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...

In this study, we use zero-one variables to control fixed transaction costs independent of trade size in the portfolio selection problem. The optimal solution to the maximum flow, risk constrained stochastic portfolio network is found using Digital Portfolio Theory (DPT). Digital signals...

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...

Today supply chains leverage their partner's competencies and in the process also inherit the risks associated with various links of a supply chain. Although it is impossible to completely eliminate various risks, an environment can be created which helps to effectively mitigate risk. The most...

When a batch of jobs are waiting for services from a machine or resource, sometimes it is desirable to minimise the variance of job waiting times Waiting Time Variance (WTV) for service stability to all the jobs in the batch so that the jobs have about the same waiting times. Many factors,...

Supply Chain Management (SCM) is a key strategic approach for increasing organisational effectiveness and the realisation of organisational goals. Effectively selecting and evaluating suppliers and managing their involvement in the supply chain are some of the capabilities that enable Original...

This paper considers the single machine scheduling problem with linear earliness and quadratic tardiness costs. The research on the version with an inserted idle time focused on an exact approach, while several heuristics were already proposed for the version with no idle time. These heuristics...

An optimal maintenance approach is a key support to industrial production in the contemporary process industry. This paper presents a Multiple-Criteria Decision Making (MCDM) methodology for selecting the optimal mix of maintenance approaches – Corrective Maintenance (CM), Time-Based...

Monte Carlo simulation provides a risk management tool for solving line layout problems when material flow requirements change over time and/or are uncertain. This study demonstrates this capability for line layout problems where material handling costs are not directly proportional to the...
