Dependent demand is the requirement for stock item which is directly related to and therefore de-pendent upon the rate of production (examples are: raw materials, components, energy).
Independent demand is the requirement for stock item which is not directly related to, and is therefore independent of rate of production.
'Number of independent demand items may be derived from the forecast': Although independent demand is called thus, it can still be influenced by economic factors external to the demand-supply model such as general consumer sentiment and consumers' available disposal income. However, businesses that need to predict the number of products with independent demand needed to sate their customers have it easier than businesses that must calculate the demand for products with dependent demand because there are fewer factors to consider.
'Dependent demand items are not directly correlated with production rate': As mentioned above, dependent demand items are directly correlated with production rate.
'All indirect supplies are independent demand items': Though most indirect supplier are inde-pendent demand, some are determined by the production rate, i.e. energy consumption of a major machinery.
'Car engine is an example of independent demand items in a car assembly plant': Car engine is a component in car which is the finished good of a car assembly plant, it is a dependent demand item.

Weighted moving average
Explanation:
The most common subjective forecasting techniques include the following:
- Market surveys
- Employee surveys
- Expert knowledge (Delphi method is a method using expert knowledge)
- Test marketing
Cycle counting is a periodic analysis of inventory in a storage location which is conducted through the counting of samples instead of physically counting the entire inventory available, so as to quickly have an accurate estimate of the inventory available without causing a stop to the day to day working as is the case with physically counting every unit.
The Pareto principle (also known as the 80/20 rule, the law of the vital few, or the principle of fac-tor sparsity) states that, for many events, roughly 80% of the effects come from 20% of the causes.
Weighted moving averages assign a heavier weighting to more current data points since they are more relevant than data points in the distant past. The sum of the weighting should add up to 1 (or 100 percent).

Material requirement planning (MRP) is a production planning and material (inventory) control system used in manufacturing. Objectives of MRP are to ensure materials are available for production while minimising inventory and to plan production and procurement activities.
MRP software combines the master production schedule, the bill of materials and the inventory information to work out the net requirements (net MRP) of what to purchase or produce and when.
These net requirements are worked out using the following equation:
Net requirements = Total requirements - Available inventory
Where:
Total requirement = Gross requirements (gross MRP)
Available inventory = Inventory on hand + Units on order
In the other words, Gross MRP = Net MRP + Available inventory, so the answer should be "The gross MRP includes consideration of available inventory, whereas the net MRP does not" LO 2, AC 2.3

The purposes of stores and warehouses are:
1. Maximum use of space.
2. Ready access to all items.
3. Efficient movement of goods.
4. Effective utilization of labour & equipment's
5. Maximum protection of items
6. Good-house-keeping.

Economic order quantity (EOQ) was developed in 1913 by Ford W.
Harris and has been refined over time. The formula assumes that demand, ordering, and holding costs all remain constant. The EOQ minimizes the total annual inventory cost.
EOQ formula is as follow:
