Work-Scheduling Model for an Open Cast Coal Mine in Turkey with Integer Programming
Tunçbilek Open Cast Coal Mine of Garp Lignite Enterprise (GLI) is located in Kütahya, Turkey and the overburden removal operations are carried out by using Truck/Shovel Systems which is faced with the problem of changing number of trucks due to equipment breakdowns. The maintenance of failed trucks are planned to occur at fixed scheduling days. It is required to determine the operating number of truck drivers for each operating shifts in a weekly planning horizon. A simple Integer Programming model is developed using LINGO software to determine the optimum number of truck drivers required to satisfy the variable number of trucks for each operating shift. The developed model schedules the trucks drivers optimally for each operating shift in a weekly scheduling period.
