Fuzzy Continuous Resource Allocation Mechanisms in Workflow Management Systems

In this paper, an approach based on a fuzzy hybrid Petri net model is proposed to solve the resource allocation problem of workflow management systems. Hybrid resource allocation mechanisms are modeled by hybrid Petri net with discrete transitions where discrete resources represent equipment and continuous resources represent employees availability. To express in a more realistic way the resource allocation mechanisms when human behavior is considered, fuzzy sets delimited by possibility distributions of the triangular form are associated with the marking of the places which represent human availability. New firing rules and the fuzzy marking evolution of the new model are defined. Such a fuzzy resource allocation model is applied to an example of resource allocation mechanism of a "handle complaint process"
