Abstract

Pusher-loaded scrapers are important construction equipment in large earthmoving operations. Productivity of a pusher-loaded scraper varies greatly with the temperature or elevation, equipment performance, haul speed, haul-road conditions, method of loading, and number of scrapers per one pusher. Determining of the most economical scrapers fleet demands time-consuming calculation regarding the size of equipment, model name, and number of scrapers because it requires references of numerous performance charts or tables and repetitive use of complicated calculation. Moreover, operating conditions, which contain changeable parameters depending on the time, exaggerate this time-consuming problem. In addition, the calculation consumes a huge amount of time because operation conditions contain parameters which are changeable overtime. This research suggests the optimum economical pusher-loaded scraper fleet(OPSF) system which facilitates calculation process and deals with parameters effectively to complete on operation in decision making stage. The prototype of this program is developed using MATLAB. This provides the graphic user Interface where attribute values related to an operation are specified. When the parameters of an operation are specified by users, the system computes the productivity of each equipment, compares completion times of the operation, and recommends the most economical equipment fleet.
