heuristics with bi directional T lanes

[Former Member]

If there is a bi directional T Lane between two DCs W1 and W2, and if location heuristics is run on W1 and W2 simulataneously for mututally exclusive products, what will be the behavior of heuristics?

Someone told me heuristics will go on for an infinite loop. Does it happen for mutually exclusive products also?

It depends, if you run heuristic selecting both the location, then heuristic creates PRs for W1 (sourcing from > W2) if there is supply available at W2 or creates PRs for W2 if supply available at W1.

You can try this in your system to know more, but yes dont worry you will not faceany infinite loop

Hi Manotosh,

Creating Bi-Directional T-lanes for the same product causes the low level code generation step failure due to cyclicity. This llow level codes are required for SNP heuristics to determine the run sequence and hence when the heuristics runs, it will create the Preqs and preq rel on both the locations once. It will not be going into infinite loop.

However the low level code job failure means that the low level codes for other new codes will also be not generated after the failure step. Hence issues can be seen in SNP heuristics run for other codes also. Hence it is imp not to create bi directional t-lanes for the same product.

However for mutually exclusive products i.e. two different products, there is no issue and you can create t-lane in one direction for one product and in reverse direction for the other product. It will not have any issues.

Let me know if it helps

try running unconstrained optimizer instead of heuristic.
