implementation of cellular manufacturingjoe's original dartmouth menu

So they are supposed to learn to perform a more oversight and support role, and maintain a system where work cells self-optimize through supplier-input-process-output-customer (SIPOC) relationships.Product start-ups can be more difficult to manage if assembly training was traditionally accomplished station-by-station on a fixed assembly line. Thus, the breakdown of one cell, due to equipment malfunction or staffing problems, does not radically affect the rest of the production process.Technology and cellular manufacturing have combined to streamline the production processes of numerous established and start-up manufacturing facilities worldwide. In many cases, workers from the affected processes participate in the conversion process. The figure to the right illustrates the flow in a cellular production environment, where parts are pulled into the system as signaled by customer demand. To make the cellular design work, an organization must often replace large, high volume production machines with small, flexible, "right-sized" machines to fit well in the cell.

The consideration of the cell’s internal group dynamics, personalities and other traits is often more of a concern in cellular manufacturing due to the closer proximity and co-dependency of the team members; however properly implemented this is a major benefit of cellular manufacturing.Along with the set up costs, there are also other costs associated with particular cells in cellular manufacturing. Each of the workers in each cell should ideally be able to complete the entire range of tasks required from that cell, and often this means being more multi-skilled than they were previously. Family of parts is the process of grouping workpieces into logical families so that they can be produced by the same group of machines, tooling, and people with only minor changes on procedure or setup.In production, setups and changeovers are faster because the same tools and fixtures can be used for similar parts. The costs of work stoppages during implementation can be considerable, and generally this rearrangement is preferred to be phased to minimize the impacts of such disruptions as much as possible.The soft issues are more difficult to calculate and control.

In many instances this system can be highly inefficient and wasteful.

Also, this will help in reducing stalling time and will increase the capacity.Once the new cell is tested and ready for production, the incoming parts to and outgoing parts from the old cell will simply be rerouted to the new cell without having to disrupt the entire production line.In this way, work cells increase the flexibility to upgrade processes and allow changes in products to better suit customer demands while reducing or eliminating the costs of breakdown. Cellular Manufacturing  is a model for workplace  design, and is an integral part of  lean manufacturing  systems. Thus, all parts basically follow the same routing with some minor variations (e.g., skipping an operation).

Primarily, this is due to substantial "work-in-process", or WIP, being placed on hold while other functional departments complete their units, as well as the carrying costs and building space associated with built-up WIP on the factory floor.

The goal of lean manufacturing is the aggressive minimization of waste, called  muda, to achieve maximum efficiency of resources. In this way, a large variety of automobiles, with different performances and appearances and functions, can be produced by combining the outputs from a more limited number of work cells.Cells are usually larger than traditional workstations, but smaller than a complete department. Method and Implementation Approach Cellular manufacturing requires a fundamental paradigm shift from "batch and queue" mass production to production systems based on a product aligned "one-piece flow, pull production" system. This means that a large variety of products can be designed to be assembled from a small number of modular parts, through which a high product variety as well as high productivity can be achieved.

Even though the machinery may be functionally dissimilar, the family of parts produced contains similar processing requirements or has structural similarities. As each operator in a cell is responsible for a larger number of assembled parts and operations, the time needed to master the sequence and techniques is considerably longer. Cells may be designed for the office as well as the factory.Though very technical and detailed, the concept of cellular production is basically simple; get a finished product from raw materials to shipment as efficiently, and as profitably as possible. Cellular Manufacturing is a model for workplace design, and has become an integral part of lean manufacturing systems and it is based upon the principles of Group Technology, which seeks to take full advantage of the similarity between parts, through standardization and common processing. The implementation of cell manufacturing often involves employee training and the redefinition and reassignment of jobs.

The process may be executed with the aid of a computer, and has been used to divide parts into groups for use with CAD/CAM processing.

Equipment often must be modified to stop and signal when a cycle is complete or when problems occur, using a technique called autonomation (or This transformation often shifts worker responsibilities from watching a single machine, to managing multiple machines in a production cell. The parts make their way through the various functional departments in large "lots", until the assembled products eventually are shipped to the customer.To enable a smooth conversion, it is typically necessary to evaluate the machines, equipment, and workstations for movability and adaptability, then develop a conversion plan.
