Interpenetrating Polymer Networks
Some special polymer materials can be produced when linear thermoplastic chains are intertwined through a thermosettin framework, forming interpenetrating polymer networks. For example, nylon,acetal and polypropylene chains can pentrate into a cross-linked silicone thermoset. In more advanced systems, two interpenetrating thermosetting framework structures can be produced.

Polygonized Subgrain Structure
The original cold-worked microstructure is composed of deformed grains containing a large number of tangled dislocations. When we first heat the metal, the additional thermal energy permits the dislocations to move and form the boundries of a polygonized subgrain structure.

TBO (Time Between Orders)
One way to reduce the high inventory carrying cost associated with fixed lot sizes is to use the economic order quantitiy formula to compute an economic time between orders(TBO). We do this by dividing the economic order quantitiy by the mean demand rate.

Statement Of Future Output
The master production schedule is a statement of planned future output. It specifies the products(or product options) that will be completed, the time of completion and the quantities to be completed. It is the anticipated build schedule fort he company. As such, it is a statement of production, not a statement of demand. The MPS specifies how product will be supplied to meet future demand. We stess the fact that the MPS is not a forecast, since manufacturing is held responsible for meeting the MPS requirements.
