“…Some of the more well-known formal expert-based prospective techniques include PERT [Dodin, 1985;Lootsma, 1988], GERT [Seyedghasemipour, 1987], and Critical Path Method [Arsham, 1993]. These approaches tend to be more applicable to optimizing project management, where the component technologies and desired end targets and schedules are fairly well understood.…”

Database Tomography (DT) is a textual database analysis system consisting of two major components: 1) Algorithms for extracting multiword phrase frequencies and phrase proximities (physical closeness of the multiword technical phrases) from any type of large textual database, to augment 2) interpretative capabilities of the expert human analyst. DT was used to derive technical intelligence from a hypersonic/supersonic flow (HSF) database derived from the Science Citation Index and the Engineering Compendex. Phrase frequency analysis by the technical domain expert provided the pervasive technical themes of the HSF database, and the phrase proximity analysis provided the relationships among the pervasive technical themes. Bibliometric analysis of the HSF literature supplemented the DT results with author/journal/institution publication and citation data. Comparisons of HSF results with past analyses of similarly structured near‐earth space and Chemistry databases are made. One important finding is that many of the normalized bibliometric distribution functions are extremely consistent across these diverse technical domains.

“…Arsham [2] constructed a linear programming (LP) formulation to find the critical path of PERT networks by estimating a time for each activity duration. Kulkarni and Adlakha [26] developed a continuous-time Markov process approach to PERT problems with independent and exponentially distributed activity durations.…”

“…The existing models are mainly appropriate to plan and control R&D projects and long-term projects when designing or developing new industrial or populated areas, but our proposed model is appropriate in the building construction, when creating and building similar successive installations along the time horizon. Most of regarded sources use heuristic approaches like Arsham [2] and Golenko-Ginzburg et al [14][15][16][17][18][19][20][21][22], based on simulation, to solve the problem, but we use discrete-time approximation technique, which is proved to approach the optimal solution. Finally, the proposed model is the first, which tries to solve the TCTP in a PERT network by modelling it as a queueing network.…”
