IAdvanced Manufacturing Systems Engineering Assignment 2 Queueing Network Models Names:
- Consider a manufacturing system with a single station with three servers. Jobs arrive following an exponential distribution with a rate of 7 jobs per hour, while the service rate of each of the three servers follows an exponential distribution with a rate of 10 jobs per hour. If the total number of jobs that can be in the system at any time is 5, use this information to answer the following questions.
- Draw and label a state space diagram, showing all states and the rates of transition between states.
- Write a complete set of balance equations
- Solve your system of equations to determine the long run probability of the system being in each possible state
- What is the average number ofjobs in the system at any point in time?
- What would be the effect on the state probabilities if the arrival rate reduces to 4 jobs per hour?
- Consider a simple barber shop with one (1) "service chair" and two (2) "waiting chairs." Customers to this barber shop arrive with exponential arrival events depending on the state of the system. If the system is empty, customers arrive at rate m. If there is a customer in the chair, but no one in the waiting chairs (a total of one customer in the system), the arrival rate slows to 0.8K. If there is one customer in service and one waiting (a total of two customers in the system), the arrival rate slows further to 0.6m. Once there are three customers in the system, an incoming customer decides to turn away.
