A Method on the Item Investment Risk Interval Decision—making of Processing Panking Style

In this paper,on the bases of the defect of riskful type and indefinite type decisions,the concept of the type of item investment probability scheduling decision is given,and a linear programming model and its solution are made out .The feasibility of probability type item investment plan is studied by applying the quality of interval arithmetic.     

A Case of Energy and Ecology System Development and a New Approach to System Dynamics Modeling

1　IntroductionIn our previous subject concerned with the development of energy and ecology systemengineering[1 ] ,we have proposed SD rate variable fundamental in- tree modeling and,then,built the model of this system which totally included six in- trees with this newapproach.But the difficulty in locating all feedback loops is a barrier on the way of ourfurther research on the feedback structure and functions of the complex system.Therefore,a new algebraic method named after SD branch- vec…     

The Further Development and Application of Grey Forecasting Model

1　 IntroductionChen[2 ] has done the transformation for original sequence { x(0 ) ( k) } by logarithmic func-tion,and then raised the smooth degree of discrete data,and hence expanded the appliedrange of grey forecasting models.Chen[2 ] compared the mean error in two cases for fore-casting output of TV′s in whole country,it is2 6 3.16 % before transformation,and it is2 3.6 % after transformation.The key raising the accuracy of grey forecasting is strengthening smooth grade of o-riginal sequ…     

Stability Analysis of Ranking Alternatives Based on Subjective and Objective Weight

1　 IntroductionWeights of criteria are used to assess the relative importance of the different criteria inmulticriteria analysis,which can influence ranking result more or less depending on themulticriteria decision-making( MCDM) method used.Determining the weights ofcriteria isusually a difficult task due to the decision-maker( DM) is not always clear about how toweightfor each criterion and is noteasy to understand thatthe change of weightinfluencesthe ranking results from qualitative mea…     

On Robust Stability of a Class of Uncertain Nonlinear Systems with Time—Varying Delay

The problem of robust stability of a class of uncertain nonlinear dynamical systems with time-delay is considered. Based on the assumption that the nominal system is stable, some sufficient conditions on robust stability of uncertain nonlinear dynamical systems with time-delay are derived. Some analytical methods and a type of Lyapunov functional are used to investigate such sufficient conditions. The results obtained in this paper are applicable to perturbed time-delay systems with unbounded time-varying delay. Some previous results are improved and a numerical example is given to demonstrate the validity of our results.     

A Measure of Learning Model Complexity by VC Dimension

1　IntroductionMeasure of model complexity is important for understanding how difficult a modelingproblem is and for optimizing model performance.Modeling,in all its varied forms,is theprocess of logical induction. A key question regarding induction can be stated as:whatmust one know a priori about an unknown functional dependency in order to estimate itonthe basis of observations?[1 ] . In the fields of engineering and computer science,thisquestion is known as the learning problem. Recently,…

Examplesof agency are universal,including employer-employees,lawyer-client,buyer-supplier,etc. Agency problem occurs in such arelationship because of informational asymmetry and goal conflictdue to differentattitudestoward risk between the principal and the agent. Adverse selection and moral hazard aretwo main types of agency problems.Agency theory focuse…     

A Stronger Uniform Consistency Chech and Adjustment Method

When vectors of a judgement matrix is arranged according to their weight in AHP,uniform consistency is always required and the check criterion is uniform check,In this paper,a stronger uniform consistency check is introduced which can obtain a exact and practical effect by making an adjust to any non-satisfying uniforming matrix.     

Electronic Project of Taxation Based on EC Under Single Nation

Because of no real location and its virtual interaction, the information flow, the cash flow and the logistic flow of EC (Electronic Commerce) are to be separated individually. So the traditional taxation based on those three flows is challenged. Under this condition, this paper researches how to levy taxes on EC through internet using internet technology. As to simplify the model. it relates under a single nation. But it will also give some measures about the international trades.
