JSEQ sequences jobs in one-stage and two-stage processes, based on user-selected rules and evaluates the efficiency of the sequence.

Model Input Requirements

Format A, one-stage processes: For each job to be sequenced, provide the following on a separate line. Input order is only meaningful for the FIFO sequencing rule.

1. Job identifier - 1-8 character name, no embedded blanks
2. Job processing time:  days or hours required for completion of this job
3. Due date:  day or hour by which the job should be completed; after this time, the job is considered late or tardy

Format B, multi-stage processes: For each job to be sequenced, provide the following:

1. Job identifier - 1-8 character name, no embedded blanks
2. Stage 1 processing time:  days or hours required to complete the first stage or step
3. Stage 2 processing time:  days or hours for second stage
4. (etc., if additional stages are used)

Format C, two-stage with due dates:

1. Job identifier - 1-8 character name, no embedded blanks
2. Stage 1 processing time:  days or hours required to complete the first stage or step
3. Stage 2 processing time:  days or hours for second stage
4. Due date:  day or hour by which the job should be completed

Limits: program is limited to 50 jobs.
