Question 6 GNPC has three refineries that produce gasoline, which is then distributed to four large sterage facilisies. The total quantities (1000 barrebt) produced by each refinery and the total requirements (1000 barets) for each storage facilities, as well as the associated distribution costs are Shown as folfores. Due to recent challenges with storage facilities in Kumasi, the warehouse can only operate at 500 of its current storage capacity. a) Based on the information above, develop a netwoek graph of this problem showing all costs and decision variables. Determine the initial feasible solution using Northwest Comer flule and the total 11 cost under this method. b) determine the initial feasible solution using the Minimum Cell Cost and the total cost under this Method, Compare with the results in (a) and comment on the resulis based on the two approaches c) Due to the bad nature of the transportation channels, distributisn is prohibited trom Takoradi to Bawka. Forrmulate the mathemusical model to incorporate this in the problem Question 6 GNPC has three refineries that produce gasoline, which is then distributed to four large sterage facilisies.
