Lean System Essay

slender is a philosophy of manufacturing that emphasizes the minimization of the substance of entirely resources (including meter) apply in operations of the company. Operations processes be considered to be Lean when they argon very efficient and have few witless resources. The elimination of WASTE is actually the defining principle of Lean. By eliminating eat of all sorts in the system, the melt down approach lowers labour, materials, and energy make ups of production. Lean overly emphasizes build exactly the products nodes want, exactly when they need them. When lean capabilities argon introduced in a firm, it can produce smaller quantities, and it can veer outputs more quickly in repartee to changes in customer hold. The primary winding objectives of Lean systems are to1. Produce only the products that customers want.2. Produce products only as quickly as customers want them.3. Produce products with perfect quality.4. Produce in the minimum possible lead-times.5 . Produce products with features that customers want, and no others.6. Produce with no thriftlessness of labour, materials or equipment.7. Produce with methods that reinforce the occupational development of practises. Eliminate yenWaste is anything that does not add value from the customer point of view. Storage, inspection, delay, time lag in queues, and defective products do not add value and are 100% waste. Seven Wastes Overproduction, Queues, Transportation, Inventory, Motion, Over-processing and Defective products. Other resources such as energy, water, and send off are often wasted. Efficient, sustainable production minimizes inputs, curbs waste. Traditional ho dropkeeping has been grow to the 7 Ss. Sort when in doubt, throw it out. Simplify methods analysis tools. shine/sweep clean daily. Standardize remove variations from processes. Sustain review work and recognize progress. Safety build in good practices. Support/ victuals reduce variability and unplanned do wntime.There are four building blocks that contribute to the building of a lean system. When these elements are focused in the areas of cost, quality anddelivery, this forms the basis for a lean production system. They are1. intersection point design2. Process design3. Personnel/ systemal elements4. Manufacturing planning and dictationProduct design Each process is crucial and contributes to an effectual lean system. Product design consists of standard part (actors have fewer parts to deal with), modular design (an extension of standard parts, they are crystalize parts clustered together and treated as one unit), extremely able-bodied production systems with quality built in ( JIT requires highly capable production systems), and concurrent applied science (keeping engineering practices shouldnt change to invalidate disruptions).The fact that customers have unique needs makes it necessary for the producer in the manufacturing sector or the service sector to realize produc ts and services that contributes uniquely to the final customers requirements. All design activities have motion objectives that are important to all designs. These objectives are A design should be of high quality it should be produced quickly, on a dependent basis, tractableness and at a low cost.The three broad design categories, 1) the feasibility of the design, 2) the acceptability of the design, and 3) the vulnerability of each design option. Concurrent engineering-describes the process of incarnate product design by all affected functions in the organisation. character reference function deployment is a planning tool used to fulfil customer expectations through a disciplined approach to product design engineering and production. Process Design consists of small lot sizes (optimal one unit), setup time reductions, and manufacturing cells (specialized and efficient production centres, quality improvement, production flexibility, a balanced system (distributing workload e venly among the workstations), little schedule storage, and fail safe methods (incorporate ship canal to reduce or eliminate the potential for errors during the process). Lean systems have an extremely effective production method. Schedules must be communicated inside and outside the organization and Better scheduling improves performance and also Increases flexibility.Personnel/organizational elements includes workersas assets ( A JIT philosophy), Cross-trained workers (perform several parts of the process and operate several machines), cost accounting, and leadership/project management( a two-way communication process betwixt managers and workers). Manufacturing planning and control The last building block is manufacturing planning and control. It includes level loading,(achieving stable, level daily mix schedules) pull systems (work moves on in response to demand from the next stage in the process), visual systems (A kanban card used as authorization to move or work on parts), special(a) work-in-process, close vendor relationships, reduce transaction processing(logistical, balancing, quality, or change transactions), onus of importtenance and housekeeping(keeping the workplace clean and free of unneeded material. Improve employee communication. Identifying problems and capricious out waste reduces costs and variability and improves throughput. Lean systems require managers to reduce variability caused by both internal and external factors. By force material in small lots, inventory cushions are removed exposing problems and evince continual improvement.ExampleLean operations began as lean manufacturing which was demonstrable by the automobile manufacturer, Toyota. Toyota was sensitive to waste and inefficiency issues. The goal was to eliminate all waste from the process. Waste was identified by them as anything that interfered with the process or simply did not add value. Companies began adopting the lean approach and to do so realized that they h ad to do major changes in their organization and with their culture in the organization. Lean methods have demand-based operations, flexible operations with rapid changeover capability, effective worker behaviors, and continuous improvement efforts.JIT system stands for a Just-In-Time system. It represents the philosophy that includes both aspect of the process from the design to after the sale. JIT is a highly set up processing system in which goods move through the system, and services are performed just as they are needed. First, management should decide if JIT is a congruous method for the company. JIT is best used with companies that have repetitive operations and a stable demand. The first footstep is planning the conversion to JIT. Managers need tobe involved in the process and understand the commitment needed. The next step is to begin working only with suppliers who support the JIT system.The biggest obstacles faced are management, worker or supplier disapproval, and al so changing the culture of the company. Inventory is at the minimum level necessary to keep operations running. JIT Inventory manoeuvre Use a pull system to move inventory clip lot sizes Develop just-in-time delivery systems with suppliers Deliver directly to point of use Perform to schedule Reduce setup time Use root technology. Different from JIT in that it is externally focused on the customer Starts with perceptiveness what the customer wants Optimize the entire process from the customers perspective. The main benefits of lean operations systems are1. Reduced cost through reduced inventory levels2. Higher quality3. Reduced lead time4. increase productivity5. Reduced amounts of wasteInventories should never be used as the solution to fix machine malfunctions. One method that JIT systems uses to minimize inventory is to have suppliers deliver goods directly to the production floor. Overall, carrying low inventories offers many benefits such as less carrying cost, less space nee ded, and less rework to get it on in case of a product recall. Lean systems can also be referred to as just-in-time (JIT) systems. The object of a lean system is to create a system that is demand driven, and provides supply based on demand at any given point. Lean systems tend to concentrate on waste reduction and have continuous improvement.
