A conditional constraint satisfaction problem (CCSP) extends a standard constraint satisfaction problem (CPS) with a conditionbased component that controls what variables participate in problem solutions. CCSPs adequately represent configuration and design problems in which selected subsets of variables, rather than the entire variable set, are relevant to(More)
Model debugging is an important component of assisting modelers with constraint-based problem formulation. This paper is built around a case study in modeling a special class of CSPs, which represent problems that change when certain conditions are met (Mittal & Falkenhainer 1990). The control of changing the problem, by activating or deactivating(More)
Distributed software problems can be particularly mystifying to diagnose, for both system users and system administrators. Model-based diagnosis methods that have been more commonly applied to physical systems can be brought to bear on such software systems. A prototype system has been developed for diagnosing problems in software that controls computer(More)
There is no standard model at the service layer. However, fault management to distributed services and applications needs to construct and utilize complex models of the participating objects and their interdependencies, Thus, model-based fault management tools can predict the correct behavior of diagnosed systems and use the resulting predictions to(More)
Today's network management applications mainly collect and display information, while providing limited information processing and problem-solving capabilities. A number of diierent knowledge-based approaches have been proposed to correct this deeciency, evolving from rule-based systems through case-based systems, to more recent model-based systems. Part of(More)
Online presence of information and services is pervasive. Teaching and learning are no exception. Courseware management systems play an important role in enhancing instructional delivery for either traditional day, full-time students or non-traditional evening, party-time adult learners enrolled in online programs. While online course management tools are(More)

Telephone triage, or telephone advice counseling, is becoming a key managed care point-of-entry tool for patients and health plan members accessing the health system. Telephone triage functions as a logical front-end for health plans, integrated physician groups, or integrated delivery systems that want to shift their managed care efforts toward demand(More)
Information Technology (IT) curricula's strong application component and its focus on user centeredness and team work require that students experience directly real-world projects for real users of IT solutions. Although the merit of this IT educational tenet is universally recognized, delivering collaborative and experiential learning has its challenges. (More)
At the direction of the ACM Education Board, the IT2017 Task Group was formed with the charge of updating the joint ACM and IEEE Computer Society Curriculum Guidelines for Undergraduate Degree Programs in Information Technology, known as IT2008. The revised document, called IT2017, should be appropriately forward looking given the significant advances in(More)
