Question 1
Johnson Food Pte Ltd produces canned corn for the local and overseas markets. They have
four raw corn suppliers as part of their strategy to reduce the risk of exposure to a single
supplier. Each day, Supplier 1, 2, 3 and 4 can provide 140kg, 100kg, 80kg and 60kg of raw
corn, respectively.
The purchased raw corn can be shipped to any of the three processing plants to be cooked and
canned. The processing capacity for Plant 1, Plant 2 and Plant 3 is 180kg, 140kg and 120kg
per day, respectively. Due to recent landslide, it resulted in the following logistical situations:
Supplier 3 can only ship to Plant 2 and Plant 3, while Supplier 4 can only ship to Plant 3.
Supplier 4s owner is a long-time family friend and there is an agreement that Johnson Food
Pte Ltd will purchase all that Supplier 4 could provide (i.e. it will purchase exactly 60kg of
raw corn from Supplier 4 every day).
The canned corn will eventually be sent to three warehouses for further distribution to the
local and overseas distributors. Warehouse 1 serves as the storage facility for the overseas
market while Warehouse 2 and 3 serves as the storage facility for the local market. Based on
projected demand, the amount of canned corn needed daily at Warehouse 1, 2 and 3 are at
least 160kg, 100kg and 120kg, respectively.
Table 1 shows the transportation cost ($/kg) from each corn supplier to the processing plants:

Processing Plant 1 Processing Plant 2 Processing Plant 3
Raw Corn Supplier 1 10 8 12
Raw Corn Supplier 2 8 9 10
Raw Corn Supplier 3 8 7 8
Raw Corn Supplier 4 8 9 14
Table 2 shows the transportation and storage cost ($/kg) from each processing plants to the
warehouses:

Processing Plant 1 20 18 16
Processing Plant 2 18 20 18
