| dc.description.abstract | A study was conducted at Mumias Sugar Company to identify the parameters that determine
the flow rate of cane into and out of the factory's Cane Yard between November, 1991 and
May, 1992. The study utilized current as well as previously recorded (historical) data where
available.
Statistical analysis was carried out on all the data that was gathered. From the analysis,
curves were fitted using the chi-square goodness of fit test. Equations that described the
service times of all the unloading equipment in the yard were derived.
A computer simulation model of the Cane Yard operations was developed. The model
developed was capable of simulating the operations of the factory's Cane Yard. Cane inflow
rates, milling rates, stockpile build-up in the yard and the average waiting times of all the
trailer types were derived from the model. Simulated and actual Cane Yard parameters were
compared.
The model was used to determine the possibility of Mumias Sugar Company operating only
two daily transportation shifts of 8 hours, while satisfying the daily mill requirements. This
was found possible by increasing the hourly delivery rates of basket type trailers so that the
majority of the cane hauled into the yard by bundled cane trailers during the first 16 hours
of operation is stockpiled. However, the average waiting time for basket type trailers may
become the limiting parameter, particularly when there is a mill breakdown. | en |
