Processor captive

The two processors are delivering the product via pipes into one of several tanks in a tank farm. Each tank has parameters such as capacity or cleaning time. From the tanks the product is either delivered to processes on site (captive use) or to customers based on given customer orders. Additionally, it may be stored in two external buffers. In that case there are transportation moves from the tank farm to one of the external buffers (in case of over-production) or from the external buffer to the tank farm (in case of shortages in production) induced. 

Captive processors, who possess in-house production facilities they are usually manufacturers that consume large volumes of polymer parts... 

Processors cover a wide range— from tiny, "garage shops" to billion-dol-lar multinational companies, from custom parts producers to original-equipment manufacturers captive operations. They include specialists in different types of processing, in particular, classes of materials, specific types of parts or industries, etc. Some just pass plastic through a machine, some also make molds, others also decorate parts and assemble them. Some have become complete "contract manufacturers," with an emphasis on plastics. However, there are key factors that apply to each of these diversified entities. 

Processors expense allocations can vary even more widely than those of distributors, depending on their size, the extent to which their operations are fully integrated, and whether they do custom, proprietary, captive work, or some combination of the foregoing. The following example is for a custom injection molder and assumes smaller size and limited integration, for example, mold maintenance, but not mold building, assembly but not decorating, etc.
