A new version is introduced of the bilevel integrated system synthesis method intended for optimization of engineering systems conducted by distributed specialty groups working concurrently in a multiprocessor computing environment. The method decomposes the overall optimization task into subtasks associated with disciplines or subsystems, where the local(More)
Publicly accessible bug report repositories maintained by free / open source development communities provide vast stores of data about distributed software problem management (SWPM). Qualitative analysis of individual bug reports, texts that record community responses to reported software problems, shows how this distributed community uses its SWPM process(More)
Our empirical research has shown that a predominant structural feature of defect tracking repositories is the evolving "bug report network" (BRN). Community members create BRNs by progressively asserting various formal and informal relationships between bug reports (BRs). In one F/OSS bug repository under study, participants assert two formal relationships(More)
This paper reports the results of a study into the use of discrete journal article components, particularly tables and figures extracted from published scientific journal articles, and their application to teaching and research. Sixty participants were introduced to and asked to perform searches in a journal article component prototype that presents(More)
All software exhibits operational problems as well as opportunities for redesign. How software projects handle problems and ongoing redesign efforts – Software Problem Management or "SWPM" – is not well understood, especially in open distributed communities such as Free/Open Source Software (F/OSS) projects. Little is known about the factors that influence(More)
F/OSS research faces a new and unusual situation: the traditional difficulties of gathering enough empirical data have been replaced by issues of dealing with enormous amounts of freely available data from many disparate sources (forums, code, bug reports, etc.) At present no means exist for assembling these data under common access points and frameworks(More)
This study looks at the data communicationsnetwork management organization (NMO) within alarge financial institution and appliesconcepts from Computer-Supported CooperativeWork (CSCW) and other domains to developtechniques for describing work within this andother similar organizations. Networkmanagement is one form of infrastructuremanagement, which is(More)
