To improve the resource utilization of complex hardware /software systems,a fuzzy taskresource clustering model was proposed in response to real-time tasks,using the average distance to show the membership of fuzzy sets. The fuzzy similar coefficient was defined. In addition,the Resource Clustering Algorithm( RCA) was designed to cluster real-time tasks and historical tasks,and according to clustering results,the systems would analyze resources occupation and respond to real-time tasks rapidly. Through the ...
