The seymore manufacturing company has developed the following
demand forecast for the next year.
Quarter 1 Quarter 2 Quarter 3 Quarter 4
Demand - 5,000 10,000 8,000 2,000 respectively
At the beginning of January 1, there are 1000 units of on-hand
inventory. Other data available with the firm are: Hiring cost
per employee = Rs. 200; Firing cost per employee = Rs. 400;
Beginning workforce = 60 employees; Inventory carrying cost = Rs. 2
per unit per quarter of end inventory; Stockout cost (S)= Rs. 5 per
unit; Regular payroll = Rs. 1200/- per employee per quarter;
Overtime cost = Rs. 2 per unit; and each employee can produce
100 units per quarter.

for hiring, firing, workforce, inventory carried, overtime
production, regular time production and stockouts,
respectively).
 What would be the quarterly production and cost, if
