Optimization Means Higher Profits

One way or another, every manufacturer must solve a basic optimization problem—how to produce the most valuable product at the least possible cost. Particularly in high volume, low margin industries like petrochemicals and consumer products, profits depend on squeezing every bit of finished product out of the available raw materials and saving every dime on labor and material costs.

Process simulator aids testing and training

Legend has it that certain divinely inspired engineers in the automation industry are capable of producing bug-free control code on the first pass. Their programs always work as intended the first time the control system is powered up. I am certainly not one of them.My programs inevitably fail to account for some unforeseen sequence of events or some combination of inputs that only happen...

Structured programming tools for embedded systems

Sometimes it's fun to imagine what the world might have been like if John von Neumann had a room full of Crays or if Galileo had the Hubble telescope. On a somewhat smaller scale I wonder what my own career might have been like if I'd had something besides machine code back in the days of designing embedded control systems for microwave ovens, simple RTUs, and steam-driven chiller packages.

Software Still a Control ‘Hit’

Data acquisition software is hardly a "new kid on the block." The commercial use of software-configured control systems dates back to the 1970s, when the first large-scale proprietary control systems debuted. As the control industry has evolved, so have software-based systems.With the evolution of the personal computer and the networks on which they "reside," software developers are produ...

Simulation Simplifies ‘What-If’ Analysis

Whenever a new control system is proposed for an automated plant, a manager, engineer, or operator invariably asks how the system will react to certain events or conditions in the plant. What happens when the ambient temperature drops below freezing? What will the control system do if the conveyor suddenly stops? Will the robot arm be able to squeeze through that opening with a part in it...
