Based on right and left justification of activities, the iterative forward/backward scheduling technique presented in  iteratively applies serial forward and backward scheduling for several times.
In the same fashion stated in , a gene determines whether the serial or parallel schedule generation scheme should be used, and another gene determines whether the forward or backward scheduling should be used.
An Integer Linear Programming model is developed for the first decision, backward scheduling logic for the second decision in solution methodology 1 and forward scheduling logic for the second decision in solution methodology 2.

From the ATS, dough delivery is forward scheduled to ensure a constant supply, while backward scheduling
from the ATS is needed to ensure that the mixing machines begin production in time to meet the production schedule.
The details of the foresight check is very similar to the key backward scheduling primitive that we have developed; backward-scheduling requires a repetition of a sequences of steps that is similar to the foresight check.
For instance, the classical critical path heuristic can be seen as backward scheduling while ignoring all resource constraints.
Solomon IV Manufacturing Work Order includes easy-to-use graphical work order creation and inquiry, multiple production targets with redirection capabilities, work order advice/generation, purchase order advice/generation, forward and backward scheduling
and unparalleled allocation flexibility.
"We normally use backward scheduling
on all jobs where lead time appears to be sufficient," Todd notes.
The concept has existed in a simple form in scheduling literature under the name "backward scheduling
." In the library of AI techniques, a somewhat similar concept of backward chaining is used.
Krepchin Coming to terms with scheduling Here are a few of the terms used by scheduling professionals to describe what they do: Backward scheduling
. Starts with the date the order is required and calculates backward to determine the proper release date.
The scheduling module provides forward and backward scheduling
and production capacity planning for all production machines and secondary operations.
