Research on contract net schedule algorithm based on medium pattern

Contract net schedule algorithm based on medium pattern was proposed. In this algorithm, manager provides information service for contractor and task agent as medium during releasing contract. Contractor and task agent evaluate each other according to its evaluation function and then select the suitable object. Compared with traditional contract net, the algorithm in which task is regarded as agent reduces the communication and load between manager and contractor. Besides, task executing time is cut down. At last, taking the production schedule for example verifies this algorithm. Tests showed that amount of communication in manager is less and the task is assigned more effectively by the contract net schedule algorithm based on medium pattern.
