Using the Deterministic EOQ Formula in Stochastic Inventory Control
给出了当需求随机时，使用确定性EOQ公式作为启发式解所导致的相对成本增加的一个改进上界（约0.1180），并讨论了该上界何时是紧的。
This note gives an improved bound (√5 − 2)/2 ≈ 0.1180 for the relative cost increase when using the deterministic EOQ formula as a heuristic solution when demands are stochastic. We also discuss under what circumstances this bound is tight.
