碩士 / 國立中興大學 / 土木工程學系所 / 100 / Earthwork is an important part of civil engineering mainly including digging, filling, moving, and stacking. Earthwork and other engineering projects can be arranged in time series through the construction schedule; in spatial allocation, because of project design and varied topography, different construction sites have different quantity demanded.
Earthmoving refers to allocating resources between multiple construction sites and fit the requirements in each construction sites. Current status of resources allocation usually relies on professional engineers'' personal experience but without scientific evidence. It may increase additional cost easily by ineffective earthmovings. Most of previous study did not premeditate the construction schedules which construction sites did not start together, so that earthmoving could not complete. Although some researches had taken construction schedule into account, because of the requirements from all the construction sites were defined before the model was built, the earthmoving still could not allocate resources flexibly.
Our study uses MIP to optimize earthmoving by considering the construction schedules and the external resources. The data for tested our model came from Chen (2008). According to our result, our model can save up to about 22% cost compared to original model in the daily traffic limit 7194 cubic meters.
