【摘要】 本文以板式定制衣柜企业人工拣货作业为研究对象,首先通过对待分拣的零件堆特征进行分析,总结出该企业分拣作业的特点,确定合适的效能评价指标。其次,根据国内外对订单分拣的研究,结合板式衣柜零件分拣特点,利用启发式算法构建适用于人工分拣板式零件的分拣模型。具体来说论文研究成果如下:(1)根据关联规则将不同零件类型聚类,划分出侧板类、踢脚板类和抽屉板类三种零件堆。确定不同零件类型面积分布规律,并根据分拣和合并动作区分出大板、中板和小板三种板件类型。(2)区分不同零件堆类型建立了分拣时间与分拣数量关系。大板类零件分拣时间关系为y=26.454x-5.396;中板类零件分拣时间关系为y=11.835x-2.3108;小板类零件分拣时间关系为y=0.661x2+9.1885x+6.3703;除小板类关系中x为产品数量,其它关系中x为零件数量,y单位为人·秒。(3)建立合并规则并区分不同零件类型确定合并时间与零件数量关系。大板件类零件合并时间关系为y=4.2698x-0.64083;中板件类零件合并时间关系为y=1.7876x-3.3688,当x<4时,y=1.5x;小板件类零件合并时间关系为y=0.51178x+0.4038,三者关系中x为零件数量,y单位为人·秒。(4)在启发式算法思想的指导下,利用种籽算法和关联规则对生产过程中产生的小批量多品种零件堆的流转方式进行指导分堆。提出种籽零件堆的选择方法和分批规则,为检验分拣效能,用算例展示了其求解方法,并证明了两种算法对板式零件分拣效能有提升作用。(5)建立了以最小化分拣区域占用量为目标的零件分拣顺序模型,在节约算法思想的指导下,提出了分拣占用面积和时间计算方式,建立了分拣顺序模型和算法实现流程。在此基础上,通过实际数据的计算对分拣顺序模型进行了检验。更多还原

【Abstract】 Artificial sorting of plate custom closet enterprise is the research object of the paper.Firstly,with the analysis of part heap feature, the paper summarized the characteristics of the enterprise sorting job and determined the appropriate efficiency index. Secondly, according to domestic and foreign researches of order picking, constructed sorting model suitable for manual sorting plate parts with heuristic algorithm combined plate wardrobe parts sorting features. Specifically, the paper made the following innovative work:(1) According to association rules clustering of different types of parts, parts set were divided into three kinds such as side panels, drawer panels and skirtboards. Considering sorting and merging rules, parts were divided into three kinds such as larger part, medium part and smaller part when distribution of different types of part was known.(2) Relationship between sorting-time y and sorting-number x was established by distinguish different parts set. Relationship between sorting-time and number was y=26.454x-5.396 when sorting bigger parts. And the relationship was y=11.835x-2.3108 when sorting medium parts. X was used to represent number of parts. Relationship was y=0.661x2+9.1885x+6.37 when sorting smaller parts, and x was used to represent number of products.(3) Relationship between combining-time y and number x was clearly known by establishing combined rules. Relationship between combining-time and number was y=26.454x-5.396 when combining bigger parts, y=1.7876x-3.3688 when medium parts, y=0.51178x+0.4038 when smaller parts. Relationship was y=1.5x, if number of medium parts was greater than 3. X was used to represent number of parts and y second · person.(4) Under the guidance of the idea of heuristics, circulation method of small quantities and many varieties of part heap produced in production process was guided to stock piles with seed algorithms and saving and algorithms. Proposed selection methods and batch rules of part seeds heap, sorting evaluation function is proposed to test the efficiency of sorting. Specific numerical calculation proved that two algorithms can enhance sorting efficiency of plate parts.(5) Part sorting order model with the goal to minimize the space occupied was established.Calculation method of area and time occupied by sorting was proposed, sorting order model and evaluation function was established. Based on this, sorting order model was validated with the calculation of actual data.更多还原
