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.

The current economic environment we are in, shared with increasing guidelines has placed manufacturers in the challenging position of having to reduce waste, improve processes, and increase productivity. Although lean manufacturing can well enough be the answer, some companies have found lean manufacturing implementation to be an ongoing battle. Which is not to say, however, that there have not been some major success stories. There are many obstacles to lean implementations.

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

Lean Principles in manufacturing can improve operating performance by focusing on the uninterrupted flow of products and materials

In operations management beyond the stars proposes lean manufacturing as the basic production philosophy. This is envisioned to reduce waste in the form of

Lean suggests the need for the supply chain to exploit the limited resources for an efficient completion of the job. Inventory, trucks warehouses, laborers and the capital for working are the primary sources in the supply chain (Myerson, 2012). The lean supply chain is designed to include inventories in the framework, warehousing space that is minimal to keep these inventories. It will also design to the establishment of long term, supply contracts that are stable with a negotiated cost that is low, typically without any substantial ability to alter ordered quantities.it will also design the destination of delivery and design the date required after there is an order placed. All these factors will minimize the supply chain cost operations making it efficient in cost and will constrain the ability of supply chain for the adaptation of any demand and supply changes. The supply chains should manage variability and an exclusive aim on lean that prevents supply chains to design an effective to manage the natural variability and then from doing the work that are important to them. At many cooperations, they have several products to manage where these products vary widely in demand and lead time patterns, the supply chain enterprise should be designed to work on

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.
