The objective of this study is to propose Lean Manufacturing tools to optimize the fresh cheese production process at the microenterprise “Productos Lácteos Marlen.” The study was prompted by the existence of operational waste that affects the performance of the production system, particularly unnecessary movements, unproductive transport, activities with no added value, and imbalances in the distribution of work; which limit the microenterprise’s efficiency and productivity. The process diagnosis was carried out using tools such as Value Stream Mapping (VSM), the analytical diagram, time and motion studies, and production capacity analysis, which allowed for the identification of the main problems within the production chain. On this basis, improvement opportunities were identified aimed at optimizing the workflow, reducing downtime, and improving the use of operational resources. Based on the results obtained, Lean Manufacturing tools such as 5S, standardized work, and visual control were selected, enabling the formulation of proposals focused on the organization of workspaces, the elimination of unnecessary activities, the standardization of procedures, and the strengthening of control. The proposed approach optimized the organization and continuity of the production process, reducing unnecessary activities and improving the utilization of operational resources. Furthermore, the results show that the implementation of Lean Manufacturing tools enhances efficiency, quality, and continuous improvement in the production of fresh cheese.

This research was carried out at the ALME car body company, located in the city of Ambato, which specializes in the manufacture and repair of bus bodies. The purpose of the study was to propose Lean Manufacturing tools to improve the process of lining metal structures. These strategies were compiled in a manual with the objective of reducing the waste identified in the process and, in this way, contribute to the optimization of the production process of lining. For the development of this project, a comprehensive analysis of the company's current situation was carried out, which allowed us to identify the different areas of work, as well as the activities carried out in them. The study is specifically focused on the lining process, for which information was collected on the existing sub-processes. Subsequently, a time study was carried out and the main types of waste or muda were identified, such as: unnecessary movements accounting for 43.7% of the total, reprocessing accounting for 35.2%, transport accounting for 15.5%, and waiting accounting for 5.6%. These data were used to draw up the current VSM, which provided information on the initial state of the plant. Through a root cause analysis, opportunities for improvement were identified for each type of waste found. This process was complemented by a literature review focused on the advantages and benefits of each methodology, allowing for their subsequent selection. Improvement proposals were then developed, choosing three tools, resulting in the following conclusions: for rework waste, the best methodology is POKA YOKE or “zero defects”; for motios and transport, the best option is the 5S methodology, and for waiting times, the KANBAN tool.

This research project is based on proposing a distribution of facilities with a lean approach in the company Elohimtex Cia Ltda. The consideration of an efficient distribution makes the performance of the organization count with an improvement in productivity and optimization of resources. For the development of the proposal, the application of two strategic approaches, the SLP methodology and manufacturing cells, is approached. The techniques considered within the parameters of lean manufacturing are the value stream map, to analyze the current and proposed state; and Kanban cards that allow efficient control within production; each tool is intended to replace activities that do not generate value to the product to be developed and eliminate possible waste. To contemplate how beneficial the stipulated proposal could be, a simulation was carried out using FlexSim. When comparing the results of the current situation with the proposal, a 32% reduction in distance traveled is estimated. With these data identified through the simulation, it is evident that the proposal considered has important benefits within the elaboration of products in the organization, making that the processing times have a significant reduction.

The lean manufacturing methodology is an excellent way to reduce waste by identifying, measuring and controlling it. Several companies have made use of this methodology that encompasses all those involved in the processes of an organization, generating as a product an organized and standardized culture. The Municipal slaughterhouse of Ambato, dedicated to the slaughter of large and small cattle, has seen the convenience of improving its processes in relation to existing waste, time in its processes, standardization of its activities. The objective of this research project is to propose improvement proposals through the application of tools belonging to the lean manufacturing methodology to mitigate or eliminate waste related to this methodology such as: unnecessary transports and movements, waiting times, defects, over-processing, within the processes of cattle slaughtering. For which a collection of information of the current slaughtering processes is developed with the help of industrial engineering tools, thus knowing which are the activities, tools, machines, personnel and current documentation used. Additionally, by means of a time study, the standard time of each of the processes was obtained as well as their respective cursograms and plant layout. These times are used for the development of the current VSM, with which the waste and activities that really add value in the production process can be identified in order to subsequently establish the most critical waste through a Pareto diagram with the use of tools such as the 5'S used to maintain order, cleanliness and discipline; TPM to maintain the equipment and tools in an optimal state to avoid plant stoppages and defects. To reduce the time of some critical processes, activities such as knife affiliation were eliminated and the proposal to acquire a pneumatic skinning machine was also made, reducing the slaughter time per bovine from 8.77 min to 6.01 min. Likewise, for traceability, improvements have been proposed in the activities, developing a process diagram for the same.
