Assign more weight to the recent demand data

Include new demand data in the average without discarding the earlier data

Include new demand data in the average after discarding some of the earlier demand data

5. A regression model is used to express a variable Y as a function of another variable X, this implies that

There is a causal relationship between Y and X

A value of X may be used to estimate a value of Y

Values of X exactly determine values of Y

Simple average method

Moving average method

Weighted moving average method

Exponential smoothing method

8. In simplex exponential smoothing forecasting, to give higher weightage to recent demand information, the smoothing constant must be

-1

Zero

0.5

9. In an ideal inventory control system, the economic lot size for a part is 1000. If the annual demand for the part is doubled, the new economic lot size required will be

500

2000

1000/√2

1000√2

10. When the annual demand of a product is 24000 units, the EOQ is 2000 units. If the annual demand is 48000 units the most appropriate EOQ will be

1000 units

2000 units

2800 units

4000 units

11. If the demand for an item is doubled and the ordering cost halved, the economic order quantity

Increase by factor √2

Is doubled

Is halved

12. Setup costs do not include

Labour cost of setting up machine

Ordering cost or raw material

Maintenance cost of the machines

Cost of processing the work piece

13. In inventory planning, extra inventory is unnecessarily carried to the end of the planning period when using one of the following lot size decision polices:

Lot for lot production

Economic order quantity(EOQ) lot size

Period order quantity(POQ) lot size

Part period total cost balancing

14. A company uses 2555 units for an item annually. Delivery lead time is 8 days. The reorder point(in number of units) to achieve optimum inventory is

43.3%

14.8%

14.0%

16.3%

16. If at the optimum in a linear programming problem, a dual variable corresponding to a particular primal constraint is zero, then it means that

Right hand side of the primal constraint can altered without affecting the optimum solution

Changing the right hand side of the primal constraint will disturb the optimum solution

The objective function is unbounded

The problem is degenerate

17. Simplex method of solving linear programming problem uses
