In this paper, we present methods for improving problems in group decision-making and implement a meeting scheduling system. This system automatically schedules meetings based on users' calendars. In the system, agents negotiate on behalf of the users. The problem is that the agent must clarify the trade-o between \reaching a consensus" and \re ecting the users' preferences." We improve the tra...

Work-conserving disciplines may be implemented with the use of scheduling calendars. Since calendars have finite resolutions, theoretical emission times that determine the positions of frames within the calendar slots have to be rounded to match the boundaries of the slots. The selection of a rounding method affects the performance of a work-conserving discipline. In this paper, we present an e...

The notion of time granularity comes into play in a variety of problems involving time representation and management in database applications, including temporal database design, temporal data conversion, temporal database inter-operability, temporal constraint reasoning, data mining, and time management in workflow systems. According to a commonly accepted view, any time granularity can be vie...

Time and calendars play an important role in databases, on the Semantic Web, as well as in mobile computing. Temporal data and calendars require (specific) modeling and processing tools. CaTTS is a type language for calendar definitions using which one can model and process temporal and calendric data. CaTTS is based on a “theory reasoning” approach for efficiency reasons. This article addresse...

Synchronisation of replicated shared data is a key issue in collaborative writing systems. Most existing synchronization tools are specific to a particular type of shared data, i.e. text files, calendars, XML files. Therefore, users must use different tools to maintain their different copies up-to-date. In this paper we propose a generic synchronization framework based on the operational transf...
