Fixed and variable costs are two types of expenses that affect the profitability and feasibility of a construction project. Knowing how to estimate, track, and control them is essential for any ...

Profitable and reliable operation depends on optimizing related process variables, which can be achieved by control room operators leveraging DCS domain knowledge and big data. By Yasunori Kobayashi.

Volumetric flow, flow velocity and temperature measurement – three of the most important variables which help to ensure efficient process control. So, wouldn’t it be convenient if you could measure ...

Material properties or product properties, production rate and production economics depend on composition variables, process variables and dimension variables, as summarized in Figure 3. Nonlinear ...

Single-loop control (i.e., a control loop with one input and one output) as implemented in various versions of the proportional, integral, derivative control algorithm in modern distributed control ...

2 Benefits and 1 Drawback of Key Process Input Variable. Understanding how to influence and control product or process variation with KPIVs is fundamental to the adoption of Six Sigma principles.

Next, I note an initial time, T1, and modify the control variable with a large step. I measure the time between my modification and when the process variable begins to respond or T2. The difference ...
