Foreword
In planning multiple waves missile launchers in (a) and network mapping data collation , we were edited out of the combat zone network diagrams, and time-consuming matrix of various models of traffic in the network. Next we come to study the issue of a problem-solving steps, which is the basis of several other asked, once the issue of problem-solving ideas and a model, ask a few other adjustments can be modified on this basis can easily get to.
problem analysis
Clear operational tasks Network Diagram
The multiple waves of missiles on combat missions established network charts, network diagrams equivalent to the map, is the fundamental basis of all combat missions scheduled. In planning multiple waves missile launchers in (a) and network mapping data collation , the preliminary finishing work has been completed. Here is to clear some of the information network diagram:
In a total network diagram 130 points, wherein
- Standby region D1 ~ D2 (Nos. 1 and 2)
- Reproduced region Z01 ~ Z06 (Nos. 3-8)
- Emitting region F01 ~ F60 (Nos. 9 to 68)
- Road node J01 ~ J62 (Nos. 69 to 130)
- J01 ~ J11 main road 1 (Nos. 69 to 79)
- J12 ~ J20 main road 2 (Nos. 80 to 88)
- J21 ~ J62 for other roads (numbered 89 to 130)
Clear combat mission launch vehicle attributes
In multiple waves missile launch tasks in this topic, perform the task of a total of three models, denoted A型车 B型车 C型车. These models and driving vehicles in accordance with the road, its running speed will be different:
| Quantity | Main road speed (km / h) | Other road speed (km / h) | |
|---|---|---|---|
| Model A | 6 | 70 | 45 |
| Model B | 6 | 60 | 35 |
| C car | 12 | 50 | 30 |
Clear strategy maneuvering combat missions
According topic related content description can be sorted out multiple waves Maneuvers missile launch combat missions:
Concealment in the standby region → projectile driving band to transmit a certain point (point can not be reused) → waiting → last car in place of the first wave volleys → → transfer area to driving arrangements loaded missile (not enough points, We will wait) → transmit traffic to a certain point (point can not be reused) → waiting → last vehicle position second wave volleys
Maneuvers can be more simply referred to as " DFZF ", i.e. in the standby region, the emitter region, the region between the reproduced walking.
Long exposure calculation clear combat mission
Refers to a long exposure time is subject to all vehicles from the standby region up to the sum of the second wave volleys completion time consuming task. among them
- In the standby region, because it is hidden standby, so there is no longer the exposure time.
- In the emission region, because you want to wait for all vehicles in place to volley, so the waiting time would count the region into long exposure.
- In the transfer area, a transfer area as a single loading operation mode, and the area can only accommodate two launch vehicle, so when there is three or more, the region exposed outside of the case will this time be calculated exposure duration.
- In all roads to calculate the average walking time consuming into long exposure.
D - Analysis and Solution F stage combat missions
Combat Task Analysis
First, the transmitting station 24 in a uniform distribution of vehicles carrying the missile concealment in the standby region. I.e. regions D1 and D2, respectively, each of the three arrangements for Model A, B three each car, C 6 units each car. After receiving the combat mission, launch vehicle the two regions started to move, after having left the waiting area, to find the nearest launch point to reach the launch point, place on standby. When the command (this is my imaginary) receive a final launch vehicle has reached the launch point of the message, issue a command to perform the first wave volley tasks, all missile launchers immediately. This is the first wave salvo.
Exposure time calculation
Long exposure calculation foregoing analysis can know, there must be a possibility that faster driving speed launch vehicle after reaching the specified emission points, will be on standby, waiting for the arrival of other local emission point, when there is a long exposure during this period.
As shown above on the left, in order to shorten the exposure time, the last salvo time must be short, that is, the last time a launch vehicle to reach shorter. However, if all vehicles on the same flight, although unlikely long crash (running fast in front of the slower runners in the back), and the first to express to wait for the slow, there is exposure to the emitting region. At this time, a total length equal to the last time is multiplied by the launch vehicle 24 reaches the exposure.
As shown above on the right, under the change of thinking is still the same car, the last time a car arrives too short. On this basis, so that the first express train in standby waiting area, then sent in succession, so that the exposure time was owned by the stand-in area, but the long exposure time is not included. Driving time-consuming equal length of all vehicles and the total exposure at this time. Long necessarily the shortest exposure time in this case. The question then converted to require that all cars to the shortest length of time spent problems and launch point.
Model building
According to the analysis, D - F stage combat missions can be classified as 任务指派问题. I.e., the emission point 60 is designated as a human, the transmitting station 24 as the task assigned car, a station transmits a car traveling from the standby to the traffic area takes emitting region as needed to complete a task someone the long time. 24 such that the objective function is the arrival time of the vehicle launchers desired emission point and the shortest (i.e., the shortest time required to complete tasks). among them
- Stage launch vehicle 24 need to follow the standby region and the models to calculate the length of time required to reach the emission point 60 (see below).
- Launch vehicle from the waiting area to the launch point of the time-consuming need to calculate the traffic, this has been (a) network mapping and data consolidation planning missile launch in multiple waves are received.
