Evolution-Inspired Approaches for Engineering Emergent Robustness in an Uncertain Dynamic World
نویسنده
چکیده
Engineering involves the design and assemblage of elements that work in specific ways to achieve a predictable purpose and function. In systems design, engineering takes a conceptual “top-down” approach to problem solving that aims to decompose a complicated problem into separable and more manageable sub-problems. While this strategy has been successful in designing systems that deftly operate under predetermined conditions, these same systems are often notoriously fragile when conditions change unexpectedly.

A Robust Scenario Based Approach in an Uncertain Condition Applied to Location-Allocation Distribution Centers Problem
The paper discusses the location-allocation model for logistic networks and distribution centers through considering uncertain parameters. In real-world cases, demands and transshipment costs change over the period of the time. This may lead to large cost deviation in total cost. Scenario based robust optimization approaches are proposed where occurrence probability of each scenario is not know...
متن کاملRobust optimization of a mathematical model to design a dynamic cell formation problem considering labor utilization
Cell formation (CF) problem is one of the most important decision problems in designing a cellular manufacturing system includes grouping machines into machine cells and parts into part families. Several factors should be considered in a cell formation problem. In this work, robust optimization of a mathematical model of a dynamic cell formation problem integrating CF, production planning and w...
متن کاملPerformance Analysis of Dynamic and Static Facility Layouts in a Stochastic Environment
In this paper, to cope with the stochastic dynamic (or multi-period) problem, two new quadratic assignment-based mathematical models corresponding to the dynamic and static approaches are developed. The product demands are presumed to be dependent uncertain variables with normal distribution having known expectation, variance, and covariance that change from one period to the next one, randomly...
متن کاملOptimization in Uncertain and Complex Dynamic Environments with Evolutionary Methods
In the real world, many of the optimization issues are dynamic, uncertain, and complex in which the objective function or constraints can be changed over time. Consequently, the optimum of these issues is changed nonlinearly. Therefore, the optimization algorithms not only should search the global optimum value in the space but also should follow the path of optimal change in dynamic environmen...
متن کاملADAPTIVE BACKSTEPPING CONTROL OF UNCERTAIN FRACTIONAL ORDER SYSTEMS BY FUZZY APPROXIMATION APPROACH
In this paper, a novel problem of observer-based adaptive fuzzy fractional control for fractional order dynamic systems with commensurate orders is investigated; the control scheme is constructed by using the backstepping and adaptive technique. Dynamic surface control method is used to avoid the problem of “explosion of complexity” which is caused by backstepping design process. Fuzzy logic sy...
