Display Time In System

Hi

We used to use VisualTool to show the average staytime of a flowitem in the model. Now we have the TimeInSystem as tracked variables for each flowitem. Besides using code to work out the average TimeInSystem, is there a simpler way to show that in the Dashboard using Text?

Simpler means I don't have worked out myself, but there is an available variables that I just have to choose just as Average stay time.

Thanks

I've added an item to the development list to create Min, Max, and Average Tracked Variable stats for the Dashboard.

In the mean time, you could use a Model Documentation dashboard stat object and display the calculated average of the tracked variable. Attached is a model that shows how this can be done.

You can find the average of a tracked variable by using the getdatastat() command like this:

treenode timeInSystem = node("/Tools/TrackedVariables/TimeInSystem", model());
int numEntries = getbundlenrentries(timeInSystem);
if (numEntries > 0)
     return getdatastat(STAT_MEAN, numEntries, getbundlevalue(timeInSystem, count - 1, 1));
else return 0;

Hi

I found that the export function for both TimeInSystem and QuantityInSystem is not working. Is there another way export the data?

Here's a workaround for now but only for a single tracked variable.

Make the tracked variable bundle you want to export so() (they're in /Tools/TrackedVariables) and then run this script:

string startDir = modeldir();
if (stringlen(startDir) < 4) startDir = documentsdir();
string filePath = getfilebrowse("*.csv", "Comma Separated Format", "", startDir, 1);
treenode tvar=so();
exportdataset(tvar, filePath, DATATYPE_BUNDLE);
fileopen(filePath, "a");fpr();
fpt(concat("End of ",getname(tvar)));fpr();
fileclose();

Just realized another way of capturing the data is using the Experiment but we need to have the TimeInSystem Vs Time setup in the Dashboard. At the Experiment, we choose that as the PFM using average. That should provide us with the Average TimeInSystem.

Any comment?
