Case Study: Optimal Facility Allocation in a Robotic Milking Barn

A milking robot is a recent technological development; therefore, there are few precedents and little experienceto draw upon when designing robotic milking barns. There is wide diversity among farms, so the optimal layout may varyaccordingly. We developed a behaviorbased simulation model adjustable for any farmer or site. We improved it by using ametamodel, which allows a global optimum to be found. Under the given condition of two specific farms, it resulted in theoptimal facility allocation: Farm A, 1 robot, 36 forage lane positions, 60 cubicles (free stall), and 71 cows; Farm B, 2 robots,3 water troughs, 103 forage lane positions, 105 cubicles, and 132 cows. The optimal layouts calculated in this study are uniquefor each farms specific characteristics, but the design methodology developed is universally applicable.
