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     

工矿企业能量平衡通用模式的研究

提出了适用于工矿企业能量平衡的一种通用模式，将与ＧＢ３４８４－８３《企业能量平衡通则》再增加“一表两图”──“企业能量平衡表”、“企业能源网络图”和“企业能流图”的效果相一致，能更加科学、合理地反映企业能量平衡的结果。     

镁改型蛭石对铵离子的交换性能

对经人工改型所得的镁型蛭石进行了铵离子交换性能的研究．在不同pH值下测定了镁型蛭石对NHr的全交换容量，在不同温度下测定了样品的平衡等温线．结果表明，镁型蛭石对NH4^ 的交换总量随pH值的变化而波动，在pH值为7时其交换总量为59．32mmol／100g，其选择性随温度的降低而升高，这为蛭石作为一种新型填料提供了一定的理论依据。
