USING THE MATHEMATICAL FORMULATION METHOD

the SUPPLY EQUATIONS (Si) can be expressed as
#101 + #102 + #103 + #104 = S1 = 150 (1)
#201 + #202 + #203 + #204 = S2 = 40 (2)
#301 + #302 + #303 + #304 = S3 = 80 (3)
the DEMAND EQUATIONS (Dj) can be expressed as
#101 + #201 + #301 = D1 = 90 (4)
#102 + #202 + #302 = D2 = 70 (5)
#103 + #203 + #303 = D3 = 50 (6)
#104 + #204 + #304 = D4 = 60 (7)

the OBJECTIVE will be to minimize the overall shipping
COST which is the shipping cost per unit multiplied by
the corresponding volumes: Cij * (#i0j).
MINIMUM = 27.0* #101 + 23.0* #102 + 31.0* #103....
...........+ 35.0* #303 + 57.0* #304
or.
MAXIMUM = -27.0* #101 - 23.0* #102 - 31.0* #103....
............- 35.0* #303 - 57.0* #304
The second form of the OBJECTIVE FUNCTION will allow us
to use the default automatically created by BEST-PLAN
labeled " max: profit". Shipping COSTS can then be
entered using the COST data statements.
