Decompositions of λ K v

In a series of 2 papers, Kang, Du and Tian solved the existence problem for G-decomposition of λ K _n when G is any simple graph with 6 vertices and 7 edges, except when G is the graph T=K ₄∪K ₂. Notice that a T-decomposition can be considered to be a Pairwise Balanced Design in which each block of size 4 has been matched to a block of size 2. In this paper we remove this exception for all λ≥2. The case when λ=1 is also addressed. This paper is written in honor of Frank Hwang on the occasion of his 65th birthday.     

Use of balanced bipartite weighing designs as chemical balance designs

This paper deals with the use of balanced bipartite weighing designs as chemical balance designs when there Is a restriction on the number of objects that can be placed on either pan..The variance of each estimated weight and the covarlance of each pair of estimated weights are worked out.The use of additional weighing when the design matrix is singular is discussed.     

On the maximum number of constraints for s-symbol balanced arrays of strength t

Several upper bounds on the maximum number of constraints for s-symbol balanced arrays of strength t are given. Some bounds derived here include the results obtained by Rafter and Seiden (1974), Chopra (1982, 1983) and Saha, Mukerjee and Kageyama (1983).

两种m重-四角链图的优美性

刘春峰等证明了A型m重—四角链图、B型m重—四角链图的k—优美性及序列性。文章给出了另一种优美标号(也是k—优美标号),且在此标号下证得了这两种m重—四角链图是交错图,且具有奇优美性及平衡性。     

毛泽东区域经济均衡发展思想的理论渊源及实践效果

毛泽东区域经济均衡发展思想源于马克思、恩格斯的均衡发展思想和政治上“公平”、“平等”的理念。在这一思想指导下,我国建立起独立的比较完整的工业体系和国民经济体系,改变了旧中国生产力布局的严重畸形状况。但是,由于过分强调均衡和公平,结果却造成资源的巨大浪费,扩大了区域间的差距。     

浅论企业财务管理目标与评价手段的发展

随着企业财务管理目标的变化,新的财务管理手段,平衡计分卡应运而生。平衡计分卡通过财务指标、顾客、学习和成长以及内部经营四个方面来指引经营者关注各方利益,并据此来评价经营者的业绩。

An application of the integrated AHP-PGP model for performance measurement of supply chain management

The performance measurement problem has gained great attention in business and operations management literature. The first objective of this study is to determine the required performance measures and to develop a model for performance evaluation, based on these selected measures using analytical hierarchy process (AHP) methodology. The second objective is to explain how an integrated AHP-PGP (pre-emptive goal programming) model can be used in performance measurement while optimising the overall performance. An integration of AHP and multi-objective PGP is used to consider both quantitative and qualitative performance measures in optimising the overall performance of the system. The integrated model is presented with a real-world application using source data provided by a survey conducted in India. Findings demonstrate that the integrated AHP-PGP model can be useful to all supply chain industries in their day-to-day performance measurement decisions.     

On the recovery of intra- and interblock information in n-ary designs

This note presents an extension of Q-method of analysis for binary designs given by Rao (1956) to n-ary balanced and partially balanced block designs. Here a linked n-ary block (LNB) design is defined as the dual of balanced n-ary (BN) design. Having a note on Yates’ (1939, 1940) method of P-analysis, we further extend the expressions for binary linked block (LB) designs given by Rao (1956) to linked n-ary block (LNB) designs which admit easy estimation of parameters for these type of all n-ary designs.
