This study compares how Canadian industrial engineers (IEs) and ergonomists 'position themselves' to influence human factors and ergonomics (HFE) issues. The study examined how these stakeholders perceived their influence on HFE issues, constraints they operated under, and strategies used. The...

The setting of time standards by work measurement is costly and consumes much time and effort. Therefore, the aims are to minimise time measurements while guaranteeing that the measurements are sufficient to provide a required statistical precision. This paper presents two methods for...

A modified median chart with estimated control limits is proposed for monitoring the mean value of a normal process. The estimates for the nominal process parameters used to set up the control limits in Phase I are the average of the sample medians and the average of the sample ranges of m...

This paper chooses a supply chain which involves multiple supply links as the studied object. In each supply link, we consider an integrated scheduling problem in which a set of identical jobs are first processed on a single machine, and then batch delivered to a customer by a transporter. Each...

The article proposes the development of an application methodology, named MARLIN, for logistics and transportation (L%T) scenarios analysis and comparison within the fresh food supply chain (FFSC). The MARLIN application methodology consists of the development of a dedicated simulation-based...

This article presents a straightforward production/inventory model that can capture the trade-offs among average inventory, production capacity and customer service levels in a semi-process industry setting. The model is based on well-known approximations from queuing literature, and it supports...

Simulation is an important tool to make design and operation decisions to enhance the performance of manufacturing processes and systems. The coordinated use of optimisation methods and simulation models can result in better decisions. This paper presents an optimisation via simulation (OvS)...

This paper develops scalable and effective yet simple heuristic methods for material assignment in a large discrete Build-To-Order (BTO) environment. The material assignment function allocates available supplies of raw material to orders over a period of time. Despite popular belief to the...

In the last few years, multivariate quality control has been thoroughly studied. The control of the population means vector is usually obtained by using multivariate control charts developed for this purpose. Nevertheless, when the goal is the efficient control of the covariance matrix, few...

Recognising the learning styles of today's upper level engineering undergraduates, a multimedia educational tool is developed to supplement traditional instruction in courses related to Materials Handling (MH) and facility design. The CD-ROM based system teaches design and analysis principles by...
