This study presents an application of the Tornqvist Index and the markup pricing method to find the market price opportunity for airfares and one of the specific objectives is to present a methodology for comparing the financial results of airports based on ANAC Resolution No. 350/14, which allows a 100% increase in aeronautical charges concerning the tariff ceiling. To predict passenger demand with new airport fares, the least-squares method was used based on empirical equations and the concept of elasticity. The scenario used was the Campinas / Viracopos Airport from January 2014 to March 2017. The results showed that it is possible to increase the price of the domestic aeronautical charges and the revenue from the airport, with the counterpoint of falling demand. This method, based on cost and market opportunity, but on which the financial statement should be audited, is shown to be promising to increase airport revenue.","PeriodicalId":35415,"journal":{"name":"Gestao e Producao","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67159503","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}

This study examines similar and different views about secrecy within three executive levels of an industrial multinational organization named Motores. This is achieved through a case study for which the data has been collected by using a survey-like questionnaire and semi-structured interviews. The different maturity levels and process structures in the enterprise account not only for different stages, concerns, and types of knowledge involved in addressing secrecy, but also for the role boundaries among the agents surveyed. Furthermore, while these agents are well acquainted with suppliers and customers, whereby confidentiality is ensured through confidentiality agreements (NDAs) and patent protection, their relationships with institutions and organizations appear to be areas of little or no knowledge, especially when it concerns competitors, class entities, and government relations. Leaks of classified information occur, and the places and situations where they may take place are identified. No potential mitigation situations were identified in our case study, and no systemic protocol exists for dealing with classified topics in the different areas where secrecy is involved, including business strategies. Transparency is recognized and desired; however, its risks and consequences require evaluation.","PeriodicalId":35415,"journal":{"name":"Gestao e Producao","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67159947","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}

However, there is a lack of studies analyzing employment and income over time, especially comparing the agricultural activities. Our major argument is the structural change in the employment - from un-skilled to skilled workers which has to be understood because of the overall decrease in the number of jobs. This study aims to analyze the labor market evolution in sugarcane farming and other agricultural activities, from 1992 to 2015. Using the National Household Sample Survey (PNAD/IBGE), we compared sugarcane and other Brazilian crops using econometrics techniques. We analyzed the Heckman's procedure and models with fixed effects panel data, controlling the unobservable characteristics of workers. Methodologically, our equations show convergence, since the Heckman procedure and pooled regression present similar estimates. We showed that fixed-effect regression captures the same trends of Ordinary Least Square (OLS) technique, using the Heckman method. Our main findings suggest that the wage of sugarcane workers is higher than wages in other crops, even after we control the observable and regional characteristics. This finding is important because the sugarcane sector has faced criticism regarding the low level of employment and income due to the mechanization process. Finally, we pointed out the decrease in unskilled jobs in sugarcane, which demands for policy intervention to improve the human capital in the sugarcane sector.","PeriodicalId":35415,"journal":{"name":"Gestao e Producao","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67160256","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}

This study creates a model to analyze CSF in civil construction project management, using Artificial Neural Networks (ANNs). For that, a literature review was performed to identify CSF emphasizing project management. Once the CSF were identified, a questionnaire was sent to educational institutions to evaluate the effect of each factor. Response analysis was made by the Relative Importance Index, using ANN coupled with the resilient propagation algorithm to evaluate the CSF. A total of 37,822 articles were found in 2,328 journals. Of 874 e-mails sent, 191 were answered. The respondents were distributed in 26 Brazilian states, with 70% of them being professors/researchers, 26% coordinators, 2% Rector, and 1% Director/Manager. Weights were determined using the Garson algorithm. The most critical factor in project management was ‘Unrealistic inspection and test methods in the contract’. Artificial Neural Networks produce subsidies to know the relevance of the input variables adopted and constitute an effective means for modeling nonlinear variables.","PeriodicalId":35415,"journal":{"name":"Gestao e Producao","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67160704","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}

In this context, the present study applied the Autonomous Maintenance pillar (AM) of the Total Productive Maintenance tool (TPM) in an unusual context. The AM is used to involve the various actors of the company in the conservation of equipment with the aim of improving their performance concerning a reduction of failures and an availability and reliability increase. In the present study, the AM had the objetive of mitigating the generation of waste in the production of a women's shoes industry, installed in a Local Productive Agglomeration (LPA). This APL is composed mostly of micro and small enterprises (MPE) that do not have the culture to using maintenance tools, but in its process generate hazardous waste. It is important to highlight that this kind of company does not typically use the concepts of industrial maintenance. In conclusion, with the implementation of the AM pillar, it was possible to reduce the volume of waste generated in the cutting sector, contrary to the fact that the company does not use the concepts of industrial maintenance in its strategic decisions, thus opening up new strategic possibilities for discussing the use of widely disseminated tools in some areas for other purposes.","PeriodicalId":35415,"journal":{"name":"Gestao e Producao","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67159905","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 present study aims to investigate and analyze waste by making-do in seven companies from Goiás with the aid of a Dashboard and perform the risk analysis of the identified waste. Data were analyzed during the technical visits at each site, among which the direct non-participant observation, questionnaire application and document analysis stand out. The analysis of the data indicated that most of the waste is related to the steps of sealing and structure within the construction sites, in particular, for components connected to plastering and concreting. The main impact was rework, followed by reduced security. With the risk analysis, the main points were identified according to their severity, thus guiding management decision making. As final contributions, the main impacts and suggestions for their minimization are presented. Therefore, we highlight the need to use reality and information technology tools in future works for integrated production control and to assist in the identification of waste by making-do in construction sites.","PeriodicalId":35415,"journal":{"name":"Gestao e Producao","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67160673","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}
