Shipbuilding Partners and Suppliers (SPARS) Consortium is established to deploy shipbuilding Supply
Chain Virtual Enterprise which will integrate the shipbuilding supply chain composed of customers,
partners, subcontractors, and suppliers. J.K.Lee1'61 used intelligent agent in the scheduling system for
shipbuilding In general, SCM in shipbuilding lags other industries, and has the following attributes[51.
0 SCM in shipbuilding is hampered by a lack of consensus on the structure, function and dynamics
of the integration of ship production and SCM.
0 Shipbuilding lags in the use of electronic commerce technologies.
0 Inaccurate production schedules affect many aspects of supply chain management, including
increased supplier costs, problems with timeliness and completeness of vendor-furnished
information, and diminished trust between the yard and its suppliers.
0 Although people begin to implement SCM in shipbuilding industry, but not all shipyards realized
its importance. Especially in China, no much focus even in the mind of manager of shipyard, the
relation between shipyards and their suppliers is more adversarial than necessary, not win-win.

3 MODELING THE AGENT BASED SUPPLY CHAIN MANAGEMENT

Since SCM involves a set of activities in and between enterprises. It is necessary and convenient to
analyze the process of SCM via a commerce model. This Commerce Model was originally developed
for one of the prototypical courses on electronic commerce at the Haas School of Business and pertains
to commerce in See the figure 1, it consists of buyer, intermediary, seller, and a series of
activities and interactions. The diagram depicts the process flow (from left to right) associated with a
commercial relationship or transaction, a transaction or relationship can be seen to progress through
each step along the process flow depicted in the model. Clearly these steps represent commerce at a
very high level

From the buyer's perspective, the process begins with the identification of some need and proceeds
through sourcing and purchasing to the use, maintenance and ultimate disposal of whatever product,
service or information is purchased. The seller's process begins with some arrangement to provide a
product, service or information (e.g., research and development, service process design, information
acquisition, etc.) and proceeds through marketing and sales to customer support. The arrows
connecting these high-level process steps are used to represent key items of exchange between buyer
and seller, items which constitute the commercial activity proper. For example, information is
exchanged at several points along the process flow, as are money and goods (or services, information,
etc.) and even "influence," as delineated at the negotiation stage. In the actual activity, each the higher
activity can be divided into sub-activity. For example, the fulfilling order can be divided into the
receiving order, notifying the shipping and logistics schedule and so on. Moreover, many activities can
