Faced with such issues, some research have proposed solutions to improve the results in software project management in order to contribute significantly to its success. The objective of this paper is to carry out a study of the context of software project management, identifying the management areas that have been intervened with gamification strategies for software process improvement. To this end, this work proposes a systematic mapping as a research method that facilitates the identification of primary studies to analyze information and classify it based on established research criteria. We found 55 primary studies published between 2011 and 2017, on which we performed an information analysis. This analysis highlights the increase in the number of studies that use gamification as an improvement strategy for software project management processes areas. We classified the selected studies by analyzing the type of research method and the type of publication. This analysis shows that it is still an area of research in development and that it is necessary to continue working on the improvement of software project management processes with the aim of contributing to the success of its results.","PeriodicalId":347825,"journal":{"name":"2018 13th Iberian Conference on Information Systems and Technologies (CISTI)","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124323854","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 aims to explore the potential of time series prediction algorithms in an IT company. The forecast was based on the company's billing data for 192 months of activity. The analysis of the data was based on the Cross Industry Standard Process for Data Mining approach and for the treatment; we used the Anaconda IPython and Pandas. We developed the prediction with three models using R: Exponential Smoothing (Holt-Winters), autoregressive integrated moving average (ARIMA) and artificial neural networks (ANN). The comparison of the performance of each of the methods shows that the model based on artificial neural networks has a greater accuracy in the prediction. These results need deepening the study to broaden the universe of the studied contexts. However, the simplicity in the application of the artificial neural networks model makes possible its use in computer applications without specific knowledge, giving a reliable instrument that allows the supporting decision-making by managers.","PeriodicalId":347825,"journal":{"name":"2018 13th Iberian Conference on Information Systems and Technologies (CISTI)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122044179","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 development of the system is subject to the regulation 005/14 established by the ARCONEL Electricity Regulation and Control Agency, realizing a real time monitoring of the condition and operation of the lamps, alerting when the lighting service presents problems due to faults. In this way, the proposed system will optimize the resources of the institution regardless of the lighting technology used, generating reports for decision making to improve the service and in case of unexpected or interruptions of service, coordinate maintenance activities that solve the problems immediately.","PeriodicalId":347825,"journal":{"name":"2018 13th Iberian Conference on Information Systems and Technologies (CISTI)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124489282","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 the first method, the algorithm is used: Discrete Transformation of Decimal Wavelet (TWD decimated) or Mallat Algorithm. The Value is obtained from the MULT. Then applying the fusion to the Value and PAN component through the TWD decimated daubechies (db4) generates a new Value (nval-m). With the nuance and saturation of the MULT image, the inverse HSV-RGB transformation is performed to generate a new multispectral image (N-MULT1). In the second methodology, the algorithm is used: Discrete Wavelet Transform not decimated (TWD not decimated) or Algorithm of À trous, applying the fusion to the Value component and PAN through the TWD not decimated generates a new Value (nval-a) and with the nuance and saturation of the MULT image the inverse HSV-RGB transform is made to generate a new multispectral image (N-MULT2). Finally, the results of the two methods are presented using the ERGAS, RASE and Qu indices for assessment. It is obtained that the à trous method is better spatially and spectrally.","PeriodicalId":347825,"journal":{"name":"2018 13th Iberian Conference on Information Systems and Technologies (CISTI)","volume":"2001 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128298722","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}
