In this paper, the problem of lot sizing, scheduling and delivery of several items in a two-stage supply chain over a finite planning horizon is studied. Single supplier via a flexible flow line production system (FFL), produces several items and delivers them directly to an assembly facility. Based on basic period (BP) strategy, a new mixed zero-one nonlinear programming model has been develop...

      The objective of present research was to design, evaluate and compare drug release from two different dosage forms in pulsatile drug delivery system (DDS) for Metoprolol tartarate (MT) as tablet and capsule. Pulsatile systems are gaining a lot of interest as they deliver the drug at the right site of action at the right time and in the right amount, thus providing spatial and temporal del...

The integration of the Just-In-Time (JIT) system with supply chain management has been attracting more and more attention recently. Within the processes of the JIT system, the upstream manufacturer is required to deliver products using smaller delivery lot sizes, at a higher delivery frequency. For the upstream manufacturer who adopts sea transportation to deliver products, a collaborative thir...

In this research, we investigate a three-stage supply chain with one supplier, several manufacturers and multiple retailers where the supplier provides a common raw material to each manufacturer, who in turn uses a single stage production facility to convert it into final products that are delivered at fixed lot sizes to retailers. An integrated economic procurement, production, and delivery mo...

OBJECTIVE To evaluate the effectiveness of a rural clinical placement on students' self-perceived clinical skills and work location choice post-graduation. METHODS A one month rural placement program was introduced in 2008-2009 for 4(th) year dental undergraduates. Student's views on the rural exercise were collected by pre and post self-completion questionnaires, which were distributed to ru...
