| dc.description.abstract | Competitive pressures on power plants have seen them attempting to reduce their
operating expenses for profitable operations. In India, the plants use wagons of the Indian
Railways to transport coal from the mines (in case of domestic coal) or from the ports (in
case of imported coal). Once these loaded railway wagons have reached the power plant,
they need to be unloaded and released within a stipulated time frame. If there is any delay
beyond the stipulated time, the power plant has to pay penalty cost to the Indian
Railways. In this paper, we describe an analysis of the underlying causes behind these
delays. We use correlation analysis, queuing theory and simulation to mathematically
model the coal arrival process in the company. The recommendation suggested by the
study is currently under implementation. | en |
