Answer:
The demand location where demand is unmet is equal to Cleveland. Received only 75 units. 100 units demand is unmet.
Explanation:
Solution
From the example given, we solve for which demand location will have an unmet demand
Now,
The maximum quantity that can be shipped from Allentown to Erie is 100.
The Maximum quantity that can be shipped from Harrisburg to Cleveland is 175
While,
The Maximum quantity that can be shipped from Harrisburg to Dayton is 175
Hence, in case we want an solution optimum to get the required demand as many as possible with the supply given and with a low costs, then we need to find the optimum solution.
By applying a least cost method called greedy, we need to remove our least costing node and then provide minimum of demand and supply unit a present to each cell.
Thus,
The first least cost is Allentown to Dayton.
From Allentown to Dayton 100 units. Next least cost is Philadelphia to Erie.
From Philadelphia to Erie 150 units. Next least cost is Harrisburg to Erie.
From Harrisburg to Erie 25 units. Next least cost is Harrisburg to Dayton.
From Harrisburg to Dayton 75 units. Next least cost is Harrisburg to Cleveland
From Harrisburg to Cleveland 75 units.
So, for the optimum solution, the right choice of answer will be
From Allentown to Erie = 0 units
From Harrisburg to Cleveland = 75 units
From Harrisburg to Dayton = 75 units
Therefore, The demand location where demand is unmet is equal to Cleveland. Received only 75 units. 100 units demand is unmet.
