What are the classification of operation research model?

Operations research models are typically classified based on their structure and nature, with common classifications including deterministic vs stochastic models, static vs dynamic models, and discrete vs continuous models. Deterministic models assume perfect information and known inputs, while stochastic models factor in uncertainty and randomness. Static models are based on a single period of time, while dynamic models consider multiple time periods. Discrete models involve integer or binary decision variables, whereas continuous models use real-valued variables.
