ST-89-16 A thesis submitted in partial fulfilment of the requirements for t h e degree of Master of Engineering, School of Engineering and Technology Thesis (M.Eng.) - Asian Institute of Technology, 1989 Several applications of quantitative models are studied in the present research, starting with the estimation of excavation quantities and identifying and locating disposal sites. The quantities have been estimated from the cross sections of canal excavation taken at 1 km interval along the route adopted by TAMS in their 1973 study. Three disposal sites for ex cavated material have been identified along the route and their capacities estimated from the areas available at each site and considering a dumped hight of 50 m. Quantitative models have been used for the construction planning of equipment for drilling, muck loading and hauling. Application of queuing model resulted in selecting and matching appropriate loading and hauling equipment yielding minimum unit cost. This study also included the analysis showing how the number of servers influences the unit cost for different haul distances. The results of the analysis show that for the range of haul distances 0 to 3 km , ~ to 9 km and 10 to 11 km four servers, three-servers and two-servers respectively are economical. Above 11 km haul distance single server system gives minimum unit cost. Transportation model is used to determine optimal allocation of earth from different sources to different destinations. A comparative computation of hauling cost for single-server case and combination of multi-server vis-a-vis single-server was carried out by using transportation model. In both cases cost coefficients for transportation matrix are calculated using queuing model. Results show that the hauling cost in the later case is about 5% lesser. Thus, the models minimize the cost for loading and hauling of earth. Economic life of the equipment is determined minimizing the cumulative cost. Replacement decisions for the dump trucks, shovels and the drilling machine are based on their economic lives. Economical life for the shovels and the dump trucks works out respectively as 7 and 6 years though their probable life spans are 10 years and that for the drilling machine it is 3 years against the prescribed 5 years ultimate life. Yearly procurement schedule for equipment is prepared based on replacement at their economic life which results in the complete utilization of the equipment on this project for the purpose of amortization.
