CELLULAR MANUFACTURING: ONE-PIECE FLOW FOR WORKTEAMS PDF, EPUB, EBOOK Productivity Development Team | 86 pages | 05 Mar 1999 | Taylor & Francis Inc | 9781563272134 | English | Portland, United States Cellular Manufacturing: One-Piece Flow for Workteams - Productivity Development Team - Google Books Browse All Regulations. I'm looking for support for Other Glossary Terms. The concept of cellular manufacturing is an important component for both JIT manufacturing and Lean organizations. It is a process used to support and facilitate one-piece flow in production by having equipment, workstations, and cells arranged in order of processes to produce a single or very small batch of products. Traditionally in manufacturing, similar machines are placed near each other with parts being processed and moved between different departments in large batches. This can lead to unexpected breakdowns, piled up inventory, and unnecessary motion, resulting in valuable resources waste. On the other hand, a cellular layout operates on the pull system with products being made only as they are demanded and in very small batches. The production line is comprised of multiple cells sequenced in the order of operations and the work cells themselves are then placed near each other to save space and reduce unnecessary movement while streamlining the flow. For example, the department receiving the raw materials inventory can be placed at one end of the facility and the first value-added process is in a work cell right next to the department. From there, products move from cell to cell, with one part of the manufacturing process being completed within each cell. The finished product ends up at the shipping department, which would be opposite to the receiving department in a U-shaped layout. Be the first to like this. No Downloads. Views Total views.

Cellular manufacturing one piece flow for workteams by Standards Media - Issuu There are various commonly used designs that can be appropriate in different circumstances, and they mostly determine the shape of the manufacturing chain. The key benefit of a properly designed cell is that it reduces floor space, reduces delays and hand-offs within the value stream, and improves communication between process steps. Implementing cellular manufacturing begins by splitting the production process down into sensible steps. Note that this does not mean breaking it down into the most fundamental, basic steps, but rather to organize the various steps into sensible groups according to the complexity of the tasks involved, and the need for communication between separate units. Ideally, a Value Stream Map should be created, showing all the steps required to create value for the customer, based on the product or service they are requesting from your company. If the sub components are not supplied, but manufactured within the facility, they might be incorporated into the cell, or they could be assigned to their own cell. It depends how much of the sub component is used in other cells within the facility. If it only goes to the one final product, then it should be included in the cell. Choosing the right layout is just as important as splitting the cells correctly in the first place. There are multiple different commonly used layouts to choose from, and with some creativity, you may even be able to come up with your own. The important thing is that you weigh the benefits and disadvantages of each common layout according to your own situation. Remember to regularly revise the design of your cellular manufacturing plant, and think about alternatives that can improve the production flow. After all, one of the core concepts of lean manufacturing is constant improvement, and cellular manufacturing is no exception. In a positive way, cross training will allow them to take on more work. On the negative side, you might be replacing experienced employees, and less can be done by each employee. The shape will need to change to reflect the current experience level. Cellular manufacturing is a natural result of the desire to think analytically and break down processes into simple components that can be easily analyzed, exchanged and reorganized.

What is Andon cord? What is Poka Yoke? What is Kaizen? It is for this reason that the one-piece-flow cell has been called "the ultimate in lean production. Cellular manufacturing is derivative of principles of group technology, which were proposed by Flanders in [2] and adopted in Russia by Mitrofanov in whose book [3] was translated into English in Burbidge actively promoted group technology in the s. By cells had come to be treated as foundation practices in JIT manufacturing, so much so that Harmon and Peterson, in their book, Reinventing the Factory , included a section entitled, "Cell: Fundamental Factory of the Future". Cells are created in a workplace to facilitate flow. This is accomplished by bringing together operations or machines or people involved in a processing sequence of a products natural flow and grouping them close to one another, distinct from other groups. This grouping is called a cell. These cells are used to improve many factors in a manufacturing setting by allowing one-piece flow to occur. First, the pieces would be moved from storage to the cell, where they would be welded together, then polished, then coated, and finally packaged. Some common formats of single cells are: the U-shape good for communication and quick movement of workers , the straight line, or the L-shape. The number of workers inside these formations depend on current demand and can be modulated to increase or decrease production. For example, if a cell is normally occupied by two workers and demand is doubled, four workers should be placed in the cell. Similarly, if demand halves, one worker will occupy the cell. Since cells have a variety of differing equipment, it is therefore a requirement that any employee is skilled at multiple processes. While there exist many advantages to forming cells, there are some obvious benefits. It is quickly evident from observation of cells where inefficiencies lie, such as when an employee is too busy or relatively inactive. When formation of a cell would be too difficult, a simple principle is applied in order to improve efficiencies and flow, that is, to perform processes in a specific location and gather materials to that point at a rate dictated by an average of customer demand this rate is called the takt time. This is referred to as the Pacemaker Process. Despite the advantages of designing for one-piece-flow, the formation of a cell must be carefully considered before implementation. Use of costly and complex equipment that tends to break down can cause massive delays in the production and will ruin output until they can be brought back online. Manufacturing cells [closely locate] people and equipment required for processing families of like products. After reorganization, families of similar parts are produced together within the physical confines of cells that house most or all of the required resources, Furthermore, cell operators can be cross-trained in several machines, engage in job rotation, and assume responsibilities for tasks [that] previously belonged to supervisors and support staff [including] activities such as planning and scheduling, quality control, trouble-shooting, parts ordering, interfacing with customers and suppliers, and record-keeping. The short travel distances within cells serve to quicken the flows. Moreover, the compactness of a cell minimizes space that might allow build-ups of inventory between cell stations. To formalize that advantage, cells often have designed-in rules or physical devices that limit the amount of inventory between stations. Discussion and illustrations of cells in combinations with kanban are found in [12] The simplest form, kanban squares, are marked areas on floors or tables between work stations. The rule, applied to the producing station: "If all squares are full, stop. If not, fill them up. An office cell applies the same ideas: clusters of broadly trained cell-team members that, in concert, quickly handle all of the processing for a family of services or customers. A virtual cell is a variation in which all cell resources are not brought together in a physical space. In a virtual cell, as in the standard model, team members and their equipment are dedicated to a family of products or services. Although people and equipment are physically dispersed, as in a job shop, their narrow product focus aims for and achieves quick throughput, with all its advantages, just as if the equipment were moved into a cellular cluster.
