This job is best suited for someone with experience in Jobshop Scheduling, especially the Shifting Bottleneck heuristic procedure. Urgency is the most important aspect of this job. The code is required as soon as possible, a few hours being most suitable.
This is the most critical aspect/requirement.I am working on a project to write a code for a variation of the Shifting Bottleneck (SB) procedure for Jobshop Scheduling. Jobshop Scheduling involves trying to find a sequence for scheduling n jobs on m machines. The aim being to minimize the makespan of the network. Papers in literature explain the procedure well, such as Balas, Zawack, and Adams (1988) and Applegate and Cook (1991). The SB procedure and its algorithm is well documented in literature.
Jackson's algorithm, an extension of Johnson's method, involves scheduling of n jobs on two machines. Jackson's algorithm schedules four categories of jobs, those that require A, those that require B, those that require A then B, and those that require B then A.
I would like to implement this onto the SB procedure. Where instead of sequencing for a single machine in each iteration, I would like to pick two machines at each iteration. Then schedule these two machines using Jackson's algorithm. And continue with the conventional SB procedure.
These two links below provide codes for the general/conventional SB procedure.

I would like to have either (a) a new code that implements the SB procedure with Jackson's algorithm for each pair at each iteration, or (b) a modification of either of the above two codes to do the same.
In addition to the papers mentioned above, Section 5.4 of Michael Pinedo's book, "Planning and Scheduling in Manufacturing and Services" (2009) provides the traditional SB heuristic procedure which I need modified. Check under Algorithm 5.4.1 on page 90.
Python (preferred), Matlab or C would be acceptable for the work described above.
Any follow-up questions are welcome.

The payment/budget is greatly negotiable. Budget only for purpose of filling required field.
