Wherein, the first 8 bits represent the observation sequence of the loopholes, which is: loophole 2, loophole 4, loophole 3, loophole 1, loophole 2, loophole 3 and loophole 4; bits 9 to 16 represent the satellite order in which the observations were performed, in order: satellite 2-satellite 1-satellite 3-satellite 2-satellite 1-satellite 3.

By way of example, the vulnerability maintenance sequence obtained in step S120 is used to repair the vulnerability of the commercial satellite operation control platform, so that the vulnerability that affects the operation of the commercial satellite is preferentially processed, thereby ensuring the stable and safe operation of the commercial satellite operation control platform.
In summary, the vulnerability processing method for the commercial satellite operation control platform provided by the embodiment of the application constructs the double-layer code by the satellite identification information and the vulnerability identification information in the vulnerability information, calculates the vulnerability maintenance sequence by the double-layer code through the genetic algorithm, and can intelligently sort the vulnerability maintenance sequence based on the type of the vulnerability and the two dimensions of the satellite in which the vulnerability occurs, so that the vulnerability which affects the operation of the commercial satellite is preferentially processed, and the stable and safe operation of the commercial satellite operation control platform is ensured.
In some examples, the obtaining the vulnerability maintenance sequence by using the genetic algorithm of the vulnerability information based on double-layer coding includes:
constructing a double-layer code according to the satellite identification information and the corresponding vulnerability identification information;
and executing the fitness allocation operation, the first selection operation, the cross operation, the mutation repair operation and the second selection operation based on the double-layer code to acquire the vulnerability maintenance sequence.
For example, the genetic algorithm for obtaining the vulnerability maintenance sequence based on the double-layer code by using the vulnerability information may be implemented in the manner of fig. 2, firstly, constructing the double-layer code according to the satellite identification information and the vulnerability identification information corresponding to the satellite identification information, then sequentially performing fitness allocation operation, first selection operation, cross operation, mutation repair operation, and second selection operation, performing convergence judgment after the second selection operation, and if the convergence judgment is not performed after the second selection operation, continuously and circularly performing the fitness allocation operation, the first selection operation, the cross operation, the mutation repair operation, and the second selection operation after the convergence judgment parameter is changed, so that the adaptability allocation operation, the first selection operation, the cross operation, the mutation repair operation, and the second selection operation are satisfied, and outputting the vulnerability maintenance sequence.
In some examples, performing the fitness allocation operation, the first selection operation, the cross operation, the mutation repair operation, and the second elite retention operation to obtain the vulnerability maintenance order based on the double layer encoding includes:
performing fitness allocation operation on the double-layer code to obtain a fitness code;
performing a first selection operation on the fitness codes by adopting a first elite retention strategy to obtain a first target offspring population;
performing cross operation on the first target offspring population to obtain cross codes;
performing mutation repair operation on the cross codes to obtain mutation codes;
performing a second selection operation on the variant codes by adopting a second elite retention strategy to obtain a second target offspring population;
continuing to execute the fitness allocation operation, the first selection operation, the crossover operation, the mutation repair operation and the second elite retention operation for a preset number of times on the second target offspring population, wherein the preset number of times is determined based on the number of the children in the second target offspring population;
outputting all the sub-volumes reserved by the first selection operation and the second selection operation according to the reservation sequence to obtain the vulnerability maintenance sequence.
Illustratively, the fitness assignment operation is first performed by a fitness function, and the ratio of the subtasks to the number of all subtasks is arranged to obtain the fitness code. And coding the fitness, and selecting a offspring population by a selection operator through an elite retention strategy so as to obtain a first target offspring population. The individuals with the highest fitness in the first target offspring population are directly reserved in the next generation population, and do not participate in operations such as crossing, mutation and the like. It should be noted that, the elite retention is adopted in the genetic algorithm in the evolution process, the present optimal individual cannot be lost and destroyed by the selection, crossing and mutation operations, and the elite retention strategy can effectively improve the global convergence capability of the algorithm. Performing a memorial crossover operation on the first target offspring population: the crossover operator is in front of the individual
The bits generate crossing points and perform a crossing operation on the first target offspring population. Because of a certain relation between the sequence numbers of the satellite coding layer and the sequence numbers of the measurement and control station coding layer in the multi-layer coding process, illegal solution can be caused after the measurement and control activity sequence is exchanged immediately, namely, certain satellite measurement and control times are redundant, and other task measurement and control times are missing. Therefore, it is necessary to change redundant observing and controlling activities into missing observing and controlling activities and adjust the +.>

And selecting two gene sites, exchanging resource genes, checking the legitimacy of the chromosome genes, and repairing illegal individuals to obtain variant codes. And performing a second selection operation on the variant codes by using a second elite retention strategy to obtain a second target offspring population. And continuously executing the adaptability allocation operation, the first selection operation, the crossover operation, the mutation repair operation and the second elite retention operation for the second target offspring population for a preset number of times to meet convergence, and outputting a vulnerability maintenance sequence after convergence. It should be noted that, the preset number of times is determined based on the number of the children in the second target child population, and when there is no child in the second target child population, the algorithm convergence state is corresponding.
In summary, according to the commercial satellite operation platform vulnerability processing method provided by the embodiment of the application, elite is reserved in the genetic algorithm in the evolution process, the optimal individuals are not lost and destroyed by selection, crossing and mutation operations, the global convergence capacity of the algorithm can be effectively improved, meanwhile, the cross operation on codes can effectively solve redundancy of certain satellite measurement and control times, and accordingly the maintenance sequence of the output vulnerability can be rapidly calculated.
In some examples, the above fitness allocation operation is implemented based on a Griewank function.
Illustratively, the Griwang function (Griewank), there are local minima, the number is related to the dimension of the problem, and the minimum is taken at (0, 0 … 0). A nonlinear multi-modal function, has a very wide search space, and can be used for the fitness allocation operation of genetic algorithms. The Griewank function is a typical multimode test function consisting of a quadratic convex function and an oscillation non-convex function, and the Griewank function has the phenomenon that the optimization difficulty is firstly difficult and then easy in the optimization process along with the increase of the dimension of the function, and the input of the Griewank function is double-layer coding and cannot influence in the convergence aspect.
In some examples, the above method further comprises:
acquiring the number of new loopholes under the condition that the number of the sub-bodies of the second target sub-population is smaller than the preset observed number, wherein the new loopholes are loopholes generated after the genetic algorithm is executed;
generating a nascent bilayer code based on the nascent vulnerability and the second target offspring population if the nascent vulnerability number is less than a minimum optimized number;
and acquiring a new vulnerability maintenance sequence according to the genetic algorithm based on the double-layer coding.
In an exemplary embodiment, the method inputs the vulnerability codes in a period of time into a genetic algorithm model, and calculates all the coded vulnerabilities in the period of time through the genetic algorithm and outputs a vulnerability repair sequence, where the number of the second target offspring population is too small, the importance of the newly generated vulnerability may be higher than the importance of the remaining children of the second target offspring population, but the vulnerability is repaired before the new vulnerability. Therefore, when the number of the children of the second target offspring population is smaller than the preset observed number, the new-born vulnerability number is obtained, and when the new-born vulnerability number is smaller than the minimum optimized number, the determined vulnerability restoration sequence is output, and restoration is carried out according to the vulnerability restoration sequence. And generating a new-born double-layer code by using the new-born holes and the residual daughter in the second target offspring population, and acquiring a new-born hole maintenance sequence based on a genetic algorithm of the double-layer code, so that the residual daughter and the new-born holes can be used as a whole to perform hole repair sequence optimization, and the obtained repair sequence is more reasonable.
In some examples, the above method further comprises:
acquiring the acquisition time of the sub-body of the second target sub-population;
and stopping generating the new double-layer coding operation under the condition that the acquisition time of any child is longer than the preset time, and continuously acquiring the vulnerability maintenance sequence based on the genetic algorithm of double-layer coding according to the second target child population.
In the process of optimizing the bug repair sequence by taking the residual subvolumes and the new-born bugs as a whole, the acquisition time of some subvolumes is longer than the preset time, namely the time for acquiring the bugs is long, if the residual subvolumes and the new-born bugs are continuously adopted as a whole to optimize the bug repair sequence, the repair of some subvolumes still cannot be completed within a long time due to the fact that the repair grades of some subvolumes are lower, the new-born double-layer coding operation is stopped, the bug maintenance sequence is continuously acquired based on the genetic algorithm of the double-layer coding according to the second target offspring population, and therefore the bugs with longer occurrence time and lower bug grades can be effectively repaired in time.
In some examples, the above method further comprises:
acquiring the current vulnerability information quantity being processed and the vulnerability information quantity to be processed;
under the condition that the information quantity of the in-process loopholes is larger than a first preset threshold value and/or the information quantity of the to-be-processed loopholes is larger than a second preset threshold value, acquiring a loopholes maintenance sequence based on a genetic algorithm of double-layer coding, and repairing loopholes of the commercial satellite operation and control platform according to the loopholes maintenance sequence; or alternatively, the first and second heat exchangers may be,
and performing vulnerability repair according to the vulnerability acquisition time sequence under the condition that the vulnerability information amount being processed is smaller than or equal to a first preset threshold value and the vulnerability information to be processed is smaller than or equal to a second preset threshold value.
For example, in order to save calculation power, the amount of vulnerability information being processed and the amount of vulnerability information to be processed are counted, and if the amount of vulnerability information being processed is greater than a first preset threshold value and/or the amount of vulnerability information to be processed is greater than a second preset threshold value, then the accumulated vulnerabilities are considered to be more, and a genetic algorithm is required to perform optimization arrangement on the repair sequence. If the information amount of the loopholes being processed is smaller than or equal to a first preset threshold value and the information amount of the loopholes to be processed is smaller than or equal to a second preset threshold value, the number of the loopholes is considered to be smaller at the moment, calculation optimization can be performed without adopting a genetic algorithm, and the loopholes are repaired according to the acquisition time sequence of the loopholes.
