【摘要】：航班计划作为航空公司组织生产的依据，是航空公司经营规划的核心，合理的航班计划可以有效的保障飞行安全，提高航空器的利用率，最终提高航空公司的经济效益。地理信息系统是分析和处理空间数据的一门应用工程技术，近几年已经在各大领域有所发展，用地理信息系统来分析和编辑航班计划，可以有效的提高航班计划编排的准确性，但是地理信息系统涉及到大量地理数据，系统在处理数据和地图显示方面面临较大挑战，因此，提高数据的查询效率，保证系统能够快速响应用户的需求是本系统设计的最终目的。本文一共分为五章，重点对ForGIS中的多任务调度问题进行研究。首先，在设计过程中引入“协同”的概念，在协同设计思想的指导下，合理的进行任务分配和任务调度；其次，本文采用多Agent技术建立系统总体模型，以合同网为基础建立任务调度模型，并在模型中提出了基于黑板和消息传递的混合通信技术，建立空间数据库；最后利用Delphi语言实现了本系统，在一定程度上达到了系统设计的目标，对系统的性能进行评价。
[Abstract]:As the basis of airline organization and production, flight planning is the core of airline business planning. Reasonable flight planning can effectively ensure flight safety, improve aircraft utilization rate, and ultimately improve the economic benefits of airlines.Geographic Information system (GIS) is an applied engineering technology for analyzing and processing spatial data. In recent years, it has been developed in various fields. Using GIS to analyze and edit flight plans can effectively improve the accuracy of flight planning.However, GIS involves a large number of geographic data, and the system faces great challenges in data processing and map display. Therefore, the efficiency of data query is improved.To ensure that the system can quickly respond to the needs of users is the final purpose of the system design.This paper is divided into five chapters, focusing on the study of multitask scheduling in ForGIS.Firstly, the concept of "collaboration" is introduced into the design process, and the task assignment and task scheduling are reasonably carried out under the guidance of collaborative design. Secondly, the system model is established by using multi-#en0# technology.The task scheduling model is established on the basis of contract net, and the hybrid communication technology based on blackboard and message passing is put forward in the model, and the spatial database is established. Finally, the system is realized by using Delphi language.To a certain extent, the goal of system design is achieved, and the performance of the system is evaluated.
