  1. A modified genetic algorithm ( mga ) framework was developed and applied to the flowshop sequencing problems with objective of minimizing mean total flowtime. to improve the general genetic algorithm routine, two operations were introduced into the framework. firstly, the worst points were filtered off in each generation and replaced with the best individuals found in previous generations ; secondly, the most promising individual was selectively cultivating if a certain number of recent generations have not been improved yet. under conditions of flowshop machine, the initial population generation and crossover function can also be improved when the mga framework is implemented. computational experiments with random samples show that the mga is superior to general genetic algorithm in performance and comparable to special - purpose heuristic algorithms. the mga framework can also be easily extended to other optimizations even though it will be implemented differently in detail

    提出了一個改進遺傳演算法的結構,並且應用於帶有目標是最小平均總流程時間的流水調度排序中.為了改進一般遺傳演算法的程序,兩個新的操作被引進到這個操作中.這兩個操作為: 1 )過濾操作:過濾掉在每一代中的最壞的個體,用前一代中的最好的個體替代它; 2 )培育操作:當在一定代數內演算法不改進時,選擇一個培育操作用於培育最有希望的個體.通過大量的隨機產生的問題的例子的計算機實驗顯示出,提出的演算法的性能明顯好於一般遺傳演算法,並且和此問題的最好的專門意義的啟發式演算法相匹配.新的mga框架很容易擴展到其它最優化當中,只是實施的詳細的步驟有所不同
  2. Examine the warm triangular awl composition and adopt mineral raw materials to compound, its physics performance and ceramic glaze medicine are self - same, utilize fire - resistant degree of it as melt temperature of pouring, in cooking, set according to the operation instructions free in examined warmly position in products, can examine to the actual temperature of the products ( can be observed with the naked eye ), especially push away and pull the kiln, tunnel kiln, drawer kiln observe temperature must spend products, general difference in temperature 5 - 10 degrees centigrade, please and soften some forms of contrasting according to the operation instructions, serial number before using

    測溫三角錐成分採用礦物原料配製的,它的物理性能與陶瓷釉藥完全相同,利用它的耐火度作為熔倒溫度,在產品燒成中,按使用說明放在所測溫的位置,可測到產品的實際溫度(用肉眼可觀察到) ,尤其是推扳窯、隧道窯,抽屜窯內觀察溫度必用產品,一般溫差5 10 ,使用前請按使用說明、編號及軟化點對照表。
  3. On the other hand, an improved routecrossover operator ( rc " ) is introduced. with the increasing size of a problem, it can obtain general optimality of four indexes on the premise of satisfying every customer ' s demand : distance, vehicle number, idle time and no - service number, and its performance is superior to pmx and rc

    第二,採用改進的路徑交叉運算元』 ,它不僅可以滿足所有需求點的要求,而且隨著問題規檬的增大,它在取得運行距離、車輛數目、閑置時間和未得到服務的送貨點數四項指標的綜合最憂方面明顯憂于pmx及rc運算元。
  4. Abstract : a method named multi - times optimization is presented to solve the multi - specification optimization problem, which is difficult to solve using the variational optimal theory. in the method several demands are reduced to some sub - tasks. in every subtask a demand that can not be transformed into bound condition is taken as performance specification for optimazation, and the other demands are taken as bound conditions. by means of the method, the arrival time, number of turn, turn angle of the aircraft in the terminal area are selected as performance specification separately, and the general character of optimal flight route in the terminal area is given

    文摘:為了給飛機提供一條能滿足多種指標要求的最優飛行軌跡,針對變分最優理論難以求解多指標優化問題,提出了命名為多次優化的方法,即將多要求的優化任務分成先後相繼的多次任務,每次任務中選取一種不能邊界轉化的要求作為最優性能指標,而其餘要求轉化為邊界條件.利用這一方法以時間、轉彎次數、轉彎角度為最優性能指標給出了終端區最優飛行軌跡的一般特徵
  5. Using matlab, the step response characteristics of the valve in the elevator system is simulated, comparing the effect of its performance with different structure parameters of the pipe rupture valve, such as hydraulic resistance, diameter of the valve, and spring rigidity, and comparing the valve ' s dynamic performance under different operating conditions, such as environment temperatures, number of passengers, and emergencies of the hydraulic system, so the paper offers a general and systematic analysis for the pipe rupture valve of the elevator system

    另外,在液壓電梯不同的工況下,對該閥的動態性能進行了模擬對比研究,如不同環境溫度、不同乘客人數、不同液壓系統意外,以及不同的油液體積彈性模量,比較全面系統的分析了限速切斷閥在電梯系統中的性能,根據這些模擬結果,可以分析該閥正常工作的工況要求和環境要求。
