This is a software simulation of a job shop. It is designed for the following uses:

1. Help students and researchers understand the dynamics of a working job shop by allowing interactive user-controlled scheduling.
2. Help design and test new heuristics/algorithms for scheduling job shops.
3. Allow for easy distribution (marketing) of heuristics/algorithms by means of Java applets.
4. Integrate into a simulation that will repeatidly call the "simulation kernel" of this software package and gather statistics regarding the performance and usefullness of several scheduling heuristics.

1. Stand alone application.
2. Java2 applet.
3. Simulation kernel classes.

It allows the user to schedule the job shop interactivly, or watch a pre-programmed algorithm perform the scheduling step by step.

Using the stand alone application is more recommened than using the applet (download from below).

The simulation kernel classes are to be incorporated into a simulation study. The classes are programmed in an OO manner such that additional algorithms and shop data formats can be pluged in.

Currently the application uses example files as specified in the link below. The software is written in Java2. The gantt chart is part of the simJava system by Fred Howell and Ross McNab. The Java2 run time enviornment is needed inorder to run both the application and the applet.

• Run Applet (May not work properly on some machines)
• Example job shop files (jbs files).
• Download source files.
• Download source files docs (javadoc generated).
• Old distributions (of previous versions).

To try it out you should:

1. Download (Use the link above).
2. Unzip the contents of the downloaded file into any directory.
3. Makesure you have the Java Runtime Environment 1.3 installed: Go to javasoft's site
4. On a Windows machine, double click the shopsim.jar icon in the directory containing the contents of the zip file. On a Linux or Solaris machine, type:
   java -jar shopsim.jar
   The JobShopSimulation should startup. You can then try out some example files that are supplied in the zip by openning them, selecting an algorithm, and running the simulation.
