Discretemanufacturing varies from Process manufacturing Process Manufacturing . In discretemanufacturing, the manufacturing floor works off orders to build something. Examples include toy s, medical equipment , computer s and car s. The resulting products are easily identifiable. In process manufacturing, the products are undifferentiated, for example oil , natural gas and salt . Discretemanufacturing 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 control s, lead time s and reducing or limiting materials costs and waste. blockquote Industry Profile DiscreteManufacturing includes makers of consumer electronics, computers and accessories, appliances, and other household items, as well as big ticket consumer and commercial goods like cars and airplanes.

A discrete system is a system with a countable number of states. Discrete systems may be contrasted with continuous systems, which may also be called analog systems. A final discrete system is often modeled with a directed graph mathematics graph and is analyzed for correctness and complexity according to computational theory . Because discrete systems have a countable number of states, they may be described in precise mathematical models . A computer is a finite state machine that may be viewed as a discrete system. Because computers are often used to model not only other discrete systems but continuous systems as well, methods have been developed to represent real world continuous systems as discrete systems. One such method involves sampling a continuous signal at discrete time intervals.

In mathematics , especially category theory , a discrete category is a category whose only morphism s are the identity morphism s. It is the simplest kind of category. Specifically a category C is discrete if hom sub C sub X , X id sub X sub for all objects X hom sub C sub X , Y for all objects X Y Since by axioms, there is always the identity morphism between the same object, the above is equivalent to saying hom sub C sub X , Y is 1 when X Y and 0 when X is not equal to Y . Clearly, any class set theory class of objects defines a discrete category when augmented with identity maps. Any subcategory of a discrete category is discrete. Also, a category is discrete if and only if all of its subcategories are full category full . The limit category theory limit of any functor from a discrete category into another category is called a product category theory product , while the colimit is called a coproduct .

Unreferenced date December 2009 For a mathematically rigorous point of view of discrete spectrum , see decomposition of spectrum functional analysis .
