Which of the following is NOT a disadvantage of a simulation? An optimal solution cannot be guaranteed, but relatively good ones are generally found. Simulation software sometimes requires special skills because of the complexity of the formal solution method. Simulation model construction can be a slow and costly process, although newer modeling systems are easier to use than ever. Simulation is often the only DSS modeling method that can readily handle relatively unstructured problems.

D. Simulation is often the only DSS modeling method that can readily handle relatively unstructured problems.

Explanation:

One of the advantages of simulation is that simulation is often the only DSS modeling method that can readily handle relatively unstructured problems.

Simulation is an imitation of reality which is carried out on a computer. It starts by first defining a problem that needs to be solved then a simulation model is constructed after that experiments are conducted and results are evaluated and then optimization is done where needed.

Decision Support Systems (DSS) is a simulation based information system that helps in decision making by incorporating various models to imitate real world scenarios. These models are capable of handling semi-structured or unstructured data that is in-fact one of the advantages of simulation.
