Case-based planning can take advantage of former problem-solving experiences by storing in a plan library previously generated plans that can be reused to solve similar planning problems in the future. Although comparative worst-case complexity analyses of plan generation and reuse techniques reveal that it is not possible to achieve provable efficiency gain of reuse over generation, we show th...

In partnership with the Aboriginal Health and Medical Research Council of NSW (AH&MRC), the NSW Ministry of Health is developing a 10-year Aboriginal Health Plan for NSW. Recent reports have highlighted the need for significant systemic and structural change, coupled with genuine engagement with Aboriginal people. A whole health-system approach has been adopted and is examining all the interdep...

Planning in Large Domains: The Markov decision process (MDP) formalism has emerged as a powerful representation for control and planning domains that are subject to stochastic effects. In particular, MDPs model situations in which an agent can exactly observe all relevant aspects of the world’s state but in which the effects of the agent’s actions are nondeterministic. Though the theory of MDPs...

Computer-supported treatment planning is an important task to support the medical staff in their daily routine. Several (semi-)formal languages to represent the medical treatment processes are available to support the treatment planning. Due to the complexity of most of these languages, assistance for developing the often very sophisticated processes is necessary. This paper defines a basis for...

This paper presents a process plan selection model with multiple objectives. The process plans for all parts should be selected under multiple objective environment as follows: (1) minimizing the sum of machine processing and material handling time of all the parts considering realistic shop factors such as production volume, processing time, machine capacity, and capacity of transfer device. (...

Abstract: This paper deals with the design of Optimal Step-Stress Partially Accelerated Degradation Test (PADT) using Wiener Process for modelling degradation paths. In partial step-stress loading, the unit is tested at usual stress for some time and then stress is accelerated. This helps in preventing over-stressing the test specimens. Failure occurs when the performance characteristic crosses...

Determining the most appropriate means of producing a given product, i.e., which manufacturing and assembly tasks need to be performed in which order and how, is termed process planning. In process planning, abstract manufacturing tasks in a process recipe are matched to available manufacturing resources, e.g., CNC machines and robots, to give an executable process plan. A process plan controll...

The use of mobile ad hoc networks (manets) and of adaptive process management systems, able (i) to enact cooperative processes among the on-the-field operators and (ii) to cope with disconnection anomalies, is an effective tool in emergency management. In this paper, we present the architecture of MOBIDIS, a novel manet-based process management system for emergencies, and we describe the novel ...

We have developed a domain-independent systematic methodology for plan merging at the various levels of plan abstraction. This method manifests itself in the hierarchical plan graph where each level contains a complete, partially merged plan. The principle advantage of this approach is that, once external interactions between nodes on a given level have been established, the continued merging o...

Contour Crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The Contour Crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for Contour Crafting benefit the technology by increasin...
