Aiming at the issue of time consuming excess on single node during some workflow activities for the environmental parameters of standard chicken henhouse, this paper builds a P2P network node context based model on task allocating, scheduling and solving. Focusing on the dynamic characteristic of P2P network environment, the model adopts node context to describe the workflow environment. The workflow management system can obtain the environmental dynamic changes through perceiving context

... ation, and be used to manipulate task allocating and scheduling. Basing on the node context, this paper presents the node handling ability assessment index, with which the workflow management system can calculate out the price index and node task allocating index that equles to execution time and manipulate the task scheduling. Index Terms-Context, standard chicken henhouse, node model.
