4. Discussion and conclusion
In this proposed framework the application of the decision and intelligent support system in metal casting and it identifies the gaps from the extent literature review which provides in turn an opportunity in future to study more about metal/die to cast.From the literature review it is found that most of the study are concentrated on GA and ANN very few have conducted by the authorsZhang et al., 2007b, Sun et al., 2011, Jin & Kang, 2012, Wen et al., 2012, Kuo et al., 2013 concentrated towards DSS. On the other hand, few authors have concentrated on KBS, ES, fuzzy and hybrid. In addition, it is found that largest journal of materials processing technology and materials science and engineering: A has the highest collection of journal articles and in this the collected articles are based on theonly casting of metals through metallic alloys. In future, more research can be conducted based on KBS, ES, Hybrid system by considering metal casting in different journals and adapting a large number of metallic alloys.
