This paper presents a proposal for specifying task models for cooperative applications that allow designers to describe the relationships between the activities performed by various users involved in cooperative environments. To this end we extend the ConcurTaskTree notation so that new information useful for describing complex cooperative applications can be clearly specified. An example of ap...

The “conceptual graph” is a conventionally adopted assisted teaching method. Conceptual graphs display the achievements of students. This study proposes a novel learning activity called “Two-Phase Cooperative Learning.” The framework of this activity is based on the conceptual graph. The system includes the Dynamic Remedial Instruction Path (DRIP) and the grouping of cooperative learning phases...

Maintaining consistency of objects produced during cooperative software development activities is an important issue in the development process field. We propose a solution based on a specific transaction protocol which mixes a non-semantic and a semantic part. The non-semantic part is devoted to the correction of interactions between activities and the semantic part is devoted to the individua...

As pointed out by the literature, the recent growing interest in cooperative work studies is motivated by technological and organizational changes and by the design of computer systems for cooperative activity which requires models of human-human cooperation. The analysis of communications between group members is one of the powerful tools to identify and describe the functioning of cooperative...

Awareness of individual and group activities is critical to successful collaboration and is commonly supported in collaborative graphics design systems (CGDS). Awareness of cooperative efficiency visualized in fine granularity is valuable for finding out the bottlenecks in collaborative design process. However, little work has been done. In this paper we propose a novel intelligent cooperative ...

In the contemporary world, engineers and designers face huge challenges as they shift towards novel organizational concepts such as ‘concurrent engineering’ in order to manage increasing product diversity so as to satisfy customer demands while trying to accelerate the design process to deal with the competitive realities of a global market and decreasing product life cycles. In this environmen...

In this article the notion of relation work will be put forward to describe efforts of connecting people and artefacts in a multitude of ways as part of facilitating global interaction and coordination in an engineering firm. Relation work can be seen as a parallel to the concept of articulation work. Articulation work describes efforts of coordination necessary in cooperative work, but, arguab...

This chapter provides a practical and intuitive way of cooperative task planning and execution for complex robotic systems using multiple robots in automated manufacturing applications. In large-scale complex robotic systems, because individual robots can autonomously execute their tasks, robotic activities are viewed as discrete event-driven asynchronous, concurrent processes. Further, since r...
