new method to determine buffer size for high risk project environment in critical chain method
نویسندگان
چکیده
in this research, a method for determining feeding buffer sizes in critical chain project scheduling is introduced. the method integrates project characteristics into the formulation as well as environment project risk. resource tightness, environment risk and network morphology incorporate into the formulation. the method is tested and compared to three commonly suggested methods in the literature, the cut and paste method, the root square error method and adaptive procedure with resource tightness. the comparison is done by means of a simulation study using the kolicsh hartman data set. the test results indicate that all of the suggested methods generate better buffer sizes; therefore, they provide sufficient protection against the delays in project completion time.

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...

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...

15 صفحه اولA 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...
