【摘要】：伴隨社會(huì)的進(jìn)步和發(fā)展,物料生產(chǎn)和配送已然成為滿足高效生產(chǎn)的必備條件。物料在商品加工的過(guò)程中,能否及時(shí)、精準(zhǔn)、選取科學(xué)方法到達(dá)生產(chǎn)的終端,對(duì)于制造單位的生產(chǎn)物料狀況以及生產(chǎn)加工單位的裝配速率起到關(guān)鍵作用。首先,本文介紹了物料配送相關(guān)理論知識(shí)與方法,包括旅行商模式,車(chē)輛路徑模式,帶時(shí)間窗口的車(chē)輛路徑模式,簡(jiǎn)介聚類方法并給出模糊聚類分組方法,并給出帶時(shí)間窗的車(chē)輛路徑問(wèn)題求解方法,其中特別強(qiáng)調(diào)了遺傳算法。其次,介紹合佳醫(yī)藥車(chē)間物料配送現(xiàn)狀,分析找出存在的問(wèn)題,通過(guò)模糊聚類方法對(duì)研究的樣本進(jìn)行分類劃分,利用模糊聚類方案對(duì)車(chē)間需求點(diǎn)進(jìn)行分組,然后結(jié)合配送目標(biāo)構(gòu)建物料配送數(shù)學(xué)模型進(jìn)行組內(nèi)求解,給出遺傳方法求解結(jié)果和組內(nèi)路徑的排布。最后,給出本文優(yōu)化方案和原有方案的物料配送模式的各指標(biāo)對(duì)比。實(shí)驗(yàn)結(jié)果表明本文方法在物料配送時(shí)間窗,配送距離,物料運(yùn)載裝置的重載率以及總開(kāi)銷都有明顯優(yōu)勢(shì)。本課題可對(duì)同類型企業(yè)物料配送提供有意義的借鑒和參考。
[Abstract]:With the progress and development of the society, material production and distribution has become an essential condition to meet the efficiency of production. Whether the material can reach the terminal of production in time and precision in the process of commodity processing plays a key role in the production material condition of manufacturing unit and assembly rate of production and processing unit. Firstly, this paper introduces the theory and methods of material distribution, including traveling salesman mode, vehicle routing mode, vehicle routing mode with time window, and introduces clustering method and fuzzy clustering grouping method. The method of solving vehicle routing problem with time window is given, especially the genetic algorithm. Secondly, the present situation of material distribution in Hejia Medical Workshop is introduced, the existing problems are analyzed and identified, the samples are classified by fuzzy clustering method, and the demand points of workshop are grouped by fuzzy clustering scheme. Then, a mathematical model of material distribution is constructed to solve the problem in group, and the result of genetic method and the layout of intra-group path are given. Finally, the comparison of each index between the optimization scheme and the original scheme is given. The experimental results show that this method has obvious advantages in material distribution time window, distribution distance, heavy load rate of material carrier and total cost. This topic can provide a meaningful reference for the same type of enterprise material distribution.
