Hi John,

Could you please upload your model? It is not clear to me where it goes wrong.

Hi Ditmar, What is your cycle time formula after you changed the model from Uniform to Lognormal / NegExp? The Uniform distribution uses (min, max); The LogNormal(mean, standarddeviation) and the NegExp(mean). Something like LogNormal(hr(Label([HourArrival], i)-1), hr(Label([HourArrival], i) ) ) slo...

Hi Ditmar, Your distribution is uniform within the hour and emperical if you look at the whole day. As a result trucks will always arrive/leave randomly but at the same time according to the daily pattern. What kind of distribution you can or should use really depends on the data / situation. I thin...

Hi Ditmar, The Histogram shows a high peak at 0 and 15 as the queue is empty or blocked most of the time. I added some some graphs to illustrate this. 1000h run gives app. 27% empty, 28% full. The remaining 45% is 0>x>10. 102 + 107 trucks / 11 hours per day is on average 19 trucks per hour. With 160...

Hi Hesam Adrang,

Could you please be more specific? What are the problems you encounter while building your model?

Hi fraceccolost, The data from the Excel sheet can be written to a table in Enterprise Dynamics with the ExcelActiveX atom. (Library Tree |> 10 Data |> 6 ExcelActiveX). To update the Source atom refer to the corresponding table cells. This method is further explained in the example model ExcelActive...

Hi Rezasoltani, Please see the attached example model. The Two-step example production line consists of a Source, a Queue, two Servers and two Sinks. Source - Trigger on exit : Each product that leaves the source gets a label: 73% of the products are marked as 'healthy'. Label([normalordefective],i)...

Hi Sven, In the attachment you'll find some model suggetions. Model components: - Arrivallist: creates every 24 hours 113 products (trucks) at once. All these trucks go directly to the MultiService atom. - MultiService: The MultiService adds a cycletime to the trucks. In this case negexp(hr(3.5)). A...

Hi svendevries, The Availability Control atom allows you to control the availability of other atoms. If an atom is set to unavailable it will stop executing the tasks for which that atom was designed. Connect the Mtbf Mttr Availability atom to the input channel of the Availability Control atom and s...

Hi mastermind12, Perhaps the Splitter atom? The Splitter atom splits a single atom into a number of atoms, and sends out a number of copy atoms through multiple output channels. The copies are exact duplicates of the original atom (including labels). The number of copies to send out of each output c...
