Abstract: ntroducing the principle and method of object supply chain management into representative of service industry--tourism industry, this paper constructs the structural model of agritainment supply chain, analyzes its property and basic characteristics and its premise of quality control. Meanwhile, it puts forward the main strategies of improving service quality control of agritainment supply chain.

Abstract: This paper aims the ontology consistency to detect and identify potential conflicts and contradictions in the BIM design process, to improve the efficiency of the coordination and communication between engineers in departments. The information of building design such as concepts, nature, requirements, restrictions, etc., can be standardized by the ontology using a computer language, basing on which, consistency is detected. This paper describes the process that conflicts or contradictions are identified in the BIM design and modified to restore the process.

Abstract: Ground source heat pump technology is a new type technology of superficially geothermal utilization. By taking Chinese-Canadian cooperation in the energy-saving low-carbon environmental demonstration housing project for example, this paper is to introduce the low-ground heat used in the timber structure. Through analysis of the energy consumption on the integration technology for wooden structure and ground source heat pump, and compared with conventional energy on energy consumption, validated applying renewable energy sources on modern wooden structure will produce significant benefits on economic and environmental, which possesses significant role in promoting that creating a resource-saving and environment-friendly society.

Abstract: To the distribution status of agricultural products, this paper proposes a multiple-type vehicles refrigerated distribution route optimization model with soft time windows, innovatively considering that different type vehicles have different marginal and travel costs, and applies genetic algorithm to solve it. Finally, this paper uses an example to check the model, and proves that the model is feasible and effective.

Abstract: Foundation Engineering is a professional and basic course which must be learnt by the students in the majors relating to Civil Engineering and Architecture. The existing problems in teaching process is analyzed combined with our teaching practice, the teaching of Foundation Engineering should choose appropriate and excellent teaching materials, and strengthen contents of practical training to give great impetus on the innovation of teaching process.

Abstract: A dynamic approach is taken in this study to assess the efficiency of the various functions of the Xiaolangdi multipurpose project using the emergy evaluation method. These functions include flood control, ice jam prevention, sediment reduction, water supply and power generation. Through simulation modeling, both emergy inflows and outflows can be continuously tracked and the variations and uncertainties properly measured for different stages in the operation of the Xiaolangdi multipurpose project on an annual basis. Dynamic emergy analysis provides an alternative way to evaluate the efficiency of a multipurpose hydropower project.

Abstract: As the number of calling ships in container terminals rises, waterways in some harbors have become the major constraint to the overall performance of the ports service. By constructing anchorages, the congestion that happens frequently in harbor can be effectively eased, thus the traffic capacity is greatly enhanced. The purpose of this paper is to study the impact of anchorage number on waterway traffic capacity and provide theoretical foundation when deciding the anchorage scale. A simulation method with consideration of anchorages is adopted to analyze the vessels entering and departing process in coastal container terminal. Results show that waterway traffic capacity and anchorage number are polynomial correlated, waterway traffic capacity increases with the growth of anchorage number and ceases when beyond a certain level. It will be of great help to serve the planning and constructing ports and terminals.

Abstract: In the environment of the lowest price winning the bid, competition among the hydroelectricity construction enterprises has become increasingly fierce. For the sustainable development, they have to take low profit margins, even at the cost price for the successful bid. So the cost management, as one part of reducing expenditure of the hydroelectricity construction enterprises, is important. According to the investigation of the current situation of the cost management of The Three Gorges Company Gezhouba Group Co., Ltd, this paper proposes the method establishing the cost analysis database and the concrete steps, intending to improve the efficiency of the cost accounting and analysis by means of the information technology, and win the bidding competition advantages for the hydroelectricity construction enterprises. Meanwhile, this paper hopes that the measure has some reference value for the same industry.
