After generalizing the characteristic of modern equipment, the mission of equipment management and general situation of chinese equipment management, basied on two forms of equipment management - - - - - - practicality & value, the author combined quantitative & qualitative methods with example to analyze and discuss questions, especially the reasonable update & depreciation, accordingly achieving the optimization of the technical efficiency & economic benefit 0 one of emphases of the thesis is methods application of equipment reasonable update, that is starting with economic benefit to looking for reasonable using fixed number of year. the thesis used inferior - converted numeric method and rate equation which based on the theory square and combined with harbor loading machines & tugboat ' s actual facts, calculated the economic life of the same machine in order to make sure harbor machines " reasonable using fixed number of year. at the same time, the author made use of midpoint value regress method and stochastic trapeziform forecast method to calculate and analyze and gain the reasonable conclusion o the other emphases is questions of harbor equipment
本文概括介紹了現代設備的特點、設備管理的任務以及我國設備管理發展的概況后，作者從設備經濟管理的兩種形態? ?實物形態和價值形態出發，採取定量與定性相結合，以定量為主，結合實例進行分析與論述，對港口設備的合理更新與折舊問題進行了著重研究，從而實現設備的技術效能和經濟效益的最優化。本文研究的重點之一是設備合理更新的方法應用，即從經濟效益出發，來尋求設備的合理使用年限。本文結合港口裝卸機械和港作拖輪的實際，運用以正方形理論為基礎的低劣化數值法和費用方程兩種方法，計算了同一種機械設備的經濟壽命，從而確定港機合理的使用年限，同時，運用了中點值回歸法和隨機梯形預測法進行計算和分析，得到了合理的結論。This thesis suggests a process considered minimizes the population size as similar individuals occur in the fitter members of the population, which helps reduce the execution times for ga by removing the redundancy associated with the saturation effect found in the later generation. this thesis uses a method that adds dynamic penalty terms to the fitness function according to the optimal degree of solutions, so as to create a gradient toward a feasible suboptimal or even optimal solutions. on the basis of the difference of the biggest and the smallest of fitness of individual, modifying the fitness function in order to convergence is a satisfaction
動態調節種群大小，去掉遺傳演算法在迭代後期搜索產生的過多相似個體，達到減少計算時間的目的；按照解的優劣程度給適應度函數增加一個在ga搜索過程中動態改變的可變罰函數，給搜索最優解創造一個梯度，使遺傳演算法收斂到可行的較優解或最優解；根據適應度值最大和最小個體的差修正適應度函數，使適應度函數值適中不容易造成收斂太快、局部收斂或根本不收斂而變成隨機搜索；為了避免「近親繁殖」採用競爭擇優的交叉操作；利用并行遺傳演算法的思想，提出一種自適應多子種群進化策略；提出人口汰新政策來解決類似甚至相同的個體的情況發生。This thesis contrasts and analyses the different calculation - method, and improves the genetic algorithm in the parameter inversion of the rock and soil engineering. the strategies are mainly in the following three aspects : 1, new searching way is compositely searching genetic algorithm which is made up of the acceleration method and genetic algorithm when it partially calculates in the later time ; 2, index function is inducted in gengetic operators, at the same time repeated select and double exchange pool are used ; 3, splicing crossover, which reserves some new evolution factions, improves authority function accaunting the capabilities and kinds
本文對優化演算法中不同求解方法進行對比分析，針對遺傳演算法在巖土工程參數反演運算中進行了改進，改進的策略主要集中於三個方面： 1 、提出了在遺傳演算法中融入形加速法的改進方法? ?復合遺傳搜索法； 2 、針對遺傳運算元的選擇策略，引入指數適值方法，設置雙交換池，提出了重復篩選法； 3 、加強對劣勢種群的內部優良信息的遺傳功能的改進，引入權函數，擴大可交叉運算元的種類，保留各運算元的進化功能，提出了融合交叉運演算法。The writer analyzed mallat three criteria and introduced the optimized function based on these three criteria, at last found optimized mother wavelet for edge detection. at the end of this chapter single edge searching method based on local maximum is introduced and gained ideal edge image
分析mallat提出的評價邊緣檢測函數優劣的三個判別函數，利用這三個判別函數列出最優化方程，推導出邊緣檢測最優小波，最後創造性提出局部最大值單像素邊緣搜索法，提取出單像素寬度邊緣圖像，圖像效果達到了滿意的效果。分享友人
