Abstract:
The purpose of Workflow Management Systems is to execute Workflow processes. Workflow processes represent
the sequence of activities that have to be executed within an organization to treat specific cases and to
reach a well-defined goal. Therefore, it is to manage in the best possible way time and resources. The proposal
of this work is to express in a more realistic way the resource allocation mechanisms when human behavior is
considered in Workflow activities. In order to accomplish this, fuzzy sets delimited by possibility distributions
will be associated with the Petri net models that represent human type resource allocation mechanisms. Additionally,
the duration of activities that appear on the routes (control structure) of the Workflow process, will be
represented by fuzzy time intervals produced through a kind of constraint propagation mechanism. New firing
rules based on a joint possibility distribution will then be defined.
