Abstract

The issue of fixed cost allocation in organizations with heterogeneous Decision-Making Units (DMUs) has always been accompanied by challenges related to fairness, managerial acceptance, and the stability of results. This research presents an innovative hybrid framework for fixed cost allocation by extending and generalizing the Data Envelopment Analysis (DEA)–Game Cross Efficiency approach introduced by Li et al. [1], explicitly considering the structural heterogeneity of DMUs. The primary innovation of this study is the integration of a Decision Tree algorithm as a preprocessing step, which categorizes DMUs into homogeneous subgroups based on input–output patterns, thereby enhancing the validity of efficiency comparisons within the DEA framework. After segregating the units, within each homogeneous subgroup, cross-efficiency DEA is first calculated, followed by leveraging the DEA–Game Cross Efficiency model to define the characteristic function of the cooperative game based on cross-efficiency improvements. Subsequently, using the Shapley value as the unique solution to the cooperative game, the fair share of fixed costs for each unit is determined. The proposed framework theoretically possesses the property of superadditivity, making the formation of a full coalition of units rational and stable. The efficiency and implementability of the proposed method were tested through a real-world numerical example involving the allocation of 10 trillion Rials in advertising costs among 8 DMUs in a dairy company. The numerical results demonstrated that the proposed method leads to a significantly different and more meaningful distribution compared to traditional methods and even the baseline model of Li et al. [1], such that the cost share of each unit directly aligns with its marginal role in increasing collective efficiency. These findings indicate that the proposed framework is not only mathematically fairer but also has higher managerial acceptability and applicability in real-world heterogeneous environments.
