Which system is a computer-based system that can create detailed production schedules using real-time data?

• A. MRP II
• B. ERP
• C. MPS
• D. APP

Answer: (A)

When a question points to a computer-based system that can create detailed production schedules using real-time data, the emphasis is on systems that actively plan and adjust the shop floor based on current conditions. MRP II is designed to do this by extending materials planning to include capacity planning and detailed scheduling. It links the master production schedule with available resources, shop-floor data, lead times, and constraints, continuously updating schedules as real-time information comes in. This creates executable, detailed production schedules that reflect what can actually be produced given current capacity, inventory, and equipment status.

The master production schedule itself is a plan of what to produce and when, but it doesn’t by itself manage capacity or convert that plan into real-time, detailed shop-floor schedules. An ERP system covers a broader scope across the enterprise and often includes MRP II-like scheduling, but the question focuses on the capability to generate detailed, real-time schedules specifically for manufacturing. The remaining option, typically representing advanced planning and scheduling, is a different category that focuses on optimization of production sequences and deadlines, which isn’t the emphasis of the described system here.
