Function-Based Conceptual Design Expert (CDE) Systems: Development Trend and Gaps Identification

noThis paper presents an overview of existing function-based conceptual design expert (CDE) systems with a view to identifying their scope in the contexts of functional modeling knowledge representation and conceptual design process. A number of heterogeneous function-based CDE systems are identified and listed. A key comprehensive benchmarking framework is developed in this paper that helps in identifying the trend, gaps and scope of current function-based CDE systems. Accordingly, the gaps in the aforementioned contexts are discussed which are to date have not been summarized and highlighted for a well-balanced system development for a product conceptual design
