The research explored ways for improving maintenance labour productivity and reducing maintenance costs. This can be achieved through reducing the number of maintenance activities and by improving the productivity of labour carrying out repair and maintenance tasks. The research established that Integrated Logistics Support (ILS) techniques, in particular, Failure Modes and Effects Analysis (FMEA) and Reliability Centred Maintenance (RCM) could be applied to building systems, in this case to the maintenance of Rainwater Goods to identify the most applicable and cost effective maintenance strategy. As a result it was found that while 60% of failure modes identified could be rectified by employing a Failure-Based Maintenance strategy, 40% of the failure modes require a Condition-Based Maintenance strategy which is not currently applied. Labour productivity is a subject of tremendous interest to research in the construction industry; the study found however, very little research on the productivity of labour in building repair and maintenance operations. It was found that measurement of building maintenance labour productivity has not been the focus of any previous studies. Indeed no measures of productivity for building maintenance were identified. Having considered a number of alternative measures, the research identified the productivity index expressed in terms of Estimated Hours/Actual hours to be the most appropriate measure of labour productivity in repair and maintenance operations. Using this measure, it was established that labour productivity is impacted by a number of variables including task performance, labour performance, material usage and seasonal variability. Among the objectives of the research was to identify the factors influencing labour productivity. Through a survey questionnaire, it was possible to identify the factors that have the greatest impact on maintenance labour productivity; these were the level of skills and motivation of workmen; quality of information and work instructions; labour turnover and absenteeism; availability of tools and material, and access to the job site. The analysis of historical repairs data from two building repair and maintenance organisations revealed that during the performance of the same tasks, one of the data sources was almost 25% more productive than the other. The research has established that there is a potential for improving labour productivity carrying out building repair and maintenance.

O objetivo do presente trabalho é apresentar uma proposta de sistema computacional para verificação do estado de funcionamento de escadas rolantes por meio de comunicação sem fio. O sistema computacional proposto neste trabalho é composto de uma interface instalada diretamente no painel de controle da escada rolante com o objetivo de coletar informações que permitam identificar o estado de funcionamento desses equipamentos e transmiti-las para um computador remoto por meio de uma estrutura de rede sem fio construída sob o padrão Bluetooth. O sistema proposto possibilita que a inspeção periódica do estado de funcionamento seja feita sem a interrupção do serviço ao público, a qual ocorre somente quando a leitura de dados informar alguma não conformidade ou em períodos pré-estabelecidos pelo fabricante, para troca de peças por fadiga. Dessa forma, possibilita-se um ganho de qualidade e produtividade das equipes de manutenção, as quais poderão realizar uma quantidade maior de inspeções com menor tempo de execução do trabalho e um aumento do tempo de disponibilidade das escadas rolantes aos usuários. O presente trabalho apresenta a arquitetura básica de hardware e software desenvolvidos e discute questões de segurança e confiabilidade do sistema proposto, os ganhos de produtividade para as equipes de manutenção, bem como o aumento do tempo de disponibilidade dos serviços prestados por escadas e esteiras rolantes frente a indicadores mundiais de qualidade de serviço. / The objective of the present work is to present a proposal of computer system for verification of the state of operation of escalator through communication without thread. The computer system proposed in this work it is composed of an interface installed directly in the panel of control of the escalator with the objective of collecting information that allow to identify the state of operation of those equipments and to transmit them for a remote computer through a net structure without thread built under the pattern Bluetooth. The proposed system makes possible that the periodic inspection of the operation state is made without the interruption of the service to the public, which only happens when the reading of data informs some non conformity or in periods established by the manufacturer, for change of pieces for fatigue. In that way, it is made possible a quality earnings and productivity of the maintenance teams, which can accomplish a larger amount of inspections with smaller time of execution of the work and an increase of the time of readiness of the escalator to the users. The present work presents the basic architecture of hardware and software developed and it discusses subjects of safety and reliability of the proposed system, the productivity earnings for the maintenance teams, as well as the increase of the time of readiness of the services rendered by escalator front to world indicators of service quality.

This thesis deals with the productivity of enterprise, the possibilities of its measurement and increasing productivity through the total productive maintenance. The theoretical part firstly focuses on the measuring total productivity in homogeneous and heterogeneous production and calculation of partial productivities of each production factor. Secondly, it deals with the concept of a total productive maintenance as one of the possible approaches to increasing productivity. In the practical part the analysis of productivity for the years 2004 to 2010 is made and evaluated the use of approaches and tools of total productive maintenance in specific enterprise.
