Which of the following is NOT a type of model used in operations management?

In operations management, various types of models are employed to aid in decision-making, problem-solving, and optimizing processes. Physical models represent tangible objects, such as a scale model of a factory. Schematic models provide a visual representation of a system, often highlighting relationships and processes, like flowcharts or diagrams. Mathematical models are used to formulate relationships through mathematical expressions, allowing for analysis and predictions based on defined variables.

Qualitative models, while valuable in many fields, do not fit within the conventional framework of models used specifically in operations management. Operations management heavily relies on quantitative data and models that provide measurable outcomes, making the emphasis on qualitative assessments less relevant in this context. Thus, the identification of qualitative models as not being a type commonly associated with operations management reflects the focus on data-driven methodologies in this discipline.
