In the crisis scenario, from the given below table, it can be observed that demand is 40000 units, the order cost is £190 and Holding cost £1.45 then the company should order 12.35 per year in order to reach the optimal equilibrium point where the demand equal to the supply. This will save the extra cost of the company on holding the inventory; if they demand 40,000 units in the year their total cost will gather to £ 4694.68.

In the slow recovery scenario, from the given below table, it can be observed that the demand is 65,000 units, the order cost is £190 and Holding cost (H) £1.45 then the company should order 15.75per year in order to reach the optimal equilibrium point where the demand equal to supply. This will save the extra cost of the company on holding the inventory; if they demand 65,000 units in the year their total cost will accrue to £ 5984.56.
