- To classify items in inventory based on their value, availability and consumption rate
- To manage independent demand of an item
- To determine the capacity requirement to produce a product
What is ERP?
What is ERP?
- A type of MRP computer system
- An advanced MRP-II system integrated with customers and suppliers (correct)
- A system used to manage inventory based on their value, availability and consumption rate
- A system that is not related to MRP or MRP-II
What is the formula to calculate the order quantity?
What is the formula to calculate the order quantity?
- Q = d (t b + L) + Z σ d t b + L - I (correct)
- Q = d (t + L) + Z σ d t b
- Q = d (t b - L) + Z σ d t b + L
- Q = d (t - L) + Z σ d t b

Study Notes
Forecasting
- In trend-adjusted exponential smoothing, the forecast consists of an exponentially smoothed forecast and a smoothed trend factor.
- The mean absolute deviation (MAD) is used to measure forecast accuracy.
- Moving average forecasting techniques are used to smoothen the variations in the data.
- Associative forecasting is primarily done using regression analysis.
- Customer service levels can be improved by ensuring the order quantity is sufficient, e.g., for 95% service level, the order quantity should be Q = d (t b + L ) + Z σ d t b + L − I.
Inventory Management
- Material requirement planning (MRP) specifies the quantity of materials required to produce products, quantities and timings of planned orders, and capacity requirements.
- Enterprise resource planning (ERP) is an advanced MRP-II system integrated with customers and suppliers.
- Dependent and independent demand of an item differ in terms of their demand patterns.
Flexible Manufacturing Systems
- Flexible manufacturing systems (FMS) consist of highly automated group technology machine cells, integrated computer systems, and forecasting.
- Retrieval CAPP (Computer-Aided Process Planning) is based on the determination of routesheet by an engineer, whereas generative CAPP is based on part family and automated search of route sheet.
- A DNC (Direct Numerical Control) system can control more than one machine simultaneously and generate programs automatically.
Material Handling
- Material handling covers the processes of storing, handling, and moving materials.
- Selection of material handling equipment is based on factors such as size, shape, weight, and volume of materials, layout of the plant, and production processes.
- Material handling efficiency and automation can be improved by considering factors such as material handling cost, cost of equipment, and production processes.
Production Planning and Control
- Production planning and control (PPC) is a tool to coordinate all manufacturing activities.
- Expediting ensures that production is carried out as per plan and delivery schedules are met.
- PPC involves sequencing of operations, routing, time scheduling, and other activities to ensure efficient production.
