This paper studied the modeling and simulation of the public opinion propagation in the small-world network. The public opinion information propagation characteristics were firstly analyzed, and different states of the people in the propagation environment were proposed. Based on that, this paper constructed the public opinion propagation model based on the agent modeling method, and proposed the...
The scalability of the ability to provide and deploy network services is one of the major demands of the next generation network, and is also the main challenge of the development of the network service model technique. Through the comparison of several different network service models and the analysis of the key mechanisms of the next generation network, this paper proposes an HSM (hierarchical state...
Scrum has become the most popular agile methodology in recent years. It focuses on management and organization of software project, and doesn't provide descriptions about how everything is to be done on a project. This paper presents an approach of combining the Scrum methodology with the UML modeling methods, in which UML modeling technologies are mapped onto the scrum practices. This approach follows...
The purpose of this study is to explore educational methods for conceptual modeling for novices. In this research, the subjects are high school students and freshmen in university enrolled in various programs. Typical errors in class diagrams made by these types of novice learners are not easily detected. Therefore, we collected and analyzed some common errors, then developed appropriate teaching...
Cooperative Vehicle Infrastructure System is an important research area of ITS. Evaluation of CVIS aims to evaluate the technical feasibility, economic benefit and the social effects of CVIS. This paper puts forward a comprehensive evaluation method based on Analytic Hierarchy Process (AHP) and Grey Relational Analysis Process (GRAP). It selects parameters which can reflect the performance of traffic...
One of the most important phases in information system development is data modeling. In higher education and in professional environment, the basic data models are ER model, relational model and object oriented model, i.e. class diagram. Since conceptual modeling is crucial data modeling activity, special concern on methods for conceptual modeling is given in this paper. Case study shows that application...
In this paper, we describe research results arising from a technology transfer exercise on agent-oriented requirements engineering with an industry partner. We introduce two improvements to the state-of-the-art in agent-oriented requirements engineering, designed to mitigate two problems experienced by ourselves and our industry partner: (1) the lack of systematic methods for agent-oriented requirements...
Cyber-Physical Systems (CPSs), characterized by deeply integrating computing, communication and control, are large-sale, complex, embedded systems with hybrid characteristic. The uncertainty of discrete states and concurrency of continuous process, caused by hybrid interaction between computing and physical process, make it difficult to be fully described by the traditional hybrid model. In view of...
Software architecture design ability is quite important for a college student majored in the direction of software technology. In college education, students can be trained to elevate their software architecture design ability. In this paper, we introduce our practice in cultivating students' ability of software architecture design by means of laying solid theoretical foundation, building favorable...
When modeling requirements, software analysts have to choose the relevant modeling constructs among all those available. If they do not choose the right set, their model may lack some important information or their model may contain many superfluous details. In previous work, we proposed to capture the purpose of a model with a set of model operations such as queries or model transformations. Then,...
The Instructional System Design (ISD) is an incremental process that systematically follows the phases of analysis, design, development, implementation, and evaluation. ADDIE is a best defined a model falling under the ISD framework and is composed of above five steps. Reference to ADDIE model and Rational Unified Process(RUP) specification, as well as Unified Modeling Language (UML), and with the...
In Model Driven Engineering (MDE), models are first-class citizens, and model transformation is MDE's "heart and soul". Since model transformations are executed for a family of conforming models, their validity becomes a crucial issue. This paper proposes to explore the question of the formal verification of model transformation properties through a tri-dimensional approach: the transformation...
It is laborious and time consuming to build domain ontology, which models a specific domain and specifies the concepts in a particular subject. In this paper, a 5W1H-based conceptual modeling framework for domain ontology is proposed, which is used to analysis domain concepts and relations from six aspects including Who, When, Where, What, Why and How. The definition of domain ontology, domain concept...
A double inverted pendulum system is a complex, multi-variable, highly nonlinear, strong coupling, and absolute unstable system. At present, the researchers focus little attention on the timecost optimization of swing up the double inverted pendulum from its downward position to the inverted position. Through the rational dynamics analysis of the inverted pendulum system, the optimization model of...
Product design process is a complex system engineering. To improve the management efficiency of product design process, this paper, presents a new mode of product design process management from the perspective of modularization. Firstly, the related concepts and attributes of product design process module (DPM) are put forward. Then, the structure model of product design process based on DPM is established,...
This paper sets up a DSS for human resources management and designs several models for the system, which is based on the status of faculty management and the faculty information of college in China. In this system, models mainly include student enrollment projections, teacher demand projections, and teacher own quantity forecasting, that are designed by using of grey systems theory and other mathematical...
In order to establish the optimized model of administrative permit, the paper analysed the incidence relation of administrative permit with multi-business. The modeling method of multi-business incidence relation was proposed by using role network theory and relationship function matrix. An instance was showed to introduce the application of the method in multi-business administrative permit system...
This paper sets up a DSS for faculty management and designs a model base for the system, which is based on the status of faculty management and the faculty information of college. Models of the system, such as teacher demand projections, teacher own quantity forecasting, student enrollment projections, and teacher classification structure prediction is designed by using of grey systems, operations...
The objective of this work is to propose a membrane computing model for software requirement engineering activities during the inception phase of the software development. The bio-inspired approach is used in requirement engineering for the transformation of user requirements into system requirements using a probabilistic distributed computing model with abstraction coefficients, amalgamation factors...
Change propagation analysis of trustworthy requirements is one of the important activities of trustworthy software evolution. From the perspective of the dependency relations among various trustworthy attributes which are included in trustworthy requirements and between trustworthy requirements and functional requirements, a three-stage analysis framework of trustworthy requirements change propagation...
