Abstract Modern Engineering faces numerous, often antagonistic challenges: the fastest process design at manageable risks and minimum costs. BASF Corporate Engineering's answer is the development of the [email protected] to minimise total costs. It integrates shortcut equipment design and cost estimation directly into the process simulation environment. For the first time in commercial simulation software, all costs available at this project stage-variable costs as well as investment capital—are considered within the objective function for process optimisations. The result is an accelerated process design with improved starting points for an effective equipment design and efficient processes at minimised total costs.
