Conveyor Capacity by part type

Hello All,

I am new to flexsim forum but i had been working on flexsim and other simulation software's from last 1.5 years
Here is my problem to define conveyor capacity in new conveyor module.

In the new conveyor module there is no concept of conveyor capacity which will be automatically defined by accumulation length(Spacing between objects) which we define.

But I would like to define conveyor capacity as per my client requirement.

Lets me explain the situation with example.

Let us consider 3 part types.
1) Part_A weight =4 kg
2) Part_B weight =2 kg
3) Part_C weight =1 kg

let us say any time my conveyor can bare only 10 kg of weight.So,I want to restrict the capacity of conveyor based on part types present on conveyor.

Could any one suggest a simple way to do this problem.


Thanks in advance,

I recommend you can use label and custom script in triggers of trigger tab.

1) classify the flow items to three itemtypes of A, B and C (!, 2 and 3).
2) Sum the weight of flowitems to label when flowitem enter in conveyor and exit.
3) Close and open the input port based on the limit of capacity.


But...
I hope someone will solve your task by using the more easy way than above.

Thanks Syseo for the reply

But in the new conveyor module in flexsim 7.5.4 we have only two triggers 1)on reset and 2)on message in which we cant check or track the part entry and exit.
I think we need to use decision points on conveyor to track but it is very difficult to use two decision points in the entry and exit of each conveyor and having a center connection between these two decision points to track the parts between these two points.

I am looking forward for an easy solution that can be implemented for entire conveyor system(for hundreds of conveyors).

Thanks in Advance.

If you use photo eyes or decision points and create a usercommand for the onblock trigger and if you use a globaltable or a global array to store the current weight per part you don't have to make any connections.
You can even put the PE of DP with the usercommand call in a user library and generate those automatically (you ofcourse have to generate 2 so a begin and an end PE or DP)

You can also put a number in a label on the PE's or DP and use that as an entry into the global table..

If you creating a system with hunderts of conveyors and you are creating it automatically you can also create your PE's or DP automatically and the numbering should be no problem. Actually in that case using a centerport connection is no problem either because these can be made with code also.

If you create the large conveyor system by hand it is no problem to put a number on the PE's or DP's to distinguish them. If you do that and use a global table you can use the global table also to make distinction between different parts that can carry different weights.
