Table 3- Failure Rates of Transistors in Computers End of week Probability of failure to date 0.08 0.18 0.29 0.47 0.71 0.91 1.00 1 2 3 4 5 6 7 The transistors could be replaced individually for a cost of RO 12.000 per transistor. If all the transistors are replaced simultaneously, it would cost RO 3.000 per transistor. Any one of the following two options can be followed to replace the transistors: (a) Replace the transistors individually as and when they fail (individual replacement policy). (b) Replace all the transistors simultaneously at fixed intervals and replace the individual transistors as they fail in service during the fixed interval (group replacement policy). Find out the optimal replacement policy, i.e. individual replacement policy or group replacement policy. If group replacement policy is optimal, then find at what equal intervals all the transistors should be replaced.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
