In this paper, we propose an optimization model for medical services processes to reduce waiting time using process mining. In medical services, there is a high percentage of dissatisfaction with medical care due to the processes related to appointment booking and waiting time for medical consultation. As a result, patients change medical services due to the urgency of the symptoms they suffer, generating distrust in health services in Peru. Through a medical information system, events of medical care processes are collected for analysis using the Celonis tool. The process mining discipline uses the discovery of the study process to identify existing bottlenecks in the process and violations that are included when monitoring process events. The proposed model is based on identifying the existing bottlenecks in the processes, which are appointment booking and office care, as these process...

This study develops and empirically validates an integrated conceptual model that investigates the causal relationships among Total Productive Maintenance (TPM), Jidoka, and economic sustainability (ECSU) within the manufacturing industry. Based on Resource and Capability Theory as well as Systems Theory, the model posits that TPM directly influences both jidoka and ECSU, while jidoka acts as a mediator in the relationship between TPM and ECSU. Utilizing structural equation modeling (SEM-PLS) and data collected from 357 surveys of the maquiladora industry in Ciudad Juárez, Mexico, the analysis confirms that TPM positively affects jidoka (β=,632, p<0,001) and ECSU (β=0,340, p<0,001). Furthermore, jidoka contributes significantly to ECSU (β=0,358, p<0,001) and mediates the effect of TPM on ECSU (β=0,226), resulting in an increased total effect of β=0,566. The researchers con...

The construct validity of six hypothesized dimensions was explored for an Accountancy majorgraduation examination, in order to understand the underlying process of responding. Using answers from 313 examinees to an intentional sample of 17 objective items administered on large scale, a confirmatory factorial analysis was carried out, with a Multi-Trait Multi-Method matrix (MTMM): Traits represented three cognitive operations required to solve the items and the methods represented three knowledge fields of the content. Each item was linked to a cog- nitive operation and to a knowledge field. The resulting model showed convergent validity in two constructs and its manifest variables and divergent only between technical and combined knowledge. Thus, the answering process was explained, simultaneously by the Understanding operation influenced by Theoretical knowledge. Implications to...

SMBs have been crucial to the Colombian economy thanks to their contribution to job creation and their positive impact on production. Thus, this research aimed to identify the key categories and variables that influence SMB internationalization, based on the Uppsala model and the theory of dynamic capabilities. The methodology followed was structural equation modeling. The sample included 100 SMBs of the textile-dressmaking sector, geographically located around the city of Medellín, Colombia, in Valle de Aburrá. To define the theoretical relationships, among categories, variables, and hypotheses, was created a path diagram as a strategy to better observe causal relationships between dependent and independent variables. To determine the instrument’s reliability, we analyzed the data using SPSS and then ran the structural equations on the LISREL software. The results allowed us to iden...

Currently biogeochemical models are used to understand and quantify key biogeochemical processes in the ocean. The objective of the present study was to validate predictive ability of a regional configuration of the PISCES biogeochemical model on main biogeochemical variables in Humboldt Current Large Marine Ecosystem (HCLME). The statistical indicators used to evaluate the model were the bias, root-mean-square error, correlation coefficient and, graphically, the Taylor’s diagram. The results showed that the model reproduces the dynamics of the main biogeochemical variables (chlorophyll, dissolved oxygen and nutrients); in particular, the impact of El Niño 1997-1998 in the chlorophyll (decrease) and oxygen minimum zone depth (increase). However, it is necessary to carry out sensitivity studies of the PISCES model with different key parameters values to obtain a more accurate represent...

Today it is difficult for an SME to apply the Quality Models and proposed tests such as CMMI, TMMi,, TMap, IEEE Standard referring to the process of V & V, this primarily by: 1) the degree of complexity,; 2) cost constraints that SMEs do not have enough money to hire market specialists that can provide the directives they need or 3) simply because of the ignorance that exists about the benefits obtained. The present research has as main objective to develop a methodological framework Process Verification and Validation adjusted for socioeconomic reality of SME. The framework was applied to the project Inventory Control System of the Company QBOSS SAC, the initial situation of the company was analyzed, then the methodological framework developed was applied, and finally the results were positive for the organization.

The dehydration processes of onions are governed by a series of kinetic and thermodynamic parameters that, when controlled, facilitate the identification of a mathematical model that will improve the efficiency and quality of the drying process in terms of reducing production costs, environmental sustainability, and the development of innovative products. In this study, various mathematical models were validated to accurately describe the drying process, and from them, the kinetic and thermodynamic parameters governing the dehydration processes were determined. For the experimental development, onions grown in the Ica region of Peru were peeled, cut into pieces, and dehydrated (60, 70, and 80 ºC), and five mathematical models were applied to model the drying kinetics of the process. The Midilli model was the best fit for the experimental curves. Increasing the temperature reduced the en...

Introduction: To establish better approaches to alcoholism, this scale was developed with a focus on cognitive-behavioral aspects. Objective: Considering alcoholism as an issue that requires self-efficacy attention, the scale is designed to guide the psychotherapist in the behavioral change process of the alcoholic patient. Method: This psychometric research, with a non-experimental mixed-method descriptive design, is delineated by a non-probabilistic sampling method that employs structural equation modeling for an infinite sample. Using statistical software, the Aiken's V was obtained from seven expert judges, and 20 items were considered in the exploratory factor analysis for factor loadings (two factors) and factorial weights (λ = 0.62 - λ = 0.94), with Kaiser-Meyer-Olkin and Bartlett's test of sphericity results (KMO = 0.96, p < 0.01). Results: ...

The construction industry has long been suffering from high rates of non-contributory time. Construction processes are likely to include time, which is sometimes lost for non-value-adding operations resulting in time waste. Considering the large percentage of lost time in all operations, this study aims to reduce the high rate of non-contributory time (NCT) in construction services. To test the management model, a Peruvian company was selected as a study case. In this respect, a management model based on mostly implemented Lean tools such as Kanban, 5S, and TPM was utilized. It is of utmost importance to emphasize that this proposal aims to reduce the NCT by up to 25%, as well as reduce the number of orders generated with delay, and eventually reduce the loss or damage of materials and equipment stoppages.

As processes become more complex, measuring them using key KPI indicators, such as Overall Equipment Effectiveness (OEE), is essential. This study analyses the OEE of the cardboard box production process-the product with the highest annual revenue in a Peruvian printing company. The current OEE is 64.27%, which falls short of the graphic industry standard (72.5%). Increasing the OEE would provide several benefits, such as higher availability, improved product quality, reduced setup times, and lower machine wear. Therefore, an innovative solution model is proposed that will use SMED and TPM tools, as well as Automation and IoT technologies. These Lean tools will be enhanced through the mentioned technologies. The solution model will follow the PMBOK approach due to its significant contributions to project management and will consist of three phases: initial, implementation, and closure. I...
