An expert system for automatic design‐for‐assembly

Abstract

Purpose-A Multi Expert System is presented that can analyse a design and provide designers with suggestions for improvement and changes to designs at an early stage in order to improve assembly later in the manufacturing process. The Multi Expert System can analyse a design and provide designers with suggestions for improvement and changes to designs at an early stage in order to improve assembly later in the manufacturing process. Design/methodology/approach-The whole system consists of four expert systems: Computer Aided Design (CAD) Expert, Automated Assembly Expert, Manual Assembly Expert and Design Analysis Expert. The Design Analysis Expert includes a subsystem to collate the information from the Assembly Experts and to provide costs and advice Findings-The approach and the systems can reduce manufacturing costs and lead times. Research limitations/implications-A knowledge-based reckoning approach to design-for-assembly automation is used. The approach and systems can reduce manufacturing-costs and lead-times. The system can estimate assembly-time and cost for manual or automatic assembly and select suitable assembly techniques. Practical implications-The system can estimate assembly time and cost for manual or automatic assembly and select a suitable assembly technique. Originality/value-The new system models assembly, product and process design using a natural approach for capturing intelligence. The new approach categorised automated assembly and manual assembly into separate individual experts. Intelligence and knowledge from each was captured and embedded within the individual expert that represented the process. This approach enabled greater flexibility and made the subsystems easier to modify, upgrade, extend and reuse.

A Welding Capability Assessment Method (WCAM) to support multidisciplinary design of aircraft structures

“…Much of the recent work focuses on providing computer support by using expert systems and KnowledgeBased Engineering (KBE) [14,[24][25][26][27].…”

Improving automatic robotic welding in shipbuilding through the introduction of a corner-finding algorithm to help recognise shipbuilding parts

“…The many different methods of implementing AI each have their own strengths and weaknesses [9][10][11][12][13][14]. Some effort has been made in combining different methods to produce hybrid techniques with more strengths and fewer weaknesses.…”

Sensor-based ambient intelligence for optimal energy efficiency

“…The research described in this paper combined ambient intelligence (AmI) (Sanders et al, 2007;Sanders, 2009e) and knowledge management (KM) technologies (Sanders and Gegov, 2006;Snidaro and Foresti, 2007) with AI (Sanders, 2009a, b;Sanders et al, , 2012aSanders and Gegov, 2013) and expert systems (Sanders et al, 2009(Sanders et al, , 2011a. That was to addresses two of the most critical problems in energy management in industrial production technologies: how to efficiently and promptly acquire and provide information online for optimising energy consumption; and how to effectively use such knowledge to support decision making.…”
