The principles of lean manufacturing that aid in the elimination of waste have helped the company meet ever increasing customer demands while preserving valuable resources for future generations. The implementation of lean and sustainable manufacturing was aided by the use of discrete event simulation and optimization to overcome deficits in lean’s traditional implementation strategies. Lean and green manufacturing can have a more significant, positive impact on multiple measures of operational performance when implemented concurrently rather than separately. These ideas are demonstrated by three applications. Keywords: lean manufacturing, green manufacturing, case-study, discrete event simulation, optimization 1 Introduction Manufacturers are under tremendous pressure to...

...LEAN MANUFACTURING Lean manufacturing is a management philosophy focusing on reduction of the seven wastes to improve overall customer value: • Over-production • Transportation • Inventory • Motion • Waiting time • Processing Itself • Defective Product (Scrap in manufactured products or any type of business.) By eliminating waste (muda), quality is improved, production time and costs are reduced. To solve the problem of waste, Lean Manufacturing has several "tools" at its disposal. These include constant process analysis (kaizen), "pull" production (by means of kanban) and mistake- proofing (poka-yoke). Key lean manufacturing principles include: • Pull processing: products are pulled from the consumer end (demand), not pushed from the production end (Supply) • Perfect first-time quality - quest for zero defects, revealing & solving problems at the source • Waste minimization – eliminating all activities that do not add value & safety nets, maximize use of scarce resources (capital, people and land) • Continuous improvement – reducing costs, improving quality, increasing productivity and information sharing • Flexibility – producing different mixes or greater diversity of products quickly, without sacrificing efficiency at lower volumes of production • Building and maintaining a long term relationship with suppliers through collaborative risk sharing, cost sharing and information sharing arrangements. Lean is...

In this paper we presented the main concepts, the application and adaptation way in different contexts, both in industry and in services. We showed a modern tendency which is taking shape more and more in the contemporary economic context, such as the integration of this concept with the Six Sigma concept, and thus we can talk about Lean Six Sigma, as an integrator method which guarantees high-class quality and lower costs.

...Action Plan – Implementing a Lean Transformation’ LEAN Final Project Alex Scholfield February 29, 2012 Summary Lean manufacturing can add significantly value to an organization by streamlining processes through the identification and elimination of muda or waste. Introduced by Toyota, Lean is more than just a tool, but a philosophy that needs to be adopted and incorporated into the culture of the organization. It is very important that the organization can see that leadership have bought in to the approach and are willing to support Lean. Numerous examples exist that demonstrate failed attempts at implementing Lean. It is important that organizations appreciate that they cannot simply wake up one day and choose to introduce Lean. It took Toyota many years to develop their culture into one of continuous improvement. For organizations that are new to Lean, the effort required will be significant in order to realize the true value associated with Lean principles. Poor planning will almost certainly result in disappointment and leave a strong negative association with any future Lean attempts along with a big investment with little to no return. With a focus on continuous improvement and continuous flow, manufacturing based on pull rather than push demand will assist organizations in becoming Lean. While Lean is a long journey, it can be one that returns significant value to an organization. What follows is a view of the history of Lean, some of the tools such as...

...Lean Management In Automobile Industry Lean Management In Automobile Industry Arvinder Singh, Bargavi Poloju, Inderpreet Kaur, Inderjeet Kaur, Jaskaran Singh Gill Eastern Institute of Technology September 10, 2015 Abstract Lean and six sigma are widely known business improvement processes for industries /organisations these days for achieving drastic results, which are majorly cost cutting, quality maintenance and time management by specializing in processes to boost performance. Nowadays, There are some industries that are even integrating lean and six sigma into a more cohesive strategy i.e., lean sigma in order to establish even more powerful and effective process which focuses at eliminating wasteful activities and retaining most of the strengths of each activity. Lean Sigma aims to combine waste eliminating strategies of Lean Thinking with variability reducing techniques of six sigma to promote growth and increase revenue from the bottom line of organisations(M. Kumara). Lean management is outlined as a consistent and a methodical approach to determining and eliminating waste through continuous improvement, flowing the merchandise at the pull of the client in pursuit of perfection. The idea of lean management was developed for maximizing the resource utilization through reduction of waste, and eventually lean was developed in response to the unsteady and ever-competitive business organisations. For organisations to face major challenges and competition can be...

...The Principles, Benefits and Compliance of Lean Accounting As a way to reduce costs, manufacturing businesses today are looking for a leaner approach to production and are focusing on the overall process of producing an item to eventually sell to a consumer. This process is called the value stream, which is defined in Cost Accounting: A Managerial Emphasis as “the value-added activities needed to design, manufacture, and deliver a given product or product line to customers” (Horngren, Datar, & Rajan, 2014, p. 635). With the assistance of technology advancements to support with the communication of the different components of the value stream, processes have been developed, like Just in Time (JIT) production, that allow for the lean production of merchandise. Dan Woods describes this lean production process, in an article published in Forbes: “In a lean process, the demand signals pull the materials through the flow processes and the right number of products is created with as little waste as possible. When all the suppliers of materials are also making their processes lean, the result is that the entire supply chain is extremely responsive and efficient. “ (Wood, 2009) To go along with this lean production system, lean accounting was developed as “a costing method that focuses on value streams, as distinguished from individual products or departments, thereby eliminating waste in the accounting process” (Horngren, Datar, & Rajan, 2014, p. 635). This paper will summarize...

...selected techniques. Lean Production A business’s operation is only as fast as its slowest process. In order for Riordan Manufacturing to be successful, it needs to seek out and remove bottlenecks. By Riordan identifying these bottlenecks in the operation, they can improve the output of the entire process, which would make it definitely worth the effort. Lean production aims to combine the flexibility and quality of craftsmanship with the low costs of mass production (Economist, 2009). In a lean production setting Riordan will organize its workers into cross functional teams that are expected o accomplish a variety of tasks. This differs from mass-production assembly lines where worker repeat monotonous tasks. Product components are delivered to the various teams just-in-time, and each worker is expected to stop production if an error is discovered. Mass production lines rarely shut down to correct errors. It is expected that an established lean-production line is more efficient than a conventional mass-production assembly line because problems are confronted and solutions are implemented in order to avoid repeating mistakes. Communication is open and transparent in a lean production environment. It is common for production, design, and supply to have constant contact with one another in order to improve and overcome challenges. As a result problems can be dealt with immediately and quality and efficiency increases. The establishment of a lean production system will...
