In order for a group of manufacturing SMEs to become competitive as a team, each of them should have its own strength and the strength must be united into an appealing process plan suitable for the specification of every manufacturing order. Since the detailed knowledge on the capability of each SME is owned only by the SME itself and often difficult to be disclosed to public, it is a big challenge how to properly incorporate the strength into the process plan without a single planner who knows the details of the capabilities of all SMEs. This paper calls this task as collaborative process planning, and proposes how to refine and utilize the platform of Route Market, which was originally developed by the authors for geographical route recommendation service, for the task.
