Abstract

Lean has established itself as the primordial approach to obtain operational excellence. Its simple and intuitive techniques focus on reducing lead time through continuous improvement, involving all levels of employees in the organization. However, the rate of successful implementations has remained low. This paper contributes to the understanding of continuous improvement in a Lean context, by analyzing a database of almost 10.000 improvement actions, from 85 companies, covering the time frame 2010–2018. It discusses categories of actions, their impact and cost, as well as key characteristics of the companies. It proposes an objective criterion to identify “success” and “failure” in Lean implementation and tries to link these to operational results. It is probably the first time an analysis of this magnitude on the subject has been performed.

Abstract

This study is aimed at investigating the functionality of Visual Performance Management (VPM), along with determining the necessary features such a method should demonstrate to be an effective and meaningful tool for the development of Lean Management in an organisation. Based on the analysis of a case study in a large manufacturing organisation, a crosscutting assessment of such a system was made, a literature review proves the lack of such a comprehensive study. Six critical features of VPM were identified, they are very practical and giving many interesting insights into studied Lean method. The view emerged from empirical investigated shows VPM as of the wider functionality then only visual information exchange methodology. The VPM serves as cascade information exchange system and has substantial potential to support employee’s participation.

Abstract

The article presents the possibility of increasing the production efficiency in an enterprise dealing in the production of lounge furniture. The literature review shows that Poland is the sixth country in the world in the amount of furniture production. It is also one of the leading exporters of upholstered furniture in Europe. Each year, the value of furniture sales production increases by a few percentage points. Due to the constantly growing customer orders, many companies in this industry are struggling with delays in delivering products to customers. This problem also occurs in the analyzed company. While analyzing the production process, the occurrence of a large number of non-conformities was also noticed. An analysis was carried out to indicate the number of non-conformities and the place of their occurrence. The FMEA analysis was used, which indicated which non-conformities are the most important, and the 5Why method, which allowed to indicate the cause of their occurrence. The analysis of production processes showed which activities do not bring added value and how they can be eliminated at no cost. All these measures contributed to increasing the efficiency of the production of lounge furniture.

Abstract

The paper presents the technology and organization of the artistic cast production. On the basis of the actual cast production system, the

manufacturing process was shown, in particular sand–piece moulding, which is a very important process and a time-consuming part of the

entire manufacture of the casts. The current state of the production process as well as the organization of the work and production

technology were analysed with the use of methods and techniques of production improvement, the Lean Manufacturing concept and

computer systems. The results of the analysis and studies were shown with use of schemes and graphs of the layout of the production

resources, a flow chart of the production process, value stream mapping, and a costs table for the production and modernization of the

moulding stage. The work has shown that there are possibilities to improve the artistic cast production system. This improvement leads to

increased productivity, lower production costs of artistic casts and increased competitiveness of the foundry.

Abstract

Studies linking the use of lean practices to company performance have been increasing as

markets are becoming more competitive and companies are eager for reducing waste and

therefore implementing the Lean Management (LM) philosophy to improve performance.

However, results from these studies have found various and different impacts and some light

is needed. Extant literature was reviewed and, to achieve the research objective, a metaanalysis

of correlations was carried out. The obtained results suggest a positive relationship

between some lean practices and performance measures. Furthermore, the presence of moderators

influencing the relationship between lean practices and performance outcomes is

highlighted in our results. To our best knowledge, this is the first research that proposes

a comparison of results from primary studies on Lean implementation, by analysing the

linear relationship between lean practices and enterprise performance. It fills this gap and

therefore represents an important contribution.

Abstract

One of the key factors of a competitive economy is creating a strong, internationally competitive SME sector. This essay is based on the fact that management tools used in the SME sector are insufficient. With the development of these tools, the competitiveness of companies could improve. According to the literature, using lean thinking has a positive influence on the company’s effectiveness, and also proved that lean approach can be successfully extended out of the car industry, into the limitedly resourced SME sector, too. Even though the topic of lean manufacturing is analysed by many studies, there is a lack of papers dealing with its usage in the SME sector. The originality of this paper lies in analysing the current status of using lean manufacturing practices among the Hungarian SMEs operating in the manufacturing industry. The paper includes an examination about how deeply the elements of lean thinking are present in the Hungarian SME sector, how large the development reserves are, and whether there is a difference between the usage of lean practices. A structured questionnaire was used for data collection. SMEs’ representatives, mostly CEOs and managers from the Hungarian manufacturing industry participated in the survey. The sample contained 128 observations. The study has two control variables, which are the size of the company and the relation to the lean management. The survey brought the following results. First of all, it shows that the level of using lean is low among the Hungarian SMEs. Furthermore, customer orientation is a key factor in the sector, however, there are considerable possibilities for progress by the inner processes and the handling and involvement of the suppliers. Firstly, a good basis to increase the effectiveness could be the creation of thinking in processes influencing the supply chain. Secondly, the development of the leadership and the involvement of the employees at some level are also significant. Key findings is that without state incitement and the involvement of outside experts, progress cannot be expected to spread on a broad scope. The background of the research method was created to fit the available literature and to capable to be used in other countries, too. Moreover, this way the available information can be expanded with a regional dimension, in case further studies are going to be made.

Abstract

The purpose of this research is to develop a Lean-RFID based waste identification system (LRWIS) for small-medium manufacturing companies. The specific objective of this research is to develop and implement the LRWIS from integrating the appropriate lean tools and advanced technologies for wastes reduction and inventory management. Subsequently, the framework was converted into a system for a small-medium sized wood processing manufacturer in Malaysia and integrated into a computerized program. The LRWIS can monitor real-time inventory and production status so the manufacturer can optimise the quantity of the primary products and deliver them on time as per the RFID information of each container. The manufacturer can also make decision instantly for controlling and changing different products in the production progress. The system provides simple constructed framework under a low cost infrastructure, yet it is of practical value in reducing the wastes and also optimising the production process.

Abstract

A robust manufacturing sector is imperative for achieving sustainable and inclusive development.

Also, in the Indian context, Micro, Small and Medium Enterprises (MSMEs) are

of vital importance due to their contribution to GDP, exports and employment. Indian

Government has launched many schemes to vitalize and improve the competitiveness of

Manufacturing MSMEs. ‘Lean Manufacturing Competiveness Scheme’ (LMCS) is a huge

step aimed to act as a catalyst for lean adoption by Indian MSMEs. This paper uses SAP

LAP framework to address critical questions regarding lean adoption by Indian manufacturing

MSMEs in the context of the government scheme ‘LMCS’. The study adds to the

existing body of knowledge on lean manufacturing that emphasizes on the importance of

soft issues while implementing lean. It also benefits the stakeholders by suggesting suitable

actions that can be taken to further improve the competitive priorities of MSMEs.

Abstract

Currently, we live in a culture of being overly busy, but this does not translate into efficiency, speed of implementation of the actions taken. Enterprises are constantly looking for methods and tools to make them more efficient. The most popular method of production management is Lean Manufacturing, less known is Theory of Constraints. This work is a continuation of the research on the comparison of these methods with apply a computer simulation, which the analyzed production process in the selected enterprise, after 24 hours and week. An attempt was made to simplify the comparison of the methods based on the obtained simulation in terms of costs. In analyzed case, more advantageous solution is to use the DBR method. To produce various orders that do not require 100% production on the bottleneck position, the use of Kanban is a frequent practice as it provides greater flexibility in order execution.

Abstract

Value stream mapping (VSM) is a well-known lean analytical tool in identifying wastes, value, value stream, and flow of materials and information. However, process variability is a waste that traditional VSM cannot define or measure since it is considered as a static tool. For that, a new model named Variable Value Stream Mapping (V-VSM) was developed in this study to integrate VSM with risk management (RM) using Monte Carlo simulation. This model is capable of generating performance statistics to define, analyze, and show the impact of variability within VSM. The platform of this integration is under Deming’s Plan-Do-Check-Act (PDCA) cycle to systematically implement and conduct V-VSM model. The model has been developed and designed through literature investigation and reports that lead in defining the main four concepts named as; Continuous Improvement, Data Variability, Decision-Making, and Data Estimation. These concepts can be considered as connecting points between VSM, RM and PDCA.

Abstract

The paper discusses possible applications of wireless technologies in support of lean manufacturing tools. The typology of lean tools is provided. It distinguishes three main categories, which are identification and analysis of waste, improvement implementation, and process monitoring. The set of lean tools was analyzed in terms of information requirements. On the other hand, the typology of wireless technologies was discussed including RFID and Wi-Fi. The literature review of wireless technology applications for support of lean tools was conducted. The literature was systematically reviewed from the point of view of specific technologies and specific tools which were the subjects of the analyzed publications. Both typologies were synthesized to establish a framework for wireless technologies applications in the context of lean manufacturing implementation. It also could serve as a guideline for lean practitioners and implies future research directions. This paper is an extended version of paper published by [1].

Abstract

Lean manufacturing [LM], quality management system and environmental management system are clear initiatives with a goal of improving effectiveness and efficiencies of organizations. Many organisations tackle lean philosophy, ISO standards individually but this kind of attempt do not focus on the synergy and the advantage from the potential collaboration. This paper aims to present the possibility of integration Lean Management concept with ISO management systems – Quality Management System [QMS] ISO 9001and Environmental Management System [EMS] ISO 14001 already implemented in the enterprises. The integration of these three concepts can be obtain due to improvement of main KPI’s defined in the organization. Based on critical research literature and participant observation presented as a case study (one of the author of the paper works as a consultant and is being implemented Lean Manufacturing concept in different organization since ten years) authors defined concept of integration of EMS and QMS (already implemented in the organization) with chosen Lean Management tools. Concept has been developed based on literature analysis and experience of the authors. Results and summary from concept implementation has been described in last chapter of the paper.

Abstract

The main purpose of this article is to present an author’s methodology of production levelling

and to show the impact of levelling on the time during which the product passes

through the process and on staff performance. The article presents the analysis of literature

concerning the method of improving the production process, especially taking production

levelling into consideration. The authors focussed on the definition and methodologies of

production levelling. A diagram of interrelations showing determinants and efficiency measures

of production levelling as well as an author’s production levelling methodology have

been presented. An example of the implementation of production levelling in one of the departments

of a company manufacturing surgical instruments has also been shown. Analysis

of the current state, stages of implementation and end effects have been presented. Attention

was focussed on the time during which the product passes through the process and on staff

performance.
