5 CONCLUSION
The paper researches the agent based supply chain management in shipbuilding industry, a general
commerce model is used to model and design the supply chain management, and implement a
prototype of SCM. From the above, mobile agent based supply chain can reduce the cost, inventory,
shorten the production period, and finally reach the agile manufacturing. From our implementation, the
