Based on the dynamic evolution of game and the limited rationality, the question that why the policy for the game of central real estate and a real estate developers was no work was explored. Based on this discovery, it finds that the abolition of unreasonable fees and the introduction of a unified property tax cannot adjust to the price. The only key is to contain the transferring to the consumers, which makes housing prices return to normal levels. Finally, the suggestion that using lower price to release more funds for the expansion of domestic demand and restricting the sources of speculators' funding are gave to government to regulate and control real estate effectively.

Can ERP software bring users economic benefits during a company's operational management? This paper adopts revised value chain method to construct a set of indicators. Using listed companies that implement ERP as samples and the implementation year as the starting point, it compares the value of companies three years before the implementation of ERP and two years after implementation of ERP and testifies it. In order to guarantee the reliability of the conclusion, it uses statistical analysis on the single variable and the multi-variance to test the results. The results show that if the effect of the industry and size factors is left out of account, the IT(Inventory Turnover), FAT(Fixed Asset Turnover), SC (Sales Changes) of companies that implement ERP system are obviously higher than those have not implemented it; the economic benefits of ERP users are better than the non-users; all the economic indicators of ERP users do not show obvious performance change in the implementation year. In the first year of implementing ERP, SC (Sales Changes) and RRE (return on equity ratio) change obviously, showing that ERP brings some economic benefits to users; in the second year of implementing ERP, besides higher SC and FAT than non-users, only ART(Accounts Receivable Turnover) and APT(Accounts Payable Turnover) change obviously, showing ERP brings in changes in users' market and sales segment, but other indicators do not change obviously.

On the international expanding model choice, little attention had been paid to the MNEs from developing countries. Drawing on a sample of 279 overseas subsidiaries invested by Chinese MNEs, the paper examines the factors of influencing the choice between wholly owned subsidiary and joint venture. The binomial logistic regression results show that the host countries' risk, the resource-based industry and the model of establishment have significant positive impact on the preference of joint venture. As a special consideration, the Central Stated-owned Enterprises prefer to choose joint ventures also. Moreover, unlike the MNEs from developed countries, the Chinese MNEs with high R&D intensity are more likely to set up international joint ventures.

In this paper we established an inventory control model for deteriorating items under the circumstances of vendor-managed inventory. With the assumption that vendor integrates the small amount of order quantities from downstream enterprises into a large quantity so as to minimize relevant costs, we studied a quantity-based integrated dispatching and inventory policy for the vendor. Then, a Bi-level programming model is proposed and a Genetic Algorithm is designed to solve the model. At last, a numerical example is used to verify the effectiveness and feasibility of the model.

On the basis of the minimum principle of the total cost, using the structure of logistics network and Mixed-integer Non-linear programming, we propose a mathematical model, taking the uncertainty of demand and number of recall and return of goods, the dynamicity of closed-loop network, the environment of E-commerce, and the time value of currency into account. And then we use LINGO to solve the problem, in order to determine the number of constructing or expanding the facilities, and optimum flows of transportation between the various facilities. At the end of this paper, we prove the validity and feasibility of the model through a practical example.

Network society is a new social formation promoted by information technologies which mainly refer to computer and Internet technologies. It could be suitable to apply the fundamental principle of ecology to the research of network society as an ecosystem, named network social-ecological system. Network social-ecological system has intricate formation and structure and is in a constant change. This paper analyzes the process of network social-ecological system structure formation by Maximum Flow Principle (MFP). A model based on MFP and Self Organization Map (SOM) neural networks is proposed to simulate the changes in the number of global network users and Websites. This paper also tries to find the underlying dynamics of network social-ecological system formation.

In view of the low speed, the heavy load, reversing, the frequently brake, the intense impact characteristics of AOD furnace tilting system, The double closed-loop with feedforward is used. Position regulator and speed regulator use PID algorithm. And the speed loop is designed, based on vector control. This control system was simulated by MATLAB Simulink software. The simulation result showed: Adjustment time is 8s, the position steady-state error is 0, so it has achieved the demanded target of 0.12 radian static error fully.

The trade-off between service cost and service level had become a core problem in the field of inventory management. A multi-item multi-location inventory model was formed for service parts with waiting time constraints. In the inventory system, the continuous-review policy was used. The goal of the paper was to look for an optimal stock for each local warehouse under the target service which was presented by an aggregate mean waiting time constraints per local warehouse. Steps of the efficient heuristics were given at the end of this paper. The model is of great meaning to improve the service as well as to decrease the cost for service parts.

Agricultural product transporting and manufacturing enterprises must synthetically consider the biologic attributes of agricultural products and the parameters of logistics channels to select the optimized logistics scheme. According to the attributes of agricultural products, the main influence factors of agricultural product logistics channel selection are analyzed. Moreover, an extension decision model of agricultural product logistics channel selection is built, which is based on the theory of extension decision and variable weights theory. The extension model can dynamically reflect the importance degrees of influence factors and special demands of decision makers during the whole agricultural product logistics operation process, and it can educe the optimized logistics scheme.

To solve low efficiency of stator assembly in an electric motor manufacturer, the process of assembly and manufacture of stators was taken as the object of our study and detailed analysis was carried out on the sequence of coil assembly. It was found through operation analysis and 5W1H question-asking method that quite a few problems exist, such as out-of-balance of hands, unreasonable arrangement of tools and parts, non-standard operation, etc. in the process of operation. Plans for improvement have been proposed and standard methods of operation established by this paper on the four principles of ECRS (Eliminate, Combine, Rearrange and Simplify) and in combination with the principles of motion economy. Standard working hours have been worked out for coil assembly process by way of MOD (Modular Arrangement of Predetermined Time Standard) method on such basis.
