METHOD DEVELOPMENT
• MBE methodology General MBE methodology must be developed and documented. Important elements include identifying and defining common models (both descriptive and predictive) with the aim of avoiding duplication of work and increasing quality. Project manuals can be updated to clearly steer project work toward a model- based approach. Training efforts such as webinars for relevant staff are also necessary to establish the methodology. • Interoperability Interoperability can be defined as “the ability of different systems, often in computer contexts, to work together and be able to communicate with each other”. Important standards in the area are ISO 15926 and CFIHOS. The SEIIA organization conducts standardization work in Sweden, but there is a need for industry representatives to participate in the work to drive development in a direction that is appropriate for current operations. • Automatic/semiautomatic model generation There are several reasons to replace manual model generation with automatic or semiautomatic model generation. Risks of errors and deviations are reduced and a more consistent person-independent work process is obtained. Predictive models can, for example, be generated from intelligent P&ID schemas with linked descriptive models and data (i.e., ALIM systems and CAD models). This means that development focus and resources can be directed toward work with superior process functionality and not toward subordinate code generation. • Generation and updating of models Complex facilities and systems are constantly changing. New requirements and new technology mean that outdated and less suitable technical solutions and components are replaced. This means that connected models may need to be updated to accurately reflect the corresponding physical facility. Since this work can be resource intensive, methodology is needed to automate the process of creating, calibrating and integrating models in a real-time environment and keeping them current.
