WK5: Queueing System

 

“The queuing system consists essentially of three major components: (1) the source population and the way customers arrive at the system, (2) the servicing system, and (3) the condition of the customers exiting the system” (Jacobs/Chase, pg. 223). A very personal process that I can relate these queuing system components to is when it comes to feeding my 11-month-old son. 

 

This process has a finite population, i.e. my son, and the arrival steps to his high chair is usually the same every time itâ€s time to eat. He vocally lets us know heâ€s hungry, we frantically chop up leftovers from the fridge, carry him to this chair, strap him in, and make sure his bib is on because he eats like itâ€s his last meal. His arrival rate consists of three feedings every four hours, but this time between feedings can vary considerably depending on how “cranky” he may be that day (yes, cranky is a statistical attribute to consider & track with an infant). The line structure here is rather straightforward in this scenario as it is a single channel, single phase format (Jacobs/Chase, pg. 228). 

 

Our textbook mentions once the customer is served, the customer may return as a competing candidate for service again or there may be a low probability of reservice (Jacobs/Chase, pg. 230). Unless our son finds another house or source to get his daily peas & carrots from, thereâ€s a 99.99% chance heâ€ll want to be serviced again. After heâ€s eaten, the yelling that preceded the process has faded and he leaves fairly happy.

 

If youâ€re a parent or caretaker for a young child, you very well know the process I just walked you through can go off the rails quickly. Irregardless of how much it may vary from this, itâ€s important for both my wife and I (from both a process efficiency and mental stability perspective) that we prepare his food ahead of time, we consider how well he slept last night, is he teething, and take into account many other considerations. Just like an auto repair shop servicing a car or an Apple store employee walking a customer through their new iPhone, feeding and taking care of a child requires proactive planning and understanding a few fundamentals of a queuing system helps too.
