There are numerous parts in any assembly. Increases the machine down time as machines are grouped as cells which may not be functional throughout the production process.Ī classification system can be used to easily follow a GT technique.Involves less manufacturing flexibility.Difficulties with out-of-cell operations.The rate of change in product range and mix.The Additional cost of implementation of this system.This technique, along with good general management practices, therefore has a large contribution towards improving productivity in general and reducing inventory cost in particular. Robots can be easily used for material handling. The flow of the operations transformed resources Process type Basic layout type.Smaller variety of tools, jigs and fixtures.Output is improved due to improved resource utilization.Simplified estimating, accounting and work management.Reduction in planning cost and simplifying the documentation and administration of the process planning function.The next step in production planning is deciding on plant layout. Reduction in inventory cost and thus reduction of lot size. Describe four major types of facility layouts: process, product, cellular, and fixed position.Reduction in setting up times and cost.The generally accepted benefits of group technology are : Group technology is the process of creating groupings of products based on similar processing requirements. It has the advantage of bringing the efficiencies of a product layout to a process layout environment. One of the most popular types of hybrid layouts is group technology (GT) or cell layouts. It offers its greatest benefits when it is extended to all phases of production and production preparation including drafting and part programming for NC machine. Waiting time is reduced significantly and work center utilization in improved. Machines are grouped according to the routing required for aįamily of parts rather than by their functions.īy using this technique, production planning and control functions are also simplified as the group of machines can be treated as one work center, thereby decreasing the number of work centers and simplifying the routing of parts. Instead, there is an assembly of similar operations or similar machinery in each department (for example, a drill department, a paint department, etc. This technique identifies the sameness of parts, equipment or processes. In process layout, the work stations and machinery are not arranged according to a particular production sequence. Group technology is an important technique in the planning of manufacture that allows the advantages of product line organization to be obtained in what otherwise would be jobbing or batch manufacture.
