CC-00-151 FIELDING A MULTIPLE STATE ESTIMATOR PLATFORM

Description:

Over the past few years the Abnormal Situation Management (ASM) Joint R&D Consortium has been involved in developing collaborative decision support technologies for improving abnormal situation management within the chemical industry. Within this collaborative decision support solution, an application called State Estimator (SE) provides diagnostic assessment of the current process state. State Estimators form the core of this decision support solution since they provide the first step in the overall decision making process. During the course of the past few years, the ASM Consortium has developed a set of analysis techniques and a methodology to provide this “process state” information accurately and reliably. Following a successful laboratory demonstration of a multiple state estimator platform (MSEP), the ASM Consortium developed their first field prototype in 1998. This prototype is currently being field-tested at three refinery sites. MSEP is possibly the largest industry-wide effort in developing and deploying a large-scale decision support system to manage abnormal situations. This paper is intended to give a summary of our experiences with developing and deploying such a platform in a large-scale chemical plant.
