“…By implementing SMED, there is a significant reduction of cast on strap setup time and heat seal setup time, i.e., by 54 and 47 percent, respectively. Desai and Warkhedkar (2011) analyzed the setup time of a small factory which manufactured a large variety of precision components in small batches. SMED technique was applied on machine BA4156 used for the production of Lorenz gear.…”

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.

“…Single Minutes of Exchange Die (SMED), initiated in the early 1950s by Shigeo Shingo is the most popular approach to reduce setup time and provide quick equipment changeover and rapid die exchange (Desai & Warkhedkar, 2011). The objective of SMED can be achieved by reducing the setup time, that is, the time elapsed between producing the last good product of the first lot and the time of producing the first good product of the next lot (Almomani et al, 2013).…”

Single Minutes of Exchange Die (SMED) is a widely applied approach in reducing the changeover time of the machines. The time reduction can be made by converting the activities that need to be executed while the machine is stopped to the activities that can be executed while the machine is running. The former is called an internal setup activity while the latter is called an external setup activity. The objective of this paper is to evaluate this converting process dynamically. Since the company tried to improve the changeover year by year, the result in the previous year will give the certain effect to the activities in the following year. Therefore, it is necessary to observe the performance 's trend of the changeover's activities. In this paper, both internal and external setup time of a metal stamping company was collected from 2011 to 2014. The Network Data Envelopment Analysis (DEA) has been used to evaluate the performance of the SMED activities in the company by considering all the relationship between the activities in every year. As a result, we can determine the performance of an activity where the result can be used as a guideline for further improvement in the company.

“…The bottlenecks were identified as the hot forging, cold forging and machining departments. The changeover time was reduced from 45 min to 8.14 min [27]. Joshi and Naik [28] collected data from small-scale industries that had implemented SMED in India.…”

Optimising Changeover through Lean-Manufacturing Principles: A Case Study in a Food Factory

2022

Operations management is a key aspect in any manufacturing business. Optimising the management of manufacturing operations allows improvement of the productivity and efficiency of industrial activities. To achieve this, reducing waste from manufacturing processes and, therefore, implementing lean-manufacturing principles, is key. This article presents a case study to reduce waste in changeover processes at a ready-meal manufacturer based in South Yorkshire, UK. We identified a large number of activities as part of the changeover process. We applied the Single Minute Exchange of Dies (SMED) methodology to reduce and, whenever possible, eliminate changeover, and line hopping to further optimise changeover. After implementing improvement measures, changeover time was reduced by nearly 30%, OEE was increased to over 70%, and labour costs were reduced by 10%. This shows how lean principles can aid in implementing more effective and economically sustainable manufacturing operations.
