopts a differentiation strategy. Because groups’ management currently faces a specific problem – adopting decisions when several objectives are followed simultaneously or the same objective common for more branches – we consider that, in such cases, the decisions cannot be based on a classic model of optimization of a single objective function. We consider that an optimization model with several objective functions, which aims at optimizing the costs for the subsidiaries and choosing a satisfactory solution for the company, is necessary.
