Lean Manufacturing

Lean manufacturing is the production of goods using less of everything than in mass production: less human effort, less manufacturing space, less investment tools and less engineering time to develop a new product. A company becomes lean by continuously increasing its capacity to produce high-quality goods while simultaneously decreasing

In accomplishing this, the JIT lean production process will minimize use of facility space, materials and supplies, stocks, labor, capital and time. This, in turn, will reduce costs by increasing production efficiency and overall output.

Lean Manufacturing system pursues optimum streamlining throughout the entire system by the elimination of waste (non-value added/ waste) and aims to build quality into the process while recognizing the importance of cost reduction.

Lean is defines the manufacturing philosophy that reduces the time between the shipping and customer demand, which based on the systematic method by eliminating waste, that means giving the customer what they want when they want it, and don 't waste whatever. Rahmana, Sharif and Esa (2013) suggested lean production is mentioned to improve the company 's performance from the philosophy in reducing waste in order. That means, lean system destination is the decrease cost by removing the non-value activities, which they are applying a category of tools and techniques for checking and eliminating defective in the production process. In the Evenort Company should emulate the five overriding principles of lean thinking in terms of implementing lean that there is guarantee the company has been driving correctly in the lean manufacturing (Cardiff 2015) as can show in table 1.

So the elimination of waste is the basic principle of lean manufacturing. Waste sources are all related to each other and getting rid of one source of waste can lead to either elimination of, or reduction in others. The most important source of waste is inventory. Work in process and finished parts inventory do not add value to a product and they should be eliminated or reduced. When inventory is reduced, hidden problems can appear and action can be taken immediately. There are many ways to reduce the amount of inventory, one of which is reducing lot sizes. Reducing lot sizes however, should follow by a setup time reduction so as to make the cost per unit constant as economic order quantity states.

The purpose of this literary review is to achieve insight into lean manufacture and how it can be applied within a manufacturing environment. With global contention, it is important for maker to remain competitive in their respective marketplace and to understand the principles of lean manufacturing and the step to implement them to ensure that they are on the leading edge of manufacturing. This literary review describes the below mention principles.

As is obvious by now, there are clear differences between typical production process and the lean production model. Suited for the mass production strategy of the last century, the manufacturing cycle of the typical production process primarily engages in cost accounting whether periodic or

The "Lean Manufacturing" (Womack, Jones & Roos, 1990) term is a managerial philosophy which tries to eliminate waste as much as possible during the manufacturing process. For example maximize use and reuse of raw materials, decrease the amount of excess supply and defective products, effective shipping & handling and consecutive manufacturing process. The second factor managers must relate to is reduction in the amount of waste in the organization's building itself. For instance total consumption of water and energy should be minimized as well. Then, the organization's board has to structure its vision, and set specific goals relating to environment issues, for the upcoming years.

Abstract The ‘‘lean’’ approach has been applied more frequently in discrete manufacturing than in the continuous/process sector, mainly because of several perceived barriers in the latter environment that have caused

The primary objective of lean is to produce more value for customers with fewer resources. The advantage of lean production is it helps in reducing the cost of production by eliminating unnecessary materials used in production. Disadvantages of lean production are that it depends on the inventory the supplier keeps in his hand of which the suppliers often prefer in keeping a small amount of stock which is not acceptable in a lean production system. The material supply can delay being delivered to the production house due to unavoidable circumstances that may include transportation breakdown, suppliers strike or specific product not available (Theory of Constraints

This will in turn help the company honor its promises to customers which will create customer goodwill. Again a lean production ensures the company reduces wastage to the bare minimum. (Wolfe, 2011) This is very helpful in pursuing lower costs. Key areas addressed by the strategy include stock holding levels, lead time minimization and reduction of stock holding costs for the company. Lower costs will enhance our ability to offer better prices than competition giving us a cost leadership competitive edge. Efficiency and effectiveness of sourcing and the elimination of waste in our goods inwards processes is also key in breaking the quality cost trade off which is central to securing a blue ocean space in the industry.

The automotive industry continues to grow every day. Companies are always coming out with new technology for cars to better their product. In order for these companies to keep a competitive advantage they most implement different types of manufacturing processes. One of these manufacturing processes is lean manufacturing. Sundar, Balaji and Satheesh have done research on lean manufacturing, and they define it as the elimination of waste by determining value added activities and non-value added activities. Non-value added activities consist of transportation, inventory, motion waiting, overproduction, over processing, and defects (2014). Elmoselhy has found multiple tools to be used to implement lean manufacturing. Some of these tools are: 5S, Value Stream Mapping, Single Minute Exchange Die, Kaizen, and Autonomation. This list does not include all of the possible ways to implement lean manufacturing, but gives a brief introduction to a couple. The 5S stands for Sorting, Setting, Shining, Standardizing, and Sustaining (2013). This paper will discuss one of the five S’s, which will be standardizing. Also, this paper will also go into detail about how an automotive manufacturing company uses Single Minute Exchange Die, and some other aspects of lean manufacturing such as visual control and environmental management. Because lean manufacturing can be implemented in many different ways this paper

Production managers are faced with many challenges within their facilities such as managing inventories, controlling waste, and managing an ever changing production schedule. Managing product flows can be difficult when balancing supply chain inventories with demand changes or scheduling problems due to throughput variations. Several methods for managing these challenges have been developed through the years and each have their own advantages and disadvantages for different applications. The methods discussed in this paper will be limited to the Theory of Constraints, Just in Time, and Material Requirements Planning. All three methods are designed to manage different aspects of a manufacturing facility’s product flow but all three were ultimately developed as an optimization strategy for the manufacturing process. The roots of Lean Manufacturing is one of the earliest management strategies to be developed to address the challenges for production control and may well have been the birth of strategic production control as we know it today.

Just as with Lean Manufacturing, Lean Construction focuses on establishing value, as defined by the customer, it with the goal of constructing a product that delivers on that value. Thus, value must come before planning and design. (Mohammed).
