Abstract
PurposeThe purpose of this paper is to present a multi‐expert system that can provide designers with suggestions for improvement. The multi‐expert system can analyse a design and provide designers with ideas for changes to designs at an early stage in order to improve assembly later in the manufacturing process.Design/methodology/approachThe 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 sub‐system to collate the information from the assembly experts and to provide costs and advice.FindingsThe paper finds that the approach and the systems can reduce manufacturing costs and lead times.Research limitations/implicationsA 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 implicationsThe system can estimate assembly time and cost for manual or automatic assembly and select a suitable assembly technique.Originality/valueThe 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 is captured and embedded within the individual expert that represented the process. This approach enabled greater flexibility and made the sub‐systems easier to modify, upgrade, extend and reuse.
Highlights
Some existing Systems have provided assistance to designers during early design stages in order to reduce product development time
The whole system consists of four expert systems: Computer Aided Design (CAD) Expert, Automated Assembly Expert, Manual Assembly Expert and Design Analysis Expert
The new system described here was created to overcome this by modelling assembly, product and process design using a natural approach for capturing intelligence
Summary
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. 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. 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
