In the dashboard, is there a chart that shows me the productivity of my model? Or how do I know that?

@Alejandro Cevallos

You are going to have to explain what you mean by "productivity of my model". I don't know what that means and I'm not sure what information you are wanting to get. If your model gives you the information that you are seeking by building it, then I would think it was a productive model.

Alejandro,

The Dashboard has many options for display charts such as Content vs Time, Average Staytime, Output per Hour, and others. There are also other ways to get data from your model but, as Jeff mentioned, it depends on the information you're looking to get. It's also a different matter if you're trying to see how you can improve a certain performance within your model. If you give us more specifics we'd love to help you find the right tools for what you need.

Update: below is an example model of one way to find the productivity of a model (output/input). I've set a tracked variable called "Input" that is incremented every time a flowitem is created, and another called "Output" that is incremented every time a flowitem enters the sink. I used simple custom code in a text activity to display this calculation.

Some other ways you might go about this are with Zone statistics in process flow, statistics created on fixed resources, etc.

You'll also see that I set up an experiment to see the effects that using a transport from the source makes on the model input and output (our tracked variables).

productivity = output / input is a typical financial data. Since Flexsim doesn't collect this kind of data you have to implement it by your own. Each time when you invest money in the model of any kind you increase a label value on a token, on an item or on an object. Each time when an item goes into a sink you set a financial income or a financial valued price for this product and calcalute the productivity.

There are different developments on some discrete material flow simulators on the market. Nowadays the new data collection is on electricity consumption. Maybe in a few years the aim is set towards financial data.

My intention was to know if there is a chart in the dashboard that tells me the Output / Input (Productivity), because I need to compare two models that I developed.

Thanks for your comments.

@Alejandro Cevallos This sounds you have a calculation, resulting in a number over time ( for instance every time your input increases or your output decreases. This can be done perfectly with a tracked variable. Options to manipulate those are present in every entry and exit trigger and there are many graphs that can deal with a tracked variable.

[adrian_haws]

@Alejandro Cevallos Were you able to find the solution you needed? We can send you an example model of how to get this information, such as a tracked variable, dynamic text display with code, etc.

[alejandro_cevallos]

Adrian, I would greatly appreciate if you could send me a model example of how to get this information

[adrian_haws]

@Alejandro Cevallos I've added this sample model to my original answer.

[alejandro_cevallos]

Adrian, I tried to put in my model the "variable tracked" as it was in your simulation but it did not work properly. Enclosed is my simulation with the purpose you can help me.

In my case I have three sources and for that reason I decided to put in the queue (Cola NN) the trigger "Increment ChooseVariable" (Input). This will detect all incoming products of the three sources as total input.

@Alejandro Cevallos That's because there are currently no Tracked Variables called "Input" or "Output"-you need to create those. You do that by going into the green plus icon in the Toolbox and selecting Statistics->Tracked Variable. Then give it a name and a type (in this case the type would be Cumulative). Now you will have a reference to the tracked variables in your triggers and dashboards.

Thanks Adrian. It worked very well.
