Information Assurance and Corporate Strategy: A Delphi Study of Choices,Challenges, and Developments for the Future

In this article, we identified processes associated with strengthening the alignment between information assurance, information systems and corporate strategies so that organizations could more effectively address legal and regulatory challenges. Our results are based on data gathered from 43 preliminary interviews and a subsequent Delphi exercise. The Delphi panel rated these processes in terms of desirability and feasibility. After three rounds a consensus of opinion was achieved. The results of the Delphi together with some practical implications are presented.     

New doctors ranking system based on VIKOR method

Nowadays, we can use different websites that help us make decisions about various aspects of our lives. However, privacy protection prevents websites from providing personalised guidelines to users. We propose a novel doctor‐ranking system (DRS) based on multi‐criteria group decision‐making (MCGDM) method to address the problems of privacy protection. The following aspects differentiate our proposed DRS model from previous works: (a) textual information reviews are used to identify user preferences and complementary criteria, (b) criteria weights are determined by term frequency inverse document frequency (TF‐IDF) instead of Delphi method or expert opinion, (c) intuitionistic fuzzy sets (IFSs) are used to replace sentiment analysis to express subjective user criteria, and (d) VIsekriterijumsko KOmpromisno Rangiranjie (VIKOR) method for MCGDM with IFSs is used to solve the doctor‐ranking problem. We apply our proposed model to datasets from Haodf.com to compare the performance of our method with that of sentiment analysis and technique for order performance by similarity to ideal solution (TOPSIS) methods. The experimental results show that our method provides accurate ranking and increases the reliability of DRS.     

Soft systems methodology to information systems: a Wittgensteinian approach

Abstract. A logical foundation for information system design requires a theory of meaning. Ideational theories attach meaning to the ideas in the private world of a conscious subject. By contrast Wittgenstein held that language and meaning were primarily public and that a private, purely subjective, language was impossible. The iterative debate among stake-holders that takes place in the practice of soft systems methodology (SSM) can be understood as a Wittgensteinian language game in which meaning is created not just discovered. The conceptual models used in SSM can be developed into logico-linguistic models which express stipulative definitions. These definitions can be taken as a logical basis for information system design.

基于设计模型的信息系统自动测试方法

针对当前自动测试领域存在的问题,提出了一种基于设计模型的自动测试方法（Model Based Automated TestIng System,MATIS）。该方法利用用户界面自动生成方法,把设计模型中的类属性定义和实现中的控件属性组织在一起,构建描述界面的逻辑对照表,辅助测试脚本引擎执行自动测试脚本。借助设计模型中扩展的类定义,MATIS方法可以自动生成测试用例和测试数据。MATIS方法是一个较轻量级的方法,更贴近于实际的软件开发过程,可以有效地降低自动测试成本。     

Novelties Within the Framework for Information System Due Diligence

The information system (IS) field lacks a scientifically based analytical tool for rapid delivery of IS due diligence. In 2013, a framework for IS due diligence (FISDD) was published. The work on this framework was continued with proceeding development and evaluation. One of the most important objectives of today’s business is making savings concerning various resources. The main novelty of the upgraded framework is the replacement of some of the manually conducted questionnaires with web-based questionnaires. This novelty reduces the total time required for on-site ISDD activities by 35–50%, as has been the result of several real cases. The results demonstrate and confirm the usefulness of upgrading FISDD, which increases its efficiency in DD processes, which is the main contribution of this article.

Smart card embedded information systems: a methodology for privacy oriented architectural design

The design of very small databases for smart cards and for portable embedded systems is deeply constrained by the peculiar features of the physical medium. Privacy concerns are relevant due to the fact that personal information may be stored on the card (e.g. medical records). We propose a joint approach to the logical and physical database design phases supporting the required security levels, on the basis that all information is stored on the Flash-EEPROM storage medium, managed as a file system by the smart card operating system.     

An integrated framework for mechatronics based product development in a fuzzy environment

New product development (NPD) is a term used to describe the complete process of bringing a new concept to a state of market readiness. Mechatronics based product requires a multidisciplinary approach for its modeling, design, development and implementation. An integrated and concurrent approach focusing on integrating the mechanical structure with basic three components namely sensors, controllers and actuators is required. This paper aims at developing a framework for a new Mechatronics product development. For conceptual design of Mechatronics system, various tools like Fuzzy Delphi Method (FDM), Fuzzy Interpretive Structural Modeling (FISM), Fuzzy Analytical Network Process (FANP) and Fuzzy Quality Function Deployment (FQFD) are used. Based on the prioritized design requirements, the functional specifications of the required components are developed. Then, Computer Aided Design and control system software are used to develop the detailed system design. Then, a prototype model is developed based on the integration of mechanical system with Sensor, Controller and Electrical units. Performance of the prototype model is monitored and Fuzzy failure mode and effect analysis (FMEA) is then used to rank the potential failures. Based on the results of fuzzy FMEA, the developed model is redesigned. The proposed framework is illustrated with a case study related to developing automatic power loom reed cleaning machine.     

The application of SSADM to modelling the logical structure of proteins.

A logical design that describes the overall structure of proteins, together with a more detailed design describing secondary and some supersecondary structures, has been constructed using the computer-aided software engineering (CASE) tool, Auto-mate. Auto-mate embodies the philosophy of the Structured Systems Analysis and Design Method (SSADM) which enables the logical design of computer systems. Our design will facilitate the building of large information systems, such as databases and knowledgebases in the field of protein structure, by the derivation of system requirements from our logical model prior to producing the final physical system. In addition, the study has highlighted the ease of employing SSADM as a formalism in which to conduct the transferral of concepts from an expert into a design for a knowledge-based system that can be implemented on a computer (the knowledge-engineering exercise). It has been demonstrated how SSADM techniques may be extended for the purpose of modelling the constituent Prolog rules. This facilitates the integration of the logical system design model with the derived knowledge-based system.     

Building an Information System for Collaborative Researchers: A Case Study from the Brain-tumor Research Domain

A Neuro-Oncology Information System (NOIS) has been designed and implemented to support collaborative brain-tumor research, and is being used currently by researchers around the nation. The NOIS serves two groups of brain-tumor researchers, each with complex organizational structures. The complexity of these structures adds greatly to the task of designing an information system to support brain-tumor research. In particular, a lack of a central source of authority among collaborating group members, and the constantly shifting understanding of research objectives and the means to achieve them, have significant impact on the NOIS design and implementation. In this paper, we suggest guidelines for designing, implementing and maintaining an information system in the face of continually shifting goals and priorities in the user community. © 1997 John Wiley & Sons, Ltd.
