Re: Time varying appointment arrivals

Add a 'NumberArrivals' data column to the data table that is defining the arrival schedule. For example, define your arrival schedule table like this: SomeArrivalTableName ArrivalTime NumberArrivals 8:00 am 5 8:30 am 5 9:00 am 10 9:30 am 8 etc. Then on the Source object, specify the Arrival Mode as ...

Re: Routing Logic Vehicle Initial Home

You can dynamically assign the 'HomeNode' state variable of a vehicle or worker object (e.g., ASSIGN: Vehicle1[1].HomeNode = BasicNode1 or ASSIGN: Vehicle.HomeNode = BasicNode1 if the vehicle of interest is associated with the token executing the Assign step). The 'Initial Node (Home)' property is s...

Re: How exactly do you use the switch control variable?

1) Add a state variable to you model that is the switch control variable. For example, add an integer state variable named 'MySwitchControlVar'. 2) Specify the variable that you created as the Switch Control Variable on the Flow Node. 3) On each of the possible outbound links that can be chosen, in ...

Re: Randomrow function for a table with foreign key relation

A possible rough approach: 1) Add a data table. Let's name it 'Node_In_KeyTable' table. This table has a single column named 'Node_In' of type Node property (to take a node name). Set that column to be a Key column. 2) Add another data table. Let's name it 'Node_Out_ProbabilityTable'. This table has...

Re: Transportation Library

Auto destroy is a good idea. Just one thing on the filler to keep in mind, the source tank may have a capacity greater than or less than the entity being filled. Important to test fringe conditions. Mark, just an FYI that in Sprint 102, the following objects in the Flow Libary: Tank ItemToFlowConve...

Re: Randomrow function for a table with foreign key relation

Just a note that in Simio Sprint 102 software, the TableName.PropertyName.RandomRow function will have been fixed to respect primary-foreign key relationships. Thus, if the executing token or associated object as a reference to a selection set into the table, then the 'RandomRow' function will retur...

Re: Transportation Library

Mark: Specifically for the Flow Library Filler & Emptier objects, what I will probably do is add something like a 'Stop Early Event' option, where you can optionally specify to stop the filling or emptying operation early if some specified event occurs. Then in the Filler for example, you could spec...

Re: Transportation Library

Mark, when you replied to 'Glen' did you mean me? We have a 'Glen Wirth' and then me (Glenn Drake!). Small company but they have to hire two Glen(n)s just to occasionally confuse us ha ha. Totally separate note, today I looked at that possible issue with using Filler and the Emptier objects in the F...

Re: Transportation Library

Interesting pick-up on this one Mark. I actually think the tanker is correct and the standard objects are wrong. I have worked on systems before where both volume and weight have been constraints depending on density. The property design of the Flow Library Tank object, for user simplicity, assumes...

Re: Transportation Library

how do you change the priority of the entity that is flowing Just a note that in Sprint 101, the Flow Library Tank object has been enhanced to provide a 'New Inflow Entering' add-on process trigger as well as new built-in 'On New Inflow Entering' state assignment options. The 'New Inflow Entering' ...
