Abstract:
An apparatus for designing an information system, said apparatus comprising:an input module for receiving descriptive input of a target information system, said descriptive input including descriptions of business processes and business functions;a construction module for receiving said descriptive input from said input module, said construction module (i) deriving quantitative input from said descriptive input, said quantitative input including number and kind of hardware and software components for said target information system, (ii) designing an initial multi-layer mathematical model of said target information system based on said quantitative input, said layers of said mathematical model comprising a business layer, an application layer, and a system/network layer, said business layer generating data for said application layer and said system/network layer, said application layer responsive to said generated data presenting service requests to said system/network layer, said system/network layer responsive to said generated data and said service requests generating processing and servicing data, said processing and servicing data of said system/network layer factored into said business layer and said application layer, and (iii) designing at least one additional multi-layer mathematical model from said quantitative input, said multi-layer mathematical models being designed prior to implementation of said target information system;a performance metrics module for evaluating said designed initial model and said at least one additional model, said performance metrics module calculating performance metrics for said designed initial model and said at least one additional model at each layer; andan output module for outputting said designed initial model, said at least one additional model, and said performance metrics.
