Production control Wikipedia

Overview. Production control is the activity of monitoring and controlling a large physical facility or physically dispersed service. It is a "set of actions and decision taken during production to regulate output and obtain reasonable assurance that the specification will be met." The American Production and Inventory Control Society, nowadays APICS, defined production control in 1959 as:

A dynamic mathematical model was developed for the simulation and control of cement rotary kilns. The model consists of a set of nonlinear partial differential equations, and represents the material and energy balances in the kiln.

Controlling cement hydration with nanoparticles

In our study we showed that it is possible to control the kinetics of cement hydration in many different ways by the addition of nanoparticles. SiO 2 particles show typical characteristics of a cement hardening accelerator.
