Abstract: A computer system for analyzing and automatically modifying existing process system models that includes (i) an Initial Data stage that prompts the user to enter qualitative and quantitative objectives in designing or re-designing a Process System, (ii) a Component Model stage that displays an image of the sequence of components produced or added during the process and that allows the user to edit or complete the Component Model display that includes components, which are produced during the process, operations that produce them, and functions, each consisting of an element or tool that causes an action and an element or tool that receives the action, (iii) a Process (Functional) Analysis stage that includes functional and interaction relationships of the functions and operations designating each function as harmful or useful, and ranking each useful function according to the value of its contribution to the respective operation, and performing a value link analysis of each function including the level of the

Abstract: A software system includes an engineering analysis system (EAS) for analyzing an engineering object system and for recommending elimination of object system components. The EAS includes a functional model unit responsive to user entry for generating images of a functional model of the object system including its components, elements and products and representations of the interactions between the generated components, elements, and products. The functional model can be represented as a number of component/element boxes and harmful and useful interaction lines therebetween, or the functional model components, elements and products can be represented in matrix form with interactions identified in the intersections of the matrix. The EAS includes an advanced link analysis unit for prompting user entry, storing and displaying of (i) a parameter of at least one of said interactions, (ii) the actual and desired quantitative or qualitative values of said parameter, (iii) a time and space dependency of the parameter.
