House Size Determination for Poultry Production
This research focuses on determining the size (or capacity) and an appropriate number of pullet and hen houses which are needed to raise chicks each week along the planning horizon with the objective to minimize the loss incurred. A three-phase heuristic algorithm was developed. The first phase algorithm was developed to determine the sizes of pullet and hen houses. Then, the second phase algorithm based on neighboring search method was developed to improve the solutions obtained from the first phase algorithm. Finally, Genetic Algorithm was developed in the third phase to determine the appropriate number of pullet and hen houses required to meet egg demands in the planning horizon. The algorithm was implemented to solve the problems of the current practice of a farm in northeastern Thailand. The performance of the algorithm was measured using the parameter relative improvement, which compared the total loss values predicted by the algorithm and those resulting from the current practice of the farm. Results of this study show that the algorithm was very efficient. The relative improvement values were between 6.97–66.91%, with an average of 46.23 per cent.
