B, formation initial scheme: form a plurality of selectable initial scheme, three conditions that direct train is started by selecting to satisfy the condition of starting direct train:
Necessary condition: independent or many long-range wagon flows of any long-range wagon flow merge starts the direct train arrival station, its necessary condition be on the way technical station do not have that reorganization hour saves by the car that obtains must be more than or equal to of the assembly car hour consumption of this direct train arrival station, that is: at the starting station
N
Directly∑ t
Joint〉=cm;
Wherein: N
Directly---the through train flow;
t
Joint---through wagon flow does not have the car of reorganization by technical station on the way and hour saves time;
The assembly parameter of c---technical station;
M---train weave into a number.
With six technical stations of rectilinear direction is that example describes, and technical station A starts and arrives the wagon flow of technical station D, if tissue is through, it hour consumes and must not have saving time of station B that reorganization passes through and C halfway less than it at the assembly car at A station so.Suppose that it hour consumes at the assembly car at A station is 600, saving in the nothing reorganization at B station is 360, and saving in the nothing reorganization at C station is 380, and wagon flow AD just meets and starts through necessary condition so.
Adequate condition: the long-range wagon flow of single or many merging, adequate condition to shorter direct train arrival station or short through wagon flow, be that its nothing reorganization in the acquisition of overtaking section is passed through the car hour saving of technical station more than or equal to the car of assembling at the starting station hour consumption, that is:
t
Joint is far away---long-range wagon flow does not have reorganization at the section that is out of the line and saves by the time of technical station acquisition on the way.
With six technical stations of rectilinear direction is that example describes, it is through to suppose that wagon flow AE, AF start, assembling car hour consumption all is 600, wagon flow AF does not have the saving of reorganization by E station, and to be 640,640〉600 direct train AF satisfy adequate condition to direct train AE promptly requires wagon flow AF not have car that reorganization passes through at the E station hour to save greater than it and hour consume at the assembly car of technical station A.
Absolute condition: any single Zhi Yuancheng wagon flow is started the absolute condition of direct train separately, and to be it in the nothing reorganization of arbitrary technical station on the way hour save all more than or equal to the assembly car at this direct train arrival station by car hour consumes, promptly;
t
Joint is minimum---single Zhi Yuancheng wagon flow does not have reorganization and saves time by the minimum in the technical station on the way.
Example with the explanation necessary condition is analyzed, if wagon flow AD hour saves greater than hour consuming 600 at the assembly car at A station at the car at its technical station B that passes through and C station, then wagon flow AD satisfies the absolute condition of starting direct train.
C, project setting: change the operation situation of wagon flow, satisfy the wagon flow of three kinds of conditions and represent with three kinds of different forms with the wagon flow that does not satisfy any one condition by the relevant art station; Satisfy the wagon flow of absolute condition and represent, satisfy the wagon flow of relative conditon and represent, do not start through wagon flow and represent with black with green with redness.Changing wagon flow is to represent wagon flow to realize in the color of the numeral of the car hour consumption at this station to change in the operation situation of technical station, just can change the operation situation that color digital on the button has also promptly changed this station as long as click the corresponding button in station.
D, formation final plan: adjust the back and form final plan, listed the reorganization scheme of wagon flow and the reorganization operation situation of each technical station automatically,, proceed to adjust if be unsatisfied with;
