主体风险规避情形下多属性逆向拍卖利润分配研究

本文针对采供双方风险规避的多属性逆向拍卖环境下的利润分配与采供关系建立问题,构建了非合作与合作博弈模型,分析了主体风险态度对利润分配结果的影响,得出建立和发展合作关系的条件,并确定了利润最优分配比例。结合仿真实验得出：1）采供双方非合作时,影响双方利润的因素：供应商成本参数,参与拍卖的供应商数量等。2）双方合作时,对利润的分配比例,受双方风险规避系数的影响;采购商提供给供应商的补贴受双方风险规避系数和讨价还价能力的影响。3）双方建立合作的基本条件需同时满足集体理性和个体理性,而长期合作的必要条件是双方效用最大化前提下的确定最优分配比例。     

Universal supplier selection via multi-dimensional auction mechanisms for two-way competition in oligopoly market of supply chain

Allocation of the tasks in competitive market conditions at each echelon of the supply chain is an important activity in the supply chain. The task allocation problem, referred to as supply chain formation process, normally faces information asymmetry in the supply chain. The information asymmetry is caused by rational and intelligent players trying to maximize their own profit rather than opt for the supply chain profit as a whole. Thus, the process of allocating tasks in such situations becomes difficult and will result in externalities in the supply chain trades. These externalities can be internalized with present methodologies in the literature. In this paper, the major internalization methods in different contexts are considered. Lagrange relaxation and Vickery Clarke Groves (VCG) auction mechanism are explored in order to form a supply chain. This paper proposes the multi-stage auction mechanism analyzing two-way competitions, a Bertrand and Cournot competition where price per unit and quantity are the underlying two parameters in a utility analysis. To analyze the problem in real life, the industry example of Indian Railway Catering and Tourism Corporation Ltd. (IRCTC) procurement process has been taken which demonstrates the usability of the proposed framework.

基于集成供应的RS契约协调模型研究

在由供应商和制造商组成的两级供应链中引入集成商,研究了需求不确定且价格敏感条件下基于集成供应的3级供应链的协调问题,建立了满足渠道协调条件和集成供应条件的RS契约协调模型,给出了模型中RS契约参数的取值范围和取值过程,并用实例加以说明。利用模型不仅可以确定产品的生产量和销售价格,而且还可以通过RS契约参数实现供应链利润的分配。     

Cost Allocation in Manufacturing–Remanufacturing Operations

For firms remanufacturing their products, the total life‐cycle costs and revenues from new and remanufactured products determine their profitability. In many firms, manufacturing/sales and remanufacturing/remarketing operations are carried out in different divisions. Each division is responsible for only part of the product's life cycle. Practices regarding transfer pricing across divisions vary significantly among companies, affecting the life‐cycle profit performance of the product. In this research, we identify characteristics of transfer prices that achieve the firm‐wide optimal solution. To this end, we consider a manufacturer who also undertakes remanufacturing operations and we focus on price (quantity) decisions. We determine that a cost allocation mechanism that allocates a portion of the initial production cost to each of the two stages of the product life cycle should be used. We also conclude that cost allocation should be implemented as a fixed cost allocation, where charges to the remanufacturing division should be determined independently of the actual quantity of units remanufactured.     

A course for clinical trial personnel in clinical study designs, randomization, allocation schedules, and interactive response systems

This continuing education course for professionals involved in all areas of clinical trials integrates concepts related to the role of randomization in the scientific process. The course includes two interactive lecture and discussion sections and a workshop practicum. The first interactive lecture introduces basic clinical trial issues and statistical principles such as bias, blinding, randomization, control groups, and the importance of formulating clear and discriminating clinical and statistical hypotheses. It then focuses on the most commonly used clinical study designs and the corresponding patient randomization schemes. The second interactive lecture focuses on the implementation of randomization of patients and drug supply through allocation and component ID schedules. The workshop practicum, conducted in small groups, enables students to apply the lecture concepts to real clinical studies. Flexibility was built into the workshop practicum materials to allow the course content to be customized to specific audiences, and the interactive lecture sessions can be stretched to cover more advanced topics according to class interest and time availability.

An adaptive allocation sampling design for which the conventional stratified estimator is an appropriate estimator

Adaptive allocations in stratified sampling design are suitable for studying Biological and Environmental populations. Biologists tend to use the conventional stratified estimator for an adaptive allocation sampling design in spite of its adaptive nature. In this paper, we have introduced an adaptive allocation sampling design for which the conventional stratified estimator has some desired statistical properties. We conduct a simulation study on a real population. The results show that the conventional stratified estimator for the introduced adaptive allocation sampling design is more efficient than other available estimators.     

基于项目治理的BT模式选择分析——以城市轨道交通项目为例

项目治理理论认为项目控制权配置与风险分担的匹配性对项目建设绩效具有深远影响,然而现有工程项目交易方式的选择通常仅考虑项目管理层面因素,而忽略了项目治理层面因素的影响,这导致BT模式下工程项目交易效率较低,成为制约BT项目在我国城市轨道交通项目中推行的关键因素之一。本文引入项目治理理论,以BT项目契约中风险分担匹配项目控制权强弱为原则,构建出项目特点、项目管理及项目治理三维度的选择框架,并得出强BT、标准BT、弱BT三种模式。通过案例分析验证了选择框架的有效性,为城市轨道交通BT项目的创新和优化提供了依据。
