In humanity there are several people with visual impairment, thus calling this condition to the total or partial loss of sight. In the research carried out, the ergonomic design of a device that is integrated by 4 writing, reading, traction and printing systems is presented. The design of the device was made through 3 phases, the first corresponds to the design process of the systems mentioned above, the second to the ergonomic design of the device and control and the last to the integration process of all the systems described above. With the development of this design is intended to benefit people who have visual impairment by helping them to the process of their learning and also develop in these people various communication skills, with this device is intended to facilitate reading and writing with the Braille system for people with this disability and in the same way provide them with a more ergonomic and easy to use design.

Time is considered a fundamental element in any type of industry, which is why it is necessary to improve it, companies that cannot improve their processes through the reduction of waiting times or downtime, problems of serious damage to their operation daily. The company under study presents serious problems in the panel line, for example, laminated sheets, poor cutting, spillage of coating, paper tear, for the operation of this line there is an available time of 48 hours, it is important note that only 71% of the time is productive. The objective of this study is to implement an ANDON system, through the identification of problems that affect production, in order to reduce response times on the Panel Line. ANDON is a visual and auditory communication system used in the industry that allows workers to interact in a simple way to solve problems that arise during the workday when they occur (Vera, 2018). This project contributes to the continuous improvement of the panel line, as well as a change in the work philosophy of the operators.

The SLP method (Systematic Layout Planning), is an organized technique for planning a distribution, made up of four phases, in a series of procedures to identify, evaluate and visualize the elements and areas to be distributed. The following case study proposes a new installation of Mathfer Services based on the SLP methodology for the optimization of resources with an efficient and safe handling of electrical materials, considering the dimensions and characteristics of the projects, through macrolocation and microlocation, the selection of equipment for handling raw materials and electrical supplies, the analysis and representation of the interaction of activities, the determination of spaces and general distribution, ending with the design and detailed presentation of the new installation of Mathfer Services through AutoCAD software and the presentation of the renderings of the modeling of the installation in the SketchUp software. Emphasizing that the design of an installation is not exclusive to the manufacturing industry, it is applicable to all types of spaces, as in this case, services.

In the management of the production, SMED (acronym of Single-Minute Exchange of Die) derived from the Lean Manufacturing methodology can be interpreted as a philosophy of work born in Toyota, its application is based on the elimination of waste in a sustainable way over time, allowing improve the productivity. This research presents the application of the SMED methodology in a company specialized in the production of honeycomb type packaging, where the main problem is in the line of CHS, this produces the main component of the product, however, the delay time is up to 71 minutes per model change, adjustment of the machine and then the start, reflecting in 1500 pounds of delayed product, being affected in customer response times, generating overtime and not meeting the daily production goals. The objective of this research is to reduce the time of preparation and assembly of the tooling according to the requested changes, through the application of SMED a flexible production system will be obtained that allows responding to the constant changes in the market, reduction of delivery times and increase in production capacity.
