Can you show your decide module using ARENA for the following situation? As soon as the cell phones are received, they undergo an initial inspection to determine what type of repair needs to be done, or if the cell phone can be repaired at all. It turns out that 80% of the phones cannot be repaired at all, and thus, they will be rejected for repair, 5% of the phones require a screen replacement, and 15% of the phones require a battery replacement.

Customers arrive at a cellphone repair shop and bring cellphones to get repaired. Customers arrive according to an exponential distribution with a mean of 30 minutes. Sometimes, customers bring more than a single phone with them, in fact, 5% of the time, they bring 1 phone, 5% of the time they bring 2 phones, and 90% of the time they bring 3 phones, that is, the number of arrivals follows a Discrete Empirical distribution of the following form DISC(0.05, 1, 0.1, 2, 1, 3). As soon as the cell phones are received, they undergo an initial inspection to determine what type of repair needs to be done, or if the cell phone can be repaired at all. It turns out that 80% of the phones cannot be repaired at all, and thus, they will be rejected for repair, 5% of the phones require a screen replacement, and 15% of the phones require a battery replacement.
