Identification of errors in software requirements through use of automated requirements tools Original Research ArticleInformation and Software Technology, Volume 31, Issue 9, November 1989, Pages 472-476JS Davis Close preview | Related articles | Related reference work articles AbstractAbstract | ReferencesReferencesAbstractErrors in software requirements tend to be more costly to correct the later they are detected. Use of automated requirements tools can help detect errors early in the software life-cycle. The paper describes a case study that demonstrated the capabilities of automated requirements tools in detecting errors in the requirements for a large management information system. Three different tools were applied to the same requirements document: Problem Statement Language/Problem Statement Analyzer (PSL/PSA), Input/Output Requirements Language (IORL), and Software Requirements Engineering Methodology (SREM). Each tool helped identify several hundred errors, many of which were associated with failures that occurred after system delivery.Article Outline?

An application domain is represented by a family of systems that have some features in common and others that differentiate them. A domain model is a problem-oriented architecture that captures the similarities and variations of the family of systems that compose the application domain. Because the application domain requirements capture the composite features of the members of the family, they are categorized as kernel (required by all family members) or optional (required by some family members). It is the optional features that determine the characteristics of a given target system. The relationship between the domain requirements and the object types in the domain model are captured by means of feature/object dependencies, which define the object types and prerequisite features needed to support a given feature. Software architectures are reused by selecting those features required in a target system and then tailoring the domain model, subject to the appropriate feature/object dependency constraints, to generate the target system specification.Article Outline?

This paper proposes a methodology and a tool to aid decision makers in evaluating and selecting the most appropriate package for their firm. The methodology deals with manufacturing resource planning (MRP) software and outlines two phases: the enumeration of an extensive list of criteria for MRP and the identification of a decision-making method to be used on the basis of these criteria. The analytic hierarchy process (AHP), also selected by the methodology, is applied to an actual case where a software package is selected for an industrial enterprise. Organizational and human implications resulting from the introduction of an MRP package are discussed.

Over the past years companies have been forced to alter their overall management strategies radically. Now, speed, flexibility, responsiveness, adaptiveness, and quality have become increasingly important. Companies must have the ability to respond to sudden market changes; and in order to meet these new requirements, the company has to master new technologies and new organizational forms. At all levels, organizations have to deal with quick and high quality decisions, and this creates the need for not only conventional support systems, but also systems that are able to advise the decision makers in performing complex and knowledge-intensive tasks.In particular, industrial scheduling within the production management (PM) domain is addressed. In general, industrial scheduling using analytical techniques is an NP-complete problem. Scheduling problems have been the target of a substantial amount of research within the operations research (OR) community, yet conventional OR techniques applied to scheduling have had little impact in industry. Analytical results have been achieved only for problems of moderate complexity.Using AI techniques the inherent complexity of the scheduling problem can be reduced to a tractable size. We present a methodology for synthesizing detailed production schedules, based on the state-space search paradigm within AI. The paradigm is extended to include heuristic pruning, giving the ability to utilize the company-specific production strategies and knowledge employed in manual planning. Finally, we present a generic, industrial scheduling system, PLATO-PS, using these techniques.

Mani Close preview | Related articles | Related reference work articles AbstractAbstract | ReferencesReferencesAbstractUnderstanding co-operative knowledge systems is becoming a central issue in AI research. The questions centre around the complexity of managing separate knowledge sources in terms of heterarchical and hierarchical organisation structures, and convergence of the planning and design cycles. Engineering design is characterised by no predetermined solution path and by the integration of multiple domains of knowledge at various levels of abstraction. A conceptual blackboard architecture is introduced to model co-operation among disparate knowledge sources associated with engineering design on a software framework. A trade-off approach brings in co-operation among the disparate knowledge sources. For pedagogical purposes, the floorplanning of VLSI circuit design is simulated using the framework.Article Outline?

Careful attention to the real objectives, user requirements, and constraints upon implementation are paramount at this stage. A structured set of functional requirements allows the scope of the information system to be defined and useful feedback obtained from users, before large implementation commitments are made. The information system must be flexible and able to cope with technology changes and international standards as they mature. An interfacing approach based on international standards is described. The sheer size of the systems means that a structured approach based on functional requirements is essential. The functional requirements must describe the flow of information as well as the support activities needed for the information system. Existing hardware, software and skills must be used, and a policy adopted for maximum use of commercial software solutions. Some software tools may need to be defined as project standards.

The System-on-Chip (SOC) design service industry is emerging at the moment when E-commerce has already become one of the most efficient marketing channels. Albeit the SOC design service firms intended to provide services over the internet, the e-business model definitions for silicon intellectual property (SIP) commercialization or SOC design services are not easy for both aspects of technology as well as business development. The authors proposed and verified a novel multiple criteria decision making (MCDM) based e-business model definition framework for maximizing the value-added of online SOC design services.618 The Virtual Maintenance System: A Computer-Based Support Tool for Robust Design, Product Monitoring, Fault Diagnosis and Maintenance Planning Original Research ArticleCIRP Annals - Manufacturing Technology, Volume 49, Issue 1, 2000, Pages 91-94F.J.A.M. van Houten, F. Kimura Close preview | Related articles | Related reference work articles AbstractAbstract | ReferencesReferencesAbstractDigital (geometric) product models can be used for maintainability analysis and maintenance planning. It is not feasible to build digital product models for maintenance purposes only, but if a digital product model is available, it may be used to support many maintenance-related engineering tasks. Examples are: Product life cycle simulation (the influence of product use on product performance), deterioration analysis (the influence of wear on product function), Failure Mode Effect Analysis (FMEA), product model-based monitoring (to relate sensor signals to failure modes), failure diagnosis, disassemblability analysis (for repair and replacement), maintenance ergonomic analysis (to ease the work of maintenance personnel), etc.At the University of Tokyo, a Virtual Maintenance System has been developed to support the activities mentioned above. The system makes it possible to relate predicted product behaviour and specific signals, which can be detected by sensors and can be used to avoid catastrophic failure. This creates better possibilities for condition-based maintenance and Design for Maintainability. Future CAD systems should support product life cycle issues right from the start of the design process.

Speedie Close preview | Related articles | Related reference work articles AbstractAbstract | Figures/TablesFigures/Tables | ReferencesReferencesAbstractBackgroundOne of the most important factors for the success of health information technology (IT) implementation is users acceptance and use of that technology. Thailand has implemented the national universal healthcare program and has been restructuring the countrys health IT system to support it. However, there is no national data available regarding the acceptance and use of health IT in many healthcare facilities, including community health centers (CHCs). This study employed a modified Unified Theory of Acceptance and Use of Technology (UTAUT) structural model, to understand factors that influence health IT adoption in community health centers in Thailand and to validate this extant IT adoption model in a developing country health care context.MethodsAn observational research design was employed to study CHCs IT adoption and use. A random sample of 1607 regionally stratified CHCs from a total of 9806 CHCs was selected. Data collection was conducted using a cross-sectional survey by means of self-administered questionnaire with an 82% response rate. The research model was applied using the partial least squares (PLS) path modeling.ResultsThe data showed that people who worked in CHCs exhibited a high degree of IT acceptance and use. The research model analyses suggest that IT acceptance is influenced by performance expectancy, effort expectancy, social influence and voluntariness. Health IT use is predicted by previous IT experiences, intention to use the system, and facilitating conditions.ConclusionsHealth IT is pervasive and well adopted by CHCs in Thailand. The study results have implications for both health IT developmental efforts in Thailand and health informatics research. This study validated the UTAUT model in the field context of a developing countrys healthcare system and demonstrated that the PLS path modeling works well in a field study and in exploratory research with a complex model.Article Outline1.
