针对江苏沿海条子泥区域泥沙,运用控制剪切速率实验方法,通过改变样品中的粉沙质量占比,系统探究了泥沙的级配对其剪切应力和黏度的影响规律,并使用剪切速率扫描法和间接法分别计算泥沙样品静态和动态屈服应力。结果表明:所有组次泥沙样品均表现出两次明显的屈服行为,其流变特性以两个屈服行为为界,划分为3个阶段;泥沙样品中粉沙含量对其流变特性起着关键性作用,粉沙含量增大,样品剪切应力和黏度均发生相应减小,其中粉沙含量在35%~55%区间内变化梯度较大,此区间可能存在泥沙粒间主导作用力的转变;最后依托剪切速率扫描法测得的实验数据分析,得到了不同粉沙含量下泥沙的静态屈服应力和动态屈服应力的经验公式。

Manual Order Picking Route Optimization in Distribution Warehouse of Chain Furniture Retail Enterprise

引用

American Journal of Operations Research 2024年第3期14卷 105-136页

作者： Yongzhen Zeng Junkun Wang Ching-Kuei kao King-Zoo Tang Department of Logistics Management Fujian University of Technology Fuzhou China Key Laboratory of LNG Industry Chain Fujian University of Technology Fuzhou China Department of Information Management National Chung Cheng University Chiayi China

Due to the effects of the COVID-19 pandemic and the rise of online shopping, the offline sales of IKEA Fuzhou have been declining since 2020. Because the cost of distribution warehouse is a major expense for offline chain furniture retailers, and the picking process is a key activity in distribution warehouse operations. To reduce the cost of distribution warehouse and alleviate the survival pressure of the offline chain furniture retailers, this paper focuses on optimizing the picking route of the IKEA Fuzhou distribution warehouse. It starts by creating a two-dimensional coordinate system for the storage location of the distribution warehouse using the traditional S-type picking strategy to calculate the distance and time of the sorting route. Then, the problem of optimizing the picking route is then transformed into the travelling salesman problem (TSP), and picking route optimization model is developed using a genetic algorithm to analyze the sorting efficiency and picking route optimization. Results show that the order-picking route using the genetic algorithm strategy is significantly better than the traditional S-type picking strategy, which can improve overall sorting efficiency and operations, reduce costs, and increase efficiency. Thus, this establishes an implementation process for the order-picking path based on genetic algorithm optimization to improve overall sorting efficiency and operations, reduce costs, increase efficiency, and alleviate the survival pressure of pandemic-affected enterprises.
