A Study on the Optimization Method for Panel Layout Problem in Drywall

Abstract

This study is aimed at developing methods to optimize the material yield of drywall panels. In this paper, the authors describe the drywall panel layout optimization method which consists of the following three steps: first, to generate possible alternative patterns of drywall panel layout in a wall; second, for each alternative pattern, to find out the best combination of panel parts to be cut from a panel of standard size; third, to solve the cutting length of panels, the waste volume of panels and the length of panel joints in each layout pattern.The authors applied this method to minimize the cost of drywall using plaster board (1820×910mm). The method generates possible patterns of drywall panel layout in the wall and acquires the best combination of panels to be cut from a standardsize panel, then estimates the cost of drywall works in each pattern.

Integrated, Automated and Robotic Process for Building Upgrading with Prefabricated Modules

“…Normally the process of building renovation with prefabricated modules starts with the existing building´s data acquisition. Progress has been made to implement 3D laser scanning for acquiring the data of spatial environment [12]. The question arises, if this technique is accurate enough for manufacturing and installing parts onto a previously built environment with high enough accuracy.…”
