The paper deals with the probabilistic network analysis for project completion time for various networks. As the project completion time depends on the path with the longest total completion time of all the given paths, it is expressed as a function of various activity durations according to known activity precedence relationship in the present study. As all the activity durations are considered probabilistic in nature, the total completion time is also a probabilistic variable and the determination of that requires rigorous mathematical analysis. Rosenblueth's two point estimates scheme is used for this non-linear probabilistic analysis problem and the results are compared with Monte Carlo Simulation. Such a study is conducted for two different networks and the results compared very well for both sample problems, both for uniform and normal distribution of the random variables which are the activity durations and the activity precedence relationships in the present study.
The interaction of technical ergonomic and product liability concepts within total quality engineering and managemens frameworks are evaluated. Risk management and insurance industry paradigms are examined as affecting value engineering and decision-making under uncertainty analysis. Joel Barker's "Future Edge" success paradigms are extended to risk analysis and ergonomics to achieve total quality and robustness. Examination of stochastic evaluation of engineered structures for life-cycle costing used with consideration of project alternatives is emphasized, and is an extension of work done by the authors in the areu of legal liability and technical insurance as related to engineering structures. Also considered are factors for safety and risk and project alternatives. Results show that for a complete assessment of project alternatives, concurrent interdisciplinary engineering methods are required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
