The research was carried out at the Molecular Immunology Center (CIM), a Cuban biotechnological institution dedicated to basic research, development, and manufacture of products for the treatment of cancer and other autoimmune diseases. The research problem addressed the poor management of inventories in companies, which is largely a consequence of the lack of procedures that enable the good performance of the logistics process. The objective of the research was the implementation of the inventory management procedure aimed at planning, managing, and controlling the necessary inventories without affecting the quality of the services, based on the analysis of indicators, description of logistics flows, and application of the Inventory Reference Model (MRInv). Different techniques and tools—including interviews, direct observation, surveys, documentary analysis, Minitab statistical softw...

In recent decades, Peru has experienced a 2.8% GDP growth, thanks to the gastronomic sector. Engaging in the food business has thus become a robust source of income for the country. Despite this, certain companies face internal issues related to the stocks managed by restaurants, as their staff lacks the necessary knowledge to handle inventory. This results in a 9.7% loss of sales within the sector, while the analyzed company incurs a 17% loss. For this reason, this article has developed a solution to this problem in a rotisserie chicken company, which lacks an inventory management system. Studies pinpoint the cause of stockouts to a poor estimation of consumer demand. However, this study consolidated, in addition to consumer behavior, other factors such as the proper planning of raw material purchases, their quality, the level of service provided by the restaurant, and supplier complian...

The objective of this instrumental study (Ato, López & Benavente, 2013) or psychometric-type (Alarcón, 2008) was to estimate the validity and reliability of the Self-Efficacy Inventory for Multiple Intelligences-Revised (IAMI-R, Pérez & Cupani, 2008) in Peruvian students of fifth year of high school. We worked with a sample of 1304 adolescents, with an average age of 16.81, divided into two groups of 652. Reliability was calculated with the Ordinal Alpha (Contreras & Novoa-Muñoz, 2018) and with the McDonald’s Omega coefficient, obtaining appropriate values. The Exploratory Factor Analysis (AFE) confirms the eight factors of the original version that explain 70% of the variability of the scores. With the confirmatory factorial analysis (CFA), adjustment indices were obtained confirming this factorial structure: SSc2 = 1857.73, gl = 1047, SSc2 / gl = 1.77, RMSEA = .035, S...

The present study explores the psychometric properties of the Parent Perception Inventory (Hazzard et al., 1983), instrument elaborated to describe, with a global approach, the parenting practices just as they are experienced and perceived by the own children. In a sample of 276 students from the 2do to the 6to degree of primary of a private school, the cluster analysis applied confirmed the internal structure of the inventory. On the other hand, the gender of the students as much as the school degree explained little variance in the differences in scores. These differences were, in general, not significant. On the other hand, regarding the psychometric propierties, (1) the analysis supported the validity of the assumed bi-dimensional structure; and (2) the reliability is acceptable.

The present article describes the process of construction of a Family Integration Inventory which contents 52 items distributed in a Likert scale, and has optimum criteria of validity and reliability (α = .739). We obtain a KMO value of .922 which admits the factorization of the instrument As result of the factorial analysis applied in two moments we finally have a unidimensional inventory. Moreover, we settle the percentiles in three levels of family integration: high, medium and low.

Background: In Peru, various instruments have been validated to evaluate variables associated with the family, but until recently there was no psychological test aimed at evaluating the family that had been created in the country. This study presents the psychometric development and applications of the Inventory of Family Integration (IFI) after ten years of construction, and this being the first and only instrument created in Peru that evaluates the family. Method: This research is a theoretical study. Results: It starts first from the review of the theoretical assumptions on which the instrument rests based on the construct of family integration that is inspired by the systemic family approach. Then, the studies carried out on the psychometric properties of the IFI are presented in chronological order, from its construction in 2013 to the recent...

Muchas empresas mayoristas no usan un control adecuado de su nivel de inventario, y variables como la demanda de productos varían continuamente por la estacionalidad y las tendencias del mercado, generando costes que reducen la rentabilidad de la empresa y producen insatisfacción de los clientes con el servicio ofrecido. En este trabajo proponemos la aplicación de un método para reducir el nivel de incertidumbre y riesgo en las ventas y simular la aplicación de una política de revisión continua de inventarios. Utilizando la demanda mensual de la empresa mayorista y considerando la maximización del beneficio, se eligió el modelo de series temporales ARIMA, desarrollado a través del lenguaje de programación R, y luego modelado en el software Arena los resultados de la previsión encontrada. La relevancia del estudio es presentar herramientas de mejora de inventarios que favorezc...

Resource Control Theory (Hawley, 1999) has been presented as an alternative theory for the study of preadolescent social behavior. However, there are no instruments to assess its proposals for the Spanish language. The study’s objective was to validate the Resource Control Resources Inventory for the Chilean preadolescent population. For this purpose, qualitative and quantitative methodologies were used. 5th to 8th graders from two public schools from Santiago de Chile were part of the sample. Seven students were interviewed, and 180 were surveyed. After the translation and adaptation, the inventory showed an excellent fit to the factorial model, and the criterion validity showed similar results to those reported in recent literature.

The objective of this article was to design an inventory control system for a toy store in Puyo, Ecuador. Between November 2018 and February 2019, we characterized the actual situation of inventory management in the company in the first stage of the research; in the second stage, we designed the inventory system. For the analysis and design of the inventory management system of the toy store we combined two procedures, one unrelated to the characterization of the existing inventory system and the other related to inventory planning. We identified that the merchandise in the store was not codified and that the store lacked a storage system for its merchandise. We discovered that the stock available could not be identified. In addition, we determined the inventory parameters as a basis for the design of the automated system. An adequate inventory management will guarantee a timely supply o...
