Answer:
Yes. Certain kinds of firms do need to stress particular areas  of operations management. Operations management is a vast area which consists of several departments such as supply chain management, logistic management, warehouse management, data management, inventory management and etc. 
Companies, depending upon the kind of product and services they are supplying, need to figure out which department they are lacking in and should stress upon it.

Answer:
NPV= $31,808.91
Explanation:
Giving the following information:
Io= -$150,000. 
The operating costs:
Year 1= $5,000
Year 2= $6,000
Year 3= $7,000
The benefits:
Year 1= $80,000
Year 2= $90,000
Year 3= $70,000
To calculate the Net Present Value (NPV) we need to use the following formula:
NPV= -Io + ∑[Cf/(1+i)^n]
Cf= cash flow
Io= -150,000
Cf1= 80,000 - 5,000= 75,000/1.04= $72,115.39
Cf2= 90,000 - 6,000= 84,000/1.04^2=$77,662.72
Cf3= 70,000 - 7,000= 63,000/1.04^3= $56,006.77
NPV= $31,808.91

Assume that the price per ton of oranges in the international market is $810 and equilibrium is established at the price of $900 for 120 tons. 
Answer:
If Bangladesh is open to international trade in oranges without any restrictions, it will ____import____ tons of oranges. Suppose the Bangladeshi government wants to reduce imports to exactly 120 tons of oranges to help domestic producers. A tariff of ____$90____ per ton will achieve this.  A tariff set at this level would raise $___10,800______ in revenue for the Bangladeshi government.
Explanation:
A tariff of $90 per ton will raise the price of a ton of oranges to $900 ($810 per ton as indicated on the question).  When the price is raised to $900 in the domestic market, the quantity demanded will equalize with the quantity supplied at 120 tons.
