Abbott curves characteristics of turned surfaces
(2003)Evaluation and modelling of bearing curves and bearing ratio parameters are of great importance in surface characterization and tribological functioning of engineering surfaces. The present investigation is focused upon ... -
Application of Taguchi design for quality characterization of abrasive water jet machining of TRIP sheet steels
(2012)In the present paper, the influence of sheet thickness, nozzle diameter, standoff distance, and traverse speed during abrasive water jet machining (AWJM) of transformation-induced plasticity (TRIP) sheet steels on surface ... -
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 ... -
The berth allocation problem with stochastic vessel handling times
(2013)In this paper, the berth allocation problem with stochastic vessel handling times is formulated as a bi-objective problem. To solve the resulting problem, an evolutionary algorithm-based heuristic and a simulation-based ... -
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, ... -
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 ... -
A new model to mitigating random disruption risks of facility and transportation in supply chain network design
(2014)In this article, we study the design problem of a reliable stochastic supply chain network in the presence of random disruptions in the location of distribution centers (DCs) and the transportation modes. It is assumed ... -
A note on preemptive scheduling of multiclass jobs with geometric service times and hard deadlines
(2013)We consider the scheduling of multiclass jobs with deadlines to the completion of their service. Deadlines are deterministic and job arrivals in each class occur at the times of deadline expirations in the respective class. ... -
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 ... -
Pin-assisted resin infiltration of porous substrates
(2015)We analyze computationally the process of pin-assisted resin infiltration of porous substrates. In such a process, a porous substrate is pulled over a staggered array of stationary pins. A wedge-shaped fluid region forms ... -
Production capacity modeling of alternative, nonidentical, flexible machines
(2002)Analyzing the production capacity of a flexible manufacturing system consisting of a number of alternative, nonidentical, flexible machines, where each machine is capable of producing several different part types simultaneously ... -
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 ... -
Thermochemical treatments for protection of steels in chemically aggressive atmospheres at high temperatures
(1999)Boronizing is a well-known thermochemical treatment process that has found applications in a variety of industries. Boride layers on Fe-alloys present high hardness values (similar to 1900 Hv), good wear properties and are ... -
Thermomechanical Modeling of Laser Spot Welded Solar Absorbers
(2015)A finite element (FE) approach is developed to investigate the laser spot welding (LSW) of flat-plate solar absorbers and the stress and distortion fields that develop after fabrication and during operation. Numerical ... -
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 ...
