In coal road transportation scheduling there are some problems such as the efficiency, loss, safety and so on, in order to solve these problems, this paper analyze the actual situation and the actual demand of coal mine, study the coal highway transportation integrated management system which is based on C/S+B/S architecture, integrate IC card technology, Web technology, GPS technology and other new...
In this paper, we introduce a natural generalization of Weighted Set Cover and Maximum Coverage, called Size-Constrained Weighted Set Cover. The input is a collection of n elements, a collection of weighted sets over the elements, a size constraint k, and a minimum coverage fraction ŝ; the output is a sub-collection of up to k sets whose union contains at least ŝn elements and whose sum of weights...
This paper develops a holistic framework to examine the changing business models in creative industries in the digital economy, using evidence gathered from two strands of empirical work. The research found that digital technologies have facilitated pervasive changes in business models in all sectors of the creative industries, but with only a few exceptions, the resultant new business models are...
In order to realize the rapid construction and dynamic reconfiguration of human-computer interface, a rapid developing model based on component assembly was proposed recurring to an assistant design tool developed self-owned, as well as the assembly models of domain component and interface components. In the rapid construction model, the scheduling component cooperated with configure file to achieve...
The functional requirements of multiple tenants are supported by a single instance in a SaaS System, but the differences between tenants make it difficult to unify in same business logic. Based on the construction of SOA and using BPEL to deploy different processes on application servers, a business process customization model for the application layer is proposed and the specific solution of process...
Among all the restraints of the development of e-commerce, the security problem of transaction has become the key element. Meanwhile all kinds of e-commerce security technologies have attracted more and more attention and study. In order to find better solutions of e-commerce security problems, such as anti-wiretapping, anti-juggling of the information, transaction denying, and the false order form...
Requirement traceability matrix (RTM) is an important static requirement tracing method which is still applied widely in software projects. But traditional RTM mainly support vertical traceability which is started from functional requirements to the other software products, such as design documents, source code and test cases, and usually leads to lower efficiency of defects modification and respondence...
In complex rule flow logic verification, simulation based testing approach is one feasible way which tries to go through all the feasible paths. As the baseline, the total number of feasible paths is usually desired to know although it is usually a huge number. The calculation algorithm of feasible paths in a rule flow is proposed in this paper. Using air cargo loading planning rule as an example,...
For a multiple-segment flight of passenger aircraft, the primary objective of commodity load planning is to improve the operational efficiency of the whole journey. Unfortunately the objective can not be measured due to the unavailability of down-line stations shipment information. Traditional optimization algorithm can not be directly applied. Rule based optimization approach is proposed in this...
We present an efficient graph based rule execution method which incorporate expert knowledge and statistical knowledge. How to use both the knowledge from expert experiences and the statistical information from business instances to improve the efficiency of rule execution is meaningful. We define a directed acyclic graph to control rule execution where each potential sequential rule execution corresponds...
Rule set is used in many rule engines as the rule model structure. Such kind of model is insufficient in describing some operation logic with explicit sequence. This paper aims to categorize the business rules from three dimensions including rule sequence, context object and condition fragility. And the impact of these characteristic to rule model, language and algorithm is discussed. A hybrid rule...
Rule flow is a directed graph with condition and action operator over business object's attributes. The results from the the rule flow is usually not linearly separable, which proposes great challenges to rule flow learning from sample results. This paper proposes to use multiple linear classifiers for rule flows whose condition is the linear combination of business object attributes. This is a two-step...
Natural language is used to represent human thoughts and human actions. Business rules described by natural language are very hard for machine to understand. In order to let machine know the business rules, parts of business process, we need to translate them into a language which machine can understand. Object constraint language is one of those languages. In this paper we present a statistical machine...
Web-delivered service is an emerging approach for IT service by leveraging the partnership and Web technology to reduce IT service cost and improve delivery efficiency. To make it more effective, business design is also very important besides technology innovation. This paper proposes a three-tier analytical framework to improve business design based on the centralized information from the platform...
For a multiple-segment flight of passenger aircraft, air cargo load planning is the trade-off between operation time, mishandling ratio, and load factor. A rule-based optimization approach is adopted by us to model the complex business logic. In the load planning, there are several atomic actions, which is relatively stable and linked together by rule flow. This paper discusses the optimization algorithms...
Due to the considerably big marketplace, enterprises seek to benefit from e-commerce in China. But up to now very few of them have been successful, because some successful business models and strategies in developed countries can not be applied in China. This study examines obstacles on e-commerce development in China and attempts to find out some solutions to overcome these barriers. The relevant...
