Small and medium-sized enterprises have always proven to be crucial to national economies, yet many of them fail for a variety of reasons. One of them is selecting an inadequate supplier that does not meet the needs that the company requires to properly perform its core business. Therefore, this project proposes to develop a web application to select the best supplier option for a company. The main objective is to assist in decision making and reduce costs with a web application that implements the Fuzzy Analytic Hierarchy Process (FAHP), based on a series of criteria and priorities chosen by the company itself. After testing the application, the result was a relative score assigned to each alternative, thus identifying the supplier with the highest value as the most optimal choice. Finally, through the measurement of the consistency ratio for each pair matrix developed, it was possible ...

In current supply chains, the use of AIDC technologies allows the information that flows to be standardized and reliable, as well as obtaining a series of advantages related to saving time and costs. In Cuba, the use of these technologies is not regulated by national laws and most companies do not use them, considering ignorance of their effectiveness as the cause. This article analyzes AIDC technologies: specifically, bar code systems and radio frequency systems, their operation and benefits of their use in supply chains. Based on the existing need, a tool was designed based on a procedure that establishes a guide for the selection of technologies to be implemented in logistics processes. The tool designed is used for Case Studies to know its application and mode of use.

The present article proposes to design a model that provides a generic architecture which acts autonomously in public works contracting selection processes, in order to generate an automated decision criterion in the event of a tie. For the Simplified Tender selection process, in case of a tie, it is proposed to choose the bidder by means of an electronic lottery based on a controlled randomization system of encryption and transformation. For the Public Bidding selection process, in the event of a tie, the bidder is chosen by means of a predicted compliance index according to the behavior of the companies when executing similar infrastructure projects. To this end, a model that predicts the probability of success or failure of the bidder to execute a project before initiating it is generated, using artificial neural networks as an analysis tool. This paper reviews the common characterist...

More than a year ago, Ecuador suffered a 7.8 Mw earthquake that was devastating, the automatic response was to run to the affected areas and rebuild. Meche’s House is an alternative: the crisis as an opportunity to experiment and consolidate popular construction systems based on an endogenous and holistic approach. This study evaluates two case studies and their contrasting methodologies in their process of selecting beneficiaries for post-disaster reconstruction: Casa Lista of Mutualista Pichincha and La Casa de Meche, differentiating both cases from analyzing their different approaches: the automatic one, non-reflective and product-based, the other analytical and process-based. Founded on experience and how different processes need different beneficiaries, this study will raise some questions about the effectiveness, pros, cons, and perspectives of different approaches to right...

This work proposes an electronic equipment aimed at measuring the color difference between fabrics for a homogeneous selection of these. The proposed method analyzes tissues with different illuminants so that, by taking measurements with a camera, the impact of effects such as metamerism can be reduced, resulting in a more accurate method that represents reality. For this, an enclosure was designed and built to allow constant lighting conditions and spotlights with standard lighting were installed. On the software side, the camera was manually configured to ensure persistent measurements over time and the colors obtained from the RGB color space were converted to CIELAB. For the calculation of the color difference, the Delta E (CMC) color difference equation was used because this is the standard used in the textile industry. Finally, a neural network was trained to estimate the color dif...

Gas sensors are fundamental for continuous online monitoring of volatile organic com-pounds. Gas sensors based on semiconductor materials have demonstrated to be highly competitive, but are generally made of expensive materials and operate at high temperatures, which are draw-backs of these technologies. Herein is described a novel ethanol sensor for room temperature (25◦C) measurements based on hematite (α-Fe2O3 )/silver nanoparticles. The AgNPs were shown to increase the oxide semiconductor charge carrier density, but especially to enhance the ethanol adsorption rate boosting the selectivity and sensitivity, thus allowing quantification of ethanol vapor in 2–35 mg L−1 range with an excellent linear relationship. In addition, the α-Fe2O3/Ag 3.0 wt% nanocomposite is cheap, and easy to make and process, imparting high perspectives for real applications in breath analyzers and/or s...

Nowadays, the construction industry has become the main and great engine of the global economic recovery after the effects of covid-19, generating around 10.7 trillion dollars worldwide, and it is residential construction, specifically, the one in charge of driving growth in the short term, thanks to the constant demand for residential spaces. In this sense, various challenges such as new technologies, the complexity of projects, and a growing competitive environment, force the main contractor to subcontract between 80 and 90% of the activities, thus evidencing that subcontracting is an applied and necessary process in every construction project, and making subcontractors the backbone of the procurement strategy. However, one of the main risks of subcontracting is the inadequate selection of the construction subcontractor, which is often based solely on the criteria of selecting the know...

The present work reports the successful synthesis of a novel Pb2+ ion-imprinted polymer (Pb-IIP) based on a rhodizonate-like selective ligand by precipitation. Three functional monomers, namely acid acrylic (ACRY), 2-acrylamido-2-methylpropane sulfonic acid (AMPSA) and allylamine (ALLY), were chosen by computer simulation using density functional theory (DFT). The materials obtained were applied for the selective removal of Pb2+ from aqueous solutions and were characterized by Fourier transform Infra-red (FTIR), scanning electronic microscopy (SEM) and flame atomic absorption spectrometry (FAAS). The results obtained from the adsorption experiments performed under optimal conditions were in good agreement with the computational design and showed that IIP-AMPSA exhibited a relatively higher adsorption capacity for Pb2+ (51.84 mg g?1) than IIP–ACRY (31.02 mg g?1) and IIP-ALLY (12.90 mg g...

Abstract– Micro, small and medium-sized enterprises (MSMEs) represent 90% of the companies incorporated in the world, their importance is such that they generate between 60% and 70% of employment and 50% of GDP; the Peruvian case is not different from this context since MSMEs generate 85% of employment and contribute 84% of GDP. These companies develop their productive and commercial activity in different economic sectors, including textiles and clothing; This sector, which represents 7.2% of the gross domestic product (GDP), concentrates approximately 700,000 workers and has been growing at average rates of 40% in recent years. However, despite the dynamism and importance of this sector, productivity is extremely low; This is due to different factors, one of these being human capital management; this factor is related to the deficient processes of selection, hiring and training of per...

The selection process of design team subcontractors by real estate companies is crucial in construction projects, directly affecting the quality and efficiency of the final results. However, the lack of time to evaluate potential subcontractors can lead to inadequate selection and negatively impact the project development. This study proposes an innovative approach to improve confidence in the selection processes of design team subcontractors in multifamily building projects by implementing Set Based Design (SBD) and Choosing by Advantages (CBA) methodologies. These methodologies, supported by Excel Macros programming and data visualization in Power BI, aim to automate and optimize the selection process, reducing human intervention. The study follows these steps: (1) information registration and analysis by experts, (2) determination of the conventional subcontract selection process in t...
