This paper presents a simulation-based comparative analysis of several of the more prominent inventory lot-sizing models under multivariate stochastic conditions. Specifically included as stochastic system variables are lead time variation, demand forecast error, and inflation rate. The six rules, classic EOQ, periodic order quantity, least unit cost,(More)
Van Slyke introduced simulation as a method for the analysis of project networks in 1963. Since that time many new simulation procedures have been developed and/or adapted for use in project management. The purpose of this paper is to review the traditional simulation procedures that have been applied to project management and to present and discuss new(More)
Videotaped scenes of everyday events were shown to hospitalized abused and nonabused children and to a nonhospitalized peer group. The children's heart rates were taken as they viewed the scenes and they responded to questions about the content of the scenes. The hospitalized children reacted to the scenes with a larger decrease in heart rate than did the(More)
