Hello,
I have a model where the ASRS retrieves items from racks and puts them onto a conveyor after a defined dwell time has expired. Now I would like to implement "rush orders" - I have already defined their dwell time as 0s, but when other items in the shelf also have arrived at 0s they sometimes get taken before my rush orders. How can I prioritize the rush orders without influencing the order of the other items in the task sequence?
FlexSim version 7.5.4 was used.
@Julia Huuk You can use the Priority area in the Rack / Flow Tab Proprieties. Now the ASRS priority will be the Rack unload parts instead of load parts in the queue. For more complex task sequence you can use the Process Flow tool.
You can set diferent Rack Dwell Time for each Itemtype or label in the Values By Case option.
I hope that this information can be helpfull for your model. Regards!
@Rodrigo Lamas Thank you for your answer. I have already used these options in FlexSim, but I would now further like to set the priority for one specific item type to be unloaded before all others.
The scenario is the following:
- The rack gets filled with items which all have a defined dwell time. Once their dwell time expires they get unloaded. This works fine in my model.
- After a given time a rush order gets created and put into the shelf. Now I would like these specific items (their dwell time is already zero) to be unloaded before all other items that are due to be unloaded as well.
The Process Flow Tool you mentioned - how does that work and where may I find that?
Thank you again.
@Julia Huuk Please see this question about a logic using Process Flow and List concepts in Rack. I hope that can be helpfull for your model. Regards! https://answers.flexsim.com/questions/21546/how-to-send-items-to-multiple-fixed-resources-in-p.html
@Julia Huuk Did this answer your question or do you still need help?
Thanks for checking in again, actually we decided to live with the mistake in the model because it just took up more time than we could invest to solve the problem. I had never worked with the process flow tool before and have to learn more about that feature before being able to apply it.
