This paper presents a simulation study on the behavior of 95% bootstrap confidence interval for estimating bullwhip effect. Effects of sample size, autocorrelation coefficient of customer demand, lead-time, and bootstrap methods on 95% bootstrap confidence interval of bullwhip effect are presented and discussed.
This paper develops a multiobjective programming model for the optimal allocation of passenger train services on an intercity high-speed rail line without branches. Minimizing the operator's total operating cost and minimizing the passenger's total travel time loss are the two planning objectives of the model. For a given many-to-many travel demand and a… (More)
