Explain Discrete, Flow and Process manufacturing?

Discrete manufacturing: is distinguished by the production of distinct items that use bills of material and routings to determine costs and lead times.

Examples: Automobile manufacturing, computer manufacturing, dishwasher and washing machine manufacturing, etc.

Flow manufacturing: is also called Lean Manufacturing or JIT(Just-In-Time) and uses the principles of demand flow manufacturing to produce product is required, for customer orders, quickly and to meet the demand exactly on-time.

Usually, in order to use Flow a company needs to have production facilities that subscribe to the principals of Lean Manufacturing. It is necessary to design production facilities so that production lines, resources, machines, and labor are making only what is needed for immediate customer orders.

Process manufacturing: is distinguished by a production approach that has minimal interruptions in actual

processing in any one production run, or between production runs of similar products. This approach produces multiple unique products in relatively small batches flowing through different production operations throughout the factory.

They are normally producing a Product that is "Homogeneous" and equally divided for the convenience of packaging.

Typical examples are Food, pharmaceutical and other batched-based manufacturers such as refineries, wineries, etc.
