This paper describes our ongoing work towards the implementation of an online Web Service Composition system, based on the most prevalent Web Service standards and utilizing other open source projects as sub-elements. The system will treat non-determinism as an inherent characteristic of the problem and will tackle it by exploiting AI planning technology, specifically contingency planning. The ...

Software process modeling and simulation hold out the promise of improving project planning and control. However, purely quantitative approaches require a very detailed understanding of the software project and process, including reliable and precise project data. Contemporary project management defines the success of project as a cube, rather than the traditional single point, which allows the...

Maintaining Public Order 1 at large events such as crowd demonstrations is a complex activity involving logistical and contingency planning and requiring shrewd management of strategies and tactics. Developing such skills can be assisted by computer based methods and a simulation system CACTUS was designed to achieve these objectives. It has several features of interest including a digitised ma...

ProAct is our planner for direct end-user use in project management and contingency planning. We’re building it after extensive experience with SIPE-2 (Wilkins, 1989) and discussions with Austin Tate and Brian Drabble. We rely on untrained end users to create the plan knowledge. Due to the nature of their planning needs, we’ve made several significant changes to the functionality and representa...

We present an approach that allows mission and contingency management to be achieved in a distributed and dynamic manner without any central control over multiple software modules. This approach comprises two key elements—a mission management subsystem and a Canonical Software Architecture (CSA) for a planning subsystem. The mission management subsystem works in conjunction with the planning su...

For Web service composition, choreography has recently received great attention and demonstrated a few key advantages over orchestration such as distributed control, fairness, data efficiency, and scalability. Automated design of choreography plans, especially distributed plans for multiple roles, is more complex and has not been studied before. Existing work requires manual generation assisted...

One of the main oil refineries in Turkey is located Izmit. This results a high volume crude and products handled Izmit ports. The region consequently at very risk for pollution. Due to destructive effects on various segments environment, comprehensive preventive measures crisis management related potential spill scenarios are necessary minimize contaminated areas. In this study, hydrodynamic da...

The persistence of communities along Louisiana’s coast, despite centuries of natural and technological hazard events, suggests an enduring resilience. This paper employs a comparative historical analysis to examine “inherent resilience,” i.e., practices that natural resource-dependent residents deploy to cope with disruptions and that are retained in their collective memory. The analysis classi...
