An optimization model for the control of complex turnkey projects in plant engineering

Turnkey plant projects are endeavors which are characterized by high complexity and system dynamics. The application of special methods and models in the project management processes of planning and monitoring & controlling has become a competitive advantage in turnkey plant business. Special attention has to be given to the identification and evaluation of changes and disturbances as those could have severe impacts on the project`s objectives. The selection and implementation of proper control measures becomes crucial to ensure successful projects. In this paper a novel approach for modeling the interdependencies of engineering activities is presented. The approach particularly addresses planning information and changes that will limit the effects of control measures in the case of possible delays. The modeling approach offers decision support by providing a holistic basis for the evaluation of changes.
