A Maintenance Demand Analyzer - a Web Service based on a Semantic Plant Model

Modern production plants need novel information and knowledge management approaches and services to support operation and maintenance decision making. With existing solutions, information is at best exposed in a structurally interoperable form but with lacking semantics. Application of semantic web ontologies could provide better means to exploit information in existing information systems. A semantic plant model is a semantically rich representation about a plant that can be accessed by value added services. A particular service, maintenance demand analyzer, gathers individual analyses that are based on various criteria and originated from several systems to produce a maintenance recommendation for devices in specific processes.
