The purpose of this research is to conduct a time and motion study and subsequently propose improvements for the productive processes in the unwinding area of Arboriente S.A., a company located in the Pastaza province dedicated to the manufacturing and commercialization of plywood panels. The research begins with the collection of information about the company, a detailed description of the productive processes, and an initial diagnosis conducted in the unwinding area through non-structured interviews with area supervisors. To achieve this, process recording sheets, analytical flowcharts, and route diagrams were employed, facilitating the identification of the work method used in each activity. Subsequently, a time and motion study with corresponding analyses was conducted for each subprocess, determining the cycle time and production capacity. It was identified that there are excessive distances between work zones for material supply or waste collection, and it was observed that the debarking of logs in the Peeler and the unwinding process of logs in the Cremona Lathe have longer cycle times. As an improvement proposal, a redesign of the work zones for the storage and selection of logs is suggested, resulting in substantial improvements in efficiency, achieving a 25.87% saving in unproductive distances. Additionally, a new work methodology is proposed to eliminate unproductive activities and reduce idle times, leading to a percentage increase in the production capacity of the peeling machine and the Cremona lathe by 19.74% and 17.84%, respectively. Finally, a procedures manual was developed to instruct operators on the appropriate work method for standardizing their activities.

Process standardization encompasses the elimination of activities that do not add value to the product in order to obtain a different perspective on resource management in terms of reducing costs and proposing an adequate circular economy. The study presented a process standardization model in the production of the textile company BOMAN SPORT S.A., following circular economy guidelines. The problem derived from the excessive consumption of resources present in the production plant due to the lack of regulation on the activities carried out in the workplace. Through the ABC analysis, the study on the professional t-shirt (product with the highest demand) was proposed, which has the processes of design, cutting, sublimation, ironing assembly, printing, seam control and packaging. During the time study it was identified that the company used 3284.01 s. to make a garment. Through the changes used, a standard time of 3045,76 s. was obtained, improving the daily capacity by 3 extra units. The circular economy guidelines embodied in the procedures manual were directly related to environmental awareness, the most relevant aspects were that: the fabric (raw material) resulting from the cutting process can be recycled to recover part of the economic expenses and contribute to the reduction of the impact generated by waste; all failures produced during the assembly, stamping and sublimation processes can be avoided through equipment calibration and stability of the activities and; The impact generated by water treatment can be reduced by regulating the pressure output from the industrial iron.

In the research project the study of times and movements in the dairy company “The Swarm” is carried out in order to improve the production process, increase productivity and standardize the process. The current situation of the company is known through direct observation and unstructured interviews with the manager and the operator in charge of the production area. From the initial diagnosis of the company, the ABC analysis is performed to select the product of greatest demand using the sales history, identifying mozzarella cheese as the product of greatest consumption to carry out the study. To obtain the necessary data for the development of the project, time measurements were made by timing, taking into account the activities and movements performed by the operator in each subprocess; the information obtained is organized by means of flowcharts, analytical cursograms and tables. During the development of the project, the bottleneck and the absence of standardized processes were identified. Finally, the standard times of each subprocess are determined and activities that do not generate value were eliminated or combined, obtaining an improvement in time of 4.08% and from this the line balance is carried out to balance the workloads and that the process flows continuously; additional the manual of procedures for the production of mozzarella cheese was developed to guide the workers in the development of their activities and therefore improve the productivity of the company.

The purpose of this research work was improve the productivity of the company Calzado KF Barona, developing a study of times and movements in the process of manufacturing men's casual footwear. Through this study, time wastes and excessive transports have been identified due to a bad distribution of the production process and that is why a plant redistribution proposal has been made using the SLP methodology in order to establish a chain production that benefits the company by improving its productivity. Therefore, it is important to highlight the steps for the development of the research, which begins with the collection of information of the company and the current production processes within it, using tools such as flowcharts and flowcharts to recognize the activities that are performed in each area; it continues with the taking of times and movements of these activities within each area, identifying the bottleneck and excessive travel times that harm the company. From this, a plant redistribution is proposed through the SLP methodology that reduces these time wastes, organizing correctly the work areas and allowing a better flow of material. Reducing in more than 70% the transports, optimizing the processes, achieving an increase of the production in 88 pairs per month and raising the production capacity in 8.4%, which reflects the improvement of the productivity allowing gains of $880 per month in monetary values.

The footwear industry exposes a limited control of production processes, causing deficiencies in the verification of methods, materials and operating time, which causes performance losses related to labour and machinery, this problem is not different for Ralma footwear for this reason the research aims to develop a study of times and movements that will increase the production of the company. For which, the study uses a quantitative approach with a descriptive research, starting with the identification of the production areas, followed by the timing of operation time and detailing the movements carried out during the manufacture of footwear, defining the standard time of each operation through the use of the manual of work study practices, the scales of valuation of the rhythm of work and the system of supplements dictated by the ILO. The results show that it takes 520.63 minutes and 157.71 metres to manufacture a batch of 10 pairs of shoes, indicating the existence of dispensable and unnecessary activities that take place in the processes in the 5 production areas. Therefore, it is concluded that there is a need to implement a new method linked to combining or eliminating operations and inspections with the aim of eliminating transports and waiting times, implementing new equipment and instrument arrangements to reduce production time in each work area and increase the company's productivity.

La investigación se enfoca en el análisis de la capacidad física de trabajo (CFT) de los operarios de la empresa de calzado BOOM'S para establecer valores óptimos del límite del gasto energético en una jornada de trabajo de ocho horas, para evitar disconfort y fatiga por la inadecuada distribución de las actividades. Se analiza las operaciones del área de montaje y se establece el tiempo estándar de cada operación; con esto, y mediante tablas de estimación de metabolismo a partir de los componentes de la actividad se calcula el consumo metabólico de las operaciones. Además se evalúa la CFT de cada operario y se calcula el límite energético de los trabajadores para una jornada y se establece un programa de acondicionamiento físico. Asimismo se redistribuye las actividades realizadas por los empleados evitando que se sobrepase los valores del límite energético. Los resultados obtenidos evidencian que las operaciones que requieren un consumo elevado de energía son: el armado de talones con 6.40 Kcal/min, descalzado de horma con 6.12 Kcal/min y plantado de suela con 5.38 Kcal/min. La CFT para el 75% de la población se califica como alta y para el 25% como normal, además se establece un valor de límite energético de 5 Kcal/min para todos los trabajadores y con la propuesta de la nueva distribución de las actividades en el área de montaje, el gasto energético de la jornada para cada operario es igual o menor a 4.07 Kcal/min con lo que se garantiza que no existe un sobreesfuerzo en las actividades laborales. ABSTRACT The research focuses on the analysis of the physical work capacity (CFT) of the workers of the BOOM 'S shoes company to establish optimal values of the limit of energy expenditure for a working day of eight hours, to avoid discomfort and fatigue due to inadequate distribution of activities. Operations of the mounting area are analyzed and the standard time of each operation is established; with this, and by metabolism estimation tables from the components of the metabolic activity of operations consumption is calculated. Also, it evaluates CFT and calculate power limit for a working day and the fitness program is established for each worker. The activities of the employees are redistributed to avoid exceeding limit values power limit. The results show that operations requiring high power consumption are reinforced heel with 6.40 Kcal/min, barefoot in last with 6.12 Kcal/min and planted sole with 5.38 Kcal/min. The CFT for 75 % of the population is classified as high and 25% as normal, well worth the energy limit of 5 kcal/min for all workers and the proposed new distribution of activities set out in the mounting area, energy expenditure of the day for each worker is equal to or less than 4.07 Kcal/min then It ensures that there is no exertion at work activities.
