Austenitic stainless steels (AISI316) are used for many commercial and industrial applications for their excellent corrosive resistance. AISI316 is generally difficult to machine material due to their high strength and high work hardening tendency. Tool wear (TW) and surface roughness (SR) are broadly considered the most challenging phases causing poor quality in machining. Optimization of cutt...

methyl tertiary butyl ether (mtbe) is known as a promising substitute for tetra ethyl lead (tel) in order to increase the octane number of gasoline. mtbe process, as many other processes, has two distinguished section, namely reaction section and separation section. in this paper we focus only on synthesis and optimization of separation section of this process. in order to achieve this objectiv...

Electrical machines are the hearts of many appliances, industrial equipment and systems. In the context of global sustainability, they must fulfill various requirements, not only physically and technologically but also environmentally. Therefore, their design optimization process becomes more and more complex as more engineering disciplines/domains and constraints are involved, such as electrom...

Equation Chapter 1 Section 1 Abstract— The concept of PID controllers (proportional integral derivative) belongs to the most frequently used principles of controlling in industrial and non-industrial applications. The process of setting of PID controller can be determined as optimization task. Requiring optimal settings of PID controller we can specify more goals of optimization which are ofte...

Dynamic optimization allows for the determination of the upper bound of achievable performance in the operation of continuous chemical processes in transient operationwhich often results from load or grade changes. Performance assessment can rely on the computation of optimal trajectories for selected scenarios which properly reflect the operational envelope. Realistic industrial problems, howe...

a new method is developed for a fast identification of the stability situation of industrial processes. the proposed method includes two factor ratios of the control constants for the upper and lower control limits to process these constants. an indication ratio is then defined as the ratio of the maximum data range value to the difference between the maximum and average values for individual d...

Industrial utility systems, traditionally the "poor forgotten cousin" of the processing industry, are now receiving the attention they deserve. While the thermodynamics and process models of utility systems are well established, the optimization of utility systems typically involves solving large-scale optimization problems including integer constraints, and hence are less commonly tackled. The...
