TITLE: Operations Scheduling in Reverse Supply Chains: Identical Demand and Delivery Deadlines

SPEAKER: Dr. Gang Wang

BIRC Seminar Series

Dr. Gang Wang is an Assistant Professor in the Decision & Information Sciences Department at the Charlton College of Business. He earned his PhD in Supply Chain Management from Rutgers University. His current research of interest focuses on supply chain dynamics, supply chain operations planning and scheduling, supply chain sustainability, and supply chain finance as well as the modeling, theory and algorithm of optimal control problems over nonlinear hybrid dynamical systems.

He has published articles in referred journals such as International Journal of Production Economics, Annals of Operations Research, Computers & Industrial Engineering, Journal of the Operational Research Society, Journal of Process Control, Journal of Mathematical Analysis and Applications, Journal of Applied Mathematics and Computation, and Nonlinear Analysis: Hybrid Systems. 

Abstract: This study addresses an integrated operations scheduling problem in reverse supply chains, where delivery deadlines and identical demand are involved. The supply chains consist of contracted collectors, a manufacturer, and many secondary markets. Both collectors and manufacturer are capacitated. The manufacturer remanufactures returned/used products shipped from collectors and then ships finished products directly to geographically dispersed demand points in secondary markets, following order quantity and delivery due date that each demand point requests. It is assumed that each demand point orders the same quantity, which can be true in supply chain practices (i.e., grouping demand points into customer zones). Furthermore, the manufacturer is imposed penalties for late deliveries. The problem is to determine shipping quantities from collectors to the manufacturer and the assignment of collectors and demand points to the manufacturer, subject to the capacity constraints on both collectors and the manufacturer. This paper formulates the scheduling problem as a bi-criteria mixed integer program with the objective of minimizing both total shipping and penalty costs and delivery lateness. For the problem with the order size of one unit, the total unimodularity of its constraint matrix allows for the development of a polynomial time algorithm. The problem where order sizes are the same is solved by a dynamic programming based algorithm. The respective numerical examples are provided to verify the applicability of two problems and the effectiveness of their solution approaches.

TITLE : Big Data in Supply Chain Managment

SPEAKER : Dr. Petri Helo

Dr. Petri Helo is a Professor of Industrial Management, Logistics Systems and the head of Networked Value Systems research group, at Department of Production, University of Vaasa, Finland. His research addresses the management of logistics systems in supply demand networks and use of IT in operations.  Professor Helo is also partner and board member at Wapice Ltd, a software solution provider of sales configuration systems and mass customization solutions; Additionally, he is visiting professor at Kasetsart University in Thailand. Professor Helo has published numerous articles in well-known journals such as European Journal of Operational Research, Decision Support Systems, and Transportation Research: Section E. He has presented many papers at conferences around the globe. 

TOPIC: The availability of data from supply chains is giving new opportunities for supply chain management and performance measurement.Large quantities of real-time data streams, the big data, can give a view behind aggregated weekly or monthly performance numbers.Three case examples will be presented how companies can apply information systems in managing supply chains. The domains are

  • project logistics
  • analyzing customer orders
  • fleet management.

Finally, we will discusss how real-time data streams support the daily operations based on key performance measurements.

Time: 11:00am- 12:00am
