FEATURED PAPER
Reliability of Projects: A Quantitative Approach
Part 1
Reliability and Productivity Models of the Elements of Work Flows
By Pavel Barseghyan, PhD
Abstract
Classical theory of reliability is applicable for the project’s reliability analysis. The main idea behind the mathematical modeling of the project’s reliability is to represent the entire project as a mixed system of parallel-serial human actions. Every human action, depending on the difficulty of the problems under investigation, with some probability can be successful or unsuccessful. Combining these probabilities with the structure of parallel-serial human actions, it is always possible to assess the probability of success or failure for the entire project.
In order to solve these problems we need to deal with the extended reliability block diagrams of projects that include communication and control related human actions.
This work consists of two parts.
The first part discusses issues related to the modeling of reliability and productivity of the elements of the reliability block diagrams of projects in the form of serial and parallel human actions. The second part of this work will be devoted to system-level issues of the assessment of project’s reliability parameters.
