Identification of Major Lean Production Waste in Automobile Industries using Weighted Average Method

Abstract

Industrial muda elimination is a major challenge that is faced by the experts in the day to day activities of production systems. Mostly there are seven types of industrial muda in lean systems such as Defects, Overproduction of things not demanded by actual customers, Inventories awaiting further processing or consumption, Unnecessary over-processing, Unnecessary motion of employees, Unnecessary transport and handling of goods, Waiting for an upstream process to deliver, or for a machine to finish processing, or for a supporting function to be completed. Every organization faces particular type of waste that occurs in day to day production activities. In order to find out the most influential lean waste based on the ranking, a survey has been conducted in 91 automobile industries based on the 5 point likerts scale to find the highly impacted lean muda. The survey results stating that 3 types of waste arising out of 7 waste which heavily affect the production system. Hence this work mainly deals with assessing the most deadly waste by ranking the major waste using the weighted average method in which each waste is assigned a weight. Based on the results, the major muda, which are identified that affects the production activities are discussed in detail and how this muda can be eliminated and incorporated with the production system are discussed

Identification of Major Lean Waste and Its Contributing Factors Using the Fuzzy Analytical Hierarchy Process

“…The introduction of lean tools and techniques is useful in transforming a company into a high performing lean enterprise. Arunagiri and Gnanavelbabu [17] dealt with the identification of major lean production waste in [18]. OPN leads to excessive work in process stocks [19].…”

Lean construction – LC bajo pensamiento Lean

“…Fuente. : Obtenido de: [20] La filosofía LEAN propone un modelo en el que después de la entrada hay un proceso de transporte y esperas antes de llegar a la transformación, luego inspecciones y, en muchas ocasiones, reparación de trabajos, para llegar al producto. Este modelo es llamado de transformación-flujo-valor -TFV (ver figura 2).…”

“…: Obtenido de [20] Un ejemplo del proceso de trasformación propuesto se muestra en la instalación de adoquín para la realización de una vía, donde se observan etapas que no estaban contempladas en el modelo inicial, pero que causan desperdicios (figura 3). Para determinar las actividades que generan pérdidas en la construcción, se hacen observaciones cortas de las actividades que realiza un trabajador en obra, y se categorizan en tres grupos de trabajo [16]:…”
