In this paper we consider the problem of grouping machine and human resources in mixed model assembly process so that sequencing and scheduling decisions may be performed more efficiently. Resource aggregation can potentially and significantly improve production efficiency and throughput by...

In this paper, Statistical Activity Cost Analysis (SACA) is used to identify the interaction of mutually dependent physical and financial aspects of a fixed asset-like system configuration. The novelty of the approach is, having established a rational description of the uncertainty inherent in...

In some manufacturing situations, station tasks or operations can be shifted or redistributed to adjacent stations when adjacent stations have the appropriate equipment and the workers on that station can perform the shifted work to a reasonable level of competency. This paper addresses such an...

Electric utilities in Australia have been developing policies to stimulate interest and permit the purchase of electricity generated by renewable energy sources such as photovoltaic systems (PV). Studies show that under current conditions, it is technically feasible to introduce small-scale,...

In this technical note we discuss a paper of Benkherouf and Balkhi recently published in Mathematical Methods of Operations Research. They established the model for deteriorating items with increasing demand and proved the uniqueness for the solution of the system of first partial derivatives....

Operations Research / Management Science (OR/MS) can be described as the discipline of applying advanced analytical methods to help making better decisions and has been around in the agricultural and forestry management sectors since the fifties, approaching decision problems that range from...

In this technical note, we consider the optimal replenishment strategies for a continuous review inventory model in which temporary price discounts are offered subject to supplier-obligatory restrictions on the special order quantity. We prove that the minimum inventory level during the on-sale...

Demerits control is the traditional tool for monitoring defects of different severity with a single chart. It requires arbitrary assignment of numerical values to the ordinal scale and therefore is theoretically flawed. We assess the error rates of demerits control compared to an alternative...
