In the software reliability growth phase, the nature of the failure data is, in a sense, determined by the software testing process. A hybrid model is proposed for medium and long-term software failure time forecasting in this paper. The hybrid model ...

In 2005, a system trouble occurred in the Tokyo Stock Exchange Order System, which caused a loss of more than 40 billion yen to Mizuho Securities and Mizuho filed a lawsuit demanding compensation for the loss to the Tokyo Stock Exchange (TSE).The ...

A Virtual Storage Architecture (VSA) is a storage controller deployed as a virtual machine on a server with a hypervisor. The advantage of VSA is to leverage shared data storage services without procuring additional storage hardware, which is a cost ...

In 1978, Honeywell began developing its flight management system (FMS), putting the first FMS into service as standard equipment in 1982 on the Boeing B757 and B767. Now, every major aircraft manufacturer includes a Honeywell FMS in the cockpit. In ...

Memory bugs in C/C++ programs severely affect system availability and security. This paper presents First-Aid, a lightweight runtime system that survives software failures caused by common memory management bugs and prevents future failures by the same ...

Performance related problems are a key aspect in the software development process (SDP). In particular an early integration of performance considerations inside the SDP has been recognised during last years as an effective approach to speed up the ...

Checklists are an important part of code and design inspections. Ideally, they aim to increase the number of faults found per inspection hour by highlighting known areas of previous failure. In practice, although some researchers have quantified ...

There are a number of authors who have documented problems with our software development processes. Unrealistic schedules and budgets, with continuing steams of requirements changes lead to projects with a high risk of failure. There is too often only a ...

Many applications demand availability. Unfortunately, software failures greatly reduce system availability. Prior work on surviving software failures suffers from one or more of the following limitations: Required application restructuring, inability to ...

Requirements engineering experience shows that failing to look at all aspects of the problem space results in missing or incorrect requirements. The author provides a systematic approach for identifying which parts of the world require attention, along ...

Traditional Black box software testing can be effective at exposing some classes of software failures. Security class failures, however, do not tend to manifest readily using these techniques. The problem is that many security failures occur in stressed ...

This note summarizes conclusions from a three year study about why released software fails. Our method was to obtain mature-beta or retail versions of real software applications and stress test them until they fail. From an analysis of the causal faults,...

Abstract: The author describes a component bused checkpointing code generation tool. Scientific applications that require long computation runtimes experience the risk of hardware or software failures. Failure during a long computation requires that the ...

Too often, when doing software reliability modeling and prediction, the assumption is made that the software involves either a single module or a single node. The reality in today's increasing use of multi-node client-server systems is that there are ...

Over the past two decades, substantial research efforts have been devoted to the design and development of high assurance systems, including general approaches and specific systems. Researchers in fault tolerant systems have developed effective ...

The goal of software inspection and test is to reduce the expected cost of software failure over the life of a product. The authors extend the use of defect triggers, the events that cause defects to be discovered, to help evaluate the effectiveness of ...

Assessing the reliability of software has been an active area of research over the past twenty years. To date, over a hundred software reliability models have been proposed. In this dissertation, we unify practically all of the existing software ...

The design, modeling, verification, and validation of highly reliable systems has become increasingly important in recent years. These systems, particularly those which are distributed or involve real-time constraints, are extremely complex and the ...

A decision-theoretic procedure for determining an optimal time interval for testing software prior to its release is proposed. The approach is based on the principles of decision-making under uncertainty and involves a maximization of expected utility. ...

An examination of the assumptions used in early bug-counting models of software reliability shows them to be deficient. Suggestions are made to improve modeling assumptions and examples are given of mathematical implementations. Model verification via ...
