A collaborative network is a network consisting of a variety of autonomous actors (e.g. enterprises, organizations and people) that collaborate to better achieve common or compatible goals. A collaborative network starts with a contract and then the collaboration partners conduct business as described in the contract. Before engaging in such a collaboration, partners need to reach an agreement regarding their responsibilities in the collaboration and develop a shared understanding regarding the endurability and the profitability of the collaboration. Here in this paper, we aim at analysing the endurability of collaborative networks based on the trust relations between collaboration partners and also introducing a new approach to do profitability analysis for collaborative networks. Therefore, we enrich the value models of business collaborations with information about trust, endurability and profitability.
