A product development process is composed of many design activities and the ESHLEP-N model can describe some special features of design activity in detail, such as randomness of its duration, uncertainty of its interruption and complexity of design iteration.
Our goal was to assess how frequency and duration of composite samples influence uncertainty of the attenuation estimates in WWTPs and rivers.
The findings demonstrate that risk matters in PV policy design, and that a "price tag" can be attached to specific policy risks, such as the duration of administrative processes or uncertainty induced by an approaching capacity cap.
But man-made disasters such as oil slicks represent an entirely different type of risk in terms of severity, duration, and uncertainty.
Finally, work is required to determine how different levels of uncertainty in the duration of an activity affects the relationship between the level of correlation and plan optimality.
Trofin (2004) and Flood et al. (2004) implemented a Monte Carlo analysis using the LSM framework to assess the impact of uncertainty on project duration, and activity idle time.
This paper studies the impact of uncertainty on total duration (i.e., make-span) for implementing all features in operational release planning.
To determine the influence of uncertainty regarding the duration of visits or tests on the costs per patient year, we performed the following uni-variate sensitivity analyses: 1.
The second type of uncertainty principle: local duration-conditional standard deviation.
13 The paucity of data informing the treatment of TB/HIV co-infection has recently been highlighted, with particular uncertainty for duration of therapy.
