New batch construction heuristics to optimise the performance of order picking systems

Two new batch construction heuristics called K-means Batching (KMB) and Self-organisation Map Batching (SOMB) are developed and verified by simulation experiments. Both KMB and SOMB have a preferment of superior performance in total travel distance and average picking vehicle utility, and even a conspicuous improvement in total CPU running time. Besides, this paper investigates the overall performance of order picking systems integrating storage assignment, order batching and picker routing to find the optimal policy combinations under different order types. The sensitivity analysis is performed to distinguish the relative importance of the various strategies to enhance the performance of operations management.

An analysis of information overload with implications for survey design research

Abstract

A laboratory‐type experiment was conducted to examine potential information overload causes and solutions. It was found that both information quantity and information complexity are potential causes of information overload. The experiment results also suggested that information overload problems may be reduced through carefully designed information display patterns. When designing survey questionnaires, attention must be given to potential causes of information overload. Methods of presenting information that ameliorate information overload must also be considered. As demonstrated in this study, survey designs can be tested in controlled, laboratory‐type experiments. The results of these experiments can then be used to improve the design of field survey questionnaires.     

Analysis of Korean millennials’ travel expenditure patterns: an almost ideal demand system approach

ABSTRACT

Generational cohorts can differ in their consumption patterns and preferred travel behavior. As the millennial generation represents an important economic force and influences new consumption trends, this study utilizes nationwide data and almost ideal demand system (AIDS) approach to examine expenditure patterns of Korean travelers during holidays. In this process, the joint effects of travel-related characteristics are also examined. The results of the AIDS estimation on data from 871 domestic travelers reveal significantly different travel expenditure patterns for cohorts. The findings contribute to furthering the understanding of how different generational cohorts allocate their travel budgets to respective travel expenditure categories.     

当前我国公共行政范式的构建与发展

当前服务型政府建设遇到很多技术问题。特别是大部制改革背后进一步转变政府职能。要求必须对当前我国公共行政范式建设深入思考。根据公共行政的发展趋势及西方政府的发展经验，我国公共行政范式处在旧范式的基础正在破碎。新范式基础尚未建立的阶段。该阶段的范式构建要以现代管理型政府为基础与以服务型政府为导向并重，借鉴西方政府建设实践，关注我国政府发展的实际状况。
