Planning Based on Resource Priority and Product Priority


Hi Experts,

We have a scenario here that requires planning of products across multiple lines within the same plant. In a specific plant, I have 3 lines (Line-A, Line-B and Line-C). Products P-01, P-02, P-03, P-04 are produced in each of these lines in the following fashion



Line-A Line-B Line-C 1 P-01 P-02 P-01 2 P-02 P-04 P-04 3 P-03 P-03 P-03

The requirement is to have Line-A capacity utilized completely, before assigning demand to Line-B, and utilizing Line-B capacity before assigning demand to Line-C.

The caveat, however, is that all products are not produced on every line available, i.e., Product P-03 is produced in all lines (A, B, & C), Product P-01 is produced only in Line-A and Line-C, and Product P-04 is produced in Line-B and Line-C.

If there is a demand for P-01, P-02, and P-03, then

a. Line-A should be used to Produce P-01. If the capacity is completely utilized, only then product P-r01 should be produced in Line-C

b. Line-A should be used to Produce P-02, (after considering Product P-01 in Line-A) and if the capacity is insufficient, then product P-02 should be produced across Line-A and Line-B

c. If there is also a demand for Product P-04 on the same day as Product P-02 (as in case-b above), then Product P-02 should be produced 1st on Line-B and then Product P-04 should be scheduled on Line-B.

We intend to use the Optimizer to model this scenario however, how can one achieve resource prioritization (independent of product) in this case?

Please suggest the best / optimal way around this problem.
