INFORMATION sharing, INSTRUCTIONAL systems, DISTANCE education, and EDUCATIONAL innovations
We are involved in the development of a time/knowledge exchange-based system. One of the objectives of the system is to improve the effectiveness of e-learning and distance education. The system envisioned is a chronobot-based system. In this chapter, we discuss the architecture of such a time/knowledge exchange based system. We propose a constraint satisfaction algorithm for time/knowledge exchange in order to solve the time/knowledge exchange problem, which interoperates with the various chronobots, coordinates the settlement of a bid in a distributed manner, and selects the best bid using a metric known as the QoB (Quality of Bid).

This paper evaluates the dynamic aspects of the UML in the context of inter-organizational workflows. Two evaluation methodologies are used. The first one is ontological and is based on the BWW (Bunge-Wand-Weber) models. The second validation is based on prototyping and consists of the development of a workflow management system in the aerospace industry. Both convergent and divergent results are found from the two validations. Possible enhancements to the UML formalism are suggested from the convergent results. On the other hand, the divergent results suggest the need for a contextual specification in the BWW models. [ABSTRACT FROM AUTHOR]
