Development of Optimization Model for Herd Distribution in Animal Husbandry

Inventory management issues are becoming increasingly complex, and the search for new and more effective methods of dealing with them is becoming necessary. The goal in optimal inventory management is to minimize the amount of all costs associated with creating and storing inventory. Inventory management costs vary in constant or variable magnitude with respect to time and are directly dependent on inventory volume. Analytical models are used to determine the changes in the inventory volume situation. The purpose of the analytical models is to present basic patterns in the processes under study, to describe the impact that has occurred and to determine its cause. Based on the results, resources and tools used in the specific problem are identified. Optimization models are used to determine the most appropriate values for them when considering the owners' objectives and animal husbandry conditions.The study proposes a model to find the optimal values of the factors (resources and tools), which are represented by a mathematical relationship with the performance criteria in the objective function of the model, subject to their set constraints for the considered problem. It processes data for a pig farm and establishes the allocation of costs according to the amount of feed for rearing the animals and the number of pigs reared for sale. On the basis of the results obtained, solutions are proposed to increase the number of pigs reared in the different groups, thereby increasing the amount of sales. The study also contributes to more accurate planning of the groups of pigs kept on the farm. In addition, the model determines the optimal number of animals to be kept on the farm, while respecting health standards regarding the space needed for each animal and the building capacity. [3], [4]
