13. Tell me what is inventory control?
Inventory control is the process of reducing inventory costs while remaining responsive to customer demands. By this definition a store would want to lower its acquisition, carrying ordering and stock-out costs to their lowest possible levels. However a store would need to have enough inventories to meet any needs of its customers.
14. What does periodic review mean?
☛ Ordering inventory at a predetermined re-order level
☛ Ordering inventory when it falls below the designated safety stock level
☛ Ordering inventory in consultation with suppliers relative to their available capacity
☛ Ordering inventory to supplier call-offs on an as required basis
☛ Ordering inventory at a fixed and regular time interval
15. How would you determine the value of inventory?
The value can be found using four methods in inventory control. The first is the specific cost in which each item's cost is added together for the inventory's value. A second method is to use the weighted average of the costs for a period to determine value. A third method is first in, first out. In this method value is measured using the latest costs of goods while working towards the beginning of the period until all goods in inventory are valued. The final method is last in, first out. In this method the costs of gods at the beginning of the period are used to determine the inventory's value.
16. Tell me about the important considerations in inventory control?
For inventory control to work at its best a store must consider the costs of acquisition, carrying, ordering and stock-out. the store must also look at its reordering system, its budgeting for inventory, insurance and forecast the demand.
17. How does an inventory effect in a store?
Inventory levels and their values can effect the income of the store, the amount of taxes paid and the total stocking cost.
18. Do you know the importance of EOQ level?
The EOQ level is the point at which stocking costs are at their lowest point for a given item.
19. When does the model work in inventory?
The model only works for those cases that meet its assumptions.
20. Do you know what is the formula of EOQ?
The EOQ formula is the square root of 2 times demand times order completion cost divided by carrying cost. The mathematical formula is square root of 2DS/C.
21. Will it effect the EOQ model, If you get a discount?
Yes, a discount will cause the basic EOQ model to fail. To use a discount in determine a EOQ you must use the EOQ model with quantity discounts.
22. What would happen if there is no savings or the models produce even results?
If there is no savings a error in the calculations may have occurred or the model does not fit your case. For instances were the total stocking costs are even you may use either order quantity.
23. Tell me when should you take a physical inventory?
A inventory should be taken at least once a year. If items are perishable, seasonal or highly demanded a inventory should be taken more often.
24. Can you tell me what types of forecasting can you do?
There are two types of forecasting qualitative and quantitative. Qualitative uses personal opinions to determine forecasts. Quantitative uses numerical data and statistical modeling to determine forecasts.
25. How would forecasting help in controlling inventory?
Through the use of forecasts inventory levels can be set to meet the demands while keeping levels as low as possible.
