Define "crash priority" orders as those that must be completed as soon as possible

$($no waiting or delay is allowed$).$ Will a crash priority order cause disruption to current order$($s$)$

that is$/$are already being processed in the following cases? $($Disruption means the progress of

current orders is affected as they have to give way to the crash priority order.$)$ For simplicity,

assume there is only one order currently in the process.

a$.$ The only current order is in the cooling stage;

b$.$ The only current order has been baked for $4$ minutes;

c$.$ The only current order just entered the oven;

d$.$ The only current order is in the mixing stage.

Define pending orders as all orders you have received but not finished yet $($some

could be in the process already, while others are waiting to enter the process$).$ Suppose the

number of pending orders is the only information you have $($i$.$e$.,$ you do not know the status

of any of the pending orders$)$ when someone calls in to place an order.

a$.$ Assume that the process is in a steady state. Given that you know the number of

pending orders and the CT of the process, what is a VERY SIMPLE way for you to

quickly estimate the time to complete the caller's order?

b$.$ Is this estimate always sufficient for you to complete his order? If not, how much more

time should you add to the estimate so that you can certainly finish his order within

this augmented estimate? $($Hint: the process may not be in a steady state when you

receive the new order. Consider the worst$-$case scenario. Keep it simple, do NOT

consider any possible disruptions or burnt cookies.$)$
