formats by which a facility is arranged are defined by ?
the general pattern of work flow and there are 5 basic structures
project layout
the product, because of its sheer bulk or weight remains fixed in a location. equipment is moved to the product rather than product moved to the equipment
5 basic structures
project layout
workcenter
manufacturing cell
assembly line
continuous process
workcenter
process structure suited for low-volume production of a great variety of nonstandard products. departments and are focused on a particular type of operation.
manufacturing cell
an area where simple items are similar in processing requirements are produced.
assembly line
process structure designed to make discrete parts. parts are moved through a set of specially designed workstations at a controlled rate
continuous process
an often automated process that converts raw materials into a finished product in one continuous process
product-process matrix
shows the relationship between different production units and how they are used depending on product volume and the degree of product standardization
break-even analysis
standard approach to choosing among alternative processes or equipment; presents alternative profits and losses due to the number of units being sold
process flow design components (4)
assembly drawing, assembly chart, operation and route sheet, process flowchart
manufacturing process flow design
method to evaluate the specific processes that raw materials, parts and subassemblies follow as they move through the plant
assembly drawing
exploded view of the product showing its component parts
assembly charts
uses the information presented in the assembly drawing and defines how parts go together, their order of assembly ad often overall material flow pattern
operation and route sheet
specifies operations and process routing for a particular part
process flowchart
what happens to the product as it progresses through the productive facility; eliminate/minimize unneeded activities
