Abstract

The project presents a methodology for choosing the optimal architecture using, as an example, global navigation satellite system, namely its space segment. Several architectures of the GLONASS system were taken as an example for testing the methodology. The usage of traditional methods of multi-criteria analysis in this case is too way difficult due to the presence of a large number of particular navigation tasks, that often put forward contradictory and uncertain requirements for their resolution, the presence of a large number of private criteria, the need to involve a large number of decision makers (DM), and as a consequence, a conflict of interests, difficulty in setting weights, determining preferences, etc. The confident judgment method was used to implement the task. The system of private criteria was structured, taking into account the requirements of specific narrow segments, and their preferences were formed. After that, tables were built for each structure, according to the required number of criteria and for three different particular tasks, as well as to normalize and collapse the criteria for each task into one criterion. Then a set of Pareto-rational solutions and a rating of alternatives were formed. The final appearance of the system satisfied the requirements imposed by the consumer segment. Keyword

使用多准则分析方法选择GLONASS空间段最佳结构的方法
该项目提出了一种选择最佳结构的方法,以全球导航卫星系统(即其空间段)为例。以GLONASS系统的几种结构为例,对该方法进行了验证。在这种情况下,使用传统的多标准分析方法是非常困难的,因为存在大量特定的导航任务,这些任务往往对其解决提出矛盾和不确定的要求,存在大量的私人标准,需要涉及大量的决策者(DM),因此存在利益冲突,难以设置权重,确定偏好等。采用自信判断方法实现该任务。考虑到特定窄段的要求,构建了私人标准系统,并形成了他们的偏好。之后,根据所需的标准数量和三个不同的特定任务,为每个结构构建表,并将每个任务的标准规范化并合并为一个标准。然后形成了一组帕累托理性解和一个备选方案评级。该系统的最终外观满足了消费者部分的要求。关键字
