Abstract

Purpose

The purpose of this paper is to uncover the significance of SMED in manufacturing environments.

Design/methodology/approach

The paper gives setup instructions and guidelines to prepare the standardized setup procedure without ignoring actual constraints in production environment. It uses a case study in a small-scale manufacturing unit of northern India to generate an integrated setup reduction approach, utilizing Single Minute Exchange of Die (SMED)-based industrial engineering tools to achieve faster setups. It describes the feasibility of quick changeovers in small enterprises based on an “SMED” approach. Finally, the paper carries out empirical analysis of the financial/non-financial benefits incurred from setup reductions.

Findings

Setup activities are a vital part of the production lead time of any product and so affect overall product cost. Industrial engineering techniques have been used to analyze the existing procedure of setups. A SMED approach can help eliminate unwanted activities, externalize the internal activities, if possible, and reduce them by simplification or standardization.

Originality/value

The paper demonstrates the practical application of SMED showing how it can bring real breakthroughs in reducing setup time in small-scale manufacturing.

Abstract

Purpose

This paper recommends a method entitled “SMED 4.0” as a development of conventional single minute exchange of die (SMED) to avoid defect occurrence during production and improve sustainability, besides reducing setup time.

Design/methodology/approach

The method builds upon an extensive literature review and in-depth explorative research in SMED and zero defect manufacturing (ZDM). SMED 4.0 incorporates an evolutionary stage that employs predict-prevent strategies using Industry 4.0 technologies including the Internet of Things (IoT) and machine learning (ML) algorithms.

Findings

It presents the applicability of the proposed approach in (1) identifying the triple bottom line (TBL) criteria, which are affected by defects; (2) predicting the time of defect occurrence if any; (3) preventing defective products by performing online setting on machines during production as needed; (4) maintaining the desired quality of the product during the production and (5) improving TBL sustainability in manufacturing processes.

Originality/value

The extended view of SMED 4.0 in this research, as well as its analytical approach, helps practitioners develop their SMED approaches in a more holistic way. The practical application of SMED 4.0 is illustrated by implementing it in a real-life manufacturing case.

Abstract

Purpose

The paper seeks to reduce or eliminate the small stop time loss using SMED in a lean manufacturing environment.

Design/methodology/approach

The study uses the lean manufacturing single minute exchange of dies (SMED) technique to reduce or eliminate the small stop time loss. The overall equipment effectiveness (OEE) is measured before and after the improvements are implemented.

Findings

The application of the single minute exchange of dies (SMED) technique in a manufacturing industry (XYZ Corporation) completely eliminated the small stop time loss. The SMED technique which has been only widely used to improve the changeover loss has been proven to be an effective approach to also tackle the small stop, a loss which has been regarded as one of the most difficult losses to be reduced among all the six big OEE losses. The elimination of the small stop has resulted in a valuable 2.08 percent improvement of XYZ's OEE.

Practical implications

The finding from this study is expected to benefit lean organizations in pursuit of tackling their small stops losses.

Originality/value

Although the SMED technique's impact and contribution to reduce or eliminate setup and changeover time loss is undeniable, the authors have extended the successful application of this technique to another key area of OEE's big loss, i.e. small stop.

Abstract

Discusses the practical application of the single minute exchange of die (SMED) within a textile processing operation. First, the operational environment is presented, and the SMED application is considered against a changing business requirement. The current approaches to SMED are then discussed within the context of traditional textile manufacture. The prerequisite requirements for successful SMED application, defined in this paper as SMED‐ZERO, are then presented and discussed. Concludes by suggesting that all of the SMED‐ZERO attributes must be in place before the traditional SMED techniques can be applied successfully.

Abstract

Purpose

There can be activities that cannot reduce times by conventional single minute exchange of die (SMED) tools. In this case more advanced tools are needed. The purpose of this paper is to integrate the fuzzy Taguchi method into the SMED method in order to improve the setup time. The reason for using fuzzy logic is the subjective evaluation of factor’s levels assessment by experts. Subjective assessment contains a certain degree of uncertainty and is vagueness. The fuzzy Taguchi method provides to determining optimal setup time parameters in an activity of SMED. So it is possible to reduce time more than the conventional SMED method.

Design/methodology/approach

In this study, the SMED method and the fuzzy Taguchi method are used.

Findings

In this study, it has been shown that the setup time is reduced (from 196 to 75 min) and the optimum value can be given at the intermediate value by the fuzzy Taguchi method.

Originality/value

In this limited literature research, the authors have not found a study using the fuzzy Taguchi method in the SMED method.

Abstract

Purpose

Shorter lead time with low price and quality product demand is pivotal in the garment industry. Pressure on production lead time stresses the importance of reducing style changeover time in manufacturing factories, and this paper aims to contribute to solving the challenge by showing how the single minute exchange of die (SMED) methodology in practice can be adapted to garment factories in developing countries.

Design/methodology/approach

The paper investigates three cases of SMED implementation integrated with responsible, accountable, consulted, informed (RACI) matrices in garment factories in an action research approach. Both quantitative and qualitative methods are applied.

Findings

The study shows a reduction of 50% to 64% of changeover time with SMED implementation measured with two key indicators – throughout time and time to reach peak production. Moreover, the implementation depends on the application of the RACI matrix for the distribution of responsibility as well as integration with the basic production flow before and after the application of SMED.

Practical implications

The study can guide better SMED implementation in garment factories with limited investment by stressing the need to adapt to the specifics of the garment industry, secure the division of responsibility and integrate SMED in the production flow before and after the changeover.

Originality/value

Limited research on the application of SMED in the garment industry. This paper contributes to understanding the specific conditions for successful implementation in the garment industry in developing countries and addresses additional activities that help secure a sustainable implementation process.

Abstract

Purpose

The purpose of this paper is to uncover the significance of quick changeovers in die‐casting foundry environments.

Design/methodology/approach

The paper gives set‐up instructions and guidelines to prepare the standardized set‐up procedure without ignoring actual constraints in foundries. It uses a case study in a medium scale piston foundry to generate an integrated set‐up reduction approach, utilizing single minute exchange of die (SMED)‐based industrial engineering tools to achieve faster set‐ups. It describes the feasibility of quick changeovers in foundry small and medium enterprises based on a “SMED” approach. Finally, the paper carries out empirical analysis of the financial/non‐financial benefits incurred from set‐up reductions.

Findings

Set‐up activities are a vital part of the production lead‐time of any product and so affect overall product cost. Tools like Pareto analysis, root‐cause analysis and method study have been used to analyze the existing procedure of set‐ups. A SMED approach can help eliminate unwanted activities, externalize the internal activities, if possible and reduce them by simplification or standardization. The application of other tools such as 5S, Poke‐Yoke and specific tool‐kits are suggested to further reduce set‐up times.

Originality/value

The paper demonstrates the practical application of SMED showing how it can bring real breakthroughs in productivity to small and medium scale foundries.

Abstract

Discusses the derivation of current changeover improvement methodologies from the work of the Japanese engineer/consultant Shigeo Shingo. Argues that under the interpretation and widespread adoption of the single minute exchange of dies (SMED) philosophy, substantive design‐based solutions are being overlooked in favour of incremental, low cost, team‐based approaches which emphasize organizational changes to the changeover. Identifies difficulties which can arise with existing approaches to changeover improvement and the relative merits of emphasis on design or organization are discussed. Pays particular attention to the problems which have been observed in sustaining levels of improvement.

Abstract

Purpose

This paper presents Quick Changeover Design (QCD), which is a structured methodological approach for Original Equipment Manufacturers to drive and support the design of machines in terms of rapid changeover capability.

Design/methodology/approach

To improve the performance in terms of set up time, QCD addresses machine design from a single-minute digit exchange of die (SMED). Although conceived to aid the design of completely new machines, QCD can be adapted to support for simple design upgrades on pre-existing machines. The QCD is structured in three consecutive steps, each supported by specific tools and analysis forms to facilitate and better structure the designers' activities.

Findings

QCD helps equipment manufacturers to understand the current and future needs of the manufacturers' customers to: (1) anticipate the requirements for new and different set-up process; (2) prioritize the possible technical solutions; (3) build machines and equipment that are easy and fast to set-up under variable contexts. When applied to a production system consisting of machines subject to frequent or time-consuming set-up processes, QCD enhances both responsiveness to external market demands and internal control of factory operations.

Originality/value

The QCD approach is a support system for the development of completely new machines and is also particularly effective in upgrading existing ones. QCD's practical application is demonstrated using a case study concerning a vertical spindle machine.

Abstract

The paper reports a study into set‐up time reduction and mistake proofing methods in a small company involved in the machining of precision components in small batches with high variety for the aerospace industry. The company has made some set‐up reductions mainly using work study related methods and in one manufacturing cell by the use of the Single Minute Exchange of Die (SMED) methodology. Mistake proofing devices in the form of fouling pins and offset holes have been developed for the family of components manufactured in this cell. Until recently the set‐up times were not measured and worse still were considered as productive hours. As a consequence, there was a lack of awareness and motivation amongst operational personnel to reduce set‐up times and knowledge of SMED was limited to a small group of individuals. This, along with the lack of investment in mechanisms to aid set‐up time reductions and prevent errors, has restricted the use of this type of methods and technology. However, there is evidence that the demands made by the company’s major customer will lead to increased efforts to put into place these types of changes.
