It is a variant of optimal job scheduling. In a general job-scheduling problem, we are given n jobs J1, J2, ..., Jn of varying processing times, which need to be scheduled on m … Ver mais The input to the open-shop scheduling problem consists of a set of n jobs, another set of m workstations, and a two-dimensional table of the amount of time each job should spend at each workstation (possibly zero). … Ver mais • Job-shop scheduling is a similar problem but with a yet additional constraint – the operations must be done in a specific order. • Flow-shop scheduling is a job-shop scheduling but with an additional flow constraint – each operation must be done on a specific machine. Ver mais The open-shop scheduling problem can be solved in polynomial time for instances that have only two workstations or only two jobs. It may also be solved in polynomial time when all nonzero processing times are equal: in this case the problem becomes equivalent to Ver mais on the other hand など https://robertgwatkins.com
