This document discusses using the Cuckoo Optimization Algorithm (COA) to solve a production planning problem. It provides background on COA and how it works, modeling the production planning problem with objectives and constraints. The COA is implemented on a 3-product, 5-period example problem. Results show COA finds better solutions faster than Genetic Algorithm and provides answers close to commercial solver Lingo. COA is thus shown to be an effective method for solving this type of constrained nonlinear production planning problem.
