Accuracy of Vaccination Dates Reported by Immunization Providers in the National Immunization Survey
1. Introduction Immunizations are among the most effective public health interventions to prevent disease and death. Currently, vaccine-preventable diseases are at their lowest level in U.S. history (1, 2). The availability of a large, high-quality, and reliable population-based immunization database provides a unique opportunity to monitor vaccination coverage. The CDC-sponsored National Immun...
متن کاملSingle-machine scheduling with release dates, due dates and family setup times
We address the NP-hard problem of scheduling n independent jobs with release dates, due dates, and family setup times on a single machine to minimize the maximum lateness. This problem arises from the constant tug-of-war going on in manufacturing between efficient production and delivery performance, between maximizing machine utilization by batching similar jobs and maximizing customers’ satis...
متن کاملEarliness-Tardiness Scheduling Around Almost Equal Due Dates
The just-in-time concept in manufacturing has aroused interest in machine scheduling problems with earliness-tardiness penalties. In particular, common due date problems, which are structurally less complicated than problems with general due dates, have emerged as an interesting and proliic eld of research. We prove that so-called almost common due date problems, in which the due date d j and p...
متن کاملScheduling Trains and Containers with Due Dates and Dynamic Arrivals
We consider the problem of scheduling trains and containers (or trucks and pallets) between a depot and a destination. Goods arrive at the depot dynamically over time and have distinct due dates at the destination. There is a fixed-charge transportation cost for each vehicle, and each vehicle has the same capacity. The cost of holding goods may differ between the depot and the destination. The ...
متن کاملSingle Machine Scheduling with Distinct Due Dates under Fuzzy Environment
Single machine, distinct due dates, early/lately machine problem and fuzzy environment closely models the situation faced by ‘Just In Time’ manufacturing. The objective of this paper is to sequence the jobs on the machine, so that the total penalty cost be minimum. This cost is composed of the total earliness and the total tardiness cost. An algorithm is developed here to minimize the total pen...
