A study on X party material flow: the theory and applications

A thorough study of X party material flow (XPMF), its theory and its applications is conducted in this research. The X material flow concept is an extension of the material flow (MF) theory. To further elucidate that XPMF is one type of MF service model with PMF (party, material, flow) fractal structure and the characteristics of XPMF, we develop the three-pyramid synergetic operational model of XPMF. Through the analysis of several cases, we believe that OIR (Objective relational grade, Information sharing grade, and Resource complementary grade) is the set of order parameters that control and determine the formation of XPMF new structure and its degree of being ordered. Therefore it reveals the mechanism of XPMF formation and evolution. We also provide the principles and the methods for XPMF control.     

Supply Chain Management Competency and Firm Financial Success

Supply chain management (SCM) plays a major role in creating (or destroying) shareholder value by influencing the three major drivers of firm financial performance: revenue, operating costs, and working capital. Yet, the relationship between SCM competency and firm financial performance is not well‐established. Drawing on the resource‐based view of the firm, this study assesses this relationship using Delphi‐style opinion data from AMR Research’s Supply Chain Top 25 rankings to assess SCM competency and Altman’s (1968) Z‐score statistic as the measure of financial success. The study findings show that firms recognized by industry experts for SCM competency have significantly higher Z‐scores than their close competitors and industry averages.

DEVELOPING SOCIAL IDENTITY AND SOCIAL CAPITAL FOR SUPPLY CHAIN MANAGEMENT

Competition involves not firm against firm but rather supply chain against supply chain, but few studies explain theoretically the subsistence of a supply chain as a social entity or the operating mechanisms through which firms socialize to obtain better business performance. On the bases of social identity theory and social capital theory, the authors suggest that the salience of supply chain identity accumulates social capital in a supply chain, which then facilitates supply chain management and improves business performance.     

价格、时间敏感性供应链收益混合分配契约模型研究

供应链企业通过何种契约方式进行协同合作，以达到整体目标的最优，是供应链管理的一个重要研究课题。在一个两阶供应链系统中，面对价格和响应时间敏感性市场需求，文章通过引入供应商的激励——响应时间函数和市场关于价格和响应时间的需求函数，构建了供应链的收益混合分配契约模型，最后文章给出了算例分析，验证了该模型的可行性。
