Economic aspects of a national electronic reserve service (NERS) were explored using Ithink Analyst, a modelling software package. A model was developed and simulations were used to monitor the effect of variations in the values of key model elements. The model was based on developments within...

As the World Wide Web continues its tremendous rate of development, providers of services on the web have difficult decisions to make regarding the deployment of new technologies: should they begin deployment of technologies such as HTML 4.0, CSS 2, Java, Dublin Core metadata, etc., or should...

At the heart of the Okapi system is a formula referring to some half a dozen variables, which estimate the probability that a given document is relevant to a given query. User interface design for Okapi aims to present its search capabilities as clearly and simply as possible. But between the...

Applying total quality management (TQM) to the software development process can control software quality and productivity. Selecting suitable tools for the TQM process can strengthen the capability of software quality assurance. This article provides a manager’s guide to implementing a total...

It is important to take into account the trade‐off between hardware and software systems when total computer‐system reliability/performance is evaluated and assessed. Develops an availability model for a hardware‐software system. The system treated here consists of one hardware and one...

The contents and function of a computer package to fit reliability models for computer software are outlined. Parameters in the models are, in the first place, estimated by maximum likelihood estimation procedures. Bayesian estimation methods are also used and are shown to give estimates with a...

Explores the issue of software development process improvement. Total quality management (TQM) tools have been studied as possible means to improve the quality of the software that is becoming an important part of organizational processes. The TQM philosophy that has been so successfully applied...

Most of the existing software reliability models assume time between failures to follow an exponential distribution. Develops a reliability growth model based on non‐homogeneous Poisson process with intensity function given by the power law, to predict the reliability of a software. Several...

Develops an optimization model to optimize software quality within budget and time limitations. Software quality is described through quality factors. This model assumes a non‐linear relationship between quality factors and the effort spent in the development phases. Enables a software manager...

Considers an extension of the non‐homogeneous Poisson process to describe the software failure process more appropriately. This extension introduces a new structure for the intensity function of the non‐homogeneous Poisson process. Using this intensity function, develops a mathematical model...
