In this
paper, a fish farm was modeled using the Lexicographic linear goal programming
approach due to incommensurability in objectives. The study considered the fish
farming plan with two sizes of catfish from stocking to harvesting at
four-month intervals. The multi-objective goals developed are required raw
materials feed, water, light (resource utilization), sales revenue, profit
realized, labor utilization, production costs, and pond utilization. The
developed model was tested using related data collected from the farm records
with the use of TORA 2007 software. The compromised solution from the results
showed that the developed model is an efficient tool for decision-making
process in the fish farm business organization.
