【摘要】:航班計劃作為航空公司組織生產(chǎn)的依據(jù),是航空公司經(jīng)營規(guī)劃的核心,合理的航班計劃可以有效的保障飛行安全,提高航空器的利用率,最終提高航空公司的經(jīng)濟(jì)效益。地理信息系統(tǒng)是分析和處理空間數(shù)據(jù)的一門應(yīng)用工程技術(shù),近幾年已經(jīng)在各大領(lǐng)域有所發(fā)展,用地理信息系統(tǒng)來分析和編輯航班計劃,可以有效的提高航班計劃編排的準(zhǔn)確性,但是地理信息系統(tǒng)涉及到大量地理數(shù)據(jù),系統(tǒng)在處理數(shù)據(jù)和地圖顯示方面面臨較大挑戰(zhàn),因此,提高數(shù)據(jù)的查詢效率,保證系統(tǒng)能夠快速響應(yīng)用戶的需求是本系統(tǒng)設(shè)計的最終目的。 本文一共分為五章,重點對ForGIS中的多任務(wù)調(diào)度問題進(jìn)行研究。首先,在設(shè)計過程中引入“協(xié)同”的概念,在協(xié)同設(shè)計思想的指導(dǎo)下,合理的進(jìn)行任務(wù)分配和任務(wù)調(diào)度;其次,本文采用多Agent技術(shù)建立系統(tǒng)總體模型,以合同網(wǎng)為基礎(chǔ)建立任務(wù)調(diào)度模型,并在模型中提出了基于黑板和消息傳遞的混合通信技術(shù),建立空間數(shù)據(jù)庫;最后利用Delphi語言實現(xiàn)了本系統(tǒng),在一定程度上達(dá)到了系統(tǒng)設(shè)計的目標(biāo),對系統(tǒng)的性能進(jìn)行評價。
[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.
