Session Report: Supply Chain Dynamics: asking & answering continuing after session

This parallel session was chaired by Prof. Khalid Saeed, who was also one of the speakers in this session. The parallel was taken in Seaport A, 1st of August, 2007. It’s composed of 3 presentations, respectively by Margherita Pero, from Italy, Lizhen Huang, from Fuzhou University, China and Prof. Saeed, from Worcester Polytechnic Institute, US. The parallel went very smoothly.

However, different from other parallels, in this session, the chairman Prof. Saeed suggested the audience save all their questions until all the speakers finished their presentations. The reason for this is the close relationship that the three papers had. A lot of time was saved by doing this and made it possible for the audience to think more widely.

The first speaker, Margherita Pero, talked on the topic of Supply network design and collaboration: a preliminary study. Supply chain network design, i.e. sourcing strategy, number of network stage and node’s capacity and localization, was the main focus of her presentation. Experimental runs based on System Dynamics modeling were compared with each other in order to find out the effect of supply chain network design, when taken into consideration.

The second speaker, Lizhen Huang, gave a speech on the topic of The bullwhip effect in the closed loop supply chain. Lizhen cut into the topic by studying remanufacturing in a closed loop supply chain. She had two most important findings, both of them about bullwhip effect in a closed/open loop supply chain and inventory variance when remanufacturing was introduced to the loop.

The last speaker, Prof. Saeed talked about trend forecasting as derivative control. As indicated in the topic, his focus was trend forecasting in driving policy in social systems and derivative control in classical control theory. Prof. Saeed compared these two processes and made very careful analysis during his presentation. Two pictures respectively for each process were taken during the speech, as shown in the following.

After the presentations, it’s finally question time, when the audience couldn’t wait to ask their questions. The person with questions asked all the speakers one by one, and the speakers all stood in front ready to answer any questions for them, as shown in the picture on the right.

It’s a heated asking & answering between speakers and audience, which both parties were glad to take part in. The asking & answering continued after the session…

Who can reject the session was a success?
