A method for planning a transportation service includes sending transportation proposal to a plurality of organizations. The proposal includes one or more initial options, each including a set of variable parameters. Each organization can generate a modified option and make a commitment conditional on selected ones of the parameters. Each organization sends respective modified options to commuters of that organization who may specify their own pledges for at least one of the modified options, conditional on the organization-selected values for the variable parameters and optionally on commuter-selected values for the variable parameters. A cost-benefit function is computed for each of a set of revised options for the transportation service, each of the revised options being based on a combination of the variable parameters for which pledges which cover the combination have been received and one or more of the revised options is identified, based on the computed cost-benefit function.

The invention relates to an intelligent control method based on adaptive planning of a virtual ship for an under-drive unmanned ship formation. The method comprises the following steps of 1, setting aformation and initializing parameters; 2, collecting a position coordinate (xL, yL) and a heading angle psiL of a leader ship, conducting wave filtering, and transmitting the position coordinate andthe heading angle to a following ship; 3, according to the formation, the position coordinate and the heading angle information of the leader ship, obtaining a reference position (xr, yr) and a reference motion posture psir of the following ship in the formation in real time; 4, introducing the virtual ship and conducting real-time adaptive planning to obtain a reference track of the following ship; 5, using a combination strategy of RBF neural networks and a minimum parameter learning algorithm to train learning parameters online to generate intelligent formation control signals, wherein theintelligent formation control signals include the rotating speed nF of a mainframe of the following ship and a rudder angle command signal deltaF. Compared with the prior art, the method has the advantages that the method adapts to curved path tasks, overhead is avoided, leader ship speed information is not needed, and the method is simple, convenient and excellent in real-time performance.

The invention discloses a self-adaptive planning method for an atmosphere entrance guidance trajectory. The method comprises the following steps: (1) acquiring a change rule of a flight longitudinal range and a cross range along with a heeling angle; (2) sectioning a whole entrance process, and determining a guidance law of each stage; (3) setting different entrance point initial longitudinal ranges, judging whether parachute-opening states in different entrance points satisfy given constraints, if so, positively increasing the initial longitudinal range or negatively decreasing the initial cross range, until a certain constraint is not satisfied, and determining a limit range of the initial longitudinal range which can be adjusted by the above guidance law; (4) in a actual flight process,judging whether the initial entrance point longitudinal range is within the above limit range, if so, using the guidance law in the step (2) to control; if not, executing the step (5); and (5) calculating a deviation value of the actual initial longitudinal range exceeding the limit range, correcting a longitudinal range reference value of a reference ground track, and substituting a corrected value into the guidance law in the step (2), to obtain a new guidance law, and using the new guidance law to control.
