new method to determine buffer size for high risk project environment in critical chain method

Critical Chain Project Scheduling: Utilizing Uncertainty for Buffer Sizing

In this paper, we introduce a method for buffer sizing in Critical Chain project scheduling. Proposed approach considers lognormal distribution for modeling activities’ execution time. The inherent uncertainty of activities considered as a main factor to size the buffer in proposed method. For comparing with traditional methods we used problems presented in literature. The results depict that p...

A new method to determine a well-dispersed subsets of non-dominated vectors for MOMILP ‎problem

Multi-objective optimization is the simultaneous consideration of two or more objective functions that are completely or partially inconflict with each other. The optimality of such optimizations is largely defined through the Pareto optimality. Multiple objective integer linear programs (MOILP) are special cases of multiple criteria decision making problems. Numerous algorithms have been desig...

A New Method for Spatial Health Risk Assessment of Pollutants

Background: The area of contaminated lands exposed to the health risk of environmental pollutants is a matter of argument. In this study, a new method was developed to estimate the amount of area that is exposed to higher than normal levels of Cr, Mn, and V. Methods: Overall, 170 soil samples were collected from the upper 10 cm of soil in an arid area in central part of Iran in Semnan Provin...

An Assessment Method for Project Cash Flow under Interval-Valued Fuzzy Environment

Effective project management requires reliable knowledge of cash required in different stages of project life cycle. Getting this knowledge is highly dependent on sophisticated consideration of project environment. Nature of projects and their environments are associated with uncertain conditions. In this paper, a new project cash flow assessment method based on project scheduling is proposed t...
