Q: Outline modelling steps for: 'How many checkout counters should a store open?' 1. Problem: minimize wait + staffing cost. 2. Assume: Poisson arrivals, exponential service (M/M/c!). 3. Formulate: W_q(c) vs cost(c). 4. Solve: queuing formulas, optimize c. 5. Validate: compare with real wait data! Iterate: refine assumptions! (Modelling: reality → math → reality!)
