Bus systems are naturally unstable. Without control, the slightest disturbance to bus motion can cause buses to bunch, reducing schedule reliability. Holding strategies can eliminate this instability. However, the conventional schedule-based holding method requires too much slack time, which slows buses. This delays on-board passengers and increases operating costs. This paper studies a family ...

The purpose of this study was to investigate how fast three-dimensional (3D) MR image quality is affected by breath-holding and to develop an optimal breath-holding strategy that minimizes artifact in the event of an incomplete breath-hold. A computer model was developed to study variable-duration breath-holds during fast 3D imaging. Modeling was validated by 3D gradient-echo imaging performed ...

This paper studies a single-product supply chain, in which the supplier needs to manage its own inventory to fulfill requests from a set of heterogonous retailers. The retailers’ requests are determined by the supplier in a fashion of vendor-managed inventory (VMI). Under a VMI arrangement, the supplier agrees to pay all the order setup costs and a portion of unit holding costs for the retailer...
