What is a typical disadvantage of developing simulation models?

• A. They provide too much precision.
• B. They can be completed almost instantly.
• C. The process can be time-consuming and expensive.
• D. They completely eliminate risk.

Answer: (C)

The main idea here is that building simulation models often requires substantial upfront investment in time and money. Crafting a faithful model involves gathering relevant data, setting up the model structure, validating it against real behavior, and designing and running experiments to explore outcomes. This whole process can be lengthy and costly because it depends on obtaining good data, using specialized software, and having the right expertise. Even after a model is built, running many scenarios or performing sensitivity analyses can add more time and resource use.

Other options aren’t as characteristic. Aiming for too much precision isn’t typical because simulations are inherently probabilistic and provide ranges or distributions, not exact forecasts. The idea that a model can be completed almost instantly is rarely true, since calibration and testing take time. And while simulation helps understand and manage risk, it does not eliminate risk entirely.
