A factory receives orders for $3$ different products $($A$,$ B$,$ C$).$ Orders arrive according to an exponential distribution with a mean of $1$ hour. Of the incoming orders, $40\%$ are for product A$,35\%$ are for product B$,$ and $25\%$ are for product C$.$ Orders are processed on a single machine line. Product A is high priority, product B is medium priority, and product C is low priority. The processing time for product A follows a uniform distribution between $40$ and $50$ minutes, for product B it follows a uniform distribution between $20$ and $30$ minutes, and for product C it follows a uniform distribution between $15$ and $25$ minutes. The factory operates with $3$ machines. Create an ARENA model that tracks the time products spend in the process both overall and by groups, and that takes into account each capacity and priority rule.
