Use EOQ = sqrt(2DS/H) for the order quantity when demand is stable, and ROP = expected lead-time demand plus safety stock for timing. The Skill's inventory chapter walks through assumptions, units, and service-level selection with z values from the normal table.

Name the objective first: SPT minimizes average flow time, EDD favors due-date performance, and FCFS preserves fairness. No priority rule wins every measure, so the Skill's scheduling chapter compares each rule against your stated objective.

Cp measures potential capability assuming the process is centered between specifications, while Cpk accounts for off-center processes. Both require a stable process first, so run SPC control charts and remove special causes before computing either index.

Both suit data varying around an average. Exponential smoothing weights recent observations via alpha and needs less stored data; moving averages weight included periods equally. Larger alpha or smaller n increases responsiveness but adds noise.

No. It operationalizes audited chapter summaries, formulas, and decision rules, but defers to the chapter files when assumptions, table constants, or model conditions matter. Numerical recommendations still require current data, units, and local context.

Queue formulas require utilization rho = lambda/(servers x mu) below 1; at or above 1, waiting grows without bound. Check arrival and service rates, variability, and the number of servers before trusting L = lambda x W results.
