The issue related to the assigned item

j08j — Mon, 06 May 2024 14:38:26 GMT

[ FlexSim 24.0.2 ]

I want each slot to store only one item. I referenced this question. Here's my code. How can I modify it to achieve this?

source2.setProperty("Triggers.OnCreation", "Object current = ownerobject(c);\n\
Object item = param(1);\n\
\n\
Map dimensions = current.outObjects[1].getProperty(\"Dimensions\");\n\
int Bay = dimensions.NumBays;\n\
int Level = dimensions.NumLevels;\n\
int Slot = dimensions.SlotsPerBay;\n\
\n\
int i = duniform(1, Bay, 1);\n\
int j = duniform(1, Level, 1);\n\
int k = duniform(1, Slot, 1);\n\
\n\
Storage.Slot slot = current.outObjects[1].as(Storage.Object).getSlot(i, j, k);\n\
if(slot.as(Storage.Slot).slotItems.length < 1) Storage.Item(item).as(Storage.Item).assignedSlot = current.outObjects[1].as(Storage.Object).getSlot(i, j, k);\n\
");

model.fsm

Thanks.

I made the following modifications, but there still exists a situation where multiple items are placed in a single slot.

source2.setProperty("Triggers.OnCreation", "Object current = ownerobject(c);\n\
Object item = param(1);\n\
\n\
Storage.Item itemStorage = Storage.Item(item);// insert item into storage system\n\
Storage.Slot slotRack = Storage.system.findSlot(\"WHERE slot.slotItems.length < 1 ORDER BY slot.levelID ASC\");// place item by level\n\
itemStorage.assignedSlot = slotRack; //assign storage system item to slot\n\
");

You create a model by code. Then it is a timing issue. If more sources are able to fill rack slots then timing is causing a crutial impact when and which data is present for other model objects. If you are familiar with Porcess Flow, you know that you need to add breath activities to resolve pending data into a state that it can be evaluated. In time units of a model run you are still in time 0, but the order of inserted and executed code has different impact on getting results successfully. Please test on your own, which order of inserted codes leads to a successful model.
