This paper presents the prototype of an advanced platform for production analysis and optimization, referred to as ProOpter. The platform was developed to support the recently derived concept of holistic production control (HPC), which relies on model-based control. The prototype is comprised of a set of off-line and on-line modules. The off-line modules support the definition of key performance indicators...
The specifics of process manufacturing have a great influence on production management, and the focus of process-production control is to maintain stable and cost-effective production within given constraints. The synthesis of production-control structures is thus recognized as one of the most important design problems in process-production management. This paper proposes a closed-loop control structure...
The synthesis of plant-wide control structures is recognized as one of the most important production- management design problems in the process industries. This article proposes a decision support system, utilizing key performance indicators (pPIs) as a possible solution to simplify this problem. pPIs represent the translation of operating objectives, such as the minimization of production costs,...
This paper describes a control logic implementation approach, which is based on discrete event models in form of finite state machines and Petri nets. Such models may be derived during supervisory control synthesis. The approach defines a transformation of the models into an IEC 61131-3 compliant code that can be translated and downloaded into a standard industrial programmable logic controller. This...
