What is scheduling?
Scheduling is a method where there is a set of x tasks which need to be completed on a set of y resources in an efficient manner. Wikipedia gives us a good definition of scheduling “Companies use backward and forward scheduling to allocate plant and machinery resources, plan human resources, plan production processes and purchase materials.”
What is forward scheduling?
Forward scheduling is taking a job with a number of tasks and allocates those tasks to resources as early as possible when resources the resources allow. The first available time that the resource is available to be used the task should make use of it. As with all scheduling methods there are pros and cons on how they work. Forward scheduling may result in jobs being completed earlier then the requested due date because forward scheduling schedules the tasks as early as possible. Forward scheduling tells you when a job could be completed vs completing the job when required.
What is backwards scheduling?
Backwards scheduling is taking a job with a number of tasks and allocates those tasks to resources in reverse orders and schedules the task on the resource. Backwards scheduling requires a delivery date from the customer because the system schedules backwards from the delivery date to arrive at a start date. Backward scheduling tells the manufacturer if this date could be hit based on the allocation of resources. Unlike forward scheduling which schedules into the future, backward scheduling could potentially schedule into the past because the resources were not available to complete the job. Backwards scheduling then may turn around and actually forward schedule the job to tell the customer the earliest delivery time.
Scheduling is very complex and this blog will try to go over many aspects of scheduling from types of scheduling, nap complete problems, how to allocate resources, defining resources, etc.
