The values of perishable products decay as time passes.If the total costs can be allocated fairly or stably among customers,there is an incentive to cooperate for different customers.Considering the transportation cost and decay value,the cost allocation problem is formulated as a transportation facility choice game.It is proved that the choice game has a non-empty core and also concave in case of negative exponential decay function.The characteristics of some solutions are analyzed.It is shown ...
