20 Having a significant impact on the design of many products and industrial systems, such as the subdivi21 sion of a ship, the layout of facilities in a plant or further still the assembly of parts of a mechanism, layout 22 design optimization is at the heart of scientific issues. The design of an optimal layout solution is a critical 23 and complex task due to the increasing demands of design...

The objective of this work is to develop a specialized integrated design tool for MEMS compliant mechanisms from topology to shape optimization. We use the topology optimization technology to obtain an optimal mechanism layout achieving the best overall system performance. This design process is followed by shape optimization to improve stress-based local performance around hinges of the mechan...

Deformation of theworkpiece may cause dimensional problems in machining. Supports and locators are used in order to reduce the error caused by elastic deformation of the workpiece. The optimization of support, locator and clamp locations is a critical problem to minimize the geometric error in workpiece machining. In this paper, the application of genetic algorithms (GAs) to the fixture layout ...

nowadays, different methods are used to solve optimization problems which ,one of the newest is bco method that are inspired by the nature and derived from the social life of bees of these methods can be noted that bco is derived from the social life of bees. we use in this paper fuzzy logic for bee‟s decision stage. at the end, we solve two different problem that have already been solved by es...

In textile industry, marker planning is one of the main operations in the cutting fabric stage. Marker packing is usually used to maximize cloth exploitation and minimize its waste. In this research, a method is used based on new found meta-heuristic imperialist competitive algorithm (ICA) and Bottom-Left-Fill Algorithm (BLF) to achieve optimal marker packing. Function of the proposed method wa...

A node-based design variable implementation for continuum structural topology optimization in a finite element framework is presented and its properties are explored in the context of solving a number of different design examples. Since the implementation ensures Ccontinuity of design variables, it is immune to elementwise checkerboarding instabilities that are a concern with element-based desi...

Variable Data Printing (VDP) refers to the process of generating and printing dynamic or personalized contents. A core technology required by highly customized VDP applications is the automatic document layout design engine, whose task is to adjust the original design or generate a new layout to present variable contents. This paper presents a novel document layout design engine, called Active ...

Based on the Systematic Layout Planning theory and the analysis of transfer stations’ technological processes, a layout optimization model for solid waste transfer and disposal stations was made. The operating units’ layout of the solid waste transfer and disposal stations was simulated and optimized using the genetic algorithm, which could achieve reasonable technological processes, the smalle...

The two-dimensional layout problem is known to be NP-complete, and the current research work is basically in the heuristic way. In this paper, we mainly discuss the methods for solving layout problem about the arti®cial satellite module by virtue of graph theory and group theory. Also, an algorithm of global optimization is presented ®rst time. The method given here can be extended to solve oth...

In this study an efficient meta-heuristic is proposed for layout optimization of truss structures by combining cellular automata (CA) and firefly algorithm (FA). In the proposed meta-heuristic, called here as cellular automata firefly algorithm (CAFA), a new equation is presented for position updating of fireflies based on the concept of CA. Two benchmark examples of truss structures are presen...
