Dynamic priority dispatching rules in job shops require the computation of all job priorities in a work center queue every time a machine in the work center becomes idle. This is extremely costly. Alternative priority update procedures are studied and comparative results in terms of performance...

In production scheduling, time performance is usually taken to be the province of sequencing models which take task processing times to be given. However, in practice, processing times can often be controlled by the choice of lot sizes which thus have a major impact on makespan, waiting times,...

A family of algorithms is described for finding optimum schedules for job-shops. The algorithms are of a branch and bound type but have a complete schedule associated with each node of the search tree. Branching from nodes is based on important conflicts in the schedule. Some results are provided.

This paper addresses a nonpreemptive single machine scheduling problem where all jobs have a common due date and have zero ready time. The scheduling objective is to minimize mean squared deviation (MSD) of job completion times about the due date. This nonregular measure of performance is...

This paper considers a bicriterion scheduling problem where a linear combination of two objective functions is considered, with weighting factors used to represent relative importance of the two criteria, i.e., total flowtime and range of lateness. A branch-and-bound solution procedure is...

This paper reassess modern day decision-making processes for healthier Asian economies by systematically unpacking and critiquing key assumptions that drive organisational communication and cultural systems in contemporary Asia. The term non-Western refers to interests of Asian economies and...

We examine the behavior of output disparities of Mexican regions relative to the richest region, the Capital, during the period 1940-2009, and the dynamics of the output gap series of the U.S.-Mexico border region. Our estimations suggest that whilst other Mexican regions have been catching up...

This publication contains recent baseline projections from the Arkansas Global Rice Economics Program (AGREP) for U.S. and international rice economies. These projections serve as a baseline for evaluating and comparing alternative macroeconomic, policy, weather, and technological scenarios....
