At present, many famous software companies have promoted the forecast control commercialization software package, and in profession promotion applications and so on the refinery, petrification, forecast the control has played the vital role in the process control domain. But the existing forecast control software is mostly inserting in the special-purpose platform which these famous software company develops, can use using the factory essential purchase specialized platform, the price is expensive, only obtained the limited promotion in our country, also in some situations from the software which overseas purchases is not suitable for the home production boundary condition change, cannot play its role fully. For this reason, we face the actual conditions of the industrial process of our country, the advancements of small-scale devices of Israel and China are controlled for the goal, have developed the common artificial software cont.
