Complex adaptive system (CAS) theory is used to analyze the e-commerce system and the concept of e-commerce transaction network is proposed. The e-commerce transaction network can be viewed as a complex network which is constructed by transaction behaviors between buyers and sellers. Then we give a formal definition of the e-commerce transaction network and establish a multi-agent model for e-commerce...
Applies TSP (Traveling Salesman Problem) and solving algorithm to hole swarm NC programming, it could optimize tool path, reduce cutting time. According to points coordinates, the distance between points could be computed, take the link lines and distance between points as factors, the TSP model could be established. Applies backtracking algorithm and genetic algorithm to solve this model, the shortest...
Monomer pump is an engine's key component in the Altogether track feed oil system. When engine running, the monoblock pump is under high temperature, high pressure and easy to wear condition. Facing coat of monoblock pump is essential to enhance the engine's lifetime by elevating its resistance to high temperature, wear and corrosion. In this paper, the sputtering power, sputtering time, total sputter...
The self-designed Abrasive Flow Machine and Clamp are introduced in this paper. The technology issues of abrasive flow medium selection and process parameters settings are discussed. We conducted the experiment on the small hole with diameter of 0.15 mm. Through the experiment, the best process parameters of the Abrasive Flow Machining of small hole are obtained.
A prototype system called APAVA to implement the decomposition process for generating the best feasible assembly plan is presented in this paper. The system structure of the decomposition process is discussed with its four maim modules: the feasibility testing module, the evaluation module, the selection module and the decomposition module. Then, an assembly example is presented as the application...
An automated structural optimization system named VCD (Vehicle Concept Design) is shown in the paper. The system is based on CAE technology and also merges some advanced technology such as template method, parametric technology and optimization technology. It can build parametric body geometry model and FEM mesh model rapidly and automatically. The body's stiffness and modal could be solved well and...
Website quality is crucial for acquiring user satisfaction and e-commerce website success. Based on TAM and information system success model, we analyze the effect of website quality on user satisfaction. Website quality includes three dimensions: system quality, information quality and service quality. These dimensions affect user satisfaction through perceived ease of use, perceived usefulness and...
