This paper is concerned about design and implementation of a real time yard management system which can efficiently fill up a gap between transportation and warehouse management system in supply chain management. It is difficult to implement an optimal operation method through mathematical programming because of the dynamic complexity of real time yard management system. Therefore, we apply a workflow system, which describes the automation of internal business operations, tasks and transactions that simplify and streamline current business processes, to a real time yard management. In the beginning, we design a large number of workflow patterns in yard management, via worklist mechanism. Then, that is implemented by YAWL which is known as one among workflow specification languages. The proposed design and implementation can improve performance measures of yard management system through dynamically pertinent control.
