在管理信息系统中单据设计的新方法

在分析PowerBuilder中用户对象的基本概念与特点基础上，提出了利用用户对象技术实现MIS(管理信息系统)中单据设计功能的方法，并给出了详细的实现过程。实际应用表明，该方法可使用户按企业的实际需要对单据的录入界面进行自由设计，无需修改软件即可满足不同用户的需求，适合各种管理信息系统的单据设计，具有通用性。     

Preliminary Contribution to the Quantification of HMF in Honey by Electrochemical Biosensor Chips

Several hydroximethylfurfural (HMF) microbiosensors, based on a microelectrode configuration built by photolithographic techniques, have been developed. Two different biosensors based on the aldehyde dehydrogenase (ALDH) enzyme coupling with NADH oxidase (NOD) or diaphorase (Diaph) are described. Experimental variables were optimized using experimental design methodology, by central composite designs, taking the intensity registered for a given HMF solution as response. Given the reproducibility (residual standard deviation (RSD), 7.20%), repeatability (RSD=3%) and limit of detection (LOD)=1.68×10^?4 mol dm^?3 (α=β=0.05 and a replicate) reached by the ALDH‐Diaph microbiosensor under the optimum conditions, the analysis of HMF in honey was successfully accomplished.     

A profit-maximizing supply chain network design model with demand choice flexibility

We present a profit-maximizing supply chain design model in which a company has flexibility in determining which customers to serve. The company may lose a customer to competition if the price it charges is too high. We show the problem formulation and solution algorithm, and discuss computational results.

Large set of P3‐decompositions

Let G=(V(G),E(G)) be a graph. A (n,G, λ)‐GD is a partition of the edges of λK_n into subgraphs (G‐blocks), each of which is isomorphic to G. The (n,G,λ)‐GD is named as graph design for G or G‐decomposition. The large set of (n,G,λ)‐GD is denoted by (n,G,λ)‐LGD. In this work, we obtain the existence spectrum of (n,P₃,λ)‐LGD. © 2002 Wiley Periodicals, Inc.
