This paper firstly describes the definitions of stock and virtual organization (VO), then gradually show the importance of inventory management under the environment of VO. Although the classical model of Economic Order Quantity (EOQ) is widely used in the inventory management of traditional enterprises, it's not applicable to VO. As an integrated system composed of two or more traditional enterprises,...
In order to optimize the capacity of farmers' income persistently increasing, in this paper we analyze 8 factors affecting farmers' income increasing using PLS model based on the statistical data of Heilongjiang reclamation from 2000 to 2008. The study shows that wage incomes, agricultural subsidy and tax reducing still account for a great proportion of farmers' net incomes, but the level of agricultural...
At first, based on the thought over properly and the modern market competition, the flexible development of Circular Economy has been advocated as a new model of economy development. This development model can solve the externality problems better which have not been solved under traditional model. Then, in this paper, the"3+3"model of the flexible development of Circular Economy has been...
By constructing the exponential delay cost function, we formulate the consumer decision model based on the threshold strategies in dual-mechanism, and prove that there exists a unique symmetric Nash equilibrium in which the high-valuation consumers use a threshold policy to choose between the two selling channels. Then we extend our model under general delay cost function, and find that consumers...
This paper divided China into three sub-regions to study the corn production. After built yield and acreage model of corn with Nerlove Model, this paper analyzed the factors which affected corn's yield and planting areas in different sub-regions. At the last section, calculated the elasticities of yield and planting area in sub-regions for the short run and the long run. The result indicates that...
On the basis of hypothesis of limited time and multistage order, the order strategy was brought forward for the changing charge, and the multistage stock model with deteriorating lose were constituted for the Single Short Life Products (SSLPs) and Multiple Short Life Products (MSLPs) under different order strategies. In addition, that the combined order mode was better than the other order modes for...
The reform of electricity price is the core of electricity deregulation, and reasonable price should be an organic unity of price level and price structure. The examination of the effects of peak-load price under different price cap forms dawns on us that the price cap regulation has the effects of cost-recovery. Comparing with absolute price cap regulation, the relative price cap regulation is more...
From the viewpoint of flexible strategy and network innovative height, industrial clusters possessed significant regional characteristics and strategic competition become the research objects in the paper. Three networks such as dynamic distribution networks, agile trading network and open social relation network and so on successfully operate in regional economy environment of liaoning province....
Empirical Study on the relation between direct financing in the capital market and economical development in China was carried out with co-integration test and error correction model based on the annual data from 1981 to 2009. The results indicated that there is long/short run and stationary positive relation between direct financing and gross domestic product (GDP). It's found that direct financing...
Environmental carrying capacity is one of the most critical indicators in tourism management of scenic areas, such as forest parks. In this study, the overall tourism environmental capacity (TEC) of Jiufeng National Forest Park was calculated by using the logistic model. Recommendations for the park management were provided based on the results. Further more, some ideas for integrating overall TEC...
In this paper, an effective scheme is proposed for coding n-node Boolean networks. The scheme can uniquely designate a distinguished integer in the range from 0 to (2n×2n -1) for any a given Boolean network. At the same time, a linearized matrix is obtained for any a given Boolean network. The linearized matrix depends only on the information hidden in the logical table of the given network. By analyzing...
In the paper, we derive a delayed reaction-diffusion equations, which describes a multi-species Predator-prey system. By coupling the perturbation approach with the method of upper and lower solutions, we prove that the traveling wave fronts exist and appear monotone, which connect the zero solution with the positive steady state. Finally, we draw a conclusion to point out that the existence of traveling...
The paper has made the analysis for the unbalanced international trade at the later stage of the global financial crisis. Through the analysis of the reason for the unbalanced international trade, the paper has argued that the broken symmetric conditions have resulted in the international trade unbalance. Based on it, the paper has made the chaos analysis of the unbalanced international trade at the...
This paper proposes a new mathematical method to solve min-max predictive controller for a class of constrained linear Multi Input Multi Output (MIMO) systems. A parametric uncertainty state space model is adopted to describe the dynamic behavior of the real process. Since the resulting optimization problem is non convex, a deterministic global optimization technique is adopted to solve it which is...
This paper used the finite element method to analyze the cerebrovascular bifurcation. By comparison, we constructed two intracranial artery bifurcation vessel models with different angles, and considered different model how to influence vascular blood flow based on the basic principles of hemodynamics. Through experiment, we mainly computed the value of blood velocity and wall pressure, and compared...
Distinctiveness of users in biometric authentication can be limited when multiple samples of a user's biometric information differ due to intra-class variability in the acquisition, thus resulting in random correspondence between users. Most of the currently known methods based on error correcting codes, fuzzy vault have been proposed for protecting biometric data against the intra-class variability...
Performance of biometrics in human authentication can be limited when multiple samples of a user's biometric information differ due to intra-class variability in acquisition, storage or transmission of biometrics. Thus, random correspondence results between users. We formulate probability of random correspondence (PRC) by developing an information model of biometrics features as a noisy source. The...
A new formulation facilitating the determination of the autocorrelation lags, and consequently the autocorrelation matrix, of an autoregressive moving average signal of arbitrary order (ARMA(p, q)) is presented. The main features of our formulation, stated as a set of linear equations to be solved, are 1) its conceptual simplicity 2) its reliance only on primary parameters of the ARMA(p, q) model,...
The paper presents the design of a discrete linear quadratic gaussian (DLQG) compensator for SSR damping which includes a full order Kalman filter to estimate all the states of the system and a full state feedback regulator. The controller is tested on IEEE First Benchmark model for SSR studies. A discrete linear-time invariant (LTI) model of a thyristor-controlled series capacitor (TCSC) in the synchronously...
A general model of oil consumption is investigated in this study. This model should be applicable to different countries even with different characteristics. Conventional model that works very well for Malaysia is tested with seven developing Asian countries: China, India, Indonesia, Malaysia, Pakistan, Philippines, and Thailand. The results have shown that this model can not produce a good fit to...
