A Strategy to Minimize the Resource Conflict Duringa Work flow Execution Period

The resource conflict,cause from the multi-colleagues cooperation,is an unavoidable problem in workflow.In this paper we propose a detection model to minimize the resource conflict during the workflow execution.In such a model,all resources are regarded as objects of different types,different size.Some useful concepts are introduced into this model,such as spatial domain,occupation,overlapping,etc.It has the following advantages:(1) Strong applicability.Not only for bounded data space,and also suit to the objects such as image,speech,text,input and output devices.(2) Introduced a concept of spatial domain,and it may set smaller and smaller to an infinite small size,so the resource conflict may restricted to a very smaller domain.(3) Introduced the concept of overlapping and an attribute of duration to restrict spatial domain conflicts further.Based on such a model,we can distinguish no conflict and conflict occupation,and reduce the conflict as small as possible,at last to minimize the failed conflict in the procedure of workflow execution.
