Currently, the textile and clothing industry contributes 2% to the global annual GDP and generates more than 57 million jobs worldwide. In South America, a country with a high market share in the textile sector in Peru, whose industry is the objective of this research due to its lack of studies in the accessory sector of clothing. Musculoskeletal disorders are the most common and leading cause of injury and disability in workers and in the clothing industry; it is due to the handling of materials that involve machinery with a high rate of repetition of work by operators. This article aims to reduce the percentage of Musculoskeletal Disorders (MSDs) by redesigning workstations and using combined ergonomic tools together with Lean tools so that, in addition to giving focus to workers, a different way can be found to add value to the process and improve productivity. A 71.85% decrease in MSDs was achieved in the sewing and cutting area, as well as a decrease in absenteeism by 20.73%, along with savings of S /. 505.72 per year.
The research was carried out and executed in Peru, in the company Escalabs, the effect of the gray water recovery and reuse system on water saving was determined, in the execution of the thesis a non-experimental, descriptive cross-sectional design was used. With non-probabilistic sampling by expert judgment. The data collection was done with the technique of systematic observation of non-participant type, to analyze the data descriptive statistics were used, the problem is that in the face of the worrisome panorama of water scarcity that worsens with time, the reuse of gray water represents a good opportunity to optimize its water use, in this research the effect that the system of recovery and reuse of gray water has on water saving in a bathroom of the company Escalabs was analyzed, where it was determined that a saving of 14. 20% in water consumption, with an economic benefit of 1.23 nuevos soles per month, demonstrating a positive effect on water savings and a positive economic balance.
The present research was carried out in Peru, comparing the budget of the multifamily project of a construction company with BIM and traditional methodology, for the realization of the article a non-experimental, descriptive design was used, considering as population and sample a multifamily project of Constructora Galilea with traditional and BIM methodology, data collection was carried out through the documentary review technique, the instrument used was the matrix of categories, to analyze the data used descriptive statistics, the problem arises from the budget of the multifamily project of Constructora Galilea which was prepared using traditional methodologies to be compared with the same budget but prepared using the BIM methodology in order to exploit its benefits such as the optimization of resources and costs, the budget prepared using the traditional methodology resulted in a total of S/. 1,238,541.36 while the budget elaborated using the BIM methodology was S/. 1,096,844.25, it was possible to compare the budget of the multifamily project of the Galilea construction company with BIM and traditional methodologies resulting in an optimization of 11.44% in costs in favor of the BIM methodology.
This article was carried out in the Larco Oval located at the intersection of South America and Victor Larco Avenues, in the city of Trujillo-Peru, with the objective of analyzing the microsimulation of traffic and vehicular congestion in the area. A descriptive non-experimental design was used, where the technique used for data collection was direct observation, with record cards and video cameras; the data analysis process was carried out through the construction of a microsimulation model with Vissim software, which allowed calculating performance indicators of the intersection. The microsimulation process yielded values related to travel time, which through calibration was estimated as an accurate representation of the existing situation through the model; thus, the vehicular congestion analyzed with the HCM 2010 methodology and the vehicular microsimulation obtained a high level of saturation,resulting in a level of service F that proves the supply-demand gap in the infrastructure. Therefore, the geometric design of a turbo traffic circle was proposed, which, following the same evaluation process, caused an important congestion relief up to a level of service D.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
