The assembly line feeding problem (abbr. ALFP) describes a problem in operations management concerned with finding the optimal way of feeding parts to assembly stations. [1] For this, various cost elements may be taken into account and every part is assigned to a policy, i.e., a way of feeding parts to an assembly line. The most common policies ...
All work in production line is stopped until a solution has been found. The alerts may be logged to a database so that they can be studied as part of a continual improvement process. Once the problem is troubleshot and fixed, a second pull of the andon cord authorizes the production to be resumed.
A feeder line is a secondary assembly line which provides parts for use in a primary assembly line. Researchers assert that the traditional level scheduling methodology of assembly line planning is not effective unless feeder lines provide parts to the primary assembly line.
An assembly line, often called progressive assembly, is a manufacturing process where the unfinished product moves in a direct line from workstation to workstation, with parts added in sequence until the final product is completed. By mechanically moving parts to workstations and transferring the unfinished product from one workstation to ...
In manufacturing engineering, a product layout refers to a production system where the work stations and equipment are located along the line of production, as with assembly lines. Usually, work units are moved along line (not necessarily a geometric line, but a set of interconnected work stations) by a conveyor. Work is done in small amounts ...
Design Rules: Foundries provide detailed design rules that specify minimum dimensions, spacing, and other geometrical constraints that must be adhered to for successful fabrication. DFM-aware design tools automatically check designs against these rules, flagging potential violations for correction.
After the cells had taken over the full production sequence (mechanical assembly, wave solder, thermal cycle, and conformal coat), cycle time had fallen to 30.5 weeks, of which production manager John Reiss attributed 20 weeks to use of a "WIP chart system" by the cell teams and the other 10.5 weeks to the cellular organization itself.
Production scheduling tools greatly outperform older manual scheduling methods. These provide the production scheduler with powerful graphical interfaces which can be used to visually optimize real-time work loads in various stages of production, and pattern recognition allows the software to automatically create scheduling opportunities which ...
