要約(日本語): In recent years, sea and air transport has become a big trend. Getting an optimal solution with minimum costs (freight cost, warehouse cost) under certain constraints (delivery due date etc.) must be sought. Formerly, Takeyasu et al. made a mathematical formulation of the case of a single supply site and a single demand site with multiple delivery dates/different delivery quantities as a fundamental one. Under certain constraints, a minimum costs was pursued. In this paper, the objective function is expanded from considering transportation costs to considering transportation costs and warehouse stock fees. Here, a reduced cost is taken into consideration according to the shortened days to the delivery due date. Expansion is executed as for the case of a single supply site and multiple demand sites. A simple numerical example is examined and an optimal solution is derived using genetic algorithm. By formulating a sea and air transport problem, it can be handled clearly and smoothly.
