Avaliação para identificação de pré requisitos ausentes em perdas por making-do na construção civil

Abstract

The construction industry can be considered one of the driving forces of the Brazilian economy. This market currently faces problems such as high interest rates, tax burden, bureaucracy and high labor costs. In this context, the concepts of Production Engineering help to overcome this challenge. Concepts such as management of production systems that focus on developing solutions and improvements for the corporate environment when applied in conjunction with Civil Engineering are extremely beneficial to the sector. The planning, execution and control of operational flows and their processes within the construction industry ensure that the cost of productivity is achieved with the minimum of available resources. Although there are several studies that address the management of production systems, the literature shows a lack of applications aimed at the construction industry, in order to highlight the wastes when service packages are started or continued without the presence of the complete kit, that is, without the resources necessary for their execution. In view of these issues, this dissertation aims to develop an applied research, with the main theme being wastes due to improvisation or wastes due to making-do in the construction industry. Aiming to meet the requirements necessary for the final product, a requirement for approval in the Postgraduate Program in Production Engineering - PPGEP at UFG (PPGEP, FCT UFG, 2024), it is structured in the format of a collection of articles. The first article sought, through a systematic review of the literature, to support the theoretical framework of the research by establishing the line of reasoning that would make it possible to define which are the good management and planning practices applicable to civil construction and in which phases of planning these solutions are applied. The second article presents the method used in the collection and classification of data. As partial results of the research, it presented the analyses related to the correlations between the classifications of wastes due to making-do in the universe investigated. The third article presented a multi-criteria decision-making model and how it is applied in order to assist managers in decision-making when determining a management solution that best impacts the guarantee of the prerequisite of the planned activities, thus anticipating decisions to reduce the occurrence of wastes due to making-do by determining informal packages. The results showed that the good practices identified in the literature can be considered as facilitating activities of the process, being important to reduce the occurrence of improvisations. The proposed model proved to be a robust and effective approach for decision making, with the development of the model that combines the Fuzzydelphi and TOPSIS techniques standing out as a contribution of the study, using linguisticterms to evaluate the weights of the decision makers and the criteria
