Improving the teaching and learning process of engineering is one of the critical aspects for developing countries. The objective of this project is to analyze the learning performance in the engineering classes of the School of Engineering of Coquimbo (EIC), Universidad Católica del Norte (UCN), Chile. The methodological design is based on Data Envelopment Analysis (DEA) and applied to aspects related to the learning performance of students and teaching. The data from 70 classes of the first semester of 2022 was collected from UCN's educational system database. Based on the DEA methodology and factors related to learning performance, we expect to make recommendations and suggestions based on the results, implying that the UCN, but also engineering courses around the world, can improve aspects related to the classes.","PeriodicalId":413394,"journal":{"name":"International Joint Conference on Industrial Engineering and Operations Management Proceedings","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126301369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Strategic Thinking and Mental Models: Comparison Between Brazilian and Spanish Students - Implications for the Teaching-Learning Process","authors":"F. Bressan","doi":"10.14488/ijcieom2023_full_0041_37707","DOIUrl":"https://doi.org/10.14488/ijcieom2023_full_0041_37707","url":null,"abstract":". In this business environment characterized by VUCA, strategic thinking (ST) is mandatory for the company's strategic objectives accomplishment. ST competence is related to neurocognitive functioning, that is, to the mental model (MM), which can be Operational Mental Model (OMM) or Strategic Mental Model (SMM), which is more conducive to Strategic thinking. Many students report difficulty in dealing with strategic issues and prefer disciplines that are more operational and focused on the present. This difficulty results from their preferences for an operational MM having the focus on the here and now. Instead of the Strategic MM linked to ST. This paper presents survey results of undergraduate students’ Mental Models at UNICAMP (Brazil) and UPC (Barcelona), analyzes the incidence of the MM conducive to strategic thinking, and presents a comparative analysis between them. It discusses the relationship between the ST and the MM and its relations with the teaching and learning process. It concludes that the MM may be one of the causes of students' difficulty with the ST demands and proposes alternatives for developing the SMM.","PeriodicalId":413394,"journal":{"name":"International Joint Conference on Industrial Engineering and Operations Management Proceedings","volume":"430 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126095853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Making HIV pre-exposure prophylaxis (PrEP) easily accessible to adolescents requires enabling and strategic recruitment and linkage to PrEP services. The PrEP1519 project is a single-arm, demonstration cohort study of daily oral antiretrovirals as PrEP among adolescent men who have sex with men (AMSM) and transgender women (ATGW) aged 15-19 years old in Brazil. The objective was to apply and analyze operational strategies in recruitment methods for prospecting adolescents in the context of social vulnerability. Participants were recruited by trained peer educators who engage with youth at gatherings, venues, events, and schools; through online social media and mobile apps. The data were collected between 2019-2020 in Salvador, Brazil. Based on a literature review, statistical methods were used to apply decision-making and operations management methods to direct recruitment strategies. Gender identity ( p= 0.006) and sexual orientation ( p= 0.007) were significantly relevant to recruitment meth-ods. Even without a large Pearson relationship, the construction of the cross-tab-ulation for the other variables facilitated decision-making to direct recruitment resources. Well-trained youth peer educators effectively recruit aMSH and aTGW for PrEP. However, recruiting needs direction for consistent decision-making to rethink or reinvent strategies or new paths when a strategy reaches its limit.","PeriodicalId":413394,"journal":{"name":"International Joint Conference on Industrial Engineering and Operations Management Proceedings","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122454358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

V","doi":"10.14488/ijcieom2023_abst_0044_37747","DOIUrl":"https://doi.org/10.14488/ijcieom2023_abst_0044_37747","url":null,"abstract":". Railroad networks are capital intensive operations that involve interaction between thousands of dynamic entities for e.g. trains, passengers, etc. while constrained by a fixed set of limited resources such as tracks, trains and platforms. Mathematical programming models have been used to allocate and operate resources efficiently and effectively but are applied separately at various levels of the decision making hierarchy namely, operational, tactical and strategic. While the individual considerations of the models at the different levels of decision making may be different (for example, the time horizons and problems addressed), decisions made at various levels affect each other due to common constraints originating from the static nature of the railroad topology, long lead times to add resources, etc. Further, real-time operational disruptions provide feedback that should be incorporated back into the tactical and strategic decision models to improve the model’s performance. One limitation of the current decision models is their stand-alone development with minimal interaction and feedback between decision levels. For e.g., time tables generated using customer demand form constraints for real-time operational planning. Separate treatment of long term strategic decisions and tactical models and modelling them in isolated fashion reduces its practical utility as interactions between these levels are ignored. We show interdependent nature of decision-making at various levels by bringing out the interplay between inter-level model constraints and variables.","PeriodicalId":413394,"journal":{"name":"International Joint Conference on Industrial Engineering and Operations Management Proceedings","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115802658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transition to a low-carbon economy necessarily involves the implementation of large-scale electricity generation from Renewable Energy (RE) sources [1], which now account for around 30% of electricity generation in the world [2]. In this context, developing countries will play a key role as they present the best environmental conditions for generating electricity through RE sources and have the highest rate of growth in demand for electricity [3]. Wind and solar generation have consolidated their predominance in current investments so that electricity from RE sources is now the cheapest power option in most regions of the world [4]. Given the current high fossil fuel prices, renewable electricity has become even more competitive [5]. RE sources are fast becoming the cornerstone of the global electricity sector. In a carbon-neutral economy scenario for 2050, the share of RE sources in electricity generation will correspond to approximately 90%, with almost 70% of electricity being from wind and solar photovoltaic energy. However, several countries will face limitations to their solar photovoltaic energy generation potential due to land area restrictions [6]. In this way, wind energy will gain even more relevance in some countries, such as European ones, which will have to implement other sources of clean energy [7]. Due to the complexity and high capital costs involved in large-scale wind power generation projects, the economic analysis of these investments becomes fundamental, indicating the need to use management and risk analysis tools to reduce the possible impacts for investors [8]. Indeed, finding a suitable investment strategy is central to determining success in wind farm investments. Identifying the main characteristics in the previous studies, such as the technology adopted, the region or country studied, and the methods and financial criteria adopted in the studies, can serve as guidelines for researchers, investors, and other stakeholders interested in this type of technology.

Performance measurement (PM) in small and medium-sized enterprises (SMEs) is increasingly a space of crucial scientific contribution, not only because of the evidence of practical actions aligned to strategic planning but also due to the need to formalize and structure methodologies for the implementation of performance measurement systems in specific contexts. Assessing global research activity based on a bibliometric analysis helps position researchers regarding PM development in SMEs. 335 records extracted from the SCOPUS database were processed in VOSviewer (graphic visualization tool used). The primary analyses were the co-occurrence of keywords, publications, annual citations, countries, and most representative authors. Those analyses led to the recognition of foremost exponents, and critical themes around the proposed article, such as performance, sustainability, and innovation, have registered an increase in related research since 2019 and mainly in the region from Asia.","PeriodicalId":413394,"journal":{"name":"International Joint Conference on Industrial Engineering and Operations Management Proceedings","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124448099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sustainable development and carbon dioxide emissions have been debated in the oil and gas sector as a basis for developing plans to reduce the emission of this gas in its operations, influenced by the commitments made in the Paris Agreement by reducing the emission of greenhouse gases (GHG). Investment funds demand organisations act on this subject, urging companies to outline GHG emissions throughout their value chain. This work aims to contribute to including initiatives to decarbonise the construction phase of infrastructure capital projects using the procurement process. Through a systematic literature review (SLR) and a case study applied to a Brazilian oil and gas company, the documentation related to four contract opportunities for the construction of infrastructure and offsite areas was evaluated, applying criteria raised in the literature to identify initiatives that lead to the decarbonisation during the construction phase. The study comprised interviews with experienced professionals and direct observation of the procurement process preparation of two projects. Results showed initiatives as contractual requirements targeting energy efficiency, minimising costs, and maximising productivity associated with using GHG-emitting equipment. We deliver a strategic guide for incorporating environmental sustainability initiatives with a focus on reducing GHG emissions into the processes for procuring construction services and assembling logistics infrastructure and offsite projects.","PeriodicalId":413394,"journal":{"name":"International Joint Conference on Industrial Engineering and Operations Management Proceedings","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133979809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
