Fundamental to the development of redundant software techniques (known as fault-tolerant software) is an understanding of the impact of multiple joint occurrences of errors, referred to here as coincident errors. A theoretical basis for the study of redundant software is developed which 1) provides a probabilistic framework for empirically evaluating the(More)
This paper describes our experience in using a multimedia project management and software engineering environment, Decision-based Hyper-multimedia CASE (DHC), to support the Low-Visibility Landing and Surface Operations (LVLASO) project at the NASA Langley Research Center. 1 The purpose of the LVLASO project is to allow pilots to land and taxi airplanes(More)

A study of computer engineering tool integration using the Portable Common Tool Environment (PCTE) Public Interface Standard is presented. Over a lO-week time frame, three existing software products were encapsulated to work in the Emeraude environment, an implementation of the PCTE version 1.5 standard. The software products used were a computer-aided(More)
