The average transportation time of the first vehicle from each of the first candidate factories to the port of departure of the first country within the first country to which each of the first candidate factories belongs, and the second country within the second country to which the place of business belongs. Based on the average transport time of the second vehicle from the port of arrival to the place of business and the average transport time by sea between the port of departure and the port of arrival, determining the transport accessibility;
The contract suitability is calculated through the following equation,

In the above equation, D _s is the contract suitability, T _a is the transport accessibility, M is the monthly average production capacity of each of the first candidate factories, and C _r is the number of imports from the first country to the second country. The tariff rate applied when, K _a means the above risk,
The transportation accessibility is calculated through the following equation,

In the above equation, T _a is the transport accessibility, D _d is a straight-line distance between the user's place of business and each of the first candidate factories, a is the average transport time for the first vehicle, and b is the average transport time for the second vehicle. , c denotes the average transit time by sea, x is a weight for the average transit time for the first vehicle, y is a weight for the average transit time for the second vehicle, z is a weight for the average transit time for the sea, x , y and z are values greater than 0 and less than 1, where x is greater than y and y is greater than z, the factory intermediary platform provision system.
