Get started for freeA graphics reproduction firm has four automatic equipment units but occasionally becomes inoperative because of the need for supplies, maintenance, or repair. Each Unit requires service roughly twice each hour, or, more precisely, each Unit of equipment runs an average of 30 minutes before needing service. Service times vary widely, ranging from a simple service (such as pressing a restart switch or repositioning paper) to more detailed equipment disassembly. The average service time, however, is minutes. Equipment downtime results in a loss of \(20 per hour. The one equipment attendant is Paid \)6 per hour.
Using finite queuing analysis, answer the following questions:
C. What is the average number of units being serviced?
