This paper presents the results of an academia-industry collaborative project whose main objective was to test novel techniques for the development of event-driven control systems in the batch processing (e.g., pharmaceutical, fine chemicals, food) industries. Proposed techniques build upon industrial standards and focus on (i) formal synthesis of phase control logic and its automatic translation into procedural code, and (ii) verification of the complete discrete-event control system via dynamic simulation. In order to test the techniques in an engineering environment, a complete discrete-event control system was produced for a benchmark batch process plant based on a standard development method employed by one of the industrial partners. The control system includes functional process specification, control architecture, distributed control system (DCS) proprietary programming code for procedural control at equipment, unit, and process cell levels, and human-machine interfaces: A technical assessment of the development method and the obtained control system was then carried out. Improvements were suggested using the proposed techniques in the specification, code generation and, verification steps. The project assessed the impact of these techniques from both an engineering and economic point of view. Results suggest that the introduction of computer aided engineering (CAE) practices based on the benchmarked techniques and a structured approach could effect a 75% reduction of errors produced in the development process. This translates into estimated overall savings of 7% for green-field projects. Figures were compared with other partners' experience. It is expected that the work load on a given project will shift, increasing the load on process engineers during the specification stage and decreasing the load on the software engineers during the code writing. 相似文献

Although there is a vast array of quality literature available on generic project management, control room design and human machine interface design, there is very little material that discusses the methodology involved in replacing an existing system. The author looks at the potential value of evaluating a control system replacement, and presents a case study of such a project 相似文献

This paper describes a case study of a control system design for a batch pharmaceutical process. The ISA standard S88.01 batch control models and terminology were used as the main guidelines for the implementation. As the S88 is not a guide for how to apply the definitions/structures, etc., one of the main goals of our work was to create a methodology for decomposition of functional requirements in terms of S88 models and structures. This methodology was tested on a real problem, described in the case study. Also presented are some remarks on project methodology and Food and Drug Administration validation. 相似文献
