Optimization of motorcycle assembly processes based on lean manufacturing tools
(Springer, 2020) Quezada Cazorla, Jonnathan David; Sigüenza Guzmán, Lorena Catalina; Llivisaca Villazhañay, Juan Carlos
Global competition and economic dynamism force the assembly industry to look for productive philosophies of improvement, optimizing processes, and resources. The challenge in the optimization process involves finding tools that will grant an optimal process. This article proposes a process optimization through the application of Lean Manufacturing tools, with the necessary guidelines analyzed and verified by computational simulation in a motorcycle assembler. Firstly, applying a plant distribution, together with the change of productive system, allowed the reduction of distances, elimination of unnecessary movements, and reprocessing. Then, Pull System reduced the stock of both the product in process and the final product in the warehouse, avoiding the generation of future waste and expenses due to overproduction. Finally, the use of the 5S tool entailed maintaining order and cleanliness inside the plant to facilitate the management of internal resources. In the study reported, an average reduction of 40% in assembly time and an average increase in production of 30% of all motorcycle models that were part of the study are achieved.
Análisis y diseño de un software de gestión de procesos y costos en empresas de ensamblaje
(2018) Merchán, Eduardo; Sigcha Quezada, Erik Alejandro; Morocho Zurita, Carlos Villie; Cabrera Encalada, Paúl Romeo; Sigüenza Guzmán, Lorena Catalina
The management of strategic processes is primordial to ensure the development of any industry and is especially important given the competitive climate that every business faces while they aim to minimize costs and maximize profits. Unfortunately, the success of it is constantly impacted by internal and external factors, which affects the ability of these processes. The research pursued two primary objectives, it is to advance the knowledge of strategic and cost management processes. First, the article presents the analysis and design of a software that supports cost management and the assembly of processes using the Time Driven Activity Based Costing (TDABC). Secondly, it is argued if the development of the platform would permit to overcome some of the limitations that hindered TDABC over the years. To reach both objectives, the article provides first a theoretical framework that describes the main existing costing systems. Next, the analysis and design of an application using agile methodologies is discussed. The development of the software demonstrates an evolution coming from past experiences and lessons learned with a TDABC prototype that was used for the management of strategic processes in libraries. Further, the discussion section presents an interpretation on the main implications of using the information system as support in cost management and the assembly of processes. The article concludes by summarizing the most important conclusions from the conducted analysis.
A process collection methodology towards TDABC costing optimization of IT services: a case study in an Ecuadorian university
(2019) Ribadeneira Espinoza, Carlos Andrés; Tuapante Vanegas, Tania Lorena; Sigüenza Guzmán, Lorena Catalina; Ayabaca Mogrovejo, Orlando Fabián; Tello Guerrero, Marco Andrés; Vanegas Peña, Paúl Fernando
ICT plays a paramount role in successful organizations. In order to achieve organizational goals, ICT services have to be closely overseen. Tools such as costing methods allow managers to be alert. Implementing a costing method for ICT services not only helps to justify investments, but also optimizes the cost of services. However, methodologies related to providing input to develop a costing model are limited. This research ameliorates ICT service manageMent by proposing a process collection methodology that contributes to the creation of a costing model with TDABC. The proposed methodology has been tested in an IT department in an Ecuadorian University. It matched the collected information with ITIL enabling the department to manage its IT service performance. The obtained processes, activities, times and resources from operative IT services displayed substantive input to design a costing model to improve the IT department and; thereby, the organization’s management as a whole.
Modelo de costeo basado en tiempo invertido por actividad para servicios tecnológicos en Instituciones de Educación Superior: un estudio de caso
(2020) Valdivieso Donoso, Rosana María; Ayabaca Mogrovejo, Orlando Fabián; Sigüenza Guzmán, Lorena Catalina
The Time-Driven Activity-Based Costing, TDABC, is a technique generally used in the production sector that has been adapted to the service setting, such as the health sector and libraries. However, its application in technological services has been little explored. This paper proposes a cost model based on the time-driven activity-based for technological services in Higher Education Institutions, using as a case of study a public university in Ecuador. Where, the resource costs and time of each activity and service were utilized to estimate the costs, per minute and totals of each technological service. The findings highlight the importance of knowing the provision of technological services costs since they allow better financial management and constitute a contribution to the information technology area.

(2020) Arcentales Carrión, Rodrigo Nicanor; Colina Morles, Eliezer Null; Sucozhañay Calle, Dolores Catalina; Durán, Regina; Sigüenza Guzmán, Lorena Catalina
The technological development and continuous changes in economic policies have motivated looking for greater efficiency in all levels of an organization. Organizations include in their management improvements that facilitate the control of their processes and activities. In this sense, management tools for process mapping and modeling have a positive influence on the companies’ performance since their inclusion encourages the improvement and optimization of daily activities. However, there is evidence of disadvantages in the application of some adopted methods. This paper analyzes the weaknesses and strengths of the available management models and tools to cover three specific purposes. Firstly, exploring different tools and models for process mapping and modeling used in business management. Secondly, prioritizing tools that enable their integration with the ISO standard and process costing systems. Finally, establishing the advantages and disadvantages of prioritized tools, as well as their main characteristics. To this end, this work contemplates a theoretical analysis and comparison of the methods Business Process Management (BPM), Business Process Reengineering (BPR), and Event Process Chain (EPC).
A Methodological Framework for Creating Large-Scale Corpus for Natural Language Processing Models
(Springer, 2021) Santos Leon, David Enrique; Auquilla Sangolquí, Andrés Vinicio; Sigüenza Guzmán, Lorena Catalina; Peña Ortega, Mario Patricio; Santos Leon, David Enrique
Currently, there is a boom in introducing Machine Learning models to various aspects of everyday life. A relevant field consists of Natural Language Processing (NLP) that seeks to model human language. A key and basic component for these models to learn properly consists of the data. This article proposes a methodological framework for constructing a large-scale corpus to feed NLP models. The development of this framework emerges from the problem of finding inputs in languages other than English to feed NLP models. With an approach focused on producing a high-quality resource, the construction phases were designed along with the considerations that must be taken. The stages implemented consist of the corpus characterization to be obtained, collecting documents, cleaning, translation, storage, and evaluation. The proposed approach implemented automatic translators to take advantage of the vast amount of English literature and implemented through non-cost libraries. Finally, a case study was developed, resulting in a corpus in Spanish with more than 170,000 documents within a specific domain, i.e., opinions on textile products. Through the evaluations carried out, it is established that the proposed framework can build a large-scale and high-quality corpus.
Transformational leadership and stakeholder management in library change
(Igitur Utrecht Publishing And Archiving Services, 2014-01-01) Sucozhañay Calle, Dolores Catalina; Zhimnay Valverde, Cristian Fabián; Sigüenza Guzmán, Lorena Catalina
This article aims to analyse the role of library managers as change agent when implementing Library 2.0, using transformational leadership and stakeholder management approaches. To do so, a case study in a Latin American academic library was performed. The experiences acquired for a period of six years were analysed, during which three library managers were involved in managing change. Qualitative data from documents, interviews, and observations were collected, and qualitative analysis methods were used to obtain in-depth understanding of the change process. Results show that lack of transformational leadership and stakeholder management contribute to delayed implementation and limited adoption of innovations. Although library managers recognized the importance of different stakeholders to implement changes, they did not apply systematic and proactive strategies to define and manage them. All in all, library managers should be trained as change agents, with emphasis on transformational leadership and stakeholder management skills.
Occupational health and safety for decision-making in the framework of corporate social responsibility: models, guidelines, and indicators
(ICCIS 2020, 2020) Calle Morocho, Byron Fabián; Sigcha Quezada, Erik Alejandro; Guamán Guachichullca, Noé Rodrigo; Sigüenza Guzmán, Lorena Catalina; Calle Morocho, Byron Fabián
Occupational Safety and Health (OSH) is a primary concern in the Corporate Social Responsibility (CSR) discussion since the workers’ welfare is one of the main aspects of operating in a socially responsible manner. When searching for information about OSH management models, a large amount of content is obtained; however, they have not been compiled or synthesized for their analysis. The purpose of this study is to define the main models, guidelines, and indicators that allow building a conceptual framework for decision-making regarding the topic of OSH as a component for CSR. A literature review methodology was applied to select relevant information in the period 2009–2018 about OSH in manufacturing industries. This literature review allowed analyzing a final sample of 96 articles. As a result, this paper identifies the most applied OSH models, their benefits and challenges, as well as the main guidelines and indicators to be included as part of an OSH-based management model.
Decision-making of the university libraries’ digital collection through the publication and citation patterns analysis. A literature review
(Springer International Publishing, 2022) Landívar Ordóñez, Tania Maricela; Rendón Loja, Ronaldo Sebastián; Sigüenza Guzmán, Lorena Catalina
In recent years, different bibliometric methods and indicators, data mining techniques, and collection and visualization tools have been presented to analyze publication patterns and citations of scientific production. Moreover, some criteria and strategies for acquiring bibliographic databases allow forming a knowledge base for decision-making. Unfortunately, these data, methods, and tools are scattered in the literature. In this context, the objective of this article is to determine if the discovery of publication and citation patterns is being used to analyze scientific production in university libraries that helps decision-making on the subscription/acquisition of bibliographic databases. Fink’s methodology was applied in conjunction with the PICO structure for the literature review. This systematic review made it possible to compile relevant information from 167 articles published during the 2016–2020 period into a findings matrix and perform a metadata and content analysis. Among the study’s primary results, it stands out that the analysis of citations, the number of citations, and the VOSviewer collection and visualization tool have been the most outstanding for the study of scientific production. However, it has not had a significant impact as an aid to the acquisition/subscription of bibliographic databases. © 2022, Springer Nature Switzerland AG.

(2020) Llivisaca Villazhañay, Juan Carlos; Jadán Avilés, Diana Carolina; Guamán Guachichullca, Noé Rodrigo; Arcentales Carrión, Rodrigo Nicanor; Peña Ortega, Mario Patricio; Sigüenza Guzmán, Lorena Catalina
A supply chain is a network of interaction between different actors, and indi-cators govern its behavior. The current research deals with the analysis and ranking of critical indicators for the supply chain in small and medium-sized enterprises (SMEs). To this end, firstly, a systematic review of supply chain management indicators for SMEs was carried out. Using data sources such as Scopus, ProQuest, and Google Scholar, 189 metrics were selected. Then, through practical and methodological filters, this number was reduced to 149. To organize these indicators, both models, the Balanced Scorecard (BSC) and the Supply Chain Operations Reference (SCOR-model), were used to connect company strategies to their performance. Secondly, these measures formed part of a questionnaire answered by 30 SME experts. From their responses, critical indicators were evaluated through Principal Component Analysis (PCA), resulting in 50 key indicators. Finally, these indicators were ranked using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). For SCM in SMEs, findings indicate that the primary key perfor-mance indicators (KPIs) are cash flow, satisfaction rate, inventory rotation, and exchange of information through the supply chain.
