The Ratio-Delay Method of the Manufacturing System Analysis

Abstract

This paper describes the application of a ratio-delay to a study of operations of mechanical Job-Shop production in Samara factory. To analyze the operations efficiency it may be necessary to obtain organizational and technical data in each job stages. In fact, ratio-delay is an effective tool to determine direct labor productivity for shop floor activities. In the context of manufacturing operations, ratio-delay can determine productivity levels as a baseline that provides focus for new “industrial engineered” improvement measures of complex re-engineering project or lean management.
