Consider a stick of length 1. Let XI and X2 be independent random variables denoting two points n the stick at which we break the stick into three pieces. We assume that X1 and X2 are uniformly distributed over the interval

Lecture Outline Introduction to queuing systems Conceptual representation of queuing systems Codes for queuing models Terminology and notation Little's Law and basic relationships Birth-and-death processes The M/M/1 queuing system State transition diagrams Steady-state probabilities

Countries identified as First-World are listed in the text. Some approximations attend the calculations, and the denominators are rounded off to the nearest half million. The mortality-risk difference between domestic and international flights in the first-world is not statistically significant: If major fatal crashes arise under a Poisson process at rate ) per million flights, then the observed

风险概念定义: (1)风险关注未来将要发生的事情; (2)风险涉及改变; (3)风险涉及选择本身所包含的不确定性。 当没有办法消除风险,甚至连试图降低该风险也存在疑问时,这些风险就是真正的风险了

有关的活动所导致的成本。预先设定成本基线 ,标识降低成本的机会 质量成本可以被划分为与预防、鉴定及失败相 关的成本 预防成本:质量计划、正式技术复审、测试设 备、培训等。 鉴定成本:过程内和过程间审查、设备校准和 维护、测试等 失败成本:包括内部失败成本和外部失败成本 内部失败成本:产品交付用户以前发现错误而 引发的成本
