Re: Batch size server

Hi Eveline, in addition: The conclusion of Harry is correct. For barrels of type 2 (blue) the second evaluation result in a 0. As a result no copy is made and just the original will move on. An easy way of writing the Batchrule code is : Cell(1, Label([barrel], i), refkgs_barrel) Here the label valu...

Re: Assembler - flowtime

Hello Eveline, Attached an example of what I expect you are looking for. I used your model as basis but added some control functionality to determine when an output should be opened (on reset everything is closed). The order or recipe atoms (yellow or purple) define the BOM. The table Flows the seco...

Re: Random assignment of work elements to workstations in an assembly line

Dear Amir Ebadi, We have some doubts whether we have understood your question well. Is it correct that you want to model an assembly line using the takt time principle ? So there are several working stations where elements are assembled to the main product. Each station must perform its task within ...

Re: Modelling a Distribution Centre

Hi Darek, In the Advanced transporter you find a tab called Offset. In it you can define the offset per direction for picking or placing. As you just want to pick you only need to define an X and Y offset for picking. Offsets are relative to the left-upper corner of the atoms connected to the nodes ...

Re: Modelling a Distribution Centre

Hi, I used your approach (layout and table B) to demonstrate the functionality. See attached model. One could use the triggers to write all code. I chose to use a blank atom and named it 'OrderControl'. It has some code on it to deal with the 2 events: event 1 is a next pick line; event 2 is complet...

Re: data recorder

Dear Mia, I had a look into your model to try to help you with the data recorder. What I noticed is that all Data recorders of an 'Analysis Stop time' of hr(8). This means that they stop recording after 8 hours. For none of the recorders an object has entered the Data recorder, then the shop opens a...

Re: StatusMonitor for Portal Crane

Hello Eike, It is possible to use the Status Monitor Atom to show the distribution of statuses of a portal crane. However the Portal crane atom consists of a several layers: an element for the X-direction, one for the Y-direction and the Crane grabber (T136-crane). When you connect the input channel...

Re: Modelling a multi variant pull system?

Hi Dominik, About modeling with larger numbers of data: instead of using lots of ‘lf – then – else‘ commands it is often easier to use the CASE statement. Even better is using tables. It is very flexible and reduces the amount of coding. I attached a model 1B to demonstrate this. In the table I used...

Re: Modelling a multi variant pull system?

Hi Dominik, My remark about ranking the orders was related to your question how to reorganize the process in order to meet the required delivery dates. There are several options for ordering and priorities. In some cases simple methods are sufficient. For example when you want to arrange products in...

Re: Can atoms block eachother in ED?

Hi, What you describe is in my opinion collision detection. A method for collision detection using agents which communicate with each other and interact is very complex in discrete event simulation. This is also not available in standard ED. One could use extensive programming or an external module ...
