A decision support systems approach to adjust maintenance float system availability levels

In this paper, a decision support system (DSS) is designed to predict the system availability levels for equipment maintenance float problems. The DSS is developed by using the analytic hierarchy process (AHP) to prioritize the improvements made in the maintenance management practice through the adoption of total quality management (TQM). The resulting regression metamodel can be used to predict and explain system availability. Sensitivity analysis can be easily generated through the DSS. The application of this DSS helps to effectively control the cost of maintenance floats as a result of TQM implementation, generates quick solutions, and provides the decision maker with the flexibility of carrying out sensitivity analysis and planning for the future by looking at the long-term impacts of TQM on the maintenance float system.     

An instrument for the measurement of customer perceptions of quality management in the software industry: An empirical study in India

Most of the available literature on quality management is based on management’s perception; few studies examine critical issues of quality management from the customer’s perspective, especially in the software industry. In order to gain an insight into what customers expect from a product/service, an analysis of quality management from customer’s point of view is essential. Such an understanding would help the managers to adopt strategies that can enhance the satisfaction level of their customers. The present study highlights the critical factors of quality management in the software industry from the customer’s perspective. Six critical factors are identified: and an instrument, comprising these factors, is developed and validated so as to measure the customer’s perception of quality management in the software industry.

Total quality management: An approach & a case study

For the last decade, American companies have been playing catch-up in the area of quality and productivity. Japanese companies and other foreign competitors have moved into markets that were once dominated by American companies, by producing higher quality products. The problem to date in the U.S. has obviously not been the lack of resources or documentation on quality and improvement programs, but the misdirection of these programs and the lack of total management commitment. Total Quality Management (TQM) is seen as an effective method that will accomplish the task of higher quality levels, and increased productivity.

The purpose of Total Quality Management is to implement a process that is long term and continuous, in which all of management participates in establishing continuous improvement initiatives throughout the organization, beginning with their own function in the organization. TQM integrates the fundamental techniques and principles of Quality Function Deployment, Taguchi Methods, Statistical Process Control, Just-In-Time, and existing management tools into a structured approach. The primary objective of this approach is to incorporate quality and integrity into all functions at all levels of the organization.

This paper examines the TQM process, philosophy, concepts, attributes and how it can be used to develop a “quality-based” culture. The paper also examines the introduction and implementation of the TQM process at an electronic's manufacturer.     

Facilitating implementation of total quality management through information technology

There is growing interest in the service industries in the adoption of quality management programs to improve their operational efficiency and market competitiveness. Deming’s total quality management (TQM) philosophy is one of the well-known ones. The TQM emphasizes continuous improvement through statistical control and the continuous training of people in the principles of quality management. One of the main implementation issues is the large volume of data that must be statistically analysed. Although recent researches have reported on how TQM is applied in various industries, few have discussed the importance of information technology in ensuring a successful TQM program. This paper reports on the application of information technology in the TQM process and how it can support management decisions. A case example is included to support these views.     

An integrated multidimensional process improvement methodology for manufacturing systems

In this paper, an integrated multidimensional process improvement methodology (IMPIM) is formulated to address the yield management, process control and cost management problems of a manufacturing system. Simulation is used as a platform to implement the integrated multidimensional process methodology by incorporating the productivity, quality and cost dimension in a unified, systematic and holistic manner. Total Quality Management (TQM) addresses the quality parameters and Activity-Based Costing is used to manage the cost dimension of the system. Discrete event simulation is then used as a platform to perform process reengineering (Business Process Reengineering) and process improvement (TQM). The general implementation framework of the IMPIM is given with a step-by-step explanation. A conceptual discussion is also provided for the integrated methodology. The generic IMPIM is then formulated and the detailed implementation procedures for two case studies are compared with the generic methodology.

QoS Management by Means of Application Control

The complexity and sophistication of integratedbroadband networks call for a broad repertoire ofmanagement methods. Foreseen intensive competition ofthe communications market, and the upgrade ofend-customer's satisfaction as the focal point of anymanagement policy, raise a very important problem: howto utilize efficiently the resources of the networkwhile maintaining the Quality of Service (QoS) provided to end-users within a pre-negotiated range. Inthis paper, a QoS management architecture for multimediaapplications based on an application control scheme isproposed. Adhering to the Total Quality Management (TQM) paradigm, we let management span over theentire communication stack, the entire network(end-to-end) and the entire call duration. Applicationcontrol scheme aims to meet pre-specified QoS goals by adjusting the traffic produced by theend-user applications. The adjustment technique is basedon the notion that each multimedia session is allowed tooperate on a set of discrete application quality levels. A method for monitoring and assessingthe end-user perceived quality is presented. Themathematical problem of optimal resources allocation andan associated heuristic are specified. Finally, a specific instantiation of the introduced QoSmanagement architecture on a real testbed is describedand experimentation results are presented andevaluated.     

Quality management and the work environment: an empirical investigation in a public sector organization

The integration of quality management initiatives, particularly total quality management (TQM), and ergonomics has received increasing attention from scholars and practitioners. Above all, the question of how TQM programs relate to ergonomic aspects of organizational design and culture is at the center of this discussion. This study examines how elements of a "typical", Deming-inspired, TQM program in the public sector interact with the work environment. Elements of the TQM program were defined and measured using the Malcom Baldridge Award criteria. The specific elements examined were "Management Support of Quality", "Information and Analysis", "Human Resources", "Processes and Quality Results", and "Customer Focus and Satisfaction". The relationship between these TQM elements and the work environment were defined through five separate hypotheses. The work environment was described by the constructs "Supervisor Support", "Task Clarity", "Task Orientation", and "Innovation". Data were obtained through survey questionnaires administered to employees of four departments in a municipal government organization. Results supported three of the hypotheses, but produced some unanticipated outcomes with regard to the other two. Namely, "Management Support of Quality" was significantly related to "Supervisor Support", "Task Orientation", "Task Clarity" and "Innovation"; "Human Resources" was significantly related to "Supervisor Support"; "Processes and Quality Results" was significantly related to "Task Orientation" and "Innovation". Contrary to predicted "Information and Analysis" was negatively related to "Innovation", and "Customer Focus" was unrelated to any of the outcome variables. The relationships between these TQM elements and work environment dimensions are discussed. Implications for TQM and ergonomic practice are analyzed, and directions for future research proposed.     

Security as a contributor to knowledge management success

Security is an important topic, but is it important for Knowledge Management (KM)? To date, little mainstream KM research is coming through with a security focus. This paper asks why, and proposes that security be integrated into KM success models. The Jennex and Olfman (International Journal of Knowledge Management 2(3):51–68, 2006) KM success model is used to illustrate how security, specifically risk management, and the National Security Telecommunications and Information System Security Committee (NSTISSC) security model can be applied to KM management support and governance and KM Strategy. Finally, two case studies are provided that illustrate the application of risk management through governance to KM.     

Extending TINA with Secure On-Line Accounting Services

Concepts and principles of TINA (Telecommunications Information Networking Architecture) are introduced with the objective of correcting problems of the current centralized service control and service data model in an IN (Intelligent Network). It is becoming increasingly clear that the future sophisticated telecommunication services, e.g., multimedia, and multi-party conferencing, breaking away from the traditional telephony call model will need the solutions for rapid and efficient introduction, deployment, operations, and management.In this paper, we discuss accounting features and requirements, as well as security services in the TINA management context. We will introduce and present an implementation of a model for a security management, based on secure objects, cryptography and certificate distribution. In order to provide secure services, secure objects that have security functionality, such as authentication and access control, have been defined. Secure objects in our model are CORBA objects. The security domain is also called SBS (Security Base Server), provides security services and has an SMIB (Security Management Information Base) that contains security policies, cryptographic algorithms, and other relevant information. A prototype has been implemented and some experimental results are presented.
