供应链核心在于实现供应链环节中的信息沟通,数据互换和协同工作,改造和整合企业的业务流程,因此供应链系统模型应该具有动态可重构的特点,系统主体的构成也应反映这种思想,在系统中引入“大规模定制”,“工作流”的新思想和“异构系统兼容”,“通用报表”以及“三层架构应用体系及开发手段”等新技术将使供应链系统更为“敏捷”。  相似文献

说明了均匀、轴对称、无源介质是一个K-辛空间上的Hamilton系统,Hamilton函数是系统的守恒量;数值计算辐射强度角分布的合理途径是将辐射迁移方程离散成以离散Hamilton函数为守恒量的有限维K-辛空间上的正则方程,并采用保离散Hamilton函数守恒的K-辛算法数值求解.  相似文献

This paper investigates the existence of a correction mechanism for mis-pricing between Japanese stock and bond. By this correction mechanism we mean that when deviations occur from the equilibrium levels of the expected return differentials between stock and bond — the risk premium differentials, the market will tend to correct the mis-pricing and bring the expected return differentials back to the equilibrium levels. We assume that the yield spread between the predicted earnings price ratio of stock and the yield to maturity of bond reflects the risk premium between stock and bond, and estimate the equilibrium risk premium differentials and mis-prices between stock and bond by modelling their behaviors with a statistical yield spread model (SYS). Empirical results strongly indicate the existence of the mis-pricing correction mechanism, suggesting the inefficiency of securities markets.  相似文献

Based on the analysis of the need of a new coordinating mechanism in cyber-value chain, this paper puts forward a cyber-coordinating mechanism, which is a mechanism between market mechanism and firm hierarchical mechanism. It is the theoretical basic point for setting up the system of Strategic Management Accounting in cyber-value chain. This paper conducts the model of Strategic Management Accounting based on cyber-coordinating mechanism, and presents evidence from a case study that was conducted to understand the impact of disintegration on original suppliers and of reintegration on new suppliers in order to support our cyber-coordinating mechanism hypothesis and the application value of the new model of strategic management accounting in cyber-value chain.  相似文献

Setting operating policies for supply hubs   总被引:6,自引:0,他引:6  
This paper deals with the joint management of operations at the supply hub for the customer and the upstream supplier. Different operating conditions are considered, namely, backordering, minimum and maximum specified inventory levels. Some analytical insights on better managing suppliers operating under a vendor managed inventory program are presented. Essentially, we show that the penalty cost imposed on over- and under-stocking, and the min–max policy for hub inventory reside in the power of the hub operator. The relationship between supply hub policy and performance measures is quite complex and non-linear in nature. We suggest a structured hierarchical approach which can help supply hub in achieving balance between various parties involved in chain. A numerical example and an algorithm are included to highlight this result.  相似文献

Along with the development of Chinese social economy and the innovation of government policy, Chinese Architectural Industry is playing a more and more vital role in the entire national economy. This paper first abstracts the connotation and basic characteristic of the Architectural Industry, then discusses the present situation of the development of Chinese Architectural Industry and carries on the analysis on the entire construction industry. Finally discusses the development tendency of Chinese architectural industry, and put forward the corresponding policy proposals to its developmental strategy.  相似文献

Graphical models provide a powerful and flexible approach to the analysis of complex problems in genetics. While task-specific software may be extremely efficient for any particular analysis, it is often difficult to adapt to new computational challenges. By viewing these genetic applications in a more general framework, many problems can be handled by essentially the same software. This is advantageous in an area where fast methodological development is essential. Once a method has been fully developed and tested, problem-specific software may then be required. The aim of this paper is to illustrate the potential use of a graphical model approach to genetic analyses by taking a very simple and well-understood problem by way of example.  相似文献
