(2011) Factors influencing the quality of maintenance and their impact on product and services offered by Tanzanian industries, Master dissertation, University of Dar es Salaamhttp://41.86.178.5:8080/xmlui/handle/123456789/13703Available in print form, East Africana Collection, Dr. Wilbert Chagula Library, Class mark (THS EAF TS191.T34M54)The research on quality of maintenance has been carried out for the purpose of investigation of factors influencing the quality of maintenance, which in turn affect the production output in terms of quality and capacity for Tanzania industries. There is limited literature that addresses the quality of maintenance. The approach used to attain the study objectives are synthesis of literature; statistical data analysis in identification of factors and finally formation of the model by use of multiple regression and statistical software SPSS version 15. The model is validated by using data collected from 21st Century Textile Ltd of Morogoro. Eventually, the stepwise regression was done by comparing the control and treatment data in order to test the reliability and validity of the model. By use of Durbin Wetson test, R2, and p- value test, the model were found to be valid, reliable and significance. The main result achieved was the developed quantitative model that integrates the refined factors. These factors are wages and salaries; experience of maintenance personnel; quality of spare parts; allocation of maintenance resources; correctness of maintenance action; duration for maintenance action; age of facilities and equipment; maintainability as well as reliability of services rendered. In summary, a regression equation model for predicting and explaining the quality of maintenance has been developed. The model main components are factors related to spare parts, human resources, maintenance strategies, facilities and equipment and functional quality.enIndustrial equipmentMaintenance and repairProduction managementQuality controlIndustryTanzaniaThesis
