Customer-facing supply chain practices—The impact of demand and distribution management on supply chain success

Traditionally, distribution has been viewed as the key (physical) link between a company's internal supply chain activities and its customers. More recently, demand management has emerged as a new dimension at the customer interface. Although it has become increasing popular in industry, it has not yet been analyzed in depth with respect to its impact on supply chain performance. Both distribution management and demand management entail customer-facing processes and practices and that are interrelated and (may) jointly determine supply chain performance. In this paper we seek to extend the stream of research in supply chain management by systematically investigating the impact of customer-facing supply chain practices on supply chain performance. Specifically, the paper examines the relative impact of relevant practices associated with demand and distribution management. To this end, we collected data from 116 multi-national companies based in Europe and analyzed it using structural equation modeling techniques. Our results suggest that (i) high demand management performance has a substantial positive impact on the overall supply chain performance, (ii) this effect is stronger than that of distribution management performance, and (iii) there is no evidence that demand management might be an enabler for effective distribution management. Among the individual practices that constitute demand and distribution management, adherence to the demand and distribution management processes and demand segmentation emerged as the strongest performance levers. Based upon additional in-depth interviews conducted with selected companies from our sample, we shed light on some of the most important findings that emerged from our survey analysis.     

从京津冀协同网络看河北县域农业经济发展模式

[目的]京津冀协同发展战略,是河北农业经济发展定位的基本视角,而在区域协同发展中,县域发展是重点也是难点,河北县域农业经济发展是河北省农业经济发展的基本面。[方法]在京津冀协同发展视域下,分析近年来河北省11个市农业经济发展面临的问题,整体上提出对接京津的顶层设计方案。进而从县域发展角度,以县域为突破口,将河北省173个建制县分为两类:距京津较远的146县以及环京津27个交界县,分别提出农业经济发展的具体模式。[结果]在京津冀协同发展中,河北县域农业经济发展需注重以下几点:(1)高度重视顶层设计;(2)以特色农业为抓手,科学规划农业功能园区,对接京津协同发展;(3)利用市场机制与科技机制,打造农业产业化模式,通过河北县域与京津农业协同大数据网的技术保障作用,提升河北农业经济整体实力。[结论]基于京津冀协同发展战略,找出推进河北县域农业经济发展的新模式,具有重要的现实意义。     

Advance transit oriented development typology: case study in Brisbane,Australia

Internationally, transit oriented development (TOD) is characterised by moderate to high density development with diverse land use patterns and well connected street networks centred around high frequency transit stops (bus and rail). Although different TOD typologies have been developed in different contexts, they are based on subjective evaluation criteria derived from the context in which they are built and typically lack a validation measure. Arguably there exist sets of TOD characteristics that perform better in certain contexts, and being able to optimise TOD effectiveness would facilitate planning and supporting policy development. This research utilises data from census collection districts (CCDs) in Brisbane with different sets of TOD attributes measured across six objectively quantified built environmental indicators: net employment density, net residential density, land use diversity, intersection density, cul-de-sac density, and public transport accessibility. Using these measures, a Two Step Cluster Analysis was conducted to identify natural groupings of the CCDs with similar profiles, resulting in four unique TOD clusters: (a) residential TODs, (b) activity centre TODs, (c) potential TODs, and (d) TOD non-suitability. The typologies are validated by estimating a multinomial logistic regression model in order to understand the mode choice behaviour of 10,013 individuals living in these areas. Results indicate that in comparison to people living in areas classified as residential TODs, people who reside in non-TOD clusters were significantly less likely to use public transport (PT) (1.4 times), and active transport (4 times) compared to the car. People living in areas classified as potential TODs were 1.3 times less likely to use PT, and 2.5 times less likely to use active transport compared to using the car. Only a little difference in mode choice behaviour was evident between people living in areas classified as residential TODs and activity centre TODs. The results suggest that: (a) two types of TODs may be suitable for classification and effect mode choice in Brisbane; (b) TOD typology should be developed based on their TOD profile and performance matrices; (c) both bus stop and train station based TODs are suitable for development in Brisbane.     

A supply chain-transport supernetwork equilibrium model with the behaviour of freight carriers

This paper presents a supernetwork equilibrium model integrating supply chain networks with a transport network, namely, a supply chain-transport supernetwork equilibrium model. The model takes into account the behaviour of freight carriers and transport network users to endogenously determine the transport costs generated in the supply chain networks. The interaction between transport network and supply chain networks can also be examined. Results of the numerical tests reveal that the improvement of transport network could enhance the efficiency of supply chain networks. The paper makes contributions to modelling of supply chain networks as well as to that of transport networks.     

完美货币与完美经济

没有完美的货币或者完美的经济组织形式。欧元和欧元区经济的问题,都是在全球化过程中所必须经历的阶段。一个好的经济体制,应该使＂国民生活水平＂最大化。但是,如果要具体到现实世界,＂生活水平最大化＂往往意味着很多,很可能意味着对其他经济体利益的侵蚀。本文从信用约束、经济一体化等角度,论述了欧元的使用对欧元区经济的益处;并指出了欧元使用带来的南欧国家财政赤字和贸易逆差问题。中国对外投资应该辩证地看待欧美经济体的长处和不足,合理配置外汇资产的比例。     

Enhancing hospital supply chain performance: A relational view and empirical test

Improving hospital supply chain performance has become increasingly important as healthcare organizations strive to improve operational efficiency and to reduce cost. In this study, we propose a research model based on a relational view, delineating the factors that influence hospital supply chain performance: trust, knowledge exchange, IT integration between the hospital and its suppliers, and hospital–supplier integration. Testing results of the research model based on data from a sample of 117 supply chain executives from U.S. hospitals show positive direct effects: (1) from trust and from IT integration to knowledge exchange respectively; (2) from knowledge exchange and from IT integration to hospital–supplier integration respectively; and (3) from hospital–supplier integration to hospital supply chain performance. The results also show the following indirect effects: (1) the influences of knowledge exchange and IT integration on hospital supply chain performance are partially and fully mediated by hospital–supplier integration, respectively and (2) the influences of trust and IT integration on hospital–supplier integration are fully and partially mediated by knowledge exchange, respectively. In addition, the results show the following moderating effects: (1) hospital system membership moderates the relationships between IT integration and knowledge exchange and between trust and knowledge exchange; (2) hospital environmental uncertainty moderates the relationship between trust and knowledge exchange; and (3) trust moderates the relationship between knowledge exchange and hospital–supplier integration. Implications of the study findings and directions for future research are discussed.     

Pricing decision for substitutable products with retail competition in a fuzzy environment

This paper studies the pricing problem of substitutable products in a supply chain with one manufacturer and two competitive retailers. The consumer demands and manufacturing costs are of uncertainty, which are described by fuzziness. Based on different market structures, one centralized pricing model and three decentralized pricing models are developed, and the corresponding analytical equilibrium solutions are obtained using the game-theoretic approach. Finally, numerical examples are presented to illustrate the effectiveness of the theoretical results, and to gain additional managerial insights.
