Question

Using constant workforce and varying inventory and stockout, what would be the constant workforce? Production required in periods 1,2 and 3 respectively are 1200, 1500 and 900 units. One worker during the panning horizoncan produce two units in one day. Number of work days are 22 in period 17 in period 2 and 21 in period 3. Assume that the beginning inventory and the edniong inventory required are 300 units each. What is the number of workers required during the planning horizon of three periods?

Answer 1

Total number of units to be produced in 3 periods

= 1200 + 1500 + 900

= 3600 units

It has been mentioned that starting and ending inventory both are 300 units each. Thus net numbers of units to be produced = 3600 units. Had beginning and ending inventory been different, the net requirement would have been different than 3600 units

Total number of working days in three periods

= 22 + 17 + 21

= 60 days

Number of units which can be produced by a worker per day = 2 units

Therefore, total units one worker can produce in three weeks

= 2 x60 units

= 120 units

Since we need a constant workforce,

Number of workers required in three periods

= 3600 / 120

= 30 persons

Hence, the number of workers required will be 30 persons
