Consider an order allocation

6.11     Consider an order allocation problem under multiple sourcing, where it is required to buy 2000 units of a certain product from three different suppliers. The fixed set-up cost (independent of the order quantity), variable cost (unit price), and the maximum capacity of each supplier are given in the following (two suppliers offer quan- tity discounts):

 

Supplier    Fixed Cost     Capacity                         Unit Price

1

$100

600 units

$ 10/unit for the first 300 units

 

 

 

$7/unit for the remaining 300 units

2

$500

800 units

$2/unit for all 800 units

3

$300

1200 units

$6/unit for the first 500 units

 

 

 

$4/unit for the remaining 700 units

 

 

 

 

Criteria

 

Flexibility                               Price      Service

 

Sub criteria

 

Process capability Defective parts       Distance Lead time

 

FIGURE 6.8

Supplier selection criteria and sub-criteria (Exercise  6.12).

 

The objective is to minimize the total cost of purchasing (fixed plus  variable cost). Formulate this as a linear integer-programming problem. You must define all your variables clearly, write out the constraints to be satisfied with a brief explanation of each and develop the objective function.
