In order to solve problems of imperfect functions, high coupling degree, poor stability and high maintenance and use cost of traditional supplier management system for industry and mine enterprises, a supplier collaboration management platform was proposed which was based on Silverlight and model-view-view model. The platform structure, design schemes of main function modules and platform implementation based on model-view-view model were introduced in details. Application shows that the platform runs well, effectively reduces use cost and improves management efficiency.
