Abstract
Abstract The lean index is the sum of weighted scores of performance variables that describe the lean manufacturing characteristics of a system. Various quantitative lean index models have been advanced for assessing lean manufacturing performance. These models are represented by deterministic variables and do not consider variation in manufacturing systems. In this article variation is modeled in a quantitative fuzzy logic based lean index and compared with traditional deterministic modeling. By simulating the lean index model for a manufacturing case it is found that the latter tend to under or overestimate performance and the former provides a more robust lean assessment.

Abstract Multiple lean metrics representing performance for various aspects of lean can be consolidated into one holistic measure for lean, called the lean index, of which there are two types. In this article it was established that the qualitative based lean index are subjective while the quantitative types lack scope. Subsequently, an appraisal is done on techniques for quantifying qualitative lean metrics so that the lean index is a hybrid of both, increasing the confidence in the information...

Lean principles have long been recognised as a competitive advantage. Although there are several measures for various aspects of lean production in the literature, there is no comprehensive measure for overall lean implementation in business firms. An appropriate measurement tool is needed to assess the effectiveness and efficiency of the lean implementation throughout the entire organisation. Based on lean research, a comprehensive tool called the leanness assessment tool (LAT) is developed, us...

Aperformance metric and goal-setting procedure is defined for an order fulfillment operation. In this operation, order requests arrive continuously, and filled orders are shipped at a specific time each day. The metric links the continuous operation of order fulfillment to the scheduled shipment times. To prescribe goals against the metric, a performance model is developed that incorporates the motivational effect of a goal. Goal-Setting Theory is used to establish the performance goal and to sh...

In this paper, we consider unpaced synchronous transfer lines producing a single product. The transfer line stations are arranged in a series configuration, have no buffers, and are subject to operation-dependent failures. Throughput is an important performance measure for transfer lines, and we have adopted that measure. Analytical methods for determining capacity of such transfer lines are available only for the simplest systems, but we show Monte Carlo simulation to be a fast, flexible, easy, ...

Agility is the performance measure of agile manufacturing (AM) practices and with the increasing adoption of AM systems its assessment has gained in importance. This study has been undertaken to fill the observed research gap that no research has been attempted to validate an agility assessment result using an alternative effective method. The agility assessment of an Indian electric automotive car manufacturing organisation has been done using a scoring approach and validated using an effective...

This article focuses on the overall equipment effectiveness (OEE), a key performance indicator typically adopted to support Lean Manufacturing and Total Productive Maintenance. Unfortunately, being a deterministic metric, the OEE only provides a static representation of a process, but fails to capture the real variability of manufacturing performances. To take into account the stochastic nature of the OEE, an approximated procedure based on the application of the Central Limit Theorem is present...

Manufacturing organisations have been witnessing a transition from mass manufacturing to lean manufacturing. Lean manufacturing is focused on the elimination of obvious wastes occurring in the manufacturing process, thereby enabling cost reduction. The quantification of leanness is one of the contemporary research agendas of lean manufacturing. This paper reports a study which is carried out to assess the leanness level of a manufacturing organisation. During this research study, a leanness meas...

Lean manufacturing has become an important avenue for both academics and practitioners in recent times. Many organizations around the world have attempted to implement it but the lack of a clear understanding of lean performance and its measurement will contribute to the failure of lean practices. There are many papers, articles, and reports that address lean techniques and tools, but few studies are found to focus systematically on lean performance evaluation. In order to fill the current gap, ...

Purpose – The extant literature fails to provide an efficient method to measure leanness of any manufacturing firm. The purpose of this paper is to discuss the concept of leanness and to provide an efficient measurement method for measuring leanness.Design/methodology/approach – Measurement method is based on the judgment and evaluation given by leanness measurement team (LMT) on various leanness parameters such as supplier's issues, investment priorities, Lean practices, and various waste addre...

In this article, two alternative approaches to include variability analysis in value stream mapping (VSM) are presented. Notoriously, VSM is one of the best tools to map a process and to identify its main criticalities in order to enhance lean manufacturing. Unfortunately, in the standard approach, data are recorded on the map as deterministic, disregarding the real variability of the process. This is a strong limit because, especially within manufacturing processes, variability has a significan...

Purpose Lean implementation is a strategic decision. The capacity of organisation to be “Lean” can be identified before lean implementation by assessing leanness of an organisation. This study aims to attempt developing a holistic leanness assessment tool for assessing organisational leanness. Design/methodology/approach A neuro-fuzzy leanness assessment model for assessing the leanness of a manufacturing system is presented. The model is validated academically and industrially by conducting a c...

The constant business pressure to increase operational efficiency promotes Lean. However, studies indicate that Lean has under delivered as a sustainable practice, with few companies developing a “culture of Lean”. This is essentially because practitioners perceive Lean as a set of tools and techniques, instead of adopting a systems approach to addressing issues. Existing approaches to Lean teaching also contribute to the problem; they are not geared towards creating a critical problem-solving m...

The paper reveals how lean instruments and metrics applied in transportation translates the importance of logistic visibility and shared information between shippers, brokers, carriers and customers along the supply chain management. Recreating a new transportation network emphasizes the idea of discovering practical strategies and actions of reducing muda in terms of efficiency and costs. Transportation cost has to be focused on frequency of trips, shipping size, distance travelled, guide route...

Abstract Nowadays, the manufacturing industry is increasingly globalized and competitive, where the quality, cost, variety and fulfillment of delivery deadlines are fundamental factors for the customer. Therefore, to better meet these demands companies need to find strategies to make their processes more flexible and efficient. In the modern industrial environments the elimination of waste in order to concentrate as much as possible on value-added activities often leads to a reduction in the dow...

This research was conducted on the company engaged in the production of Fast Moving Consumer Goods (FMCG). The production process in the company are still exists several activities that cause waste. Non value added activity (NVA) in the implementation is still widely found, so the cycle time generated to make the product will be longer. A form of improvement on the production line is by applying lean manufacturing method to identify waste along the value stream to find non value added activities...

Lean is an effective and tested method of reducing operating costs and removing waste from manufacturing operations. Lean principles are defined for the growth and survival of the industries related into production and also to the service sector. As needs are increasing, expectation of quality work is also increasing. Using lean production principles, employing Kaizen events and reducing unnecessary activities and variations via continuous policy updating keeps business competitive. To produce q...
