Abstract

Inter-enterprise collaboration has become essential for enterprise success. Competition between supply chains and networks of enterprises brings with it a need to participate in multiple collaborations simultaneously. We propose to increase the automation of the routine decision processes where possible, which reduces the cost and effort of collaboration establishment and management.

Inter-enterprise collaboration builds on trust. Relying on autonomous partner enterprises for a joint venture creates uncertainty and risks, which must be balanced by a willingness to collaborate despite the loss of control. Trust decisions are first made on establishing the collaboration to ensure an acceptable balance between the risks of the commitment and its benefits to the participant. In addition, measures are taken during the collaboration in order to keep this balance.

We define a trust management architecture where autonomous actors make automated, local trust decisions based on private policy. The decision-making process considers identified risks to assets as well as incentives, and learns from both first-hand and globally shared experience on the behaviour of business peers. While trust decisions help protect enterprise assets locally, a feedback loop through shared experiences also provides social pressure to respect contracts in the entire ecosystem. Trust decisions can be adjusted to different and changing business situations through policy configurations. Policy-defined routine decisions are automated, while others are passed to a human user. This system is a part of the Pilarcos collaboration management infrastructure, which includes services for partner discovery and interoperability checking, contract negotiation, breach detection and recovery.

Our contribution encompasses the information model, algorithm and process for making multi-dimensional trust decisions, aggregation algorithms for past experiences, and methods for adjusting the trust decisions. We have implemented the architecture and analyzed its properties, such as adjustability and attack resistance.

The results of this work can be utilized by the service provider enterprises through increased computational support for collaboration management, by operators in designing the infrastructure services, and to standardize best practices and create new collaboration patterns within business domains.
