Analysis of chemical plant process safety information integration model from information system perspective

Abstract

Information with bearing on process safety can be mined from various work flows of a plant. This information is often found in reports, plant layouts and activity logbooks, which format is not structured. Hence, some information become obscured and tracking changes that compromise process safety become difficult. Whilst there are works to address access to unstructured sources, another following-up challenge is to compose information extracted from various sources meaningfully. This paper proposes a knowledge-based model to integrate safetyrelated information from multiple workflow sources to multiple sinks. The work provides an architectural perspective to improve visibility and interoperability of safety information within a plant environment.
