The adaptive approach for storage assignment by mining data of warehouse management system for distribution centres

Among distribution centre operations, order picking has been reported to be the most labour-intensive activity. Sophisticated storage assignment policies adopted to reduce the travel distance of order picking have been explored in the literature. Unfortunately, previous research has been devoted to locating entire products from scratch. Instead, this study intends to propose an adaptive approach, a Data Mining-based Storage Assignment approach (DMSA), to find the optimal storage assignment for newly delivered products that need to be put away when there is vacant shelf space in a distribution centre. In the DMSA, a new association index (AIX) is developed to evaluate the fitness between the put away products and the unassigned storage locations by applying association rule mining. With AIX, the storage location assignment problem (SLAP) can be formulated and solved as a binary integer programming. To evaluate the performance of DMSA, a real-world order database of a distribution centre is obtained and used to compare the results from DMSA with a random assignment approach. It turns out that DMSA outperforms random assignment as the number of put away products and the proportion of put away products with high turnover rates increase.

深入认识消费现状,提高农村居民消费水平

分配和消费一直都是影响经济发展的两个重要因素,同时分配和消费又相互影响着对方。尤其在现在爆发全球性金融危机的情况下,我国的经济发展面临着国外需求萎缩,国内需求有限的艰难局面。因此如何扩大消费,促进经济又好又快发展成为当前经济工作的重点。本文主要通过分配和消费两者关系的论述来分析通过分配扩大消费促进经济的理论依据。

Task assignment and organizational form

This paper shows that a firm prefers a process-based task assignment compared to a function-based one if the tasks are from functional areas which are neither too complementary nor too substitutable. We consider several projects (processes) with contributions from several functional areas. The organization can be structured along processes like product lines (M-form) or along functional areas like marketing or production (U-form). The U-form enables cost savings due to specialization or scale economies. The more effective incentives under the M-form might outweigh these savings if the functions are neither too complementary nor too substitutable.
