be inserted into the buyer and seller, such as factory, warehouse, vendor, and financial department.
Through the above two methods, the user can design any complicated SCM according to their need.

In the shipbuilding enterprise, the effective method in SCM is to purchase the steel, paint, marine
apparatus and other materials according to the production schedule in the global market, and then
reach the goal of purchasing under request, zero inventory and speeding the production. Based on
HASS commerce model, we design an agent based SCM in shipyard. (See the Figure 2) The whole
supply chain consists of user, an intermediary supply department and seller. The user represents
different department in shipyard, such as design, engineering analysis, manufacturing, finance and
other departments. The supply section represents various users, purchases on behalf on various needs.
The seller is the suppler who can provide shipyard with the need product. They locate in worldwide.
The whole enterprise activity consists of two flow, purchasing and fulfillment.
As shown in Figure 2, the commerce model is expanded to meet our need. For example, B1, B2 is
divided into a series of activities, exchanges among the use, supply and seller. Such as market survey,
complete PR form, research resource. Among, exchange internal to the organization is represented
with X2’, X5’. At the same time, the buying activity is divided and extended to the following activities
(analyze the price, select resource, sign the order and receive product and make payment)

4 PROTOTYPE
Mobile Java agent -1BM Aglet is selected in our prototype of SCM, since the suppliers in shipbuilding
SCM are located worldwide, and in current network band, the mobile agent can keep the data
integration and security, combined with other characteristics, it can meet the need of agility of
enterprise121’. Moreover, IBM Aglet is free to use according the license.
