a)
Summary Introduction
To determine: D promises customers that its network has a 90% reliability. Calculate the reliability of the network. Are customer complaints justified?
b)
Summary Introduction
To determine: D is considering adding nodes to its network structure so that each of the current nodes is “backed up” by a lesser node with 80% reliability. What is the reliability of the new network?

A furnace thermostat has a constant failure rate of one failure per 25 months and a mean time to repair of four hours.,
Please answer last 3 subparts
a) What is the thermostate reliablity after 12 months? After 24 months? After 36 months?
b) What is the availablity?
c) Should a design team try to streamline the repair process to reduce the MTTR? Explain. Does the location of the furnace matter?
d.) Given a reliability target of 99 % ,what combination of mu,µ,and time ,t
,values will suffice? You must do at least two different combinations of µ and t
"High reliability can be achieved in a product without having high reliability in the component parts. In fact, any reliability target, no matter how high, can be achieved with only mediocre parts, so long as enough of them are present." Discuss; an example may help.
A University Web server has 5 main components, each with the same reliability. All 5 components must work for the server to function as intended. If the University wants to have a 81 percent reliability, what must be the reliability of each of the components?
