APPLICATION OF THE INDEPENDENCE AXIOM ON THE design OF object-oriented software USING THE AXIOMATIC design THEORY

JOURNAL OF INTEGRATED design & PROCESS SCIENCE 2006年第1期10卷 57-69页

Current software design methodologies and techniques enhance software quality features. However, it is difficult to evaluate if a software design solution is good enough without a theoretical foundation. The use of Axiomatic design, together with a traditional software development methodology, can improve decision-making during the design process. This work presents an approach for object-oriented software design that intends to maintain the quality of the design solution along the development process. The goal of this approach is to facilitate the use of the Axiomatic design together with Unified Modelling Language and object-oriented software development methodologies such as Unified Process. This design approach relates object-oriented software design concepts such as use cases, collaborations, classes, operations, and objects with functional requirements, design parameters, and the zigzagging process. This work presents a functional decomposition hierarchy, based on software design concepts, which can be applied together with software design methodologies. This work also presents a case study to illustrate the application of a design approach, based on Axiomatic design, on an object-oriented design of a real-time embedded software system. The case study evaluates alternative design solutions to illustrate the application of the Independence Axiom in order to maintain the quality of the design.

This paper addresses the problem of reliably multicasting Web resources across wireless local area networks (WLANs) in support of collaborative computing applications. An adaptive forward error correction (FEC) protocol is described, which adjusts the level of redundancy in the data stream in response to packet loss conditions. The proposed protocol is intended for use on a proxy server that supports mobile users on a WLAN. The software architecture of the proxy service and the operation of the adaptive FEC protocol are described. The performance of the protocol is evaluated using both experimentation on a mobile computing testbed as well as simulation. The results of the performance study show that the protocol can quickly accommodate worsening channel characteristics in order to reduce delay and increase throughput for reliable multicast channels.

The AdEPar (Advanced Educational Parallel) integrated simulation and implementation environment for Digital Signal Processing (DSP) has been designed and implemented to serve as a test-bed for various scheduling, simulation, and code generation problems as well as a real-time implementation tool for DSP algorithms that could be mapped onto the proposed parallel pipelined architecture. The integrated environment fully exploits all types of concurrency present in DSP algorithms and addresses practical issues such as processor and memory constraints, architecture features of DSP processors in the target architectures, debugging of parallel programs, and development of high-level programming environments. The AdEPar software DSP environment is based on object-oriented programming techniques. Because DSP computation objects and graphics objects of AdEPar are separated from each other carefully, the software system portability is guaranteed. This programming approach saves time and effort to develop an environment based on a graphical user interface.

This paper presents a prototype object-oriented intelligent disassembly sequence planner for maintenance. A novel disassembly representation scheme known as disassembly constraint graph (DCG) has been proposed and implemented as a prototype system in this work. Using the DCG, all the possible disassembly operations that are needed for the maintenance of certain components or subassemblies can be deduced. Subsequently, a sequence-based optimisation technique, genetic algorithms, is employed to generate near optimal disassembly sequence from all the feasible combination of these disassembly operations. Based on the DCG, an object-oriented intelligent disassembly sequence planner for maintenance has been developed. The prototype system comprises three modules each having a set of objects. Users are able to view the entire disassembly process in accordance to the near optimal sequence generated by the planner via a graphical user interface. Two case studies, which are used to illustrate the effectiveness of the planner, are presented. (C) 2005 Elsevier B.V. All rights reserved.

Using Java exceptions as programming constructs in artificial intelligence algorithms is presented. Exceptions are originally provided for erroneous case handling by the Java language specification. Although it has been advised not to use exceptions for purposes other than error handling, here we have shown that exceptions can be used in certain situations, to increase the expressiveness of the language. Secondly, the advantages of incremental program design using object oriented schemes are given. An agent architecture project is presented with the emphasis on the incremental development and reuse of previous modules. It is shown that complicated behaviour can be obtained by making design decisions which will let generalize the function of created modules, allowing them to be reused for future developments and possible improvements.

This paper presents the results of a systematic literature review, which aimed to identify metrics for the quality of software that are applied in the design stage. Fifteen papers from different electronic databases were selected to answer three questions. The analysis allowed us to provide an overview of the metrics used to design artifacts. These metrics will serve as the basis for generating models based on artificial intelligence techniques (Neuronal Networks, Regression, or some other), that help to estimate quality in the early stages of the software development process. It is concluded that most of the design metrics are object oriented. In addition, the design metrics are applied to class diagrams, package diagrams and sequence diagrams.

object-oriented design patterns are used to solve recurring problems in the design of object-oriented software. The success of existing design patterns encourages researchers and practitioners to propose new design patterns especially for solving recurring design problems in specific domains. Assessing the quality of the design patterns being developed is an important task for a design pattern developer to determine which parts of the patterns need improvement. This paper presents a hierarchical quality model for object-oriented design patterns under development. The model focuses on two quality attributes, i.e. Embedded Knowledge and Pattern Language quality, of the object-oriented design patterns. The model relates several properties of the design pattern descriptions, i.e. usefulness, completeness, consistency, and understandability, to the two quality attributes. Four quality metrics are proposed to quantitatively measure those properties of the design pattern descriptions. In an evaluation, we obtain a satisfactory result as the proposed quality assessment model can be used to complement other existing design pattern evaluation methods.

A METHOD FOR CONTRACT design AND DELEGATION IN object BEHAVIOR MODELING

引用

IEICE TRANSACTIONS ON INFORMATION AND SYSTEMS 1993年第6期E76D卷 646-655页

作者： SAKAI, H Chuo Univ Tokyo Japan

Behavior modeling of objects is critical in object-oriented design. In particular, it is essential to preserve integrity constraints on object behavior in application environments where objects of various classes dynamically interact with each other. In order to provide a stable design technique, a behavior model using the notion of the life cycle schema of a class is proposed. To model the aspect of behavioral abstraction of objects, the notion of schema refinement together with a diagrammatic representation technique is also defined. In this framework, a formalization of behavior constraints on objects which interact with each other is proposed together with its graphical representation. Verification rules of consistency of behavior constraints are also discussed. In order to perform certain functions, several partner objects of the same or different classes should collaborate establishing client-server relationships. The contract of a class is defined as a collection of responsibilities of a server class to a client class where each responsibility is specified in the form of the script. To achieve a high degree of systems integrity, a procedure to derive scripts from behavior constraints on collaborating partners is developed. It is also critical to evenly distribute responsibilities to partner objects. A delegation is placing a whole or a part of responsibilities of an object in charge of other objects. Based on the design principle 'delegation along the aggregation hierarchy,' a unified design approach to delegation that enables to reorganize scripts in constraints preserving way is proposed.

IFAC Proceedings Volumes 1998年第26期31卷 167-172页

作者： Salaheddin Ali University of Kassel Laboratory for Human-Machine Systems D-34109 Kassel Germany

A novel design technique for the construction of human-machine interfaces is presented. This technique strives after increased user orientation adapting humanmachine interfaces to the cognitive structures of human users. Different models of the human knowledge that are available in analogous or conceptual form have to be considered, both in the design of a graphical user display and in the design of the underlying information management system. Fuzzy logic is used for translating natural language procedures acquired from operators into objects in knowledge bases. Thus, technical systems can be considered and controlled from different viewpoints.

AUTOMATIC RECOMMENDATION OF design PATTERNS BASED ON PATTERNS' INTENT

The gang-of-four (GoF) patterns provide best practices and reusable solutions to recurrent problems in object-oriented software design. We propose an automatic approach for ranking and recommending GoF patterns. design-pattern vectors, representing the GoF patterns in terms of the problem types they address, are constructed based on the design pattern intent ontology (DPIO) developed by Kampffmeyer. An input design problem is represented as an input-problem vector, constructed by matching terms extracted from its description with constraints and concepts characterizing problem types in the DPIO. Patterns are ranked and recommended based on similarity scores computed between the design-pattern vectors and the input-problem vector. The proposed method was evaluated on a collection of 36 design problems. With appropriate parameter setting, the actual answers to 69.44% and 83.33% of the problems were recommended within the top-3 and top-5 ranks, respectively. With additional term correspondences for improvement of term matching, the results were increased to 75.00% and 88.89% for the top-3 and top-5 ranks, respectively. Compared to text-based pattern ranking using a vector space model, our proposed method yielded significantly better performance when they were evaluated on the same problem collection.
