Time Management Model of Workflow Based on Time Axis

The goal of workflow system is to guarantee that the right activities are executed and completed within the correct and ideal time periods via automation, moreover, in order to help a company to be sufficiently competitive, the workflow system it adopts should be able to ensure activities are carried out to the maximum extent as possible and to manage several workflow instances at the same time. Hence, sufficient consideration of temporal constraints and efficiency should be taken into the design process of workflow system. This paper proposes a model of workflow control based on time axis which is able to ensure one or more workflows to advance in correct time period efficiently and precisely.
