5.
MAD = Sum of absolute values of differences between slaes and forecast / No. of periods
= I(8-5)I+I(10-6)I+I(15-11)I+I(9-12)I /4 = 14/4 = 3.5
B is correct.
6. I, II and III are operations management decisions. Marketing and pricing are not strategic operations management decisions. C is correct
7. Forecast for the next period
= forecast for the previous period + alpha ( sales for pervious period - forecast of pervious period)
= 99+0.4x( 103-99) = 100.6
E is correct.
8. Fraction Increase in productivity = 2000/ 1600 = 5/4 =1.25
Which means that there is 25% increase in productivity
C is correct.
9. Forecast = 5x3000+3x2200+1x1000 /9
= 15000+6600+1000/9
= 22600/9 = 2511.11
D is correct
10.
There are four paths in the network viz. ACE, BCE,BDE and ADE.
C is correct.
11. Here, Ta =2, Tm =3 and Tb =8
Expected duration = Ta+4Tm+tb / 6 = 22/6 =3.66
Variance = [Tb-Ta /6]2 = (6/6)2 =1
A is correct.
