TSP (Traveling Salesman Problem) is the generalization and simplification of a variety of complex issues that arise in many areas, which is easy to describe but difficult to solve as an NP complete problem. Based on the TSP problem, we allow more than one vehicles to distribute goods in the transportation network, and each node in the network can be serviced by more than one vehicles. We build a more...
Project construction is a kind of highly risk industry. Risk is inherent in construction projects of all types and sizes. It has many causes and its effects manifest themselves in various forms. Most recognizable are impacts on the schedule, where they reduce float, and its flexibility to absorb delays and thus mitigate risk. Regardless of the nature of risk, it is measurable by its effect. The project...
Collecting-Dispatching system connecting the port and its hinterland requires all the resources collaborated reasonably. Freight forwarders' business in the Collecting-Dispatching system includes booking, scheduling transport mode and carrier, consulting with port operation and so on. In short, freight forwarders are meant to provide “one-stop” service for the owners. Forwarders should make scientific...
Vehicle detection and traffic flow parameters extraction from high resolution imagery have been popular research topics in recent years. Object-based image analysis, with the aid of commercial eCognition® software, has become a widely implemented method for vehicle detection and identification. In the process, the determination of optimal segmentation parameters is of crucial importance for the accuracy...

The database audit is one of important mean to protect the security of database. In the life insurance industry, because of it master a large amount of important customer-related information, it is necessary to database audit. With the increasing of audit records and the requirement of database audit, simple means based audit log data unable to take full advantage of its intrinsic value. Thus, this...
Dividends distribution of Chinese listed companies is different from other countries, where exits a particular phenomenon called highly send and transfer stocks especially in growth enterprise (hereinafter referred to with GEM). This paper empirically investigates the influencing factors of highly send and transfer stocks, and tests hypothesizes of highly send and transfer stocks. Different from current...
Risk, existing in various forms during the process of Colleges and Universities' Sci-tech Innovation (CUSTI): the project application period, the project development period and the achievement transformation period, is a vital reason that restricts the innovation at colleges and universities. Fuzzy evaluation model is constructed and empirically operated based on the characteristics of CUSTI's achievement...
The State Council proposed to develop the strategic emerging industries and give them some support in terms of policy in 2010. Under the policy context, this paper selected the new energy industry as the research object. Based on the panel data of the new energy industry from 2010 to 2014, we found that government subsidies had a weak positive correlation with the capital structure but a significantly...
Unlike most of the empirical analysis, this paper applies netlogo multi agent simulation software to explore the complex and dynamic relationship between team commitment, knowledge sharing and performance. Combined with related parametric evolution curves, concluding: teams with higher level of commitment have bigger scale and higher total output, average level of output and level of effort decrease...

This paper studies the order promising problems that frequently arise in EMS-OEM scenario with multiple demand classes. Demands and replenishment of inventory in different periods are assumed to be random variables and independent of one another. An order promising system is designed to maximize the expected net profit over the planning horizon by determining the fraction of the demand that is likely...
