Acceptance Sampling of Vegetables and Legumes in Units Based on the Military Standard (MIL-STD 105E)

2024 , Villacís Guerrero, Jacqueline del Pilar , Álvarez-Duque W. , Bonilla-Villacís J.R. , Avilés-Castillo F.

A low-quality batch brings with its adverse effects on the productivity and profitability of a product. The Military Standard (MIL-STD 105E) allows calculating the acceptance number for an attribute sampling plan under regular inspection with an acceptable quality level. This study is carried out in the national distribution center (CND) of one of the largest supermarket chains in Ecuador. There is a lack of quality control in the reception of essential products and processes carried out empirically. Ensure the quality and safety of vegetables and legumes that are received daily. Develop specific instructions for sampling vegetables and legumes in units based on MIL-STD 105E. When conducting a verification audit, an increase of 15.93% in compliance with the standard technical ARCSA-DE-067-2015-GGG was obtained. Food product reception, processing, and distribution must follow strict biosafety and quality protocols. This proposal provides business opportunities for improvement and standardized handling of documentation and processes, which other similar institutions can use. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Residential Water Consumption Monitoring System Using IoT and MQTT Communication

2022 , Villacís Guerrero, Jacqueline del Pilar , Cunalata-Paredes, D.Y. , Bonilla-Villacís, J.R. , Soria, A. , Avilés-Castillo, F.

Water shortage across the globe causes changes in the life of the human being, not to mention that water is a resource that must be preserved for future generations. The companies that distribute and charge fees for residential water services have problems performing the periodical manual readings. Thus, showcasing inaccuracy in the costumer statements at the end of every month. The following paper describes the development process of a low-cost intelligent control and monitoring system of residential water consumption. The system design uses a flow sensor that measures the influx of liquid as it passes through the pipes. Based on the value that the conventional meter marks at the beginning of the day, it is possible to determine the daily consumption. The processing of acquired data is performed with a low-cost controller (SBC). Also, the respective control actions were transmitted towards a solenoid valve, which controls the passage of water to the house. Next, an access and communication point is established applying bidirectional MQTT (Message Queue Telemetry Transport) protocol to send and receive data wirelessly through Internet of Things (IoT). Data was stored and managed on a local server. The prototype displays information through an LCD screen and in a web page. To achieve this, the server sends information such as date-time, username, meter number, etc. The results showcase that the measurements were performed as expected. Thus, validating the possibility of using it in a larger sample. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Implementation of a Quality Management System According to ISO 9001:2015: The Case of a Textile Company

2024 , Buele, Jorge , Villacís Guerrero, Jacqueline del Pilar , Tierra-Arévalo M.L. , Tierra-Arévalo J.

This textile company is dedicated to the industrial washing, drying, and dyeing of garments, according to the indications of its customers. The global economic recession and many competitors have caused the top management to decide to implement a quality management system, which allows it to better manage its resources and thus provide a better service. Therefore, the implementation of a system based on the requirements established by the UNE-EN ISO 9001:2015 standard is proposed. The starting point is the initial analysis of the organization’s context, identification of stakeholders, risks, and opportunities, which allows redefining internal processes. The development of a complete documentary structure allows a better organization of the activities performed by the processes and their interactions. To validate the system, an internal audit is carried out, verifying the degree of compliance with the requirements. With the active participation of all the personnel and with the top management as a leader, there is an improvement in the efficiency of the company, establishing a reference for other organizations in the sector. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
