Hiring processes are intended to recruit and retain ideal candidates; those who would generate competitive value in an organization. In an increasingly global context, the challenge is often costly, inefficient, and complex. Even though artificial intelligence already solves specific tasks with greater speed, precision, and efficiency in various fields, and in different companies, in the area of human resources the desirability of the use of data science continues to be debated. By reviewing cases and research, in which the integration of artificial intelligence applications in the selection processes was tested, measuring and socializing impacts, I contribute to the current discussion aimed at overcoming the mistrust that exists by default, and that is associated with the ethical challenges and risks t assumed to solve a human problem through technology. I conclude that it is possible t...

In this work, a torque controller for a variable rotational speed wind turbine has been modelled using Reinforcement Learning and considering the Optimal Torque - Maximum Power Point Tracking problem as one of optimization. The reward optimization function is designed as a non-linear function depending mainly on the rotor power variation. Based on this, an optimal action (electromagnetic torque variation) regulates the turbine rotational speed. A simulated 1.5 MW three bladed wind turbine operation is managed by the torque controller. It keeps the turbine working at optimal operational conditions after a successful training process, which is carried out using the Proximal Policy Optimization algorithm. For the controller training, the turbine confronts constant and then randomly staggered wind speed behaviour. Time series of rotor angular speed, torque and power are presented. Our result...

Many construction companies worldwide continue to implement different methodologies to optimize time and improve management in the execution of works; however, a lack of control in projects continues to be observed. For this reason, one of the most common problems currently is the incompletion of scheduled work. Due to this, it is necessary to keep better control of the projects at the execution stage so that the contractor can optimally, quickly, and easily manage the progress of all the specialties involved. In this sense, this research develops the use of the Plan Grid Application for data collection in the field and the Power Bi software for the automatic processing and information visualization through a management dashboard where indicators are shown to reflect the progress and actual performance of the activities as well as the main non-compliance causes, which leads to optimize t...

The sample that is the subject of study is a concentrate mainly of gold pyrite, product of the flotation process, from Empresa Minera Aurífera Calpa S.A. The characterization of the concentrate in the UNMSM polarized light microscope shows the presence of pyrite, sphalerite, chalcopyrite, electrum, marcasite, pyrrhotite, arsenopyrite, rutile and gangue. In the polished briquette corresponding to the +100 mesh, the presence of electrum has been observed. In the scanning electron microscope at the University, the presence of gold particles has been observed, even in pyrite; Said particles have sizes smaller than 200 nanometers, particles of gold and silver telluride intertwined with the electrum are also observed, whose particles have sizes smaller than 2 microns. These characteristics make the concentrate refractory to conventional treatment by the cyanidation process, which constitutes ...

People with upper extremity disabilities often face significant challenges when attempting to book medical appointments through conventional online booking systems. These barriers can hinder their ability to access essential healthcare services in a timely manner. To address this problem, this research focuses on the development of an innovative medical appointment booking system that uses voice interaction, complemented by a chatbot interface, to improve the user experience for people with upper extremity disabilities. As a result, a marked improvement in medical appointment booking times was achieved, increasing satisfaction and compliance levels among all users.

At the Cajamarquilla zinc refinery, the cooling systems of cooling towers No. 1 (160 K and tower tech) and No. 2 (320K) as any cooling system present problems of corrosion, incrustation, accumulation of impurities and microorganisms Which are in contact with water quality from other areas, such as roasting, sulfuric acid plant, hydrometallurgy, among others. With the research carried out, clean and modern technologies were applied to optimize the operation of the cooling towers, which made possible a better quality of the liquid effluent and the reduction of water use from the purges of these refrigeration systems that are treated and Discharged to the sewage network, then discharged to the “Poza de Retención” and finally to the “Poza de Regantes” located to the south of the Cajamarquilla refinery owned by the irrigation association of the “Jicamarca” valley.In this sense, t...

The plant layout problem can be generalized as a case intensively studied combinatorial optimization and therefore its nature is a NP- hard. The core of the problem originally introduced as the Systematic Distribution Planning , a multi -criteria and relatively simple, has been extended to larger contexts , through the formulation as a mathematical model based on the nature of the workshops . Given the computational complexity of the calculations have been developed heuristics ,metaheuristics and others to obtain approximate solutions . The aim of this study is to analyze recent research on plant distribution problems within the industrial context by classifying and comparing the representation of the problem , solution methods , constraints and the objective function used . The report covers more than 30 peer-reviewed articles on the subject. Particular attention is placed on recent pub...

The present article develops a number of classical economic-financial applications in continuous time based on the software Stella (Isee Systems, Inc.). The problems under analysis basically deal with modeling projected free cash flows and investments, and their Net Present Value estimation, a process which in many cases may require numerical integration. The document shows how Stella allows construction of a model in a simple fashion, and with it to make simulations that give graphical solutions, as is the case of the decision of the optimal harvest time, or the selection between alternative projects, among others.

Humans are at the heart of crucial processes in warehouses. Besides the common economic goal of minimising cycle times, we therefore add in this paper the human well-being goal of minimising workers’ discomfort in the context of order picking. We propose a methodology for identifying the most suitable storage location solutions with respect to both goals. The first step in our methodology is to build data-driven empirical models for estimating cycle times and workers’ discomfort. The second step of the methodology entails the use of these empirically grounded models to formulate a bi-objective assignment problem for assigning products to storage locations. The developed methodology is subsequently tested on two actual warehouses. The results of these practical tests show that clear trade-offs exist and that optimising only for discomfort can be costly in terms of cycle time. Based on...

The construction sector is searching for new technologies, such as drones, that prove helpful for the surveillance and supervision of construction sites, especially in pandemic situations. This research proposes designing flight planning models to optimize flight time and speed. The main objective is to develop a model that allows multiple drones to carry out supervision tasks in construction areas. In this regard, it presents a dynamic programming model and a metaheuristic based on genetic algorithms, both applied for optimizing flight plans with multiple drones. The development process involves planning the route that the drones will follow by formulating the problem with the corresponding parameters. The next step is to generate a model for the dynamic programming algorithm, which is then validated using a genetic algorithm. The proposals implemented in Python were tested in 14 scenar...
