    Industrial development has undoubtedly been favored, thanks to processes standardization and continuous improvement applied in most industries. Results of an efficient production, without any doubt, depends on an optimal planning based on standard times and production capacities, for this reason, in this research a time and motion study has been carried out at finishing area of Tannery Tungurahua S.A. In this study, the current working method for each of the finishing processes of San Marino school leather is initially described, through the elaboration of its flow chart elaboration and the identification of the activities corresponding to each procedure. Thus, analytical cursograms of each process are elaborated, in order to analyze in a more detailed way the product journey and type of operation that is carried out. Then calculation of the standard times are carried out, starting from activities coding, then both operators’ performance factor is calculated through the Westinghouse method, as well as supplements using established valuations by the ILO. Consequently, production capacities that will allow each process to be analyzed are calculated according to leather belts number that are manufactured, in this way, an average of 385 leather belts per day was obtained. As an improvement proposal, it is suggested to apply the SMED methodology for machines preparation and for general operations development, tool focused on the adhering, pigmenting and sanding processes, evidencing time reductions by 25.25%, 38.18% and 18.27% respectively. In the same way, it is proposed to apply the Theory of Constraints for the adhering process, which turned out to be the bottleneck requiring a time of 276.16 seconds. Finally, it is recommended to purchase an electric pallet truck that allows optimizing the transport times during batches transfer in order to improve handling units and to save operators integrity.

    The main objective of this degree work is to propose an improvement proposal in the production line that manufactures the star product of the IMPACTEX corporation in the city of Ambato, a company dedicated mainly to the manufacture of intimate apparel for women, men and children. The research carried out had a quali-quantitative methodological approach, of a qualitative nature because direct observation was carried out to obtain informative data from the corporation, on the other hand, in the quantitative approach the star product was determined with an ABC analysis, then the times of each activity necessary for the manufacture of the product were taken and the critical area was determined where a study of times and movements was carried out, with which the flow of the raw material, the standard time and finally the production capacity of each activity was determined. With the standard time calculated for each activity, we proceeded to determine a proposal for improvement using engineering tools, unnecessary transports were eliminated in order to subsequently carry out a balance of assembly lines, where the effective times of each operator were balanced and production was maximized. As a result of the elimination of unnecessary transports, an improvement of 23% in the operating ratio was obtained, as for the balance of lines, an increase in production of 57 dozens of finished product per workday was obtained, with a balance in the production load of 35%, demonstrating the feasibility of implementing the proposed improvement. The data of the proposed improvement was validated using FlexSim simulation software, corroborating the benefits that would be obtained with the elimination of unnecessary transports and balancing the assembly line in the IMPACTEX corporation's apparel area.
