Technical Notes ：STUDIES ON THE VALUE OF SECONDARY MARKET TO THE SUPPLY CHAIN

This paper investigates the impact of a secondary market, where retailers can buy and sell excessinventories, on the supply chain. We develop a two-period model with a single manufacturer and tworetailers. At the beginning of the first period the retailers order and receive products from themanufacturer, but at the beginning of the second period, they can trade surplus products betweenthemselves in the secondary market. We investigate the impact of the correlated dependence ofretailers' demand on both the quantity effect and the allocation effect under the secondary market.Lastly,we study potential strategies for the manufacturer to increase sales with the existence of thesecondary market.

FROM MANUFACTURING SCHEDULING TO SUPPLY CHAIN COORDINATION：THE CONTROL OF COMPLEXITY AND UNCERTAINTY

With time-based competition and rapid technology advancements, effective manufacturingscheduling and supply chain coordination are critical to quickly respond to changing marketconditions. These problems, however, are difficult in view of inherent complexity and variousuncertainties involved. Based on a series of results by the authors, decomposition and coordination byusing Lagrangian relaxation is identified in this paper as an effective way to control complexity anduncertainty.A manufacturing scheduling problem is first formulated within the job shop context withuncertain order arrivals, processing times, due dates, and part priorities as a separable optimizationproblem. A solution methodology that combines Lagrangian relaxation, stochastic dynamicprogramming, and heuristics is developed. Method improvements to effectively solve large problemsare also highlighted. To extend manufacturing scheduling within a factory to coordinate autonomicmembers across chains of suppliers, a decentralized supply chai

Subset threshold autoregression

We develop in this paper an efficient way to select the best subset threshold autoregressive model. The proposed method uses a stochastic search idea. Differing from most conventional approaches, our method does not require us to fix the delay or the threshold parameters in advance. By adopting the Markov chain Monte Carlo techniques, we can identify the best subset model from a very large of number of possible models, and at the same time estimate the unknown parameters. A simulation experiment shows that the method is very effective. In its application to the US unemployment rate, the stochastic search method successfully selects lag one as the time delay and five best models from more than 4000 choices.

20#管线钢在役焊接HAZ的组织与性能研究

在役焊接过程中，管内流动介质的快速冷却，易使接头出现氢致裂纹。对20^#管线钢在不同冷却条件和不同焊接线能量下的HAZ的组织性能进行了模拟研究。结果表明，在流动水冷却下，HAZ出现较多的贝氏体、马氏体和MA组元等不平衡组织，使得HAZ的硬度高达330HvN5，性能最差。采用大的线能量焊接，形成较多的上贝氏体和粒状贝氏体组织，对改善接头性能有利。因此，在避免烧穿的前提下增大焊接线能量或减小管内介质的冷却能力，减少高硬度不平衡相的形成，可以降低HAZ氢致开裂敏感性。     

高校后勤社会化改革的法律风险及其防范

由于高校后勤社会化模式的混乱,使后勤社会化改革中出现了一系列法律风险。为防范该风险,应在全国实行统一的后勤社会化改革模式——专门机构负责模式,即采用“外部采办”的方式,并通过相关的制度设计来规范高校后勤服务实体的运作。     

发挥高校后勤服务教育功能提升学生就业创业能力

在高校后勤社会化改革向纵深推进的过程中，应该更加理性地思考、分析高校后勤社会化的地位和功能。我们应从更广远的视野来认识高校后勤社会化的教育属性，力求以市场经济为纽带，把后勤社会化与学生就业、创业能力的培养结合起来，以充分发挥后勤社会化的育人功能。
