Uneven production process in simulation inside production simulation game in Ford's Museum. Production leveling, also known as production smoothing or – by its Japanese original term – heijunka (平準化), [1] is a technique for reducing the mura (unevenness) which in turn reduces muda (waste).
Designing assembly lines is a well-established mathematical challenge, referred to as an assembly line balancing problem. [3] In the simple assembly line balancing problem the aim is to assign a set of tasks that need to be performed on the workpiece to a sequence of workstations. Each task requires a given task duration for completion.
Line balancing (or production leveling): the correct number of workstations for optimum work flow depends on the processing time, or standard, at each workstation. Materials requirement planning (MRP): MRP systems cannot operate properly without accurate work standards.
The line can synchronous, meaning that all parts advance with the same speed, or asynchronous, meaning buffers exist between stations where parts wait to be processed. Not all transfer lines must geometrically be straight lines, for example circular solutions have been developed which make use of rotary tables, however using buffers becomes ...
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 ...
There are plenty of good reasons to purchase a used car, truck, or SUV instead of buying a new vehicle.Chief among them is being able to avoid the dreaded D-word—depreciation—but you can also ...
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 ...
Takt time, or simply takt, is a manufacturing term to describe the required product assembly duration that is needed to match the demand.Often confused with cycle time, takt time is a tool used to design work and it measures the average time interval between the start of production of one unit and the start of production of the next unit when items are produced sequentially.
