Arrival Style
This is used to specify the way that the source creates flowitems.
Inter-Arrival time - After a set period of time, the source creates one flowitem. This repeats until the model is stopped.
Arrival Schedule - The source follows a table that defines when flowitems are created, how many there are, and what itemtypes are assigned to them.
Arrival Sequence - The source follows a table that defines what order flowitems are created in. Flowitems are created as fast as the source can move them downstream.
FlowItem Class
This is used to define what class of flowitem the source will create. To view and edit flowitem classes, select Go to Flowitem Bin... in the drop down, or go to the ToolboxFlowitem Bin.
Inter-Arrivaltime Usage
These fields define how the source creates flowitems when inter-arrival time is selected as the arrival style.
Arrival at time 0 - If this is checked, one flow item will be created at time 0. The next will be created at the end of the first inter-arrival time.
Item Type - Flow items that are created will be assigned the itemtype defined here.
Inter-Arrival time - A function that returns the amount of time the source should wait before creating the next flowitem.
Arrival Schedule/Sequence
These fields define how the source creates flowitems when Arrival Schedule or Arrival Sequence is selected as the Arrival Style.
Repeat Schedule/Sequence - If this box is checked, the schedule or sequence will continually repeat itself until the model is stopped. In the case of a schedule, the arrival defined in row 1 will occur 0 seconds after the time defined for the arrival in the last row. This means that the arrival time for the very first row of the table is only used once for a given simulation. Note that this initial delay can be used as a warm-up period. If you would like to specify an interval time between the arrival time of the last row and the arrival time of the first for when repeated, then add another row to the end of the table and specify a quantity of 0.
Number of Arrivals - This specifies how many rows are in the arrival table. Change the value in this field and hit Refresh Arrivals to update the table view.
Number of Labels - This specifies how many columns are in the arrival table. Change the value in this field and hit Refresh Labels to update the table view. Additional columns will be added for labels and their initial values that will be added to the flowitems when they are created.
Add Table to MTEI - This buttons adds the table as a row in the Multiple Table Excel Import.
ArrivalTime - (Arrival Schedule only) This is the time in model time units that the arrival will occur.
Item Name - Specifies the name of the flowitem when it's created.
ItemType - The itemtype the flowitems will be given when they're created.
Quantity - This number specifies how many flowitems will be created during this arrival.
Labels - This specifies all labels that will be added to created flowitems and their initial values.
