In this paper we propose an indicator to measure the capacity of a slicing tree to generate geometrically acceptable solutions for layout problems based on the slicing tree structure. This indicator can predict if, by making the appropriate cuts, the tree structure is able to generate layouts that satisfy the geometrical restrictions imposed on the items to be arranged. It also permits the determination of the most suitable aspect ratio of the layout zone in order to minimize non-compliance with the geometric restrictions. The method of calculating the indicator and its application to the facility layout problem are described, and the results obtained in the experiments carried out are also given. 相似文献

AbstractThis work presents an original combination of the Systematic Layout Planning (SLP) methodology with Quality Function Deployment (QFD) for layout design of services. This methodology considers two stages. The first of these stages is Quality Function Deployment using the Modified Quality Matrix, and the second, the application of the various phases of the SLP method, using the data obtained during the first stage, in order to find a layout design which contains the client’s perception. The developed methodology was applied to redesign the layout plan for one academic department of the Universidad de Santiago de Chile. This application enabled the generation of alternative distributions, which were compared to the current layout, and the assessment was conducted by a team from the Department itself, using the Analytic Hierarchy Process (AHP). 相似文献

In previous optimization methods for multi-module satellite equipment (component) layout optimization problem, each component was limited to certain module or supporting surface and could only search its position there. Components could not migrate from one module or supporting surface to another. In this case, the layout design of components within satellite module was seriously hindered from further improvement. In this study a component assignment and layout integration optimization algorithm is presented to deal with this problem, which can assign components to each module of satellite dynamically during optimization procedure. The aim of this paper is to expand the solution space of component layout optimization so as to further improve the component layout design. The proposed component assignment and layout integration optimization algorithm is inspired from the idea of stepwise regression in multiple regression analysis, which allows independent variables to enter or leave regression equation freely. In the proposed algorithm components enter the satellite module one by one in descending order of the product of mass and height. For all supporting surfaces within satellite module, each component will try all of them through layout optimization together with these components have been in the satellite module, and finally select the one with the best fitness as its initial assignment. At the same time, these components have been in the satellite module will be evaluated by their moment of inertia to decide whether they leave the current supporting surfaces and move to another or not. The layout optimization algorithm uses the differential evolution (DE) and random mutation operation to optimize the coordinates and orientations of components, respectively. The performance of the proposed algorithm is finally evaluated on a simplified satellite case. Experimental results show the proposed algorithm outperforms other two algorithms that did not consider component assignment in computational accuracy. 相似文献

This paper describes the characteristics of a new CAD tool that enables the creation of layout libraries of selected analog modules. This Analog Modules Generator (AMG) automatically creates multiple layout versions of two commonly used analog structures: the differential pair and arrays of series-connected or stacked devices, for the subsequent generation of layout libraries. Based on the number of devices and rows defined by the user for the layout implementation, the tool validates all possible implementations, which are later saved in a database. Additionally, an extraction process can be optionally executed over all the layout views saved in the database. The AMG generates several reports with all the characteristics of the implemented layouts, including area and parasitic components, facilitating further statistical processing. We describe the features and capabilities of the proposed AMG tool, and several test cases are presented. Results show that suitable layout implementations can be achieved by layout and circuit designers in a very reduced amount of time. 相似文献
