Abstract
Some surplus soil coordination models between construction sites have been developed in order to make efficient soil transport plan for recycling of surplus soil. However these models can't consider the uncertainties related to construction commencing time, duration, and soil volume, except of Minami and Simazu Model (1988) that can deal with the only uncertainty of construction commencing time. In this study, a model dealing with all of the above uncertainties was developed by improving the Minami and Simazu model. Then the model's applicability was shown through the application.
