The best models a. are mathematical models. b. replicate all aspects of the real-world object or decision. c. replicate the characteristics of a component in isolation from the rest of the system.

accurately reflect relevant characteristics of the real-world object or decision

Step-by-step explanation:

a. are mathematical models. b. replicate all aspects of the real-world object or decision. c. replicate the characteristics of a component in isolation from the rest of the system.

accurately reflect relevant characteristics of the real-world object or decision

A model is an abstraction of reality. not all good models are mathematical. there are good models in economics that are accurate and do not use maths. e.g. law of demand

It is impossible for a model to replicate all aspects of the real-world object or decision. It will only be able to reflect relevant characteristics of the real-world object or decision. All other factors would be held constant
