Transporter assignment sequence based on GlobalTable (Thru ProcessFlow)

Hi there, i'd like to ask how to assign the transporter to:
1. load specific item for 100 amount only (1 batch = 100 amount), then after it loaded
2. deliver the item to specific location (from-to) based on GlobalTable
3. back to point 1. untill the assignment sequence from GlobalTable is finish.

Currently, I've implemented ProcessFlow and modify my model based on tutorial:
1.Replenish queues by itemtype

2. How to make the forklift transport more than one item per time

Here's the overview of my model:

  • 4 kind of item (J1, J2, J3, J4)
  • 4 different machine
  • 1 Transporter
  • Jobshop type


The model is Jobshop and it's running successfully, i assign every specific item's (J1, J2, J3, J4) route based on "Flow: Output: Port by Case".

My objective is to apply the production scheduling (EDD/SPT/etc) which has been translated into GlobalTable's sequence. Therefore only by the Transporter follow the GlobalTable can apply this objective, since the item's routes has been set directly in model.

Here's the GlobalTable:

Details:

  1. Type: Item's type that will be transported by Transporter, (Value: 1=Job1,..,4=Job4 (Label has been set in the Source))
  2. From: The beginning point of the Transporter
  3. To: The destination point of the Transporter

The Transporter will work based on the current Row of the GlobalTable (Label:Row) starting from the first row. If the work has been done, there will be increment of Label:Row, then the transporter will work on second row, and every work in regards of only carrying 100 amount of specific item or wait. Here's my flexsim model.

@Arimba W

Take a look at this model, the transporter stops at row 10 since from Row 1 to 10 there are 3 times items are placed in M1, but 4 times it requests a movement of items away from M1.
