. 2. Explain why a product or system might have an overall reliability that is low even though it is comprised of components that have fairly high reliabilities. 4. A product engineer has developed the following equation for the cost of a system component: C _ (10 P ) 2 ‚ where C is the cost in dollars and P is the probability that the component will operate as expected. The system is composed of two identical components‚ both of which must operate for the system to operate. The engineer

Reliability is a trait that I look for in others and especially hope to show myself. As a computer scientist‚ I write programs in which I collaborate with other programmers who could at any point sabotage or steal what we are working on. These individuals must possess the trait of reliability in order for the project to be completed or otherwise we would never succeed. Many people can see myself as an individual they can trust with getting something done for them or helping them in whatever way possible

the reliability data for each component. • The pump has the following data: scale factor α = 8000 hours and shape factor β = 1. • The motor has the following data: scale factor α = 9000 hours and shape factor β = 1‚8. Based on these data: • calculate the reliability of pump and motor at time t = 1000 hours; • identify the stage of the life cycle of pump and motor; • evaluate the reliability at time t = 1000 hours of a system made by one pump and one motor (system A) and the reliability of a

deficiencies. The actual quality of a product is a vital part of a consumer’s perception of a good or service. Quality can describe any attributes in a set of characteristics that satisfy or disappoint the customer‚ including usability‚ reliability‚ and durability. An actual product can influence a consumer’s perception on its quality‚ but in the end‚ particularly with non-durable goods‚ a customer’s actual experience will determine their perception of quality.

Submitted to Professor. Xie Lu Yang School of Mechanical Engineering and Automation Northeastern University Abstract This paper provides an overview and guideline on the use of Failure Mode and Effect Analysis (FMEA) for ensuring that reliability is designed into typical manufacturing equipment. FMEA is a very important method which should be employed in companies for an engineering design‚ production process‚ and new product in preproduction and production sphere in product life cycle.

The Relationship Between Relevance and Reliability Accounting information provided by accounting entity must reach a certain quality standard‚ so that it can meet the users’ needs of accounting information. Financial accounting information quality has four basic characteristics‚ can be understandability relevance‚ reliability and comparability. Two of the greatest impacts on the accounting of the main accounting policies are relevance and reliability. When we compare and contrast any two subjects

It is a technique to resolve potential problems in a system before they occur. It is most widely used reliability analysis technique performed between the conceptual and initial stage of the detailed design phase of the system in order to assure that all the potential failures have been considered and the proper provisions have been made to eliminate these failures.
