Lean Tools

In today's competitive environment, lean manufacturing becomes necessary across all industries. Lean production is a contemporary production technique of the new millennium. Lean manufacturing has varied synonyms just as lean management, lean production. It provides an extensive approach for decreasing the flow of non-value-added activities. Lean manufacturing is an excellent philosophy to minimize the period amongst client orders and supplies are ready for delivery through eradicating waste. Waste (Muda) is implicit like any process or activity that would not be adding value to the finished product or services. Waste is a severe problem emerging in the manufacturing industries; it causes non-value-added steps which do not expedite outstanding products and services. Waste is minimized with the aid of lean manufacturing. It is an integrated system that entails a minimal buffering cost for services offered and manufactured goods. The present research studies in the domain of Lean are examined to comprehend the execution level of several lean tools, benefits of implementation, and obstacles during the execution of Lean are also scrutinized in the reviewing. Several benefits and potential barriers that occur while implementing the lean culture in various organizations have been identified and listed in this paper.

Abstract The concept of Lean Manufacturing (or Lean Production) is widely present in the quality management systems of the best factories. Foundry plants in Poland have continuously been implementing modern management tools; however, the experiences of the authors show that the usage of lean tools is at a lower level in domestic foundries than in similar plants abroad. This was the reason why a survey was prepared and over 300 foundry plants were questioned regarding the application of Lean Manufacturing tools. The questions (20 in total) asked if and what tools are implemented in the plant and what benefits have been achieved, or why lean tools have not been implemented in a particular plant. The answers were thoroughly analysed and the results show that, among others, only 29% of all foundries use lean tools, and the main reason why most of them do not is that these tools are not understood well enough.

Shenzhen has been established as the technology and innovation center in China. The study reviews its economic development and environmental change over the past four decades. Specifically, it tests whether environmental Kuznets curve relationship between haze as a proxy indicator of environmental condition and gross domestic product (GDP) per capita holds in Shenzhen. The study also examines the contribution of Shenzhen’s secondary sector to its GDP and highlights some changes in the computer, communication and electronic product manufacturing industries over the years. We collected the official data from the Shenzhen Municipal Government. Economic, social and environmental changes in Shenzhen were identified using tables and stacked graphs. Environmental Kuznets curve revealed that the worst environmental condition appeared in Shenzhen during the period 2003–2004. Environmental analysis showed that Shenzhen’s computer, communication and electronic product manufacturing industries consumed 52,595 TJ of energy and produced 10.1 million tons CO2-eq in 2019. As gross output value of the industries was USD 336 billion in 2019, the industries had an energy efficiency of 156,716 MJ/million USD and an emission efficiency of 30.6 tons CO2-eq/million USD, improving by 74% and 65%, respectively, since 2008. Nevertheless, the industries should focus more on high value-added and low energy-intensive technologies and innovations. Additionally, the Shenzhen Government shall increase the use of clean energy sources such as nuclear, wind and solar power in order to sustain the continual improvement of energy and emission efficiencies for all industries.

Real World Situation

Lean manufacturing is a management philosophy derived from Toyota Production System (TPS) which aims to increase the overall values of the product or service provided to the customer through elimination of non-value added activities. In the era of globalisation, to remain competitive in the global market, many medium and small sized Indian industries adopt lean manufacturing. This paper focuses on implementation of lean manufacturing in Indian MSMEs. To examine the implementation, attributes which influence lean manufacturing are obtained and industries’ performances on these criteria are rated. In this paper, the methodology selected from many of the multi criteria models is the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). In the actual real world situation, because of the unreliable nature of the information gathered, the attributes are often not absolute and are imprecise. These data can be considered as fuzzy and the aim of this paper is to adopt TOPSIS decision making method to problems with fuzzy data. The rating and weights of each data are expressed as triangular fuzzy numbers. These attributes are then normalized and the TOPSIS methodology is carried out to determine the effect of implementing lean manufacturing technique in an industry. The best industry is identified by fuzzy TOPSIS on the basis of performance towards the considered attributes is consistent with results identified by TOPSIS.
