When the candidate contract satisfies the first request condition, the suitable contract selection unit 312 may determine whether the candidate contract satisfies the second request condition ( S220 ).

When the candidate contract satisfying the first request condition does not satisfy the second request condition, the suitable contract selector 312 excludes the candidate contract from the suitable contract (S240).

The suitable contract selection unit 312 selects the candidate contract as a suitable contract when the candidate contract that satisfies the first request condition meets the second request condition (S230), and the optimum contract selection unit selects the optimum contract You can perform the steps to select .

When the condition value input by the service requester includes n condition values, the suitable contract selector 312 determines whether the candidate contract satisfies the nth request condition n times, and if all are satisfied, the A candidate contract may be selected as a suitable contract (S230).

In the step of selecting the optimal contract (S200) in the optimal contract selection unit 313 according to an embodiment of the present invention, the optimal contract selection unit 313 is selected by the suitable contract selection unit 312 For a suitable contract, an optimal contract may be selected based on the priority input by the service requester when creating the matching contract.

For example, when the service requester inputs the first request condition as the first priority and the second request condition as the second priority, and there are a plurality of suitable contracts, selecting an optimal contract from among a plurality of suitable contracts To do this, you can perform the following steps:

The optimal contract selection unit 313 calculates a difference value between the condition value of the matching contract corresponding to the first priority and the proposed condition value of the suitable contract for each of the plurality of suitable contracts (S310), and the It may be determined whether a plurality of suitable contracts having the largest difference value exist ( S320 ).

When there is only one suitable contract having the largest difference value, the suitable contract having the largest difference value may be selected as the optimal contract ( S360 ).

When there are a plurality of suitable contracts with the largest difference value, the condition value of the matching contract corresponding to the second priority and the proposed condition value of the suitable contract for each of the plurality of suitable contracts with the largest difference value may calculate a difference value of ( S330 ), and determine whether a plurality of suitable contracts having the largest difference value of the second priority exist ( S340 ).

When there is only one suitable contract having the largest difference value of the second priority, the suitable contract having the largest difference value of the second priority may be selected as the optimal contract ( S360 ).

When there are a plurality of suitable contracts having the largest difference value of the second priority, a suitable contract having a faster timestamp parameter value of the suitable contract may be selected as the optimal contract ( S350 ).

When the number of suitable contracts having the largest difference value is one, the optimal contract may be selected (S11).

When the number of suitable contracts with the largest difference value is plural, the difference value between the condition value of the matching contract corresponding to the second priority input in advance and the proposed condition value of the proposed contract is obtained, and the difference value is the largest It can be determined whether the number of suitable contracts is one (S8).

When the number of suitable contracts having the largest difference value corresponding to the second priority is one, an optimal contract may be selected (S11).

When the number of suitable contracts with the largest difference value corresponding to the second priority is plural, the difference value between the condition value of the matching contract corresponding to the third priority input in advance and the proposed condition value of the proposed contract is obtained, , it may be determined whether the number of suitable contracts having the largest difference value is one (S9).

When the number of suitable contracts having the largest difference value corresponding to the third priority is one, the optimal contract may be selected (S11).

When the number of suitable contracts having the largest difference value corresponding to the third priority is plural, the timestamp value is compared to select a suitable contract having the earliest value (S10), and the timestamp value is the first A fast conforming contract can be selected as an optimal contract (S11).
