The minimal cost-benefit ratio and maximal benefit-cost ratio

This paper deals with computing the minimal and maximal shares of individuals or organizations based on different criteria. Suppose that players are selfish. Each player makes any possible efforts to bring about his or her ideal condition. This paper introduces the models for computing minimal cost-benefit ratio and maximal benefit-cost ratio, for each player and their coalitions and provides a new scheme for avoiding zero weight occurrence in these models. By using these models successful players or coalitions can be obtained.
