Application Of Ant Colony Algorithm And Grey Relation Theory In Selecting Cooperative Manufacturing Partner

According to requirement of cooperative manufacturing partner selection based on networked manufacturing environment, the paper resolves cooperative manufacturing partner selection problem by ant colony algorithm and grey relation theory: Firstly, manufacturing task is divided into series of working procedure in time order by technologic planning. Secondly, considerable candidate enterprises are selected in terms of multi-hierarchy grey relation coefficient at each working procedure node to reduce the size of problem. Lastly, cooperative enterprise selecting path is decided by making use of ant colony algorithm in light of transportation cost.
