Cellular manufacturing is a process of manufacturing which is a subsection of just-in-time manufacturing and lean manufacturing encompassing group technology.The goal of cellular manufacturing is to move as quickly as possible, make a wide variety of similar products, while making as little waste as possible.
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.
An example of a long-term bottleneck is when a machine is not efficient enough and as a result has a long queue. [2] An example is the lack of smelter and refinery supply which cause bottlenecks upstream. Another example is in a surface-mount technology board assembly line with several pieces
For example, UNIX derivatives may pipeline commands connecting various processes' standard IO, using the pipes implemented by the operating system. Some operating systems [ example needed ] may provide UNIX-like syntax to string several program runs in a pipeline, but implement the latter as simple serial execution, rather than true pipelining ...
Equations of synchronous and random servicing as well as line balancing are used to determine the ideal worker to machine ratio for the process or product chosen. Synchronous servicing is defined as the process where a machine is assigned to more than one operator, and the assigned operators and machine are occupied during the whole operating ...
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 application program interfaces of IBM's mainframe operating systems is defined as a set of assembly language "macro" instructions, that typically invoke Supervisor Call (SVC) [e.g., on z/OS] or Diagnose (DIAG) [on, e.g., z/VM] instructions to invoke operating system routines. It is possible to use operating system services from programs ...
