Abstract: The value of perishable products decaying when are transpor ted1.In this paper,the transport ation cost and decay value are considered,the costal location problem of perishable products is formulated as the cost allocation game for choosing transportation facility.It is proved that the cost allocation game has a non2empty core and also submodular at case of linear decay function.Some solutions as nucleolus,Shapley value,S-value are discussed.Lastly the cost allocation game with const raints is discussed,in which the core may be empty.Further research areas are presented.

Key words: perishable products, transportation facility, cost allocation game, submodular game
