Q1. In perpetual inventory control, the material is checked as it reaches its ________value
(a) maximum
(b) average
(c) alarming
(d) minimum

(a) 10
(b) 20
(c) 30
(d) 40

Q3. The most suitable system for a retail shop is

(b) ABC Analysis
(c) VED Analysis
(d) GOLF Analysis

(a) Double exponential smoothing model
(b) Simple exponential smoothing model
(c) Brown’s quadratic smoothing model
(d) Moving average model (using 5 data points)

Q5. The value of the smoothing constant will be, when the current period forecast becomes equal to the last period forecast
(a) Infinity
(b) 2
(c) 0
(d) 0.5

Q6. A production line is said to be balanced, if at each station
(a) There is equal number of machines
(b) There is equal number of operators
(c) Waiting time for service is same
(d) Operation time is same

Solutions

S1. Ans. (d)
Sol. minimum value.

S2. Ans. (c)
EOQ=√((2DC_o)/C_h )=√(((2×9000×10))/2)=300 Units
So, No. of order=D/EOQ=9000/300=30

S3. Ans. (a)
Sol. FSN analysis
It is also known as fast moving slow moving and non-moving items.
It looks at quantity consumption rate and how often the item is issued and used.
It is generally used in retail shop.

S4. Ans. (d)
Sol. Moving average model (using 5 data points)

S5. Ans. (c)
Sol. When the value of smoothing constant equal to zero then the current period forecast becomes equal to last period forecast for
F_(t+1)=F_t+α(D_t-F_t)
When α=0, then F_(t+1)=F_t

S6. Ans. (d)
Sol. A production line is said to be balanced, if at each station operation time is the same.
