• The logistical supply and physical distribution of goods now takes place in an age of rapid change. Systematic methods are necessary that can be used to analyze logistics and physical distribution in Japan in such an age. Thus, a national network of logistical and physical distribution routes for all of Japan is prepared focusing on unit loads of cargo such as trucks, chassis, and containers. Demand analysis and forecasting techniques are also developed for ferry and RORO ship sea routes using a sacrifice model. (Most units of cargo are transported on the route with the minimum sacrifice, which combines cost, time required and other factors together.) These demand analysis and forecasting techniques are then used to determine the demand for a sea route when given the conditions of the route (freight rate, speed, and number of services), for the purpose of designing ships with the capacity to cover this demand, and to develop methods to determine the profit that could be realized from operating these ships on the route. Several sea route conditions are considered, parameters are set, and cases ordered according to profitability and feasibility, which enables the managers of the shipping company to determine the most optimal sea route conditions and principal particulars of the ship, etc. based on the results obtained. These methods have been incorporated in serial and separate programs that make it possible to use these methods and related information to optimize existing sea routes when replacing ships, to determine the profitability of new sea routes, and to investigate the conditions of modal shifts from land to sea routes, amongst other things. These methods and programs are also useful in providing useful solutions for shipyards, shipping companies, banking and financial institutions, investors, government administrations, and others with an interest in the results obtained.
