• MOST AS A TOOL TO SUPPORT THE DEPLOYMENT OF NEW MANUFACTURING PRODUCTS
  ABSTRACT: During the process of choosing a new product, the selection of those that are financially viable and economically profitable is crucial. It is essential to consider as important all the elements that influence the cost of a product. At this point of feasibility analysis, the role of process engineering is to analyze the manufacturing process and to predict, with maximum precision, the time required to manufacture a given product, since the manufacturing time directly influences the value of direct labor cost. The purpose of this research is to use MOST (Maynard Operations Sequence Technique), from Predetermined Motion Time System, to estimate the time required to manufacture a new product. This work, classified as an exploratory case study with qualitative and quantitative analyzes, was developed in a multinational industry of the audio sector located in the Manaus Industrial Pole. The analysis of the new product using image and/or sample served as the basis for the choice of assembly sequence, the first step to be developed for the use of MOST. Afterwards, the indices were applied for each activity performed during the manufacturing and finally the standard time of assembly of the product was calculated. The result of this research shows that through MOST it was possible to estimate the standard time of a new product and obtain the labor cost of R$1.82. Keywords— Maynard Operation Sequence Technique (MOST), Predetermined Motion Time System (PMTS), Standard Time, New product.

• USE OF CLAY SLUDGE WATER TREATMENT PLANT SLUDGE TO PRODUCE CERAMIC BRICK
  ABSTRACT: In the search for solutions capable of minimizing the environmental impacts from waste water treatment plant (WWTP) and reduce costs related to the final destination of the waste generated, the present work aims to evaluate the potential use of WWTP sludge by incorporating clay slurry to the production of bricks, in order to present an alternative environmentally correct destination for this waste. Sludge and clay underwent chemical and mineralogical characterization, through granulometric distribution, X-ray fluorescence analysis, X-ray diffraction. The samples were homogenized in the proportions of 0%, 12%, 14% and 18% of sludge in red clay, pressed at 25 MPa, and later production of test specimens which were then burned to a temperature of 900ºC. After sintering, physical and mechanical tests were performed to evaluate the quality of the final product, by means of analysis of the properties of fire loss, linear retraction, water absorption, apparent specific mass, apparent porosity, flexural rupture stress, moisture and plasticity. The results of the laboratory tests with the residue proportions incorporated in the clay mass demonstrate influence on the physical and mechanical properties of the ceramic material. The results presented show a similarity to that recommended and that despite the 18% (sludge) samples, in relation to the clay showed a variation in the chemical composition due to its high organic matter content, it was observed that both had SiO2, Al2O3 and Fe2O3. Comparing the results with the parameters established in NBR 15270-1, 2 and 3/2005, it was verified that the WWTP sludge can be incorporated in up to 18% in the clay mass for the manufacture of bricks.

• APPLICATION OF REVERSE LOGISTICS IN HOSPITAL MATERIAL PROCESSES: CASE STUDY
  ABSTRACT: One of the major current concerns of society is the environmental issue, precisely because this is a prerogative of great importance for the populations in terms of quality of life. International organizations have sought to develop symposiums, seminars, and global meetings that involve discussions on environmental issues. Since the 1992 ECO-Rio-92 world summit, Brazil has sought to develop a normative framework to foster mechanisms of environmental policies, an element that is already part of the 1988 Constitution of the Federative Republic of Brazil. Thus, this article addresses the Reverse Logistics of Health Services Waste in a public hospital in the city of Manaus-Amazonas, with the general objective of analyzing the reverse logistics process in the recycling of medicine and hospital material in a public hospital in the city of Manaus – Getúlio Vargas University Hospital (HUGV) based on the formation of an inventory of environmental/hospital interests, as well as specifically identifying the main characteristics of reverse logistics; verifying if there is flexibility in the application of the reverse logistics process in the recycling of medicines and hospital material; demonstrating a proposal for the application of reverse logistics to reduce the environmental impact caused by solid waste; understanding how the reverse logistics process can contribute to softening the impact of the environmental degradation caused by the incorrect disposal of medicine and hospital material in a public hospital in Manaus; and, demonstrating its environmental benefits to the city of Manaus. The methodology used included integrative review research, as well as documentary research and direct observation. It is concluded that reverse logistics is a way of obtaining environmental management within the legal parameters determined by the Brazilian legal system but cannot be applied in its entirety in the public hospitals of Manaus, which can make nosocomial disposal dangerous.

• A NEW APPROACH TO ECONOMIC?EMISSION LOAD DISPATCH USING NSGA II. CASE STUDY
  Summary Economic?emission load dispatch optimization problem is an essential task in Q4 power plants with internal combustion engines. In power plants, in addition to electricity, a lot of air pollution by exhaust gases is generated. There are many international standards that establish the permissible limits of different substances but still have not developed an expression to evaluate the environmental impact caused by all components of the exhaust gases as a whole. A new method to evaluate this impact is developed in this paper. The developed mathematical expression was called “emission index.” To get a better idea of the environmental impact of each type of engine, the “specific emission index”, which is the emission index divided by the power delivered by the engine. This paper also presents a mathematical model for a multiobjective optimization of economic?emission load dispatch using nondominated sorting genetic algorithm II.   KEYWORDS: economic emission load dispatch, mathematical methods, NSGA II, power plants
