JAYAWARDANE, A. and PRICE, A., 1994. A new approach for optimizing earth-moving operations. Part 2. Proceedings of the Institution of Civil Engineers. Transport, 105 (4), pp.249-258.
Part I of this Paper describes the development of a comprehensive model (RESOM) achieved by combining computer simulation and linear/integer programming
(LP/IP) techniques. In Part II, the application and experimentation with RESOM is sytematically
explained using two case studies. The first case study reveals that about 20% of
earthworks costs estimated by contractors could be saved through the application of RESOM. The advanced use of RESOM is illustrated using a second case study
and involves the testing of different plant teams for individual haulage operations, the setting up of new borrow/disposal
sites, the incorporation of project duration constraints and the determination of the optimum construction plan for
various optimality criteria. A sensitivity analysis performed to investigate the
effect of average sectional interval and
plant selection is also presented.
