Quantitative Analysis of The Factors Influencing Effective Maintenance At A Selected Textile Factory In Tanzania

Abstract

The study on quantitative analysis of the factors influencing maintenance effectiveness has been carried out for the purpose of investigation of factors, which in turn affect the production output in terms of quality and capacity for Tanzanian industries. The approach used to attain the study objectives is the Multiple Regressions Model. Eventually, a case study industry was selected. 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 Watson test, R², and P-value test, the models were found to be valid, reliable and significant. The main result achieved was the quantified factors influencing the maintenance effectiveness. These are the factors related to spare parts, human resources, maintenance strategies, facilities and equipment as well as functional quality. Through a developed model, the identified critical factors were mentioned and strategies were proposed to be adopted for improving maintenance effectiveness for the case study industry. The recommended strategies were as follows: wages that can meet the basic living standard requirements, in-house and outside work training, reputable supplies of genuine spare parts to be selected among the main suppliers, use of set standard specifications for repetitive works, phase-out uneconomical old technology and emphasis on interactive quality so as to be able to offer consistent and reliable maintenance services.
