Problems

1) A MSSR system has three service types and one resource, with each service type requiring one of four available resources. Assume that each service type has a load of 0.75 but they pay differently, specially that r₁ = 1, r₂ = 2, and r₃ = 10. The system has no control.
a) What is the average revenue generated by the system?
b) How can the policy be improved?

2) A MSMR system has 1 service type and 5 resources. Supposing the rate of admission equals the rate of denial. What is the proportion of time the system is fully utilised?
