Abstract: “Today simulation is playing an important role at multiple steps within the life-cycle of a process plant. For the future it is expected that simulation will be integrated in the plant life-cycle and the backbone of an integrated engineering process. To simulate the different aspects of a plant multiple domains are necessary. Usually each domain requires specific simulation capabilities, thus multiple specialized tools are used along the life-cycle. Reusing simulation models throughout the life-cycle would be very beneficial. This paper investigates existing approaches for model reuse and co-simulation and motivates the creation of a standard for co-simulation from a process industry perspective.”

Comments: the authors cite the book by B. BRAUNSCHWEIG and R. GANI when rightfully stating “The CO standard was developed for process simulation in the process industries, both stationary and dynamic”. However the book they cite covers many other points than just CAPE-OPEN. Only one chapter in the book is detailing CAPE-OPEN. Next they state, while citing Peshev et al. (below), that “Current research concentrates on multi-scale co-simulation by tool coupling.”. The work cited at Imperial College is one of many where a PME and one or several PMCs are coupled through CAPE-OPEN. Seems odd to single out this one, whatever its merits, when there is the APECS project, co-simulation between gPROMS and either PMEs or PMCs, and many more. Apparently the authors conclude that “with CAPE-OPEN it is not possible to couple simulations during runtime”. This statement is surprising.
