A typical Master Production Schedule (MPS) should have:
- What you need to produce
- How much you need to produce
- When you need the items
However, the issue arises when in reality, the jobs in our factory cannot be plotted like the MPS below:
Since we are a job shop, the jobs to be made have unknown production rates due to different specifications (size, design, machine used, and etc.). Basically, each job is almost always unique in some way to other jobs.
So we do not know exactly how much to produce in a day as we just keep working on them until the jobs are finished. This means the MPS as shown above is not going to be practical in our application.
The only information provided to us that I can think of is shown below:
With these information, when to set these jobs and start producing them will depend on the deadline and how much is needed to be produced. So what is a good production schedule for these types of jobs (assuming there are 100 jobs and you cannot just eyeball them like the example shown here)
