Cohesion and Granularity Applied in Task Decomposition Evaluation for Operations
Xiang Li · Electronics Optics & Control · 2012
To control the subdivision of task decomposition,a new method based on cohesion and granularity was proposed to evaluate the task decomposition for operations.First,the task association matrix was obtained based on input and output relationship between tasks.Then,the associated coefficient and reuse coefficient that have effect on task set were analyzed,a cohesion quantized model was established based on task associated matrix.Taking the task quantity and cohesion into account,the task granularity was selected as an important criterion to evaluate task decomposition,and a task granularity planning method was proposed.Finally,an example was given to show the effectiveness and feasibility of this method.The strategy can evaluate task decomposition scheme from task structure,quantity and cohesion.
