    Within operations management, production scheduling is a primary activity in goods or services organizations. Its function is to allocate resources to the operations of the production system in order to optimize and meet business objectives. A Flexible Flow Shop (FFS) is a productive in-line configuration with continuous material flow materials and products occupying the same facilities, where there is a common problem: finding the sequence of jobs or operations that optimizes a given objective function. In the present study, a production scheduling tool was developed in an FFS production system. It minimizes the time elapsed between the beginning of the processing of the first job at the first station and the completion of the last job at the last station known as makespan and finds the sequence of jobs to be processed. The case study is the organization CARPINTERÍA Y TAPICERÍA INTERNACIONAL. To solve this problem, tools such as VSM, process balancing, and a programming tool. with a mathematical model that references the conditions of the productive environment under study together with the use of a genetic algorithm. Based on several tests, it was demonstrated that the programming tool works properly, because it reduced the makespan by 85.2 minutes and structures the optimal sequence of jobs, representing a 15% improvement in the performance of the production system and higher productivity at the workstations
