Periodic Statistics

 by dsturrock ¦  Mon Sep 25, 2017 4:43 pm ¦  Forum: SI Shared Items ¦  Topic: Periodic Statistics ¦  Replies: 0 ¦  Views: 118

Ever want to track statistics periodically, like by hour, shift, day, or week? I created this pair of objects for a customer about a year ago, then forgot to do anything with it. Perhaps others will find this to be useful. The solution is two objects, one for states and one for tallies, that allow y...

Re: Track State Statistic in Experiment

To extend the above example, the Monitor element would fire an event and/or trigger a process. In that process you would need to have a Tally step that records an observation on a TallyStatistics element.

If you had posted this in the Simio Insiders area I would have included a screen shot.

Statfit does that automatically if you select Simio as the Export Application.

The meaning of Simio's parameters are well described in help and consistent with industry standards. It appears that you may not be choosing the correct export application in Stat::Fit. When I choose the default export I see 3 parameters, but when I choose the Simio application it shows an expressio...

The best choice is to use the Task Sequences option of the Server.

If you want a solution to a problem, it is best to post your questions inside Simio Insiders where we can post files with the response. I tried what I think you are doing and it worked fine for me, aside from the fact that the expression you used creates 1 arrival per event between 6- 11 am, 2 arriv...

They are similar statistics except that the first statistic looks at the resource state as it changes over time ... successive "busy" states with no state change between them (e.g. there is no idle time) are considered to be a single busy state. For the second statistic each entity is recorded separ...

A slightly more efficient and easier to read version of the same logic:
Math.If(((DateTime.Hour(TimeNow)>6)&&(DateTime.Hour(TimeNow)<=10)), (1-p1), 0 )

Or shorter:

There are many ways to do this. In that same SimBit, if you look into the definition of MyVehicle, near the bottom you will find a process named StartChargingBattery. One way is to simply change the properties of that Decide step.

Can the Cranes object in the Extras library be sub-classed in the same manner as the Bridge and Underhung cranes? I am running into issues with 3-crane deadlocks in the Cranes object which is why I was looking for something else which could be sub-classed and modified. Yes they can. But perhaps you...

Yes, I believe it is. If you do not need the "underhung" ability to move cranes from one bridge to another, then I suggest that you instead use the Cranes object in the Extras library. This newer library is simpler, has a few more features, and is more robustly tested.

In 9.148 and later we introduced Reneging functions that make this easier. And one of our SimBits is very close to your request. Search the help or SimBits for "Reneg"

Create a Monitor on the state value, and every time it goes to zero Tally an observation.
