Fleet selection for earthmoving operations using queueing method

摘要: This research concentrates on presenting a methodology for equipment fleet selection earthmoving operations. The is incorporated in developed computer module " FLSELECTOR ", Fleet SELECTOR, capable of assisting the users making management decisions required operations, such as determining size and number trucks excavators, haul road lengths surface conditions, etc.... These are based calculated output all feasible fleets. Mathematical solutions queuing models that apply to excavation work were derived coded using commercially available tools, Microsoft Excel 2000 Visual Basic Application (VBA), subset popular application development language, Basic. Two case studies, an actual project hypothetical case, presented order illustrate effectiveness performance proposed model with comparison results deterministic simulation methods.
