Manufacturing Execution System

MES (manufacturing execution system) is the comprehensive system that controls all the activities occurring on the shop floor. It begins with all the various orders from customers, the MRP system, the master schedule, and other planning sources; and then builds the products in the most effective, low cost, expedient, and high- quality way possible. A comparative example occurs in the construction business where the construction team (MES) builds a tower from the architectural plans (inputs from MRP, Master schedule, etc.)
