JSP Generator

Description

Benchmark generator for the Job Shop Problem (BG-JSP)

Parameters

Parameters available for the generation of problem instances:

1. Jobs:--jobs (-J)

   • Description: Number of jobs that will have the problem generated.
   • Possible values: List of integers. If you put more than one value in the list, all possible combinations will be made with the available machines.
   • Example of possible values: [3], [4, 5].
   • Default value: [10]

2. Machines:--machines (-M)

   • Description: Number of machines that will have the problem generated.
   • Possible values: List of integers. If you put more than one value in the list, all possible combinations will be made with the available jobs.
   • Example of possible values: [6], [2, 5].
   • Default value: [4]

3. Seed:--seed (-s)

   • Description: Base number for data generation.
   • Possible values: Integer value.
   • Example of possible values: 84, 32
   • Default value: 1

4. Speed Scaling:--speed-scaling (-S)

   • Description: Number of speeds that will be available to perform each task.
   • Possible values: Integer value.
   • Example of possible values: 3, 5
   • Default value: 1

5. Machine Processing Time:--machine-processing-time (-mpt)

   • Description: Base consumption for a machine in stand-by.
   • Possible values: List of floats that will have the same number of elements as available machines.
   • Example of possible values: [1.2], [1.2, 3.4]
   • Default value: []

6. Release and Due Date:--release-due (-RDDD)

   • Descripción: Establish that each task has an instant of release and an instant of completion limit.
   • Possible values:
     • 0: Neither the works and operations of each of them will have an instant of release or time limit for completion.
     • 1: The work will have instant of release and instant of completion limit.
     • 2: The operations of each job will have a release time and a limiting end time.
   • Example of possible values: 1, 2
   • Default value: 0

7. Path:--path (-P)

   • Description: Path where the problem instance file will be generated.
   • Possible values: String.
   • Example of possible values: ./problems, ./instances
   • Default value: ./output

8. Quantity:--quantity (-Q)

   • Description: Number of problem instances to be generated.
   • Possible values: Integer value.
   • Example of possible values: 2, 5
   • Default value: 1

9. Distribution:--distribution (-D)

   • Description: Type of distribution to be followed for data generation.
   • Possible values: You can only set one of the following values: uniform normal exponential
   • Example of possible values: uniform, exponential
   • Default value: normal

Example of JSON generated

This JSON shows how the data generated from an JSP problem with 2 machines and 2 jobs will look like. For this generation we have used the following parameters: -J [2] -M [2] -s 155632 -S 2 -mpt [50,60] -RDDD 1 -P ./problems -D exponential
