Numerical Shape Optimization via Dynamic Programming

چکیده

In this paper we describe a novel framework for finding numerical solutions to a wide range of shape optimization problems. It is based on classical dynamic programming approach augmented with discretization of the space of trajectories and controls. This allows for straightforward algorithmic implementation. This method has been used to solve a well known problem called the ”dividing tube problem”, a state problem related to fluid mechanics, that requires simultaneous topology and shape optimization in case of elastic contact problems and involves solving the Navier-Stokes equations for viscous incompressible fluids.

A New Optimization via Invasive Weeds Algorithm for Dynamic Facility Layout Problem

The dynamic facility layout problem (DFLP) is the problem of finding positions of departments onthe plant floor for multiple periods (material flows between departments change during the planning horizon)such that departments do not overlap, and the sum of the material handling and rearrangement costs isminimized. In this paper a new optimization algorithm inspired from colonizing weeds, Invasi...

Shape-topology optimization of stokes flow via variational level set method

In this paper, the conventional level set method is extended as an efficient approach for shape optimization. The motion of the dynamic interface is governed by Stokes equations. Although this method is not specifically designed for topology optimization, it can handle topology changes easily. Furthermore, a relatively smooth evolution can be maintained without re-initialization. The cost of th...

Shape Optimization of an Arterial Bypass in Cardiovascular Systems

A high performance numerical technique in the study of aorto-coronaric bypass anastomoses configurations using steady Stokes equations is presented. The problem is first expressed as an optimal control problem. Then, by using an embedding method, the class of admissible shapes is replaced by a class of positive Borel measures. The optimization problem in measure space is then approximated by ...

Energy cost minimization in an electric vehicle solar charging station via dynamic programming

Environmental crisis and shortage of fossil fuels make Electric Vehicles (EVs) alternatives for conventional vehicles. With growing numbers of EVs, the coordinated charging is necessary to prevent problems such as large peaks and power losses for grid and to minimize charging costs of EVs for EV owners. Therefore, this paper proposes an optimal charging schedule based on Dynamic Programming (DP...
