Operations Management

Notes With increasing pressure on manufacturing flexibility to meet customer needs, there has
been a move towards new forms of assembly lines, e.g., mixed model lines.

There are a few other service layouts which are prevalent and some are fast emerging:
warehouse layout, retail layout and office layout.
After a layout is chosen and designed and activities are defined and their requirements,
developed, the next step is to define the relationships between activities which is called
closeness rating.

Assembly Line: Production follows in a predetermined sequence of steps, which are continuous
rather than discrete.

Cell: Self-sufficient unit in which all operations required to make components or complete
products can be carried out.
Closeness Rating: Relationships between activities in a layout.

CIM: Complete automation of a manufacturing plant
CRAFT: Computerized Relative Allocation of Facilities Technique
Cycle Time: Time period after which completed units come off the assembly line.

Fixed Position Layout: Material remains fixed and tools, machinery and men are brought to the
location of the material.
Flexible Manufacturing: Ability of a manufacturing system to respond at a reasonable cost and
at an appropriate speed.
Group Layout: Combination of both process and product layout and incorporates the strong
points of both of these.

Mixed Layout: Produces several items belonging to the same family.
Office Layout: Based on the interrelationships among employees, flow of work through the
various work units, and equipment.

Part Family: Manufacturing operations grouped into one family.
Process Layout: Similar machines or similar operations are located at one place as per the
functions

Product Layout: Facilities are located based on the sequence of operation on parts.
