摘 要
隨著社會(huì)的發(fā)展與進(jìn)步，消費(fèi)者的需求越來(lái)越多元化，原來(lái)福特式的大批量生產(chǎn)同一種產(chǎn)品的模式已經(jīng)越來(lái)越不能滿足消費(fèi)者多樣化的需求，消費(fèi)者需求與企業(yè)生產(chǎn)之間的不匹配日益明顯。對(duì)于制造業(yè)而言，面對(duì)著市場(chǎng)多變以及全球化的激烈競(jìng)爭(zhēng)，必須緊跟時(shí)代的腳步，改變以往落后的生產(chǎn)模式。單元制造是近來(lái)被高度重視的一種先進(jìn)的制造模式，通過(guò)應(yīng)用成組的方式實(shí)現(xiàn)從傳統(tǒng)批量生產(chǎn)或加工車(chē)間生產(chǎn)到流水線式的生產(chǎn)。單元制造不僅具有車(chē)間生產(chǎn)的靈活性，又具有流水線生產(chǎn)的高效率，能更滿足當(dāng)今生產(chǎn)趨向中小規(guī)模批量的加工模式，更能滿足實(shí)際的需要。單元制造通過(guò)應(yīng)用成組技術(shù)，把生產(chǎn)設(shè)備和零部件按照一定的規(guī)則，把相似的設(shè)備和零部件布置在同一車(chē)間內(nèi)，最大限度的提高設(shè)備的利用率和產(chǎn)品質(zhì)量。
本論文介紹單元制造，以及單元制造系統(tǒng)實(shí)現(xiàn)過(guò)程中所常用的智能方法，并著重研究運(yùn)用遺傳算法來(lái)求解單元形成問(wèn)題。通過(guò)模擬遺傳算法中的選擇復(fù)制，交叉，變異，應(yīng)用適應(yīng)值，求解目標(biāo)函數(shù)，找出最佳的單元布置方案。

ABSTRACT
With the development and progress of the society, the consumer demand has become more and more diversified, the original Ford-style mass production model of the same product has become increasingly incapable to meet the diversified needs of consumers. The mismatch between consumer demand and production is serious. The manufacturing industry faces the challenge of market competition and globalization. To keep up the pace of the times, we must change the production modes in the past. Cellular manufacturing（CM） is an advanced manufacturing mode with a high attention in recent years, through the application of group technology to convert the traditional mass production or processing plant to the line-style production. Cellular manufacturing not only has the flexibility of the workshop production, but also has high efficiency of production line, so it can meet the current trend of small and medium batch processing mode, and can meet the actual needs better.
Through the application of group technology, equipments and parts are assigned into cells according to certain rules. Cellular manufacturing can maximize the equipment utilization and product quality.
In this paper, cellular manufacturing and the commonly used intelligent methods in the implementation of cellular manufacturing systems are analyzed, and the genetic algorithm is applied to solve the cell formation problem. Through simulation of the selection crossover and mutation of the genetic algorithm, with the application of the fitness application, to solve the objective function and find the best solution of the cell layout.
Key words: celluar manufacturing，intelligent method，genetic algorithm
