Troubleshoot ‘Entities Exceeding Limit’ In ArenaOctober 9, 2007
The fun of using Arena simulation software may turn into disaster when the modeling is getting more complex. This especially happens when the Academic version being used, can no longer accommodate modules from the blocks panels to be utilized in the model, due to module amount limitation.
When a dialog box appearing unexpectedly telling us that we have exceeded its limit.
That’s so IRRITATING.
You Have Exceeded Arena Limit
Or maybe the amounts of module blocks are fine. No warning. No dialog box popping up.
But during simulation run, an error message comes up saying that maximum entities limit is exceeded.
Another annoying disturbance!
Run Error Caused By Exceeding Entities Created
Take it easy!
Now, there is a solution for that.
Another technical tips provided by Mr. Arya Wirabhuana, senior modeler from UTM
Follow these steps:
- Build the model with low version of Arena (version 5 or lower), with neither statistics nor graphics module used.
Create the graphics manually from its auto generated report, using Ms. Excel, then copy-paste it to the Arena working area.
- Always focus on model building objective: for presentation OR for analysis.
For presentation purpose (where eye-catching face validity is a must), break the model into several files, so that more animations can be made within each file. Making the clients impressed is very important here.
For analysis purpose, delete any unimportant animation. Prevent too much simplification that will cause the model to be invalid
Also, do not ruin the integrity of the model by breaking it into some files
- Modify the input data to eliminate any possible queue.
- Use more module blocks from Advanced Panel instead of Basic Panel.
Avoid using too many modules is the key.
- Make short replication.
In the case you want long replication, keep it short, but run several times without initializing the system. Initialization is set only for the statistics.
- If the model is done, try to save it, and then reopen the file in the higher version of Arena.
e.g. Open with Arena 8.0. There the file needs to be converted to the corresponding Arena version.
- After the conversion, you can see that Arena can still accommodate some additional modules.
This is probably because module blocks from Arena lower version is considered much simpler that more blocks can be added later.
With this technique, the possibility of facing entity exceeds the limit is minimized.
Thus, the fun of modeling with Arena can still go on!
This is NOT cheating…
Successful try on modeling automated truck assembly section body shop & metal finish using Arena 8.0. has proven that this technique is working. It’s worth to try!
