Study on DSM-based task planning of product cooperative development

The results of analyzing the managerial characteristics and complexity of product cooperative development suggest that task planning is an important aspect for process management of product cooperative development and the method for planning tasks should be able to model the dependency between tasks and iterations during the development process. In this paper, a DSM-based method and its corresponding optimization algorithms are developed. At first the coupled task sets and uncoupled task sets are identified, and the tasks are then optimized by the corresponding algorithms. The optimal tasks plan will reduce the development time and cost. Considering the practical requirements in real world, a Multilayer DSM is proposed, and its information communication techniques between DSM and traversing principle are described in details.

MODELING METHOD OF 4D INFORMATION MODEL FOR COOPERATIVE DESIGN OF MECHANICAL PRODUCTS

The continuous developing features in the design of mechanical product and based on 3D entity model is aimed at, and the extension of the 4-dimensional model with the process of designing, the knowledge described model on the level of semantic understanding and summarizing the designing process and the way of discovering knowledge from multi-information model are studied. On the basis of designing the broad sensed collaborative system, through discussion of the relationship between the implicit knowledge of the users and the designing knowledge as well as commanding all the designing links, taking advantage of the way of concluding and deducting in the concept of the designers, the synthetic knowledge unit formed in the dynamic process from the conception design t9 the last design is schemed out, and the knowledge discovered principle in the dynamic designing process of the mechanical products and the key technology in its implementation under the milieu of network is brought forward.

Study on the "Going out" Strategy in Reform of the Supply Front for Agriculture

The three rural issues have been always valued by all circles. At present,the main conflict of agriculture in China has been changed from insufficient total amount to structural conflict. Thus,deeply promoting the reform of agricultural supply front has become a primary work in rural areas. It is required to follow the national grain security strategy based on domestic supply and moderate imports,to ensure production capacity. Besides,China should make full use of domestic and foreign markets and resources to protect the domestic agricultural consumption demand,which is favorable for resolving the current structural conflict and also favorable for sustainable agricultural development.

Belt and Road Initiative:Enhancing Regional Economic Cooperation and Improving Global Governance

SINCE President Xi Jinping first proposed the Belt and Road Initiative in 2013,more than 100 countries and international organizations have shown keen interest in the program.Around 50 countries have signed cooperative agreements（or MOU）,more than 20have carried out productivity cooperation,

Opportunities and Challenges of China-Middle East Countries’Production Capacity Cooperation

The Middle East is a region where China has more advantages in production capacity cooperation.China started early and has a good reputation in the area of engineering contracting,which has laid good foundations.At present,the Middle East countries are in an important stage of economic transformation.In order to accelerate industrialization,they have developed long-term economic development plan,which provides an important historical opportunity for Chinese enterprises to establish business there.The production capacity cooperation between China and the Middle East countries will utilize the complementary advantages and adhere to mutually beneficial and win-win spirit,and thus has been welcomed by the Middle East countries.At present,the two sides are carrying out fruitful cooperation in infrastructure,high technology and labor-intensive industries,and have achieved significant results.The production capacity cooperation between China and the Middle East countries are facing both opportunities and challenges.We should make good use of opportunities,prevent and resolve risks,and effectively do a good job in production capacity cooperation between China and the Middle East countries.

China's Rural Industrialization and Agricultural Mechanization

Rural industrialization provides nonfarm employment opportunities and financial support for farmers and may be a non-negligible cause of agricultural mechanization in China.However,there is a lack of empirical studies on this topic due to challenges in obtaining data and identifying causal relationships.In this paper,we use multiple data sources and construct an instrumental variable based on the number of handicraft production cooperatives in 1957 to test empirically the causal effect of rural industrialization on agricultural mechanization.The results show that rural industrialization contributes significantly and robustly to agricultural mechanization.A 10 percent increase in the average number of industrial enterprises per township was associated with a 1.05 percent increase in the agricultural machinery power per unit area of arable land.Both the demand effect and income effect played crucial roles in the interaction between these two phenomena.

China-Middle East Cooperation in the Field of Infrastructure under the Framework of the“Belt and Road”Initiative

Infrastructure is not only a priority of the“Belt and Road”Initiative,but also an important component of the productivity cooperation between China and Middle East.The Middle East was one of the regions that had been working with China in the early stage after China’s reform and opening up to the outside world,and since China was integrated into the world economic system and carried out international cooperation.China has a good foundation and experience in the cooperation with the Middle East in the field of infrastructure.Based on the analysis of basic problems of the Middle East infrastructure,this article sorts out the main mode of China’s cooperation with the Middle East in infrastructure,and points out the main problems in China’s expansion in the Middle East infrastructure market.According to the characteristics and future scale of infrastructure market in the Middle East countries,this articles puts forward some countermeasures and suggestions for future development of Chinese enterprises in the Middle East market in the field of infrastructure as well as the proposals to increase market share.
