Optimal Policy and Simple Algorithm for a Deteriorated Multi-Item EOQ Problem  [PDF]
Bin Zhang, Xiayang Wang
American Journal of Operations Research (AJOR) , 2011, DOI: 10.4236/ajor.2011.12007
Abstract: This paper considers a deteriorated multi-item economic order quantity (EOQ) problem, which has been studied in literature, but the algorithms used in the literature are limited. In this paper, we explore the optimal policy of this inventory problem by analyzing the structural properties of the model, and introduce a simple algorithm for generating the optimal solution to this problem. Numerical results are reported to show effi-cacy of the proposed method.
Regional Economic Geography with Externalities, Congestion, and Fiscal Policies in a Small-Open Growth Economy  [PDF]
Wei-Bin Zhang
Journal of Geographic Information System (JGIS) , 2010, DOI: 10.4236/jgis.2010.24028
Abstract: This paper develops a two-regional growth model with amenity, capital accumulation and regional public goods with public goods and fiscal policies. The economy consists of two regions and each region consists of the industrial sector and public sector. The industrial sector provides goods in perfectly competitive markets. The public sector, which is financed by the regional government’s tax incomes, supplies regional public goods. The public goods affect both firms and households. We show how to find equilibrium values of the dynamic system and simulate model. Then, we carry out comparative statics analysis with regard to parameter changes in tax rates, congestion and amenity. Our comparative statics analysis provides some important insights. For instance, a main difference between the effects of increasing the two regions’ tax rates on the output is that as the technologically advanced region’s (the other region’s) tax rate on the industrial sector is increased, the national industrial output, national capital employed by the economy, and the national wealth are increased (reduced). In the region which increases the tax rate, the wage rate, consumption and wealth per capita, output per labor force, the population, and land rent are increased, and the corresponding variables in the other region are reduced.
National and Regional Economic Growth with Fiscal Policies: Congested Public Goods and Endogenous Labor Supply of a Small-Open Economy  [PDF]
Wei-Bin Zhang
Modern Economy (ME) , 2010, DOI: 10.4236/me.2010.13020
Abstract: The purpose of this study is to build a two-regional growth model with capital accumulation, endogenous time distribution between leisure and labor, and regional public goods with fiscal policies. We emphasize dynamic interactions among capital accumulation, externalities, supply of public good with different fiscal policies, congestion of public good, endogenous time, and economic geography. The economy consists of two regions and each region consists of the industrial sector and public sector. First, we develop the two-region growth model with public goods and fiscal policies. Second, we show how to find equilibrium values of the dynamic system. Then, we simulate model with specified parameter values. Finally, we carry out comparative statics analysis with regard to parameter changes in tax rates and congestion. Our comparative statics analysis provides some important insights. For instance, a main difference between the effects of increasing the two regions’ tax rates on the output is that as region 1’s (2’s) tax rate on the industrial sector is increased, the national industrial output, national capital employed by the economy, and the national wealth are increased (reduced).
Nonparametric Demand Forecasting with Right Censored Observations  [PDF]
Bin ZHANG, Zhongsheng HUA
Journal of Software Engineering and Applications (JSEA) , 2009, DOI: 10.4236/jsea.2009.24033
Abstract: In a newsvendor inventory system, demand observations often get right censored when there are lost sales and no backordering. Demands for newsvendor-type products are often forecasted from censored observations. The Kap-lan-Meier product limit estimator is the well-known nonparametric method to deal with censored data, but it is unde-fined beyond the largest observation if it is censored. To address this shortfall, some completion methods are suggested in the literature. In this paper, we propose two hypotheses to investigate estimation bias of the product limit estimator, and provide three modified completion methods based on the proposed hypotheses. The proposed hypotheses are veri-fied and the proposed completion methods are compared with current nonparametric completion methods by simulation studies. Simulation results show that biases of the proposed completion methods are significantly smaller than that of those in the literature.
Environmental Policy and Pollution Dynamics in an Economic Growth Model  [PDF]
Wei-Bin Zhang
Modern Economy (ME) , 2011, DOI: 10.4236/me.2011.24071
Abstract: The purpose of this paper is to study dynamic interactions among capital accumulation, environmental change and labor distribution. We try to synthesize the growth mechanism in the neoclassical growth theory and the environmental dynamics in traditional models of environmental economics within a comprehensive framework with an alternative approach to household behavior. We build a model which describes a dynamic interdependence among physical accumulation, environmental change and division of labor under perfect competition with environmental taxes on production, wealth income, wage income and consumption. We simulate the model to demonstrate existence of equilibrium points and motion of the dynamic system. The simulation demonstrates some dynamics which can be predicted neither by the neoclassical growth theory Solow model nor by the traditional economic models of environmental change.
Spatial Monetary Economic Growth with Housing and Residential Distribution over the Urban Area  [PDF]
Wei-Bin Zhang
Journal of Geographic Information System (JGIS) , 2011, DOI: 10.4236/jgis.2011.34034
Abstract: This study introduces space, transportation, and money into an economic growth model. Growth theory neglects the importance of transportation on economic growth and transportation economics fails to properly explain how changes in transportation conditions (such as technological improvement, infrastructure investment, and oil prices) affect long-term economic growth. By proposing a growth model with transportations, we try to explain effects of transportation on economic growth. Our model describes dynamic interactions among capital accumulation, travel time, housing, residential distribution, amenity, and endogenous time distribution among work, travel, and leisure. The study examines effects of inflation policy, transportation conditions, and other conditions on long-term economic growth and economic geography. The paper demonstrates a way to integrating some important models in the literature in economic growth theory, urban economics, and transportation research so that the significance of transportation systems upon economies can be properly analyzed.
The Pricing of Convertible Bonds with a Call Provision  [PDF]
Bin Zhang, Dianli Zhao
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.46117
Abstract: This paper deals with the pricing of convertible bond with call provision based on the traditional B-S formula. By applying the principle of no arbitrage, the partial differential equation for the bond is established with identified boundary conditions, which solution results in the closed form of the pricing formula.
China’s Situation of Paid Annual Leave and Its Influence on Tourism Consumer Behaviors: A Research Based on a National Survey  [PDF]
Yujing Zhang, Bin Liao
Chinese Studies (ChnStd) , 2017, DOI: 10.4236/chnstd.2017.64022
Abstract: This paper investigates implementation of Workers Paid Annual Leave Regulations, and also analyses whether and how this regulation affects tourism consumer behaviors. The author designs questionnaires and administers them to 5884 subjects distributed throughout 7 regions in China to collect primary objective data about the situation of paid vocation and tourists’ behaviors. Based on data analysis, this research concludes that the regulation has not been implemented successfully, that people have more paid days off, they have more leisure travel and higher satisfaction with travelling, and that people who work for state-owned enterprises and public institutions enjoy more paid days off than those migrant workers and employees of private enterprises. It is therefore recommended that the Central Government should take three effective measures to promote implementation of paid leave regulations.
Polymer-polymer adhesion with mobile promoters: Connector areal density dependence
Bin Zhang
AIP Advances , 2013, DOI: 10.1063/1.4775350
Abstract: The adhesion between two immiscible polymers stitched together via mobile promoters is studied with large scale molecular simulations employing a coarse-grained bead-spring model. An adhesion model is presented that enables both connector molecular slipping out viscously and bulk dissipation in two dissimilar glassy polymers, in which one is dense melt and another is loose. The contributions to the separation work from thermodynamics and chain suction are studied in dependence of the connector areal density, at constant temperature, and at fixed basic molecular parameters. It is shown that high connector coverage, but below saturation areal density, can enhance the adhesion toughness and interfacial strength. Bulk dissipation is not considerable with low connector areal density in mushroom regime, while becomes more evident in the loose block when the coverage density is increased up to overlapping brush regime. With increasing connector length, both bulk melts are enhanced by the segments of connector chains that penetrated in. The results provide insight into the structure evolution of adhesion interface coupled with promoter molecular, which are useful for future developments of continuum cohesive models for fracture of polymer- polymer interfaces.

Abstract: Objective: To study the therapeutic effect of Bushen Rougan Recipe (BSRGR) on hepatic fibrosis in rats. Methods: Forty male Wistar rats were randomly divided into normal control group (n=10), model group (n=15), and BSRGR-treated group (n=15). Rats in the model and BSRGR-treated groups were administered intraperitoneally with 0.5% dimethylnitrosamine (DMN),10 ml·kg-1·d-1 , successive 3 days per week for 4 weeks to induce hepatic fibrosis. Then rats in the above 2 groups were given normal saline and BSRGR (10 ml·kg-1·d-1, ig) for another 4 weeks, respectively. Rats in the 3 groups were all executed at the end of the 8th week. The serum total bilirubin (TBIL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (A) and globulin (G) were determined and the serum hyaluronic acid (HA), laminin (LN) and collagen Ⅳ (Ⅳ-C) were measured. Results: The rat model of liver fibrosis was successfully induced by DMN. It was found that the serum TBIL, AST and ALT and the liver fibrosis marks were declined in BSRGR-treated group as compared with those in the model group (P<0.01). The content of total serum protein and the A/G in BSRGR-treated group were both increased as compared with those in the model group (P<0.05). Conclusion: BSRGR can be used to treat hepatic fibrosis in rats.
