Secondly the paper describes mathematically the steady index for container terminals based on the theory of queue networks and then deals with the events of the queue models of vessel arriving and leaving in this disperse system using the event scheduling method
其次,論文以排隊網路理論,對集裝箱碼頭的一些穩態指標作了數學描述,最後利用事件調度法對集裝箱碼頭這一離散系統的船舶到、離港的排隊模型進行事件處理。Although there have been many application instances in the field of input / output device technology, we need an specific project and technology route aimed at an given application. in this thesis, we combine the introduction and analysis of relative technology to describe the accomplishment of a coordinate collecting device which is based on incremental rotary encoder. this device is an specific device applied to collect the corrdinate displacement of ground image ’ s three - dimensional model created by full digital photogrammetric station. cpld chip and vhdl are applied in this device to carry out the following work : phase control of the electrical pulse created by incremental rotary encoder, counting the number of electrical pulse, controling the state of signal processing circuit, exchanging data between this circuit and pci control
本文結合相關技術的介紹和分析,描述了一個基於增量式旋轉編碼器的坐標參量採集介面卡的實現,此介面卡是一種用於採集全數字攝影測量系統地面影像模型坐標位移量的專用設備,該設備採用cpld器件和vhdl語言實現增量式旋轉編碼器的脈沖信號鑒相和計數、信號處理部分的狀態控制以及和pci總線晶元ch365之間的數據交換和通信功能,同時該設備的驅動程序基於wdm模式,並且配置有結構良好的動態鏈接庫程序作為系統軟體和驅動程序之間的數據和控制交互中間介面,能夠方便地運行在windows98 / 2000 / xp操作系統平臺上,具有實時性強、工作穩定、通用性較好和性價比高等特點。The target is that it begins with the information of the graph ( based on pdm ) used to directly depict parts, being supported by the currency cad / cam system, receiving the producing information by interact with manual, matching the cutter with expert system, building the data of the cutter location ( cl ) by account, finishing the optimising arrangement, creating the nc program for the numerical control system of the fms - ii of sheet metal by the post system, automatically processing the produce by the nc machine tool according to the cl, and then realizing the opening integration of the system of cad / cam system of the fms - ii for sheet metal, basing on pdm
為了解決這些問題,需要重新開發fms -的cad cam系統,目標就是從基於pdm下的通用cad系統提供的圖形信息直接描述零件開始,人工交互方式輸入加工信息,由專家系統的推理機實現自動配模,經計算產生刀位文件,優化排料后,再針對鈑金fms -的數控系統,後置處理生成相應的數控加工程序,數控機床根據加工程序代碼自動完成加工,從而實現鈑金fms -的cad cam系統基於pdm下的開放集成。The most important such information is a small set of character stringsdescribing attributes of the object being requested, including its uri, filename, content - type and content - encoding ( these being filled in bythe translation and type - check handlers which handle the request, respectively )
這些信息中最重要的是一個小的字元串的集合,他們描述了被請求對象的屬性,包括它的uri ,文件名,內容類型和內容編碼(它們在處理請求時,被分別填入翻譯和類型檢查句柄) 。This thesis is focused on the following flve topics. first, comparative analysis of binary encoding and float encoding is made, the advantage and disadvantages of two encoding modes and their influence on genetic operators are clarified, thus the basis for reasonable description of the problems is provided. secondly, as genetic operators have an important influence on performance of algorithms, this thesis demonstrates that the simulated binary crossover can keep the mean of population unchanged, and under some conditions
作者在論文期間的工作主要集中在以下幾個方面:對遺傳演算法中的二進制編碼和浮點數編碼進行對比分析,闡明兩種編碼方法的優缺點和對遺傳操作運算元的影響,為合理地描述待解決的問題提供一定的依據;遺傳操作運算元對演算法的性能有重大的影響,文中對模擬二進制交叉運算元對群體的分佈影響進行了分析論證,得出模擬二進制交叉能保持群體的均值,並在滿足一定條件下使群體方差變大的結論;如何保持群體的多樣性,一直是進化演算法研究的主要內容。分享友人
