Abstract.This effort derived a mathematical model for the allocation of rewards in project-based or teamwork cases. The model, considering multicriteria decision environment, allocates a constant monetary reward to team members in an optimal frame such that the balance of equity and equality is established using an inequality index Gini coefficient and hence Lorenz curves as post analyses of the Shapley values of $n$-person game theory. The model generates a convex combination of the Shapley vectors, which is better than its parents in inequality base. The recipe offers optimal weights of the convex combination and cumulative frequencies of team members. A hypothetical illustrative example is solved and computed by MS Excel's add-in Evolutionary Solver, which uses genetic algorithms as a powerful spreadsheet tool. The model is a good example of the synergistic area consisting of social psychology, operations research, organizational behavior and human resources management.
