In this paper, we describe the Barrel Allocator, a s c heduling tool developed for day-today allocation and management of airlift and tanker resources at the USAF Air Mobility Command AMC. The system utilizes an incremental and conngurable constraint-based search framework to provide a range of automated and semi-automated scheduling capabilities, including(More)
Efficient allocation of aircraft and aircrews to transportation missions is an important priority at the USAF Air Mobility Command (AMC), where airlift demand must increasingly be met with less capacity and at lower cost. In addition to presenting a formidable optimization problem, the AMC resource management problem is complicated by the fact that it is(More)
This paper discusses work aimed at accelerating the construction and introduction of planning and scheduling systems in complex application domains. We begin by outlining our basic perspective on planning and scheduling, and our assumptions about the requirements and characteristics of practical planning and scheduling problems. This leads to a particular(More)

In this report, we examine the workflow management process from a scheduling perspective. Recognizing that effective work-flow management requires an ability to efficiently allocate limited resources to tasks over time, we concentrate on characterizing this domain as a continuous distributed scheduling problem and on understanding the requirements and(More)
In this paper, we consider the use of ontologies as a basis for structuring and simplifying the process of constructing domain-speciic problem-solving tools. We focus speciically on the task of scheduling. Though there is commonality in scheduling system requirements and design at several levels across application domains, diier-ent scheduling environments(More)
