Knowledge management exchange schemes based on symmetric incentives are rarely found in the literature. The distributed knowledge model relies upon a double loop knowledge conversion decision support system with symmetric incentives in an extranet. The model merges specific knowledge with knowledge from other actors into a decision support system specific for each actor in the network in recognition of actor role differences. The article analyses the conditions for the model to generate symmetric incentives between different actor roles. The model is proposed for business networks like supply chains and networks like replacement, maintenance and services industries.
