The function-to-form mapping of left alternative is. It is supposed that there are two alternatives to be selected. There are 7 different subsystems for architecting, and every subsystem can execute certain function. The concept of system architecture can be illustrated as in Figure 1. The allocation of physical or informational elements of function into elements of form is one of the earliest and most important architectural decisions that have to be made. ” This precise definition can be expressed briefly as function-to-form mapping where the function executed by the different subsystems and the form is the relationship among them. More formally, Crawley defines architecture as “an abstract description of the entities of a system and the relationships between those entities.” However, a more precise definition is given by Crawley in MIT Engineering Systems Division as follows: “the embodiment of a concept: the allocation of physical/informational function to elements of form, and the definition of interfaces among the elements and with the surrounding context. The first researcher to formalize the concept of “systems architecting” is Rechtin, and his book with Maier is the best introduction to this field. Driven by the tasks to be conducted in given mission, the UAVs system architecture model can be treated as a solution of corresponding task assignment problem. In this paper, we focus on the modeling and optimization of multiple UAVs system architecture to maximize mission performance. Also, some problems related to multiplatforms (UAVs included) collaborative disasters monitoring have conducted by BAI GuoQing. Studies on UAVs for disaster monitoring have been conducted by several researchers.

The effectiveness of disaster response depends on the coordination of these tasks. Huge difference exists between different tasks in the degree of urgency and difficulty. Disaster response consists of various types of tasks, that is, warning/evacuation, search and rescue, providing immediate assistance, assessing damage, continuing assistance, and the immediate restoration of infrastructure. Disaster relief and emergency response missions could be a fifth category in the civil uses of UAVs systems they are expected to be “force multipliers” in disaster response just as in achieving military missions.

UAV systems have potential to augment the effectiveness of disaster response dramatically based on their excellent performance in dull, dirty, or dangerous environment.

Here, the disaster management supported by UAVs is taken for demonstrating. They can operate in areas where it would be irresponsible to expect pilots to fly, for example, low level, night flights over the Arctic Ocean, flights over regions where there is low level strife. UAV systems come in all sizes, and although most are for military applications, they have already been used in civilian activities. Unmanned aerial vehicle (UAV) systems, which were developed for military purpose originally, are currently in limited use for public service missions worldwide.

The availability and effectiveness of overall method is validated using 2 simulations based on 2 different scenarios. Then the corresponding optimization problem and an efficient genetic algorithm with a refined crossover operator (GA-RX) is proposed to accomplish the architecting process iteratively in the rest of this paper. Based on the general system architecture problem, a specific description of the multi UAVs system architecture problem is presented. This can be extracted as a multi UAVs system architecture problem. Confronted different types of tasks, multi UAVs usually need to be coordinated. Unmanned aerial vehicle (UAV) systems have already been used in civilian activities, although very limitedly.
