An Alternative Approach to Alternative Routes: HiDAR Technical Report
Alternatives to a shortest path are a common feature for modern navigation providers. In contrast to modern speed-up techniques, which are based on the unique distance between two locations within the map, computing alternative routes that might include slightly suboptimal routes seems a way more difficult problem. Especially testing a possible alternative route for its quality can so far only ...
متن کاملZ Alternative Routes in Road Networks
We use web-based and autonomous navigation systems in everyday life. These systems produce driving directions by computing a shortest path (or an approximation) with respect to a length function based on various measures, such as distance and travel time. However, optimal paths do not necessarily match the personal preferences of individual users. These preferences may be based on better local ...
متن کاملFlights Alternative Routes Generator by Genetic Algorithms
This paper present a new Air Traffic routes generator based on Genetic Algorithms. Due to the traffic growth, direct (and near direct) routes are more and more congested and there is a real need for spreading the traffic on new alternative routes. Those routes have to be different from several operational criteria and must not generate too much extra-distance compared with the direct route. To ...
متن کاملExploring alternative routes for oxygen administration
BACKGROUND Hypoxemia may compromise cell metabolism and organ function. Supplemental oxygen (O2) at high concentrations may prove ineffective, and issues relating to hyperoxia, barotrauma, mechanical ventilation, and extracorporeal oxygenation are well documented. Old reports suggest the potential safety and efficacy of alternative routes for O2 administration, such as intravenous or intestinal...
متن کاملDeveloping a cellular manufacturing model considering the alternative routes, tool assignment, and machine reliability
The cell formation (CF) is one of the most important steps in the design of a cellular manufacturing system (CMS), which it includes machines’ grouping in cells and part grouping as separate families, so that the costs are minimized. The various aspects of the problem should be considered in a CF. The machine reliability and the tool assigned to them are the most important problems which have t...
