供应链合作关系对供应链绩效的影响——基于长三角企业的实证研究

供应链合作关系中的信任和未来期许均对于供应链运作绩效中的产品质量和客户服务水平具有正向影响作用,而对于产品具有负向作用。但是供应链合作关系中的合作意愿仅仅对于产品质量和客户服务水平具有正向影响作用,但是对于成本的影响没有通过原来的假设。因此对于企业而言,要提高供应链运作绩效的水平,应综合考虑供应链合作关系的维度,可根据实际情况加强各种合作行为,全面提升双方合作的绩效。     

Evidence of the impacts of public e-procurement: The Portuguese experience

This paper analyses public e-procurement implementation and emphasizes its main difficulties and impacts in relation to the type of public organizations. The primary impacts and changes in the Portuguese public sector are analyzed within the new legal framework, which adopts mandatory e-procurement for any open, restricted or negotiated procedure. In this sense, two surveys carried out in consecutive years were conducted to assess the implementation difficulties and impact of e-procurement in the Portuguese public sector.The major value of this research is that it presents and discusses, for the first time, evidences about difficulties and impacts on the mandatory adoption of public e-procurement, based on the case of Portugal. The results show that the entities’ administrative level influences the e-procurement implementation, which is influenced by the innovation adoption process.     

Building long-term orientation in buyer–supplier relationships: The moderating role of culture

This research investigates buyer–supplier relationships in international markets. Research and practice have shown that buyer–supplier relationships benefit when partners to the relationship exhibit a long-term orientation. The extant literature suggests that a buyer's trust of a supplier and the supplier's performance affect the buyer's long-term orientation toward the relationship. We propose that the relative effects of trust and performance on long-term orientation are moderated by culture – specifically the individualism/collectivism dimension. Hypotheses are tested on data from two individualist and two collectivist cultures, using responses from over 600 purchasing professionals in the United States, Anglophone Canada, Francophone Canada and Mexico. Taken together, empirical findings suggest that cultural differences warrant consideration in developing successful purchasing strategies.     

RESPONDING TO DISRUPTIONS IN THE SUPPLY NETWORK‐FROM DORMANT TO ACTION

Managing risks in supply networks is a complex task; more so in those supply networks where the core competence lies in dealing with natural disasters, complex emergencies, and large‐scale attacks—namely those of humanitarian, and military organizations where the price of failure can be counted in terms of the loss of life rather than, simply, reduced profits. This conceptual article examines the capabilities of these supply networks to manage such disruptions, based on their resource configuration in a dormant preparation state. The article concludes by presenting how different types of supply networks can manage large‐scale disruptions.     

LOGISTICS AND SUPPLY CHAIN MANAGEMENT APPLICATIONS WITHIN A GLOBAL CONTEXT: AN OVERVIEW

This paper reviews 726 academic research studies covering logistics and supply chain management (L'SCM) applications within a global context. Articles are analyzed according to their publication year and outlet, common themes, and countries or regions investigated. The sample was drawn from the ABI/INFORM Global database, which includes almost 1,800 journal titles. The review offers a starting point for researchers, graduate students, faculty members or practitioners examining international L'SCM applications. The article also draws attention to the wide array of global L'SCM studies conducted, their settings and viewpoints. Additionally, this paper highlights some of the most interesting works and draws attention to lesser‐researched countries and regions of the world. The overview also provides an introduction for practitioners and managers to what academic research has covered in the area of global L'SCM. Practitioners can use this review as a starting point for the identification of relevant and useful references for their particular task.     

Determining an optimal hierarchical forecasting model based on the characteristics of the data set: Technical note

The efficient flow of goods and services involves addressing multilevel forecast questions, and careful consideration when aggregating or disaggregating hierarchical estimates. Assessing all possible aggregation alternatives helps to determine the statistically most accurate way of consolidating multilevel forecasts. However, doing so in a multilevel and multiproduct supply chain may prove to be a very computationally intensive and time-consuming task. In this paper, we present a new, two-level oblique linear discriminant tree model, which identifies the optimal hierarchical forecast technique for a given hierarchical database in a very time-efficient manner. We induced our model from a real-world dataset, and it separates all historical time series into the four aggregation mechanisms considered. The separation process is a function of both the positive and negative correlation groups' variances at the lowest level of the hierarchical datasets. Our primary contributions are: (1) establishing a clear-cut relationship between the correlation metrics at the lowest level of the hierarchy and the optimal aggregation mechanism for a product/service hierarchy, and (2) developing an analytical model for personalized forecast aggregation decisions, based on characteristics of a hierarchical dataset.     

UNDERSTANDING THE FINANCIAL CONSEQUENCES OF THE BULLWHIP EFFECT IN A MULTI‐ECHELON SUPPLY CHAIN

This article is concerned with how supply chain strategies can mitigate the Bullwhip Effect and inflated inventories from the perspective of the central firm (typically a manufacturer) in the supply chain. We first outline a base case scenario with a validated system dynamics simulation model, using supply chain characteristics as reported by a real firm, in this case a Mexican electronics supplier to U.S. automobile assemblers. We find, surprisingly, that a lower Bullwhip Effect Index (BE) does not always lead to lower costs in the supply chain studied. Furthermore, sensitivity analysis suggests some interesting, counterintuitive results. The implications of these findings are further developed as we test how lead time reduction can also reduce the Bullwhip Effect in the simulated setting.     

DO PERCEPTIONS BECOME REALITY? THE MODERATING ROLE OF SUPPLY CHAIN RESILIENCY ON DISRUPTION OCCURRENCE

The concern and study of supply risk and supply continuity has recently come to the forefront in managing business and conducting research. This empirical study of U.S. and German firms investigates the relationship between perceived supply risk sources and supply disruption occurrence, as well as the use of supply chain resiliency practices to reduce disruption frequency. We demonstrate that supply managers' concerns with risk emanating from suppliers and the supply market are positively related to supply disruption occurrence. We further show how and when implementing flexibility and redundancy may reduce the effects of supply disruptions.     

新疆企业用工需求与劳动力供给问题调查研究

发展是第一要务，是解决新疆一切问题的基础。中央新疆工作座谈会的召开，19个省市的大力支持，以及中央出台的一系列特殊优惠政策和措施，为新疆大建设、大开放、大发展提供了前所未有的历史机遇。疆内众多企业在此大环境下抓住有利时机，增加订单，扩大产能，千方百计加快发展。此时企业用工需求量也在大幅增加，出现了“招工难”、“用工荒”的社会现象，已影响到企业的生产经营和发展前景。本文立足新疆实际，采用问卷调查的方法，对当前企业用工和劳动力供给状况以及存在的问题开展调查研究，深刻剖析了企业劳动力供给与需求不匹配的原因和症结，并提出政策建议。     

A centralized/decentralized design of a full return contract for a risk-free manufacturer and a risk-neutral retailer under partial information sharing

We consider the design of full return contract in a simple supply chain with a risk-free manufacturer and a risk-neutral retailer. In this problem, the ordering quantity and the rebate price for unsold products are determined by the retailer and the manufacturer, respectively. We propose an optimal solution procedure in centralized and decentralized decision making environments considering when the information sharing among the retailer and the manufacturer is partial. We provide numerical examples to explain the proposed solution procedures.
