Research of approval flow scheme based on consignation Agent model

In general traditional approval flow scheme,there were some problems need to be resolved.It was difficult to set up the complete approval flows and it was not appropriate for the highfrequency temporary varieties.To resolve these problems,we divided the complete approval flow into some components.and binded each segment with some consignation agent listeners.The latter project is responsible for processing the adjustment to the temporary variety.So segment with some listeners becomes the reusable approval control units and helps to strengthen the adaptability of approval flow.
