Complexity and workload considerations in product mix decisions under the theory of constraints

The literature on the product mix decision (or master production scheduling) under the Theory of Constraints (TOC), which was developed in the past two decades, has addressed this problem as a static operational decision. Consequently, the developed solution techniques do not consider the system's dynamism and the associated challenges arising from the complexity of operations during the implementation of master production schedules. This paper aims to address this gap by developing a new heuristic approach for master production scheduling under the TOC philosophy that considers the main operational factors that influence actual throughput after implementation of the detailed schedule. We examine the validity of the proposed heuristic by comparison to Integer Linear Programming and two heuristics in a wide range of scenarios using simulation modelling. Statistical analyses indicate that the new algorithm leads to significantly enhanced performance during implementation for problems with setup times. The findings show that the bottleneck identification approach in current methods in the TOC literature is not effective and accurate for complex operations in real‐world job shop systems. This study contributes to the literature on master production scheduling and product mix decisions by enhancing the likelihood of achieving anticipated throughput during the implementation of the detailed schedule. © 2015 Wiley Periodicals, Inc.

Synchronization in hub terminals with the circular arrangement problem

Hub terminals are important entities in modern distribution networks and exist for any transportation device, that is, cross docks and parcel distribution centers for trucks, container ports for ships, railway yards for trains, and hub airports for aircraft. In any of these hubs, the mid‐term planning task of synchronizing the transshipment of goods and passengers when servicing the transportation devices has to be solved, for which many different solution approaches specifically tailored to the respective application exist. We, however, take a unified view on synchronization in hubs and aim at a general building block. As a point of origin, a basic vertex ordering problem, the circular arrangement problem (CAP), is identified. We explain the relation between the CAP and hub processes, develop suited algorithms for solving the CAP, and extend the basic CAP by multiple additions, for example, arrival times, limited storage space, and multiple service points, make the problem adaptable to a wide range of hub terminals. © 2015 Wiley Periodicals, Inc.

Spies,advisors, and grunts: Film portrayals of counterinsurgency in Vietnam

Vietnam was a complex conflict, which historians and political scientists have struggled to understand. Some of the bitterest disputes in the historiography revolve around the US approach to counterinsurgency in Vietnam. Many different facets of the war have received the attention of filmmakers, and an examination of their work suggests new ways of thinking about the conflict. This article considers film portrayals of three phases of the Vietnam War – firstly, the early period of ‘political action’, then the advisory period, and finally the Americanization of the war after 1965. It suggests that by examining the experiences of participants in each of these phases, Vietnam War cinema helps to illustrate the problems that faced various American approaches to counterinsurgency in the conflict. Combined with the importance of films in determining popular perceptions of both historical conflicts and counterinsurgency in general, it suggests that they are worthy subjects of study and critique.
