Capacity and constraint management Problem

 

Problem 1 Capacity Planning

A manager has the option of purchasing one, two, or three machines. Fixed costs and potential volumes are as follows:

Number of machinesTotal Annual Fixed CostsCorresponding Range of Output
1$ 9 6000 to 300
2$ 15 000301 to 600
3$ 20 000601 to 900

 

The variable cost if we operate only 1 machine is $10 per unit, but due to economies of scale it decreases to 9$ and 8$ if we operate together 2 and 3 machines, respectively. The price sold per item is $40.

Help the manager determine break-even point for each range. If projected annual demand is between 580 and 660 units, how many machines should the manager purchase?

 

Problem 2 Forecasting

Weekly demand at ABC Corporation is as follows:

Estimate demand for week 13 using a 4-week moving average as well as simple exponential smoothing with a = 0.1. Evaluate the MAD, MAPE and MSE in each case. Which of the two methods you prefer? Why?

For the exponential smoothing please use forecast 0f 104 in period 1

Problem 3 Forecasting

Monthly demand at A&D electronics for flat screen TVs are as follows:

WeekDemand(units)
19,000
212,000
321,000
433,000
512,000

720,000
835,000
914,000
1015,000
1130,000
1240,000

 

Estimate demand for the next two weeks (13 – what do you suggest as forecast in week 14) using simple exponential smoothing with a = 0.3 and exponential smoothing with trend adjustment (Holt’s Model) with a = 0.1 and b = 0.2.

For the simple exponential model use the level 20000. (see table below)

WeekDemand(units)Forecast

For Holt’s model, use level at period 1 to be L= 11000 and the trend in period 1 to be T1=1400. Evaluate the MAD, MAPE and MSE in each case. Which of the two methods you prefer and why?

(i) purchasing two new ovens that are each capable of baking a batch of 100 loaves in 3/4 hour, or

(ii) purchasing a new packaging line that is capable of packaging a batch of 200 loaves in 1/2 hour.

Which option would allow the greatest increase in the bakery’s overall capacity?

For (i) please answer 1,2,3,4 again

For (ii) please answer 1,2,3,4 again
