In this paper, the structure of infeasible solutions to Job Shop Scheduling Problem (JSSP) is quantitatively analyzed, and a necessary and sufficient condition of the deadlock for JSSP is also given. For a simple JSSP with 2 machines and N jobs, a formula for calculating the infeasible solutions is proposed, which shows that the infeasible solution possesses the majority of search space and only those heuristic algorithms which do not produce infeasible solutions are valid.

＜正＞ The reformation of the economy system has led the functional department and status of the enterprises into a variable state. Under the condition of the market economy, the kernel of the enterprises’ functional department has diverted to that of marketing decision-making, which face to market and meet with the need of consumption. Assuredly, the kernel of marketing decision-making is to prognosticate the future market demand of the production of enterprises accurately, so that it can ensure and realize the maximum of the enterprises’ profit *** empirical research and the multi-regression technique, this paper analyzes the enterprises’ production demand forecast of the CMC （Global management Challenge, held every year globally） and changes most of uncontrollable factors of demand forecast to the controllable ones of the enterprises. The method we used to forecast demand by using the multi-regression technique is as follows;1. Look for the main factors which influence the demand of productions;2. Establish the regression model;3. Using the historical data, find the resolution of the correlative index and do the prominent test;4. Analyze and compare, regression, adjust parameter and optimize the regression model. Our method will make the forecast data closer to the actual prices of the future marketrequirement quantity in the production marketing decision-making of the enterprises and realize the optimizing combination and the working object with the minimum of the cost and the maximum of the profit. And it can ensure the realization of the equity maximum of the enterprises and increase the lifecycle of the production.

＜正＞ The integration of international economy dominated with the financial market leads to fierce competition. This requires firms implement modern corporate financial mechanism. From the view of the current situation of financial management in china, we demonstrates the differences in financial management between Chinese enterprises and international companies by describing detailed case studies of typical large enterprises in *** transform the enterprise management mechanism, the enterprise financial mechanism must be transformed accordingly. The basic ideas for its transformation and establishment include:1. Changing the managerial ideology, that is, completing the ideological change from the management of goods to the management of capital;2. Establishing a scientific organizational mechanism for financial management;3. Establishing a mechanism for scientific management, supervision and assessment;4. Training high-level financial management personnel with modern management knowledge;5. Dividing promotion center, distribution center, cost center and profit center in financial *** view of the above basic ideas and basic principles for the transformation and establishment of enterprise financial mechanism, we found that;the basic content that needs transformation in the theory of china’s traditional enterprise financial mechanism should include the content of finance main body, the content of financial objectives, the content of financial organizational structure and the content of environment for financial management. At the same time the following theories should be introduced, particularly the theories of capital time value, of risk in finance management and risk management, of the capital cost and capital structure, so as to establish a basic theoretical framework for the modern enterprise financial *** on the analyses, this paper discusses the impacts of economic globalization to Chinese large enterprises and their financial management

1950年代初期,由东北行政学院司法系演化而来的东北人民大学法律系正经历着从干部培训班向综合型大学法律系转型的过程。无论教员个人的教育背景如何,都毫无例外地被纳入到学习苏联和保证教学内容政治正确的轨道中。"苏化"的具体做法包括模仿苏联,建立教研组、教研室制度,翻译苏联的法学教材,模仿其教学内容和教学方法。这就使苏联法学在中国渗入到各个环节。政治化表现为无论是教员还是学生都要参加大量的政治学习。

物权归属于谁并非一个无关紧要的问题。物权法规定的权利主体应当是面目清晰、可以计数的,并且不同权利人的权利应有明显界分。因此,彻底放弃在农村实行的"个人-家庭"双重主体标准,对实际支撑《宪法》所说的"劳动群众集体所有制"的村或乡(镇)的"集体经济组织"、村委会、村民小组、村内各个农村集体经济组织甚至乡(镇)政府做出正面规定,将"所有制"概念还原为"财产",实乃让物权立法回归为一部集中关注财产权利的,更单纯的、具有可操作性的法律的必由之路。

From the theoretical point of view, the states of manufacturing resources can be monitored and assessed through the amount of infor- mation needed to describe their technological structure and operational state. The amount of information needed to describe cellular manufacturing systems is investigated by two measures: the structural entropy and the operational entropy. Based on the Shannon entropy, the models of the structural entropy and the operational entropy of cellular manufacturing systems are developed, and the cog- nizance of the states of manufacturing resources is also illustrated. Scheduling is introduced to measure the entropy models of cellular manufacturing systems, and the feasible concepts of maximum schedule horizon and schedule adherence are advanced to quantitatively evaluate the effectiveness of schedules. Finally, an example is used to demonstrate the validity of the proposed methodology.

The technical roadmap and policies for CO2 mitigation suitable for china are a common center of attention in the fields of energy, environment, and management science in the country. Emphasizing interaction between technical research and policy research, this work discovers the potential breakthrough in the integrated field. The technical difficulties of recovering CO2 are pointed out, the mechanism of combining CO2 recovery with energy conversion is investigated, and the basic principle for integrating an environmental-friendly energy system is discussed. Moreover, the formulation of a new energy system that can recover CO2 with very low or even zero energy penalty is proposed, while the assessment methodology and model system for the technical roadmap of CO2 emission control are developed. Finally, a new technical roadmap constructing an energy network suitable for china is proposed, which may provide a new way for the development of sustainable energy and environment technologies.
