COMBINED APPLICATION PROPOSAL OF VALUE STREAM MAPPING (VSM) AND METHODS TIME MEASUREMENT UNIVERSAL ANALYSIS SYSTEM (MTM-UAS) METHODS IN TEXTILE INDUSTRY

Abstract

Due to high customer expectations in textile world, companies make great efforts in order to survive. Customers always expect best quality, best price and fastest service time. In this article, the method of VSM (Value Stream Mapping) was used together with MTM-UAS (Methods Time Measurement Universal Analysis System) in the production process of the textile industry. The lean manufacturing system, which is developed to provide optimal service to customers, aims both to eliminate wastes in the process and to reduce the time to minimum including time between delivering and the product design stage. Within the scope of this study, the duration of lead time is reduced by eliminating non value added activities in the flow of process with value stream mapping method which is one of the lean manufacturing tools. In order to accomplish requested sustainability of well-disposed standard procedures, it is preferred to use MTM-UAS methodology in this study. An optimal operational procedure is recreated with the aid of MTM-UAS to standardize human body movements. In consequence of the study, production lead time was reduced, recovery at duration of value-added activities were observed, actual body movements were standardized and unnecessary and extra movements were eliminated by using value stream mapping tool and MTM-UAS in textile industry. As a result, it is observed that production lead time was reduced at the rate of %60 and also, duration of non-value-added activities was improved at the rate of 60%.
