Coordination in collaborative environments - a global approach

Abstract

I n this work we presenr a methodology lo express both analytically and graphically the interdependencies among tasks realized in a collaborative environment. For each interdependency expression, a coordination mechanism is built, modeling the global behavior of the environment, i.e., the structure that ensures the realization of the tasks according lo the establhhed interdependencies.

Petri Net-based Coordination Component for Collaborative Design

“…Experience tells us that most tasks are interdependent. Interdependent tasks are divided into two types: temporal and resource dependencies [11,12].…”

Graph Theory-based Logic Relationship Programming of Product Development Process

“…Raposo, Magalhaes, Ricarte, and Fuks made some improvements to Allen's basic relations by adding a couple of new relations and making some variations of those originally proposed [4]. Da Cruz, Raposo, and Magalhaes used seven basic relations of Allen to develop a logic relation graph of tasks and proposed two properties of relation graph [5]. Li, Liu, and Guo defined the concept of process template and classified the logic relations of processes into five categories, i.e., before, meet, start, equal, and finish [6].…”

“…Kusiak used graph theory as a tool to develop a dependency network for design variables and analyzed the dependencies between design variables and goals [9]. Da Cruz, Raposo, and Magalhaes presented a methodology to analytically and graphically express the interdependencies among tasks realized in a collaborative environment [5]. Durai Prabhakaran, Babu, and Agrawal took the advantages of the graph theoretic approach to considering all the design aspects together in a single methodology with the help of matrix algebra and permanents [10].…”
