  • The long-term average number of customers in a stable system L is equal to the long-term average arrival rate, λ, multiplied by the long-term average time a customer spends in the system, W , or: L = λ W 即在一个稳定的系统中长期的平均客户数 L 等于长期的平均到达率 λ 乘以一个客户在系统中花费的长期的平均时间 W 。
  • 任务完成周期 (Cycle Time)= ( 正在同时处理的任务数 ) / ( 平均任务完成率 ) 。 (在稳定的(即满负荷)系统中,到达率与完成率是一样的。好比在餐馆,要有一桌走了才能进下一桌的人。) 扩容, ROI 队列存在于产品级别的系统,团队级别的系统,开发或测试的系统
