Seating capacity

Abstract: A revenue management software system supports decisions to accept or deny requests for resource capacity (seats, rooms, volume/weight, air time, etc.) using control logic that accesses multidimensional lookup tables of price values for each resource (flight leg, hotel day, etc.). Each dimension of each lookup table corresponds to a variable that affects the value for the resource. As an example where the resource is airline seating capacity for a given flight itinerary, a two-dimensional threshold value table is employed for each flight leg in the itinerary where the first dimension specifies the current time slot and the other dimension the current number of reservations accepted (reservation level) for the flight leg. A request for a seat on the flight is accepted if and only if its net revenue exceeds or equals the sum of the current table values (i.e. the table entries corresponding to the current time and current reservation level) for each requested flight leg.

Abstract: The coupling and decoupling of trains while they are in motion is one of the research fields of the DLR project Next Generation Train. The coupling will be non-mechanical, but virtual and will be maintained by means of distance control technology. A special challenge of the virtual coupling in railway operation is the peril point of the switch in case of failure during the passage of two trains which are coming from different tracks, running in close succession at high-speed. Therefore some concepts are unrealizable with the current switch technology. Nevertheless there are situations where virtual coupling seems promising. One scenario is the virtual coupling at low speed, e.g. in the proximity of a station, where a safe brake is possible in case of a switch failure. The “Shinkansen” scenario aims to increase line capacity on the Tokaido high-speed line in Japan between Tokio and Osaka. The fastest “Nozomi” trains are stopping only at major stations. These stations have two tracks per direction with a 400 m platform. The idea is to double the number of Nozomi trains. So in every stopping station, there are two trains arriving and departing in a short interval. The distance on the open line is not that close, so it is more a ride within relative braking distance than a virtual coupling. To evaluate that scenario a special railway operation simulation has been developed, which is able to handle virtual coupling. The simulation shows the possibility to increase seating capacity from 15,000 to 23,000 seats per hour and direction. One bottleneck is occurring in Nagoya, where an additional platform is needed. Also the return time in Tokio has to be shortened to no more than 15 minutes.

Abstract: A split-level seating device for elevating and mounting alternate rows of seats for aircraft, surface transportation or for stationary applications, as a means to gain greater seating comfort and to increase overall seating capacity, by pre-empting otherwise unutilized or inefficient spatial displacement within such vehicles, to enable every sitter a lower seating position and every sitter to raise the legs at or above the level of the torso A modular pedestal raises every other row of seats with their corresponding cross-aisle walkways at a sufficient height to provide legroom for floor level sitter, said module incorporating a legrest extension for upper level sitter, including the means for affixing state-of-the-art safety, sanitary and conveniency devices, such as safety crash-absorbing air bags and high-security kevlar lining, oxygen dispensers, purge vents and ultra-violet light outlets to cleanse the environment, moveable and adjustable footrests, eating-writing surfaces, and audio-visual entertainment and communications devices The manner following convention of mounting arrays of massed seats at floor level is improved upon by elevating alternate rows of seats by means of said modular devices, all seats, both floor and split-level, being accessed from the same floor surface
