Application of logistics is now urgently required among Japanese enterprises, which are preoccupied with various problems to be solved in the area of physical distribution.
These problems stem from the enterprises aiming that physical distribution ought to be the 3rd source of corporate profit. This belief is rooted in the physical distribution stucture in the Showa 40's, and the enterprises should get rid of the purposes mentioned above.
To overcome the situation affected by the above purposes, the introduction of concepts such as “Strategic development of customer service” “Structuring of integrated system among related departments” and “Structuring of integrated system among companies concerned” is particularly needed and indispensable.

Now Techo-Super-Liner (TSL) is researched, in a movement of modal-shift. Its speed is intermediate between airplane and autotruck. It will change the system of physical distribution. Feasibility studies are testing in many cities. The most important point of a feasibility study is forecasting a demand of TSL precisely. In this paper, we try to make a model for forecasting a demand of TSL. Up to now, a model split model for physical distribution has been made with marco data only. We can't make a modal split model for TSL by the former method. So we try to make it by AHP.
First we investigate TSL specification, and review the former modal split model for physical distribution. Next we indicate the characteristic of it, and select suitable goods for TSL. Consequently we extract eight goods for making a model. We get informations and data to make a model from a hearing with shippers and others. So we use 5 items for evaluation standared : cost, speed, lot size, operation schedule and unit load. Under Hierarchy chart, we compute weights of evaluation standards and evaluation scores.
Finally we get logistic curve between modal split rates and evaluation scores. We compute a modal split rate of TSL and a demand with this curve. So we indicate a validity of this method.

The EDI (Electoronic Data Interchage) systems have been already applied to many problems in industries like banking trade. But, in the field of logistics, the applications of EDI systems have not been fully utilized as yet.
Since many problems has been, on the hand, produced in the relation to the heavy load of daily logistics operations which has been produced as a by-product of the innovation of information technology and minimum inventory policy. The consensus on the importance of LOGISTICS-STANDARDS has been formed in EIAJ (Electronic-Industries Association of Japan) and many other industries.
An unsolved problem is as ffollws
“How can we accomplish the COST-MINIMUM from suppliers to purchasers?”
The most important is, that, if purchasers, suppliers and transporters would alter the present selfish standpoint of view, the present social disadvantage could be reduced. We should understand more about daily logistics operations among them and should compromise each other as much as possible.
This paper is a result of many trials to find out some common ground based on EDI systems.
The proposal made in this paper would be taken up as a definite plan to get the social consensus.
