Multiagent business objects and Intelligent Multimedia applications for Management Science and IT are defined. Amongst the areas are agent computing, modern portfolios, heterogeneous computing, business objects, intelligent databases, intelligent objects, and decision science. A new view to MIS with agent computing and intelligent multimedia is presented. Interaction amongst heterogeneous computing resources are via objects, multiagent AI and agent intelligent languages. New applications to business with intelligent object languages are presented in brief. Intelligent multimedia and the new Morph Gentzen logic from (Nourani 1997a) are applied as a preliminary basis for to forecasting. We present a brief overview to new KR techniques with G-diagrams and applications to define computable models and relevant world reasoning. G-diagrams are applied to KR to define localized keying to models and as a minimal efficient computable way for knowledge management.
