  Article:   OPERATIONAL SEMANTICS OF TASK MODELS.

Authors:  ADRIANA TARŢA, SIMONA MOTOGNA.
 
       
         
  Abstract:  This paper proposes an operational semantic approach for the task models. Task models are used in the process of user centered software design to represent the work structure and the sequence of steps needed to reach a goal. The goal of our approach is to develop inference rules which will reflect the changes on the presentation aspects of an application when a certain temporal operator occurs. By using the proposed inferece rule we will show that when the deductive process is ended the enabled task sets are determined.
