有序样本聚类法在SLP物流强度等级划分中的应用

Application of ordered sample clustering method in systematic layout planning classification of logistics strength

工业企业总平面布置是在一定条件下对厂区内的各个建构筑物进行合理的布置,美国的缪瑟提出一种程序化的工厂布置方法即系统化布置方法(SLP).该方法中多次应用到A-U等级划分方法,如作业单位间的物流强度大小A-U等级划分、作业单位间的非物流关系密切程度A-U等级划分等,A-U等级划分法在该布置方法中发挥了重要的作用,而传统划分A-U等级采用的原则为经验比例法,针对由经验比例法确定A-U等级分类的主观性、模糊性和不确定性.尝试采用有序样本聚类法对A-U等级进行划分,将有序样本聚类法中的最优分割思想应用于物流强度分类划分中,使分类后各段内部样品之间的差异最小,而各段样品之间的差异较大.与经验比例法相比该分类方法更加科学、客观、合理,最后运用该算法对某一机械厂的物流强度进行等级分类,得出分类结果,证实该算法的可行性和有效性.

Industrial enterprise general layout means decorating the buildings in each area of the factory reasonable under certain conditions. Richard Muther from America proposed a procedural plant layout method： Systematic Layout Plan- ning. The A-U hierarchies method was applied in SLP, dividing the size of the logistics strength grading between operat-ing units use A-U method, dividing the degree of non-logistics between operating units using A-U method and so on. A- U hierarchies method has played an important role in SLP. But they always use the experienced proportion method as the principle of A-U dividing level. In view of the fact that A - U dividing level determined by the experienced proportionmethod are always subjectivive, ambiguous and uncertain this paper attempts to apply ordered sample clustering method in dividing the intensity level of logistics, applying the optimal bipartition thought of the ordered sample clustering in logis- tics strength classification, so that the samples within each section of the difference between the minimum and each sectionof the large difference between the sample. Compared with the experience proportion method, the ordered sample cluste- ring method is more scientific, objective and reasonable, Using the algorithm to a practical example of the classification of logistics strength in a machinery factory, it is concluded that the algorithm is both feasible and effective.
