In China, Mid-autumn Day is considered to be a symbol of family reunion. On this day, all the family members gather together at home to celebrate this special occasion. Last year, I could not celebrate the festival with my family because I was in university. However, this special day left a deep impression on me.
I still remember the atmosphere of that evening. All the students who could not go back home assembled in our classroom, having a party to celebrate this traditional festival. We tried our best to show our own enthusiasm. As an ethnic minority, I performed a peacock dance, which received warm applause. After the two-hour party, we went out to the playground and sat together to appreciate the moon because it is a tradition on Mid-autumn Day. We ate moon cakes, played cards, and listened to romantic poems recited by one of our classmates. In that harmonious atmosphere, nobody felt lonely or homesick even though we were far away from our homes.
Thanks to our classmates, I experienced such a colorful and interesting Mid-autumn Day at my university. Thus, I learned to value all the festivals I spent during my university life.

Because of the tendency to sit around a round table with family and friends, Mid Autumn Festival is also called 團(tuán)圓節(jié) (Roughly ‘Gathering Holiday’). And there is no denying that Mid Autumn festival is one of the most important traditional Chinese holidays.

關(guān)于描寫中秋節(jié)的英語(yǔ)作文
The Mid-Autumn Festival has all interesting history. Long ago in one of the dynasties of China there was a king who was very cruel to the people and did not manage the country well. The people were so angry that some brave ones suggested killing the king. So they wrote notes telling about the meeting place and time and put them into cakes. On the 15th day of the 8th lunar month every person was told to buy the cakes. When they ate them they discovered the notes. So they gathered together to make a sudden attack on the king. From then on the Chinese people celebrate on the 15th day of the 8th lunar month and eat "moon cakes" in memory of that important event.
When the Mid-Autumn Festival is near, shop windows are beautifully decorated. Many "moon cakes" are displayed for people to buy. People send presents such aswine, fruits and "moon cakes" to their friends and relatives. In the evening of the day, they have a feast. After the feast, they go out to the garden to look at the moon. The children run and laugh on the streets.
It is believed that the moon is at her brightest on this night. Many poems have been written about it, and poets are never tired of reading and writing such poems. In Chinese literature, the moon of the Mid Autumn Festival has been pared to a looking-glass, a jade rabbit, and so on. It seems that Chinese literature takes far more interest in the moon than in the sun.

Although the moon tonight "lazy", but kongmin light like the moon light the every one of us. River put lotus lamp, there are some people in a wide variety of light floating in the water, beautiful!
This is the most unforgettable, the most I have a happy Mid-Autumn festival!

關(guān)鍵詞:車間調(diào)度 粒子群算法 求解柔性
中圖分類號(hào):TP301 文獻(xiàn)標(biāo)識(shí)碼:A 文章編號(hào):1007-9416(2016)05-0000-00
柔性作業(yè)車間調(diào)度問(wèn)題[1,2](flexible Job shop scheduling Problem,F(xiàn)JSP),是指帶有機(jī)器可選柔性的車間調(diào)度問(wèn)題。該類問(wèn)題已經(jīng)被證明為NP-hard問(wèn)題,難以取得最優(yōu)解。目前,學(xué)者們對(duì)柔性作業(yè)車間調(diào)度問(wèn)題進(jìn)行了廣泛的研究,并提出了許多算法。主要有模擬退火算法(SA)、禁忌搜索算法(TS)、蟻群算法(ACO)、粒子群算法(PSO)[3]和遺傳算法(GA)等。其中粒子群優(yōu)化算法因其具有通用性強(qiáng)、全局尋優(yōu)和方便實(shí)現(xiàn)等優(yōu)點(diǎn),在求解柔性作業(yè)車間調(diào)度領(lǐng)域有一定的應(yīng)用。本文提出的一種改進(jìn)的粒子群優(yōu)化算法,有效提高了標(biāo)準(zhǔn)粒子群算法求解柔性作業(yè)車間調(diào)度問(wèn)題時(shí)的性能。
1 標(biāo)準(zhǔn)粒子群算法
粒子群優(yōu)化算法(Particle Swarm Optimization,PSO),也稱粒子群算法,是一類基于群體智能的進(jìn)化搜索計(jì)算方法。最早是在1995年由美國(guó)的Kennedy和Ebehart在受到鳥群尋找食物行為的啟發(fā)下共同提出的。算法將所示問(wèn)題的目標(biāo)搜索空間與鳥群的飛行空間相類比,為每個(gè)粒子制定了與鳥類運(yùn)動(dòng)類似的簡(jiǎn)單行為規(guī)則,使得整個(gè)粒子群的運(yùn)動(dòng)與鳥類覓食具有相似的運(yùn)動(dòng)特性,從而用于求解復(fù)雜的優(yōu)化問(wèn)題。
2 改進(jìn)粒子群算法求解FJSP
2.1 編碼
編碼是應(yīng)用粒子群算法求解柔性作業(yè)車間調(diào)度問(wèn)題的關(guān)鍵問(wèn)題,作業(yè)車間調(diào)度問(wèn)題大多采用基于工序的編碼,如下所示為一個(gè)3個(gè)工件在4臺(tái)機(jī)器上加工的部分柔性作業(yè)車間調(diào)度實(shí)例的排序。
粒子的第一維實(shí)向量O可表示為(1 1 1 2 2 3 3 3)。其中第一個(gè)1表示工件1的第一道工序O11,依此類推;粒子的第二維實(shí)向量Xd表示粒子的位置矢量,這里設(shè)由(0,5)之間的數(shù)隨機(jī)生產(chǎn)。將粒子的位置矢量Xd按從小到大的順序進(jìn)行排序,同時(shí)將粒子的第一維實(shí)向量O也隨著Xd的改變而改變,這樣粒子的第一維實(shí)向量就形成了一個(gè)如下加工工序序列:
每道工序可選擇加工時(shí)間最少的機(jī)器,若是最小加工時(shí)間相同可隨機(jī)選擇機(jī)器。
2.2 慣性權(quán)重的選取
本文采取自然指數(shù)自適應(yīng)的慣性權(quán)重選取策略:
式中:G為當(dāng)前迭代次數(shù);Gmax為最大迭代次數(shù)。
3 算法結(jié)果比較
采用10個(gè)具有代表性的FJSP標(biāo)準(zhǔn)算例來(lái)測(cè)試,每個(gè)算例的最大迭代次數(shù)為200,分別獨(dú)立運(yùn)行10次。可以看出,改進(jìn)粒子群算法最優(yōu)解總體優(yōu)于其他三個(gè)算法得到的最優(yōu)解。如表1所示。
4 結(jié)語(yǔ)
本文在標(biāo)準(zhǔn)粒子群算法的基礎(chǔ)上提出了改進(jìn)的粒子群算法,通過(guò)與標(biāo)準(zhǔn)算例的結(jié)果進(jìn)行對(duì)比,證明了本文提出的改進(jìn)粒子群算法不僅提高了標(biāo)準(zhǔn)粒子群算法求解柔性作業(yè)車間調(diào)度問(wèn)題時(shí)的性能,也對(duì)粒子群優(yōu)化算法在求解其它組合問(wèn)題時(shí)提供了理論依據(jù),具有重要的理論價(jià)值與實(shí)際意義。
