Multi-Disciplinary Engineering (MDEng) environments involve a wide range of models, processes and tools that were not designed to cooperate together. The Ontology-Based Information Integration (OBII) approach has been proposed to address the integration issue within such environments. However, knowledge changes management and analysis (KCMA) process within the environment are not covered within the OBII approach. While the traditional ontology change management approach has been investigated to

... the general problem, it remains unclear how to use the available solutions within MDEng context. In this paper, we extend the OBII approach to enable the KCMA process. We have identified the main KCMA requirements within MDEng projects and studied the related work of Ontology Change Management to propose a suitable solution, as well as suggesting further works.
