Integrated modelling and decision support of continuous production systems

The benefits that integrated modelling can provide to asset managers of production systems are clear and well known. This work presents a framework for formulating integrated Mixed Integer Linear Programming (MILP) models of continuous production systems. The framework promotes the creation of generalised, reusable models and domain expert engagement to reduce the upfront modelling effort required to generate value; reducing the payback period of modelling investment. Methodologies for using the framework to deliver support for strategic, tactical and operational asset management decisions are presented. Emphasis is placed on translating the model results to corrective actions for managers to make system wide improvements. The learnings from applying the concepts to two continuous production systems—an open-pit coal mine and a building energy plant—are then discussed. Finally, avenues to further verify the value and extend utility of the contributions are offered.
