Leagile supply chain: design drivers and business performance implications

In the context of a dynamic and hypercompetitive business environment, effective supply chain design helps organisations to align resources for improved flow of products and services and satisfy customers’ diverse needs. Scholars have proposed several mutually exclusive supply chain designs such as efficient versus responsive, and lean versus agile. Quantitative testing has revealed that supply chain designs of many firms do not match with what was conceptually expected. To address this mismatch, in this study, a new approach to supply chain leagility is introduced and the impact of uncertainty as the key design driver of supply chains on leagility is investigated. The partial least squares (PLS) was employed to analyse data collected from 299 Australian firms by administering a structured questionnaire. Results indicate that higher performance is achievable on minimising the deviation from a balanced supply chain in which aspects of both leanness and agility are equally embedded. Further, the level of uncertainty directly and positively affects the Deviation from Leagility (DFL) index.     

二部制契约下供应链内外部融资模式比较分析

主要对二级响应型供应链的内外部融资模式的对比分析。主要研究的是二级供应链由单一供应商和零售商组成和销售单一产品所面临的资金约束问题。运用数量柔性契约使供应链链条下游企业来考虑内外部融资方式并能够做出最优选择。研究得出,在二级供应链上,影响供应链企业融资的主要因素为供应商和零售商的综合信用。若供应商的信用较好,则采用的融资方式为内部融资,既有利于降低资金使用的成本又可以吸引零售商加大订购产品数量,从而达到供应链绩效整体最优。     

Examination of effect of information sharing on businesses performance in the supply chain process

Nowadays, supply chain management (SCM) has become one of the focal points of competition. The importance of information sharing in SCM is gradually increasing in terms of improving the business performance. In this study, an attempt to determine the effect of information sharing in the supply chain process (SCP) on cost, financial and business performance, in general, was made. The attempt was made by means of a measuring tool which is based on a theoretical approach. For this purpose, the structural equation model (SEM) was established by taking into account the supply chain structure, SCP, supply chain flexibility, environmental uncertainties and information sharing latent structures in businesses and the cost and financial performance indicators. In this study, differently from most other studies, two performance variables were included, and the model was created by defining these variables, which could be measured with more than one indicator, as latent variables. For this purpose, the data obtained from a questionnaire study performed on large firms within the scope of ISO 1000 were used. An attempt to reveal the factors affecting the cost and financial performance of businesses in SCM was made in the study. As a result of the analyses performed, the proposed SEM model was tested by taking into account various compliance criteria, and the validity and reliability of the model were determined.

构建了供应链设计、供应链整合、信息共享及供应链绩效之间关系的理论模型,并以广东省珠三角地区162家制造企业为调查对象,对供应链设计、供应链整合、信息共享及供应链绩效之间的关系进行实证研究。研究结果表明,供应链设计对供应链整合、供应链绩效均有显著的正向影响;供应链设计对信息共享的直接影响并不显著,却会以供应链整合为中介对信息共享产生间接影响;供应链整合对信息共享、供应链绩效有显著的正向影响;而低层次的信息共享对供应链绩效并无显著影响。根据上述实证研究结果,本研究结合中国情境给出了相关管理启示。     

The impact of supply chain disruption on the closed-loop supply chain configuration profit: a study of sourcing policies

A closed-loop supply chain configuration (CLSCC) encompasses the decisions related to the optimal selection of options at each stage of a closed-loop supply chain (CLSC) for the introduction and reconstruction of new products. The extant literature ignores the impact of supply chain disruptions on CLSCC. An attempt is made to fill this gap in this study. Thus, an integrated multi-sourcing CLSCC optimisation model for new and reconstructed products is developed. The optimisation model presented is a mixed-integer nonlinear programming (MINLP) model. Based on a real-world case study of an auto-parts manufacturer in India presented, a comprehensive set of computational experiments, scenario analyses are conducted. The key finding/observation that resulted from our computational experiments is that multi-sourcing generates higher net present value of total profit compared to single sourcing under the risk of supply chain disruption. Several other observations and managerial insights are drawn from computational experiments, and scenario analyses. Firms interested in configuring their CLSC under the risk of supply chain disruption may use the study's outcomes to understand the profit impact of various CLSCC parameters, individually and in combination.     

Examining the influence of supply chain glitches on shareholder wealth: does the reason matter?

This paper investigates how different reasons for supply chain glitches influence shareholder wealth. Prior research indicated that supply chain glitches can decrease shareholder wealth by a staggering 10.28%. We argue that the reason for the supply chain glitch is an important moderator for understanding how supply chain glitches affect shareholder wealth. In this paper we re-assess the effect of supply chain glitches on shareholder wealth for a new time period (i.e. 2001–2012) whilst including the moderators from the original study (growth prospects, firm size, debt-equity ratio and timing) and adding the reason for the supply chain glitch as an important new moderator. Our results show that on average supply chain glitches decrease shareholder wealth by 1.94%. Further, our results indicate that supply chain glitches that arise due to regulatory, catastrophic and infrastructural reasons trigger more significant negative reactions in financial markets as compared with glitches that occur from the supply side. We discuss the implications of our findings both for theory building and for business practice, and end with limitations and suggestions for future research.     

谎报行为下生鲜农产品供应链协调研究

目的研究存在生产商谎报生鲜农产品鲜活度信息的情况下,生鲜农产品供应链的协调问题。方法由单一生产商和单一零售商构成生鲜农产品供应链,其中产品的鲜活度信息为生产商私有信息;基于单周期报童模型,构建供应链各方的利润函数;应用Stackelberg博弈的基本思想,分析供应链上的定价订货决策,并引入收益共享契约进行供应链协调,同时用Matlab软件做数值仿真,以验证结论的有效性。结果生产商的谎报行为会损害供应链系统各方的利润,且谎报因子越低(谎报度越高)对供应链利润的影响越大。引入的收益共享比例在一定范围内时,收益共享契约可以有效地协调生鲜农产品供应链。结论收益共享契约不仅可以有效地协调生鲜供应链,也可以抑制生产商的谎报行为,实现帕累托改进,提高供应链的稳定性。     

供应链伙伴关系、信息共享与企业运营绩效关系

本文以广东省珠三角地区制造企业为调查对象,对供应链伙伴关系、信息共享与企业运营绩效之间关系进行研究.研究结果表明,供应链伙伴关系对信息共享存在显著的正向影响,即增强供应链伙伴关系将有助于提高企业之间信息共享水平;信息共享对企业运营绩效存在显著的正向影响;供应链伙伴关系不仅直接影响企业运营绩效,而且通过信息共享间接地影响到企业运营绩效.另外,我们还发现在供应链伙伴关系中的信任对信息共享与企业运营绩效均有非常显著的影响.本文研究结论可为我国制造企业实施供应链管理策略提供理论指导.     

产品回收再利用率对闭环供应链利润的影响

针对由单个制造商和单个零售商组成的二级闭环供应链系统,制造商委托零售商回收旧产品,然后制造商生产新产品和再制造产品,零售商销售产品.采用stackelberg博弈方法,对制造商占主导的正向供应链和闭环供应链的利润进行了比较,分析了回收再利用率对闭环供应链利润的影响.研究结果表明:在产品存在最低或强制回收要求的前提下,当其他参数不变时,回收再利用率满足一定的阈值,并且回收再利用率越大,制造商实施闭环供应链管理就越有利.
