In recent years, customer relationships have been recognized by enterprises as a critical factor to succeed in their business. Effective customer relationships can help enterprises to deliver more satisfying products/services to customers based on their needs, preferences, or past transactions. This model, however, emphasizes the use of customer information to benefit enterprises;in contrast customers receive less information from enterprises. To address this problem, many technologies have been proposed such as recommendation systems and intelligent agents that provide customers with more information for their possible needs. However, these technologies still have some shortcomings that initiate the discussion of a new Consumer Support Systems (CSS) paradigm. CSS is specifically structured to provide consumers with effective information from enterprises to support their decision making. In this paper, we present an object-oriented method for the development of CSS that supports enhanced customer relationships by emphasizing on effective information provision from enterprises to consumers. The method starts from the identification of CSS characteristics, through the recognition of a system architecture that supports the realization of these characteristics, and finally ends with the analysis and design of architectural class objects that collaborate to realize these characteristics. The method is use case driven with UML and Petri nets notations utilized and extended as its modeling tool. To illustrate this, the method is applied to an exemplified CSS for book publishing.

For the advances of Internet technologies in recent years, electronic commerce (EC) has gained many attentions as a major theme for enterprises to keep their competitiveness. Among all possible endeavors for the EC, research has shown that effective management of customer relationships by taking advantage of customer knowledges is a major source for keeping competitive differentiation. Therefore, it is commonly recognized as an important goal for an enterprise to promote its managerial effectiveness oil customer relationships through a prospective customer knowledge-based information system to achieve the so-called Customer-oriented EC. In this paper, we present an object-oriented method for the development of such a Customer Knowledge Management Information System (CKMIS). The method starts from the identification of customers and their desired knowledge-accessed behaviors, through the recognition of a system architecture that supports the identification and realization of these behaviors, and finally ends with the analysis and design of the architectural classes/objects that collaborate to identify and realize these behaviors. The method is use case driven with UML notations utilized and extended as its modeling tool. To illustrate, the method is applied to an exemplified CKMIS for a book publishing company.

Networked video courseware（NVC） provides a new research perspective for resource development in education technology field by combining education technology and film arts knowledge. Teachers often have difficulty in fulfilling complex courseware designs due to the lack of sufficient film arts knowledge. This paper presents a systematic object-oriented knowledge modeling which is developed and described in Unified Modeling Language（UML） for NVC design by summarizing and analyzing the expertise, cognitive rules and practices of various video elements applied in teaching. In the NVC system model,associations between entities and the NVC template structure is discussed in detail. A case study is given to demonstrate the procedure of how the NVC knowledge is expressed.

Enhancing the speed of finite element analysis in bridge structures not only improves the efficiency and quality of engineering design, but also plays a crucial role in bridge safety assessment, emergency management, and cost control. It is a key direction in the development of modern bridge engineering technology. The total stiffness half bandwidth of a bridge structure is a critical factor that affects the analysis speed, as its size directly influences the computational resources and time required to solve structural equations. This paper analyzes the characteristics of node arrangement when the total stiffness half bandwidth is minimized, and summarizes three principles. The AD algorithm is applied for node optimization ordering, and the algorithm is further optimized in light of the specific characteristics of bridge structures. An object-oriented bandwidth optimization program was developed using VC++. The correctness and reliability of the program were verified through comparative case studies, demonstrating that the method can optimize the half bandwidth value significantly, thereby reducing the computer memory usage and enhancing the computational analysis efficiency.

The rise of an integrated energy system requires the integration of multiple sources of energy to be embraced and transited over the power grid;that means the information and communication systems of traditional power systems will be extended, and their complexity will be increased. As the information and communication systems play a more important role in the infrastructure of the power system, a cyber-attack on them may have an impact on the power system and cause a serious threat to the integrated energy system. To analyze the threat to the complex and integrated system, some researchers provide some modeling methods to study the impact of cyber-attacks on the information and communication systems, such as the Attack Tree Model, Attack Graph Model, Petri Net Model for cyber-attack, Attack Description Language Model, State Transition Graph Model, etc. However, these modeling methods have some shortcomings. For example, they cannot describe the systematical cyber-attack and show the secure status during the cyber-attack;it is hard for them to analyze the larger and more complicated information and communication systems. To overcome the shortages, in this paper, a correlated matrix-based object-oriented model is proposed for cyber-attack modeling. With this model, the relationship between the attacker and victim can be directly built;the cyber-attack path and packets from the attacker can be tracked;and the status of the nodes and links can be shown during a cyber-attack. There are two steps to build the cyber-attack model. Firstly, the procedure and approach of the cyber-attack will be modeled by an object-oriented method;then, a correlated matrix model will be built for network topology, attack path, and attack procedure. By combining these two models, the whole cyber-attack model is created. Finally, to demonstrate the modeling method and its benefits, we use the MITM (Man-in-the-middle Attack) attack on measurement data of an AVC (Automation Voltage Control) sys

Spectral features in remote sensing images are extensively utilized to detect land cover changes. However, detection noise appearing in the changing maps due to the abundant spatial details in the high-resolution images makes it difficult to acquire an accurate interpretation result. In this paper, an object-oriented change detection approach is proposed which integrates spectral-spatial-saliency change information and fuzzy integral decision fusion for high-resolution remote sensing images with the purpose of eliminating the impact of detection noise. First, to reduce the influence of feature uncertainty, spectral feature change is generated by three independent methods, and spatial change information is obtained by spatial feature set construction and the optimal feature selection strategy. Secondly, the saliency change map of bi-temporal images is obtained with the co-saliency detection method to complement the insufficiency of image features. Then, the image objects are acquired by multi-scale segmentation based on the staking images. Finally, different pixel-level image change information and the segmentation result are fused using the fuzzy integral decision theory to determine the object change probability. Three high-resolution remote sensing image datasets and three comparative experiments were carried out to evaluate the performance of the proposed algorithm. Spectral-spatial-saliency change information was found to play a major role in the change detection of high-resolution remote sensing images, and the fuzzy integral decision strategy was found to effectively obtain reliable changed objects to improve the accuracy and robustness of change detection.

The generation of map units is a fundamental step for an appropriate assessment of landslide susceptibility. Recent studies have indicated that the terrain relief-based slope units perform better in homogeneity compared with the grid units. However, it is difficult at present to generate high-precision and high-matching slope units by traditional methods. The problem commonly concentrates in the plain areas without obvious terrain reliefs and the junction of sudden changes in terrain. In this paper, we propose a novel object-oriented segmentation method for generating homogeneous slope units. Herein, the multi-resolution segmentation algorithm in the image processing field is introduced, enabling the integration of terrain boundary conditions and image segmentation conditions in slope units. In order to illustrate the performances of the proposed method, Kitakyushu region in Japan is selected as a case study. The results show that the proposed method generates satisfactory slope units that satisfactorily reproduce the actual terrain relief, with the best within-unit and between-unit homogeneities compared with the previous methods, in particular at the plain areas. We also verify the effectiveness of the presented method through the sensitivity analysis using different resolutions of digital elevation models (DEMs) data of the region. It is reported that the presented approach is notably advanced in the requirements of the quality of DEM data, as the presented approach is less sensitive to DEM spatial resolution compared with other available methods.

Towards an integration of syntactic constructs and structural features for formalised object-oriented methods

An integration of formal syntactic constructs and object-oriented (OO) structural features is essential to a formalised OO method. It requires the formal semantics to be structured according to OO conventions. It also requires the OO features to be completely and consistently interpreted by format semantics. In this paper, a list of guidelines for achieving the integration is suggested. These guidelines are derived from a review of the existing formalised OO methods under two categories, OO style formal methods and formal style OO methods. The former possess a strong syntactic foundation but lack a complete coverage of OO features. The latter support all OO features but suffer from incomplete or inconsistent semantics. It is suggested that multiple schemas, on a common syntactic foundation with abstracted syntactic constructs that follow OO conventions, should be adopted.

The use of formal methods promises correctness, verifiability, robustness and reliability of operational software systems which have been developed so far. object-oriented methods enable easier development and maintenance of software application systems and promote the reuse of design and program code. Mapping formal specifications into an object-oriented application will therefore give a system that is not only correct and reliable, but easy to develop and enhance. In this paper, we show how specifications containing major decisions that financial managers typically make, can be expressed in the Z notation. These specifications are subsequently translated into pseudo object-oriented programs.
