Backorder penalty cost coefficient "b": What could it be?
(2010)The classical economic order quantity (EOQ) model with planned penalized backorders (PB) relies on postulating a value for the backorder penalty cost coefficient, b, which is supposed to reflect the intangible adverse ... -
Comparative modelling of multi-stage production-inventory control policies with lot sizing
(2003)We propose a unified modelling framework, based on a queuing network representation, for describing, comparing and contrasting classical and new multi-stage production-inventory control policies with lot sizing. The classical ... -
Minimizing WIP inventory in reliable production lines
(2001)This work deals with the well-known buffer allocation problem in short reliable production lines. The objective is to find the optimal buffer allocation (OBA) that minimizes the average work-in-process (WIP) inventory, ... -
Numerical investigation of optimal policies for production flow control and set-up scheduling: lessons from two-part-type failure-prone FMSs
(1997)The optimal set-up change and production control policy for a failure-prone machine to meet constant demand rates for two part-types is obtained numerically. Computational experience is reported for several instances of ... -
Tradeoffs between base stock levels, numbers of kanbans, and planned supply lead times in production/inventory systems with advance demand information
(2005)We numerically investigate tradeoffs between near-optimal base stock levels, numbers of kanbans, and planned supply lead times in base stock policies and hybrid base stock/kanban policies with advance demand information ...
