Tabu search for bus and train driver scheduling with time windows
… would not be prohibitively large. Moreover, windows of relief opportunities (WROs), which provide ranges of opportunities for relieving drivers, are beyond the capability of being handled by the existing systems. The usual practice is to consider one, sometimes two, discrete times within each …

Time Windows for Indexing Language Comprehension in Adults With and Without Aphasia
Time-course analysis on eye-tracking data has been proven useful by previous researchers who have studied language processing of spoken and written input. Researchers found that language processing is a time-locked activity that can be based on eye movements. However, the ideal time windows for …

Leveraging machine learning to solve The vehicle Routing Problem with Time Windows
The Vehicle Routing Problem with Time Windows (VRPTW) has been widely studied in the Operations Research (OR) literature given its increasingly widespread applications, ranging from school bus scheduling to packages delivery. In the last decades, and in large part due to the surge in e-commerce and …

Using the Timeline Followback to Identify Time Windows Representative of Annual Posttreatment Drinking
Using 12-month post treatment Timeline Followback drinking reports, data extrapolated from shorter time windows (e.g., 1 month, 6 months) were used to estimate total annual drinking. The objective was to determine whether data from a shorter time window would provide an estimate of annual drinking …

An Adaptive Large Neighborhood Search Heuristic for the Inventory Routing Problem with Time Windows
… can only receive deliveries during a window of time (6 am to 6 pm). The retail chain is seeking more efficient alternatives to this policy, as measured by total transportation, inventory holding and lost sales costs. More specifically, the goal of this research is to determine the optimal timing …

Optimization models and algorithms for large-scale, capacity constrained pick-up and delivery problems with time windows
Major package delivery companies employ hundreds of thousands of people, generate billions of dollars in revenues and operate very large fleets of ground vehicles ranging from custom- built package cars to large tractors and trailers. A crucial point for the profitability of these companies is, for …

A large-scale neighborhood search approach to vehicle routing pick-up and delivery problem with time windows under uncertainty
… problem with shipment pick-up and delivery with time windows (VRPPDTW) is one of the core problems that is addressed by a package delivery company in its operations. Most often, this problem has been addressed from the point of view of cost-cutting, to achieve the lowest cost possible under a …
