What commissioning method utilizes simulations to predict system performance?

The commissioning method that utilizes simulations to predict system performance is pre-functional testing simulations. This approach involves creating simulations to model how a system will perform under various conditions before it is fully operational. By using these simulations, technicians can identify potential issues, optimize system designs, and ensure that systems will function as intended when they are put into use. This predictive capability allows for adjustments to be made early in the process, which helps in achieving better overall system efficiency and reliability.

In contrast, the other methods listed do not primarily focus on using simulations for performance prediction. System performance audits assess the operational efficiency of existing systems, operational capacity testing evaluates the functionality of systems in real-time, and standards verification assessments check compliance with specific protocols or benchmarks. While all these methods are important in the commissioning process, they do not specifically employ simulations to forecast how systems will behave in practice.
