By employing the development of the rvd simulation system as the research background, the main work of this dissertation is to study the docking dynamics of spacecraft with peripheral docking mechanisms and to develop the docking dynamics simulation system ( ddss )

本文以交會對接模擬系統研製為背景，研究了帶有周邊式對接機構的航天器對接動力學問題，並開發了對接動力學模擬系統（ ddss ） 。

4. simulation model for capture and buffer phase is built based on adams software, in the model, capture ring is accurately built with full consideration of actual geometrical feature, buffer system is modeled the same as that of ddss, and adams impact model

4 .建立了捕獲段與緩沖段的adams模擬模型，其中對接機構採用精確的實體三維模型，緩沖力模型同上，接觸力採用adams軟體提供的的impact模型。

The mechanism of the dsss to the users is like a black box and the users cannot distinguish the correctness of the results. the main reason is the insufficiency of users " interruption in the computer ' s operation and the blur mechanism of the ddss

整個過程對于用戶來說，計算過程是由計算機后臺程序進行黑箱操作的，用戶在運算過程中缺少必要的參與手段，也就是說透明交互性能不強，導致決策支持的效果不甚理想。

5. numerous simulations are done with different initial docking misalignment by adams software and ddss : ( 1 ) influence of the contact columbus friction to simulation results is inspected ; ( 2 ) adams results are compared with that of ddss, both the results validate each other ; ( 3 ) simulation results show good capture ability of

5 .對各種對接初始偏差，分別用adams與ddss進行了大量的模擬研究: （ 1 ）考察了接觸點處庫侖摩擦力對模擬結果的影響; （ 2 ） adams與ddss對比分析結果相互驗證了模型及演算法的正確性。

The key technology of mpidss includes the distributed supported technology, the process control of cooperative working and the real - time control of the decision process, etc. based on the technologies of decision support system ( dss ), group decision support system ( gdss ) and distributed decision support system ( ddss ), with the theory of system engineering and artificial intelligence such as knowledge engineering, agent, etc, having the background of the items supported by the national 10th five - year plan foundation - the research on the technology of military programming intelligent decision support system, this paper focus its work on researching on the algorithm of mission decomposing and mission distributing, distributed support technology, real - time process control method and project evaluating technology, etc. further more, the architectural model of process control based on multi - agent alliance is put forward and the prototype system of mpidss is implemented

這類決策問題與傳統的企業決策的不同點在於決策群體龐大、決策任務多且任務屬性各異、決策任務的求解具有實時性要求等。決策過程中的關鍵技術包括分散式支持技術、決策任務求解的過程式控制制技術以及實時任務的求解控制策略等。論文在繼承傳統的個體決策支持系統（ dss ） 、群體決策支持系統（ gdss ）和分散式決策支持系統（ ddss ）技術的基礎上，結合系統工程思想以及人工智慧中的知識工程、 agent等前沿技術，以總裝備部十五預研課題? ? 「群體決策支持平臺」為課題背景，深入研究了分散式多任務群體決策過程中的任務分解與分配演算法、任務協作策略、分散式支持技術、實時控制技術，決策方案評價技術等，提出了用於過程式控制制的多agent聯盟體系結構模型，設計和實現了面向軍事作戰規劃的智能決策支持原型系統。
