Ladies and Gentlemen,

I am trying to move a large volume of data (about 4kb worth) from the function in C++ that generates this data in the dll to the flexsim object that calls this function. The function is called quite frequently and it always produces a new set of data, so prepocessing it and loading it out of the database/excel is impossible.

I got it working using sendmessage in a loop, but I would like to know if there is a better way of doing it because sendmessage'ing so much data in one call seems to put a lot of strain on the simulation.

Is it possible to create some kind of container data structure in memory and pass the pointer to it from the dll to flexsim or something along those lines?


Also, I noticed that in C++ I can pass a lot more parameters to sendmessage than in FlexScript. Is there any way to work around the restriction of at most 3 arguments?


Thank you!

another problem with generating reports. Because I write several information in different excel files, respectively close one file and open another one. I sometimes get the following error:



My Flexscript code is fine, I don't run into problems if I'm in debugging mode and go through the code step-by-step.

Is there a possibility to make Flexsim wait for x seconds until the next line of code is processed?
A dirty walk-around would be to include complicated calculations in a loop or writing a dummy globaltable, but I want something fancy :)

Does somebody have an idea?

Thanks in advance!

simple question. Which nodefunction is executed when I use the report() command?

I want to include some other data in the .csv file (like repetition and scenario number). I found the project/exec/globals/nodefunctions/summaryreport code, but I assume this is not the right one, because I foundthe following code
Code:
fpt("Flexsim Summary Report"); fpr();
But it's only "summary report" in the exported .csv file.

What do I have to edit to customize the report() function?

Thank you all in advance!

Ladies and Gentlemen,
I am trying to arrange my flexsim project as follows:

|
| - Racking/

| - Roadmap/

for the purpose of source controlling it.

My problem is that I cannot figure out an elegant way of specifying that a list of paths {P11,..,P1n} goes into file F1, {P21,..,P2m} goes into file F2, and so forth, without assuming that the paths are always arranged sequentially in the root of the model.

It seems that I can accomplish it by creating split points, but the way I understand the process, split points only work if the tree is arranged a certain way, so if I add another forklift at a later date, it will go to the end of the tree and will be saved in the wrong file unless I somehow reorder the tree.
I tried creating multiple entries with different paths but the same file but that only saves the last entry.
I tried listing several paths in the same entry separated by a commas, semicolon, or space, but that didn't work at all.

Thank you!

I have 120 fixed resources “A” (queues) connected to 120 fixed resources “B”. Each new production run is potentially configured differently, i.e. any “A” can be connected to any “B”. I could hard wire the connections and manage the ports for flowitems using labels on the flowitems. But this gives me a very messy set of connections approx (14,400 connections).
Instead I dynamically draw the appropriate connection. I can draw the connection ok but NO ITEMS WILL FLOW DOWN IT. If I reset the model and leave the connection in place then the flowitems will flow down the connection on the second run. Why? I have searched through the manual for clues as to why this may be happening but can’t find any help.
I create the connection between “A” and “B” when the 1st flowitem enters the fixed resource “A”. I only create 1 connection (i.e. when nrop ==0) and would normally remove it on reset. ]]> DavidPlatt http://www.flexsim.com/community/forum/showthread.php?t=2158 Avoiding collisions with dynamically placed fixed resources http://www.flexsim.com/community/forum/showthread.php?t=2157&goto=newpost Sun, 13 May 2012 22:28:49 GMT I am new to Flexsim and am looking for a good example of a model where an operator (task executor) uses collision to avoid dynamically placed fixed... I am new to Flexsim and am looking for a good example of a model where an operator (task executor) uses collision to avoid dynamically placed fixed resources (a queue).
Problem Description:
I have a Pick to Light production line of 120 pick stations, each pick station is fed by a 1m feeder (in this case a queue). We have 10 extensions (also 1m long queues) which get added to the busiest feeders at the start of each production run.
All of the feeders are replenished by operators who pick replenishment stock off pallets and place it on the feeders. There are 2 replenishment operators who manage the whole line.
I could use network nodes and paths to direct the operators but would have to draw the network each new production run as the position of the extension feeders changes. What I was hoping to use is the collision handling capability to enable the replenishment operators to move around the extension feeders rather than walk through them. I have tried to use the collision but could get it to function and was unable to find out why from the manual. ]]> DavidPlatt http://www.flexsim.com/community/forum/showthread.php?t=2157 Ignore unavailable outputport http://www.flexsim.com/community/forum/showthread.php?t=2156&goto=newpost Fri, 11 May 2012 07:06:19 GMT Hello everybody, I want to ignore if an output-queue is unavailable (because its maximum content is reached), move a FlowItem anyways and print a... Hello everybody,

I want to ignore if an output-queue is unavailable (because its maximum content is reached), move a FlowItem anyways and print a error message to the output console instead of stopping the simulation.

Printing the error code with a little bit of information where, when and with which FlowItem the error occurred is not a problem.

But when I use the moveobject command, the FlowItems which I moved with the command remains in the queue and don't get processed after all the regular FlowItems have been processed.

I assume this is because there was no real incoming event in the queue, when I moved the FlowItem by command.

How can I work around this problem?

Thank you guys in advance!

I am trying to use the rail API when two networks exist.
one network is used for normal transporters and one as rail.

I cannot find out how to tell the railAPI which node is the start/first node of a railway.
Did I understand correctly that it only assumes there is one network which is dedicated to the trains?

I am looking at a situation where I have two source ->processor -> sink sequences and a forklift assigned to each, but only one operator to operate each forklift on the on-demand basis.
The straightforward solution is the coordinated task sequence from the tutorial but I really hope to come up a more elegant one for two reasons:
1) I have multiple queues and I really do not want to create copies of the same task sequences for each queue or even a call to the external function.
2) Ideally I would like to have this arrangement reusable.
So herein lie my questions:

Is it possible to delegate the creation of the custom task sequence to the dispatcher, get the source/destination data from the dispatched task sequence in the dispatcher's OnReceiveTaskSequence and create a new custom task sequence from there?

Is it possible to encapsulate this functionality in a "special kind of forklift" so it can be dropped into the model, connected to the operator and will start acting like a normal forklift that works only when there is someone available to drive it?

Thank you!
