Struvite crystallization using fluidized bed reactors (FBRs) is one of the most commonly used methods for nutrient recovery from different waste streams. However, struvite recovery from swine wastewater containing much higher solids using FBR has not been studied extensively. In this study, we therefore designed and optimized the key operating conditions parameters, i.e., pH . Processes, an international, peer-reviewed Open Access journal. Dear Colleagues, Chemical Process Design, Simulation and Optimization constitute the core of the activity of chemical process engineers, process developers and designers, process economic evaluators, energy engineers and researchers implicated in chemical engineering.. This Special Issue explores the design . An efficient robust design optimization (RBO) framework is developed for linear multi-degree-of-freedom (MDOF) structural systems subject to evolutionary stochastic earthquake excitations. A significant feature of the developed RBO framework relates to the consideration of both inter-storey drift and floor acceleration second-order statistics. then (MO) will be a linear multiple-criteria optimization problem; otherwise, it is non-linear. For instance, in a financial application we may need, to maximize revenue and minimize risk at the same time, constrained upon the amount of our investment. Several engineering design problems can also be modeled into (MO).

Development of new methodologies for these two distinct problems in design optimization under uncertainty, explicitly considering risk and applying the newly developed techniques in engineering including civil, chemical, electrical, environmental and financial engineering problems is our main objective.

Risk is inherent in engineering All engineering involves risk. Innovation in design generally increases risk. More generally, any change (from proven practice) will often increase risk.

Chapter 1: Optimization-Based Design 1 CHAPTER 1 INTRODUCTION TO OPTIMIZATION-BASED DESIGN 1. What is Optimization. Engineering is a profession whereby principles of nature are applied to build useful objects. A mechanical engineer designs a new engine, or a car suspension or a robot.

A civil engineer designs a bridge or a Size: 2MB. Risk relates to a combination of the likelihood of occurring hazards, and to the severity of their outcome or consequence. Safety in engineering design begins with identifying possible hazards that could occur, as well as the corresponding system states that could lead to an accident or incident in the designed system.

On Structural Design Optimization under Uncertainty and Risk. In this paper, the effects of uncertainty and risk on structural design optimization are investigated, by comparing results of Deterministic Design Optimization (DDO), Reliability-based Design Optimization (RBDO) and Reliability-based Risk Optimization (RBRO).

& Wicklein, ). The analysis stage of the engineering design process is when mathematical models and scientific principles are employed to help the designer predict design results.

The. optimization. stage of the engineering design process is a systematic process using design constraints and criteria to allow the designer to locate the.

A rigorous mathematical approach to identifying a set of design alternatives and selecting the best candidate from within that set, engineering optimization was developed as a means of helping engineers to design systems that are both more efficient and less expensive and to develop new ways of improving the performance of existing systems/5(2).

Further, an optimization method for fleet dispatch and CBM under acceptable risk is proposed based on an improved genetic algorithm.

Finally, a fleet of 10 aircrafts is studied to verify the proposed method. The results shows that it could realize optimization and control of the aircraft fleet oriented to mission by: 3. From this perspective, Uncertainty-Based Multidisciplinary Design Optimization (UMDO) is introduced into academia.

UMDO is a new trend of MDO [2], [20]. It can greatly improve design by benefiting from the synergistic effect of coupling disciplinary collaboration optimization, and meanwhile enhance reliability and by: Book chapters on Optimization Methods for Engineering Design.

Exposure assessment — measurement or estimation of the intensity, frequency, and duration of human exposures to agents. Risk characterization — estimation of the incidence of health effects under the various conditions of human exposure. Once risks are characterized in step 4, the process of risk management begins (Figure 2).

Next, we introduce dynamic measures of risk, and formulate multistage optimization problems involving these measures. Conditions similar to dynamic programming equations are developed. The theoretical considerations are illustrated with many examples of mean-risk models applied in Cited by: Structural Optimization Under Conditions of Uncertainty, with Reference to Serviceability and Ultimate Limit States.

Probability concepts and methods are rapidly gaining ground in the search for more rational approaches to structural optimization.

Under conditions of uncertainty, the risk of unfavorable structural performance provides a consistent measure of design reliability, and thus furnishes a systematic means for comparing design.

The chapter considers the methods for solving general design optimization problems using Monte Carlo simulation of various types. Problems addressing life‐cycle cost and risk optimization can be classified broadly into two somewhat overlapping types: optimal design under stochastic loading, and optimal design considering inspection and.responsibility for all elements of design (engineering), construction and procurement.
