Discrete manufacturing varies from Process Manufacturing. In discrete manufacturing, the manufacturing floor works off orders to build something. Examples include toys, medical equipment, computers and cars. The resulting products are easily identifiable. In process manufacturing, the products are undifferentiated, for example oil, natural gas and salt.
Discrete manufacturing is often characterized by individual or separate unit production. Units can be produced in low volume with very high complexity or high volumes of low complexity. Low volume/high complexity production results in the need for an extremely flexible manufacturing system that can improve quality and time-to-market speed while cutting costs. High volume/low complexity production puts high premiums on inventory controls, lead times and reducing or limiting materials costs and waste.
Industry Profile - Discrete Manufacturing includes makers of consumer electronics, computer and accessories, appliances, and other household items, as well as "big ticket” consumer and commercial goods like cars and airplanes. Discrete Manufacturing companies make physical products that go directly to businesses and consumers, and assemblies that are used by other manufacturers.
The processes deployed in discrete manufacturing are not continuous in nature. Each process can be individually started or stopped and can be run at varying production rates. The final product may be produced out of single or multiple inputs. Producing a steel structure will need only one type of raw material - steel. Producing a mobile phone requires many different inputs, The plastic case, LCD display, the mainboard, PVC keypad, sockets, cables are made from different materials, at different places. This is different from Process manufacturing like production of paper or petroleum refining, where the end product is obtained by a continuous process or a set of continuous processes. Discrete manufacturing process allows for temporary stoppage of work in one area without affecting the entire unit, whereas continuous process manufacturing requires that entire production process be stopped.
Famous quotes containing the word discrete:
“We have good reason to believe that memories of early childhood do not persist in consciousness because of the absence or fragmentary character of language covering this period. Words serve as fixatives for mental images. . . . Even at the end of the second year of life when word tags exist for a number of objects in the child’s life, these words are discrete and do not yet bind together the parts of an experience or organize them in a way that can produce a coherent memory.”
—Selma H. Fraiberg (20th century)
