A commodity is to be supplied at the constant rate of 200 units per day. Supplies of any amountcan be had at any required time but each ordering costs Rs. 50/-. Cost of holding the commodity ininventory is Rs. 2/- per unit per day while the delay in the supply of the item induces a penalty of Rs.10/- perunit per delay of one day. Find the optimal policy, q and 1, where t is the reorder cycle period and q isthe inventory level after reorder. What would be the best policy if the penalty cost becomes infinity?

The fixed cost of production is P120,000 a month. (a) What is the break-even point? (b) What is the"unhealthy point"? (c) What is the profit or loss if production is 60% Of capacity? Ans.(a) 100 units/month, (b) 128 units/month, (c) P62,667 per month
The capital cost of a hydro-power station of 50 MW capacity is Rs 1,000 per kW. The annual depreciation charges are 10% of the capital cost. A royalty of Re 1 per kW per year and Re 0·01 per kWh generated is to be paid for using the river water for generation of power. The maximum demand on the power station is 40 MW and annual load factor is 60%. Annual cost of salaries, maintenance charges etc. is Rs 7, 00,000. If 20% of this expense is also chargeable as fixed charges, calculate the generation cost in two part form.
