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 ... -
Base stock versus WIP cap in single-stage make-to-stock production-inventory systems
(2002)A single-stage production-inventory system produces parts in a make-to-stock mode, and unsatisfied demand is backordered. The system operates under a so-called base stock with WIP cap replenishment policy, which works as ... -
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 ... -
Extended kanban control system: combining kanban and base stock
(2000)This paper introduces a new mechanism for the coordination of multi-stage manufacturing systems. This mechanism is called the Extended Kanban Control System (EKCS) and depends on two parameters per stage, the number of ... -
Fixed task zone chaining: worker coordination and zone design for inexpensive cross-training in serial CONWIP lines
(2012)This work introduces a new canonical model of worker cross-training, called a Fixed Task Zone Chain (FTZC), as a special type of zone-based cross-training and develops a methodology to employ it in U-shaped CONstant Work ... -

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, ... -
Modeling of surface finish in electro-discharge machining based upon statistical multi-parameter analysis
(2004)A multi-parameter analysis of surface finish imparted to Ck60 steel plates by electro-discharge machining (EDM) is presented. The interrelationship between surface texture parameters and process parameters is emphasized. ... -
Modelling of microsegregation and homogenization of 6061 extrudable Al-alloy
(2007)A simulation of the evolution of the as-cast microstructure during the homogenization heat treatment of A6061 aluminum alloy is presented. The microstructure is dendritic with phase and solute segregation. The alloy ... -
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 ... -
Optimal control of flexible servers in two tandem queues with operating costs
(2008)We consider two-stage tandem queuing systems with dedicated servers in each station and flexible servers that can serve in both stations. We assume exponential service times, linear holding costs, and operating costs ... -
A review on ergonomics of headgear: Thermal effects
(2015)The thermal effects related to wearing headgear are complex and different studies have investigated single parts of this topic. This review aims at summarizing the different findings to give a complete overview on this ... -
Science park, a high tech fantasy?: an analysis of the science parks of Greece
(2002)The literature on science parks evaluation mainly covers the developed countries of OECD. There is a lack of evidence about the role of science parks in the less developed countries. This paper aims to partially fill this ... -
Simulation of the transformation of iron intermetallics during homogenization of 6xxx series extrudable aluminum alloys
(2012)A computational simulation of the beta-AlFeSi to alpha-AlFeSi transformation has been performed in this work by integrating the process steps of solidification and homogenization. The composition profiles of alloying ... -
SINGLE VEHICLE ROUTING PROBLEMS WITH A PREDEFINED CUSTOMER ORDER, UNIFIED LOAD AND STOCHASTIC DISCRETE DEMANDS
(2013)We consider the problem of finding the optimal routing of a single vehicle that delivers K different products to N customers that are served according to a particular order. It is assumed that the demands of the customers ... -
The sustainable diffusion of renewable energy technologies as an example of an innovation-focused policy
(2005)Renewable energy technologies constitute a techno-economic system that is radically different from conventional systems, in terms of density, structure, regulatory and management practices. Consequently, their incorporation ... -
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 ...
