The cost allocation problem is how to equitably and rationally distribute the common cost of the joint products or services that provide different benefits to each economic entity. These cost allocation problems have been dealt with in many fields such as highway facilities, airport runways and multipurpose dams. Most studies on cost allocation have been conducted on the application of cooperative game theory. Cooperative game theory consists of a set of players, called coalitions, and utility function for these coalitions and studies on the fair compromise (cost allocation) for the players. The cost allocation method such as proportional method, incremental method, nucleolus, Shapley value, and SOC are studied. Inventory games of EOQ(Economic Order Quantity) and EPQ(Economic Production Quantity) with shortages are described and a various allocation methods are applied to these inventory games. We examines through examples if the cost allocation methods satisfy the desirable properties of completeness, rationality, and marginality.
