Present article gives continuity to the elaboration of the infotercio financial model proposed as an alternative to implementing environmental management systems in governmental institutions based on the emission reduction of printed reports, source codes and forms originated from IT activities. It discusses procedures of green IT certification for managers and governmental institutions derived from ISO 14000 family and People CMM, combining both in a new set of requirements. Also it summarizes the reasons for such a certification system, noting that waste paper is now a major global problem, not only in terms of direct environmental impacts but from the point of view of the unreasonable and unnecessary use of paper in governmental business processes, generating high costs, mismanagements and time losses, at the same time causing reduction in the available physical space in corporate environments and increase in fuel consumption for transport. © IFIP International Federation for Information Processing 2014.

Maintenance shares significant operating costs in an organisation. It is considered as a main pillar of the organisational performance. Lean thinking can be incorporated into maintenance activities through applying its principles and practices. Lean maintenance is a prerequisite for lean manufacturing systems. The exhaustive literature review has been conducted to collect the up-to-date maintenance strategies and activities, lean principles and practices in the lean maintenance process. The scope of this paper includes eight types of waste (non-value added maintenance activities), maintenance value stream mapping and a scheme of lean maintenance practices. The output of this paper is a proposed roadmap to apply lean thinking in a maintenance process. © 2015 The Authors

In the search for renewable energy sources, solar energy appears, among others, as a powerful alternative;mainly for those countries located at Earth’s equatorial region. This is the case of a Fresnel device that uses solar radiation to warm-up the air;for instance, within saunas. Authors coined the term sustainable technological innovation to refer to a technological innovation in accordance to the principles of sustainability. The object of this research was comparing the sustainability of a Fresnel Lens Solar Concentration (FLSC) against the sustainability of other twelve alternatives to generate heat. This article assesses the sustainability of fourteen technological options for heat generation and transfer to saunas in the northwest region of Mexico where temperatures often reach above 45 C and where there is a greater potential for exploiting solar energy. Emergy accounting, economic analysis, and global warming potential are the three indicators considered in quantifying sustainability. Results show that infrared ceramic photovoltaic, infrared carbon photovoltaic and infrared metal photovoltaic are the most sustainable systems. The Fresnel device reached the fourth and tenth position, using electricity from photovoltaic and from grid respectively, among all fourteen assessed devices, respectively. Although Fresnel equipment does not release any global warming gases into the atmosphere, or even it demands low amount of non-renewable resources, 1.40 and 4.47 E17 seJF/yr. it requires high economic investment, 20,800 and 79,600 USD/yr, for the implementation and operation phases, which decrease its sustainability performance compared to twelve other evaluated devices.

Modeling to Relate Variables in the Context of Franchises in Brazil

引用

Latin American Business Review 2015年第1期16卷 23-43页

作者： Siluk, Julio Cezar Mairesse Neuenfeldt Júnior, Alvaro Luiz Production Engineering Post-Graduation Program Federal University of Santa Maria Santa Maria Brazil

The central objective of the research is to propose a model for the comparative study of the degree of relationship between the variables considered as most relevant in the context of franchises in Brazil. In terms of methodology, the research undertook a qualitative survey of the variables, which in a second phase provided a quantitative framework in order to fulfill the proposed objective, through concepts based on multicriteria methods, performance measurement systems, and linear correlation. Resulting from the practical implementation proposed for the General Food category, it was found that only two constants, denoted “Average Initial Investment” and “Financial Obligations,” are directly related to the base variable defined by “Gross Revenues.” © 2015, Taylor & Francis Group, LLC.

This paper presents and compares two different DEA models used to evaluate the efficiency of Brazilian Olympic Confederations in using the financial funds (from the Agnelo/Piva Law in 2011) e transform them into results, that is, medals. We use two different models, in both models the funds coming from the Agnelo/Piva Law distributed in 2011 is considered as an input, in order to evaluate how efficiently these funds were being converted into results by each one. The main difference between these two models is how each one of them used the data related to the number of gold medals offered by each sport in 2011 Guadalajara Pan American Games and also the data related to the number of gold, silver and bronze medals won by each sport during this same competition. The number of gold medals offered represent a proxy for difficulty measure in winning a medal. The first model considered these data as a second input and the number of gold, silver and bronze medals won by each sport were considered as outputs. The second model used only the funds received by each Confederation as an input and it used three outputs, which were formed by a ratio of the first model's output to the number of gold medals offered by each sport. After comparing these models, the results obtained by each one of them are presented and discussed in order to determine the best approach to perform an efficiency evaluation of Olympic sports.

The technological development in healthcare experienced in actual days has relationship with the integration of many knowledge areas, fundamentally by searching new solutions in order to improve the quality of life of the society. Examples of this reality appears in medicine and engineering areas, where the computer-assisted techniques works together to solve many healthcare problems. In the surgical procedures context as well, as in dental implant planning, the surgeon still determine some parameters according to his personal experience, where only the visualization of the problems through Computed Tomography images are not enough to ensure the success of the procedure. Thus, this research aims to propose a computational model, as a decision support tool, in order to define a more appropriate positioning for dental implants. This is a fundamental part to determination of the necessary parameters for the process planning because the information is obtained automatically straight from image processing. The prototype presented in this work comprises a user-friendly interface, which allows dentists to observe the bone and dental structure in multi-perspective images. Also, it determines the implant location by an automatic procedure without intervention of dentist. The text shows a study case with the autonomous determination of an implant position.

International Journal of Manufacturing Research 2015年第3期10卷 267-285页

作者： Simon, Alexandre Tadeu Lima, Carlos Roberto Camello Production Engineering Graduate Program UNIMEP - Methodist University of Piracicaba Rod. Luis Ometto Santa Bárbara d'Oeste SP13451-900 Brazil

Computer numerical control (CNC) technology has received high level of investment around the world. Considering machine tool for machining operations, almost one third of those installed in Brazilian industrial companies is composed of CNC machines. About 46% of them are less than ten years old and belong to a generation of machine tools that should have a higher density of automation, incorporating features and advanced production techniques that suppose efficient management. However, there is a low rate of utilisation of available resources, such as tool presetting, in-process measurement systems and automatic load and unload to reduce idle time. Additionally, there is a reduced use of techniques to achieve higher maximum cutting speeds and longer tool life. There is also a low rate of use of low environmental-impact techniques such as dry machining, and a very low percentage of companies that treat and reuse cutting oil.

In this paper, we present an application of the Paraconsistent Artificial Neural Network (PANnet) in a Statistical Process Control to trigger alarms in an electrical power System. The PANnet is based on Paraconsistent Annotated Logic (PAL) which is a non-classical logic with properties of accepting contradictions in their fundamentals. In this work, we make a joint application technique of Paraconsistent Annotated logic, in the form of PANnet, with the concepts of Statistical Process Control (SPC). The Statistical Process Control Paraconsistent (SCP-PAL) is used in this paper to make a dynamic monitoring of the conditions of the electrical voltage in an electrical power system. To test and validate the functioning of SPC-PAL Controller we use data obtained by random computational processes and we also use a database with actual values generated by a power electrical System of a company installed in Brazil. The SPC-PAL Controller, due to the use of the algorithms of PAL in its construction, has some features that does afford optimized electrical voltage monitoring. The result of the analysis made with the SPC-PAL Controller provides three types of alarms: 1) rapid Variation in the voltage;2) Imbalance of Mean in the Voltage data;3) High dispersion index in the voltage data. Based on these three types of alarms we can obtain a better understanding about the operating state of the electrical power system. In the various tests performed, the SPC-PAL Controller presented a good performance and detected changes in Mean and in the variation of tension, as well as sudden changes in voltage data. © 2015 IEEE.
