not putting in a screw before drilling the hole) and (2) a cycle time which restricts the sum of task processing times which can be completed at each workstation before the work-piece is moved to the next station by the conveyor belt. The assignment of tasks to stations is typically limited by two constraints: (1) a precedence graph which indicates what other tasks need to be completed before a particular task can be initiated (e.g. Each task requires a given task duration for completion. 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.

ĭesigning assembly lines is a well-established mathematical challenge, referred to as an assembly line balancing problem. (3) Use sliding assembling lines by which the parts to be assembled are delivered at convenient distances. (2) Use work slides or some other form of the carrier so that when a workman completes his operation, he drops the part always in the same place-which place must always be the most convenient place to his hand-and if possible have gravity carry the part to the next workman for his own. (1) Place the tools and the men in the sequence of the operation so that each component part shall travel the least possible distance while in the process of finishing. Each worker typically performs one simple operation unless job rotation strategies are applied. Heavy lifting is done by machines such as overhead cranes or forklifts.

All parts or assemblies are handled either by conveyors or motorized vehicles such as forklifts, or gravity, with no manual trucking. The motion of workers is minimized to the extent possible.

Concepts Lotus Cars assembly line as of 2008Īssembly lines are designed for the sequential organization of workers, tools or machines, and parts.

Workers in charge of the works of assembly line are called assemblers. By mechanically moving the parts to the assembly work and moving the semi-finished assembly from work station to work station, a finished product can be assembled faster and with less labor than by having workers carry parts to a stationary piece for assembly.Īssembly lines are common methods of assembling complex items such as automobiles and other transportation equipment, household appliances and electronic goods. An Airbus A321 on final assembly line 3 in the Airbus Hamburg-Finkenwerder plant Hyundai's car assembly lineĪn assembly line is a manufacturing process (often called a progressive assembly) in which parts (usually interchangeable parts) are added as the semi-finished assembly moves from workstation to workstation where the parts are added in sequence until the final assembly is produced.
