Prof Piplani is an Associate Professor with the School of Mechanical & Aerospace Engineering since December 1998. He received the Ph.D. degree in Industrial Engineering from Purdue University in 1995, and M. Eng. from Arizona State University in 1990. Dr Piplani is the director of M.Sc. (Supply Chain & Logistics). His research interests are in the area of inventory planning and network design of supply chains, and modeling of healthcare and production systems. He has worked on several funded research projects and was the program manager, Integrated Manufacturing and Service Systems (IMSS) for A*Star, managing the SGD 8 Million research program for four years.
Inventory planning and network design of supply chains, and modeling of healthcare and production systems.
|Supply-chain inventory planning|
In our latest research (in collaboration with a colleague from the business school) published in POMS journal, we have developed a new 2-bin policy for satisfying the demand from differentiated classes. In case of two demand classes, the policy has been shown to provide much higher service level to lower priority classes, at only a slight increase in system cost. An extension to this work (to multiple demand classes) has been completed and is ready for submission.

As buyers of capital-intensive systems have looked to contain costs of service and improve system availability, they are increasing turning to some sort of pay-for-performance contract. In our research we have developed models of performance for repairable inventory system operating under PBC, and have also studied such systems under changing fleet size.
