Job sequencing is the arrangement of the task that is to be performed or processed in a machine in that particular order. Job sequencing problem has become the major problem in the computer field. A finite set of n jobs where each job consists of a chain of operations and a finite set of m machines where each machine can handle at most one operation at a time. Each operation needs to be processed during an uninterrupted period of a given length on a given machine and our Purpose is to find a schedule, that is, an allocation of the operations to time intervals to machines that has minimal length.

Abstract


Job sequencing is the arrangement of the task that is to be performed or processed in a machine in that particular order. Job sequencing problem has become the major problem in the computer field. A finite set of n jobs where each job consists of a chain of operations and a finite set of m machines where each machine can handle at most one operation at a time. Each operation needs to be processed during an uninterrupted period of a given length on a given machine and our Purpose is to find a schedule, that is, an allocation of the operations to time intervals to machines that has minimal length.
