Item Acesso aberto (Open Access) Compressão tempo-custo paramétrica ótima de projetos de construção civil(Universidade Federal do Pará, 2012-08-30) BENTES, Jayme; ICHIHARA, Jorge de Araújo; http://lattes.cnpq.br/5726366418302065One of the issues of the Civil Construction Industry is around the planning phase of the the project, when is possible to verify the difficulty in completing the project in time, initially, thinking as the contractor. Therefore, the present study proposes the application of the linear programming method as a solution to the problem of the optimization of the factors time and costs from the Civil Construction projects. Initially it was done, by bibliographic mapping, also as the re-reading of some basic concepts, programming Technics with network and critical path. Afterword, it was discussed definitions of operational research and mathematical models of Linear Programming. It was proposed, therefore, a method aiming the solution of the issue of the time optimization and projects expenses of Civil Construction. To demonstrate the application of the proposed method, it was used as a scenario, a governmental construction project, that the goal was the compression of the project in 14 days, reaching a period of contract, a cost of compression the amount of R$ 95,040.15 (ninety five thousand forty dollars and fifteen cents), less than if there were an increase in penalty for delay. With this achieved our objective, compression project for the desired duration.Item Acesso aberto (Open Access) Estratégia de competição empresarial na construção civil paraense da Copala Industrias Reunidas S/A(Universidade Federal do Pará, 2004-09-01) RUFFEIL JUNIOR, Simão Massud; ICHIHARA, Jorge de Araújo; http://lattes.cnpq.br/5726366418302065This dissertation is based on the analysis of competitive strategy adopted in the market of iron bar for civil construction in Belém, capital of Pará, by COPALA INDUSTRIAS REUNIDAS S/A. So, there is interest in evaluate the possibilities of the company in the sense o f staying actuating with success in the sector, in which weighs the contestant carried out by metallurgies of great deportment, of which interests are from national and international encompassing. Search were realized considering the steel market of de civil construction of an ample way, being consulted constructors, businessmen and consumers of that material. Like wise, the proper COPALA was object of evaluation as well as acquirer of raw material to the steel manufacture, as how producer and seller of the product .Item Acesso aberto (Open Access) Jogo de empresas para administração e controle de custos: um modelo para empresas fornecedoras de componentes para a construção civil(Universidade Federal do Pará, 2006-12-20) DIAS SOBRINHO, Aderivaldo Cabral; ICHIHARA, Jorge de Araújo; http://lattes.cnpq.br/5726366418302065This work presents a model of business game aiming at to take care of the managers of supplying companies of components for the civil construction, characterized by exercise of all the functions, with difficulties to understand and use economic and financial information presents on the reports, as well as promoting the theoretical and practical nip of these information to the academic community of Engineering. For the development of the business game was necessary , beyond of the recognition of some supplying companies of components for the civil construction, a countable study of concepts and techniques, in that it refers to the Accounting of Costs and Managemental. The business game was applied in the academic environment of the Federal University of Pará, together with the students of Civil Engineering, to this, the students had to pass for a process of conceptual leveling and knowledge of the dynamics of the business game, and in a micro company, Proativa, in Belém. The results had confirmed the advantages of the use of the enterprise simulation presents in this work in the process teach-learning.Item Acesso aberto (Open Access) Modelo de mudança organizacional: estudo de caso no setor de compras(Universidade Federal do Pará, 2013-10-04) FERNANDES, Lucas Athayde; http://lattes.cnpq.br/5726366418302065; ICHIHARA, Jorge de Araújo; DUARTE, André Augusto Azevedo Montenegro; http://lattes.cnpq.br/1135221873341973This paper presents a model of organizational change to improve the business process purchases from the communication system between the Central Office and works at construction company, to identify opportunities and deficiencies in the system is a technological and / or management. The mapping of information to detect unnecessary pathways that prevent communication system operating in an agile and optimized as well as realize opportunities for continuous improvements to the process. The research method was based on the improvement of business processes, which consists in modeling the process mentioned, through data collection, analysis documents, design flow of information existing in the model and discussion of results. For validation of the method, it was the single case study in a construction of buildings subsector, which generated flowcharts purchasing process current and proposed as a model of organizational change.Item Acesso aberto (Open Access) Modelo de simulação computacional para balanceamento de linhas de produção das empresas cerâmicas de São Miguel do Guamá: um estudo de caso(Universidade Federal do Pará, 2013-10-16) SILVA, Denilson Costa da; ICHIHARA, Jorge de Araújo; http://lattes.cnpq.br/5726366418302065This work is to present a computer simulation model for the purpose of solving the problem of balancing production lines of a factory belonging to the polo red ceramic potter-ceramic São Miguel of Guama. In this sense, it is initially performed a literature search on the discrete event systems, the methods of solution for line balancing and concepts involving the modeling and simulation. The methodology addresses the case study, which is conducted by the method proposed by Chwif (1999) in which covers three (03) macros stages in conducting a simulation project, whether the stage of design, implementation and analysis stage. With the computational model developed based on the current characteristics of the production line, one can describe the current state of the process, identify the problem operation as well as forward proposals for improvements from the construction of 03 scenarios. Where the third scenario presented the best results and, therefore, being the representative model of the balancing. At the end, it is understood as the main contributions of this work even bringing into the university experience of the practical application of simulation involving a ceramic industry of São Miguel of Guama and offer the industry of this region a potential tool for improving their processes productive.Item Acesso aberto (Open Access) Qualidades intrínsecas para inovação de produtos em piso e revestimento de cerâmica vermelha do APL de São Miguel do Guamá(Universidade Federal do Pará, 2008) MENDES, Adriana de Nazaré Moraes Mendes de; ICHIHARA, Jorge de Araújo; http://lattes.cnpq.br/5726366418302065This dissertation represents a contribution in solving the problem of innovation of products in the red ceramic industry in São Miguel do Guamá, state of Pará. It is a methodology, based on the strategy of QFD (Quality Function Deployment) which combines the requirements of consumers in the preparation of the product designs and production processes. The lack of knowledge of products or services to be sold is a major (and obvious) reasons for the failure of small retailers and services. In the current level of competitiveness, information is the key to business success and adapt to the market, not only to obtain and collect this information, but also to learn to interpret them and use them properly and in a creative way. The product quality is assessed both in terms of internal (technical) and the external aspect (quality required by customers). Research shows, in addition to the living reality of the industry of ceramics industries, the importance and attributes of quality defined by consumers on the red tiles. The work also shows the application of a methodology for companies in the sector through unfolding of the required quality, the quality is down planned.Item Acesso aberto (Open Access) Utilização da opção de diferimento na avaliação de implantação de projeto de mecanismo de desenvolvimento limpo em uma empresa de cerâmica vermelha(Universidade Federal do Pará, 2009-09-25) NEGRÃO, Léony Luis Lopes; ICHIHARA, Jorge de Araújo; http://lattes.cnpq.br/5726366418302065The evolution of the theory of option pricing considers a set of tools to manage and exploit the value arising from the uncertainty and volatility that expand the parameters of the value-adding to the concepts of managerial flexibility. Within this context, this study was to evaluate the implementation of economically Clean Development Mechanism in a red ceramic company located in Production Arrangement of Bindure, northeastern Para The evaluation aims to demonstrate the value of managerial flexibility of Deferral adjustments made according to the methodology proposed by Copeland & Antikarov (2001), which adds to the traditional evaluation of the discounted cash flow Real Option – OR – that the research found, and it is based by means of literature review to formulate the method. This follows a determination of the essential steps for the analysis of the variables that comprise the model, and has allowed the ordering of the results for the values of the OR considered including value present and managerial flexibility, with the method the company object of research. Finally, as a result of this study concluded that the Theory of Real Options through Option Deferral or Postponement contribute information to assist in management decisions to invest in projects when compared to traditional methods of evaluation are considered as uncertainties inherent in the project as the real environment.
