Operations engineering study guide (Industrial Engineering)
Operations engineering matches supply with demand. It starts with a forecast, because every later plan depends on it, and with capacity, because a forecast that cannot be produced is only a wish. Aggregate planning turns the forecast into a rough plan for workforce, inventory and subcontracting; material requirements planning explodes that plan into components and orders; scheduling assigns the work to machines and days. Inventory control decides how much to hold, and operational metrics decide whether the system is improving. Project management adds the network and the baseline, while the supply-chain half extends the same logic across suppliers, warehouses and customers. Every section opens with a quick-revision card, and the worked examples run from easy to exam level.
Structured by the official ETEC subject standard for this topic: every listed topic and learning outcome, with formulas, figures and worked examples. The full sections are available to members in the app.
