Required information Meeting the Goals of Lean Operations Meeting the Goals of Lean Operations A lean operation is a flexible system of operation that uses considerably fewer resources (i.e. activities, people, inventory, and floor space) than a traditional system. Moreover, lean systems tend to achieve greater productivity, lower costs, shorter cycle times, and higher quality than nonlean systems. Lean systems are sometimes referred to as just-in-time (JIT) systems owing to their highly coordinated activities and delivery of goods that occur just as they are needed. Lean/JIT represents a philosophy that encompasses every aspect of the process, from design to after the sale of a product. The philosophy is to pursue a system that functions well with minimal levels of inventories, minimal waste, minimal space, and minimal transactions. It must be a system that is not prone to disruptions and is flexible in terms of the product variety and range of volume that it can handle. The ultimate goal of a lean operation is to achieve a system in which supply is synchronized to meet customer demand in a smooth, uninterrupted flow. The ultimate goal of lean is a balanced system, that is, one that achieves a smooth, rapid flow of materials and/or work through the system. The idea is to make the process time as short as possible by using resources in the best possible way. The degree to which the overall goal is achieved depends on how well supporting goals are achieved. Those goals are to 1. Eliminate disruptions 2. Make the system flexible 3. Eliminate waste, especially excess inventory The items listed below each contribute to one or more of the The items listed below each contribute to one or more of the supporting goals of lean systems.

Single minute exchange of die ( SMED)

Following definitions are relevant for the classification done above :

Preventive maintenance (or preventative maintenance) is maintenance that is regularly performed on a piece of equipment to lessen the likelihood of it failing. Preventive maintenance is performed while the equipment is still working, so that it does not break down unexpectedly. Thus main purpose of preventive maintenance is to avoid disruption

Value stream mapping is a flowchart method to illustrate, analyze and improve the steps required to deliver a product or service. A key part of lean methodology, VSM reviews the flow of process steps and information from origin to delivery to the customer. As with other types of flowcharts, it uses a system of symbols to depict various work activities and information flows. VSM is especially useful to find and eliminate waste. Items are mapped as adding value or not adding value from the customer’s standpoint, with the purpose of rooting out items that don’t add value.

Level Loading, also referred to as production leveling, refers to the balanced throughput rates of activities within a process. Balancing a process reduces the non-value added portion of the process cycle time, and removes the waste of items in queue.

Manufacturing cell :A manufacturing cell is an efficient grouping of all the resources required to manufacture a product. These resources, which usually include people, supplies, machines, tools and other production equipment, are arranged in close proximity to enhance communication and allow everyone to see what is going on at all times.

Cellular manufacturing is a tried and true process that has reduced product costs, while improving leadtimes and quality. Cells have prospered because they work, and they work in almost any type of manufacturing environment. One reason cells are successful is that they often eliminate many of the wastes inherent in a typical manufacturing operation.

Single-minute exchange of die (SMED) is one of the many lean production methods for reducing waste in a manufacturing process. It provides a rapid and efficient way of converting a manufacturing process from running the current product to running the next product. This rapid changeover is key to reducing production lot sizes and thereby improving flow (Mura), reducing production loss and output variability.[1]
