Abstract

Provided is a data processing system and a method for generating states of a model defined within a modelling application. The modelling application generates a state of the model based on the values of a number of input variables. A modification means alters the values of the input variables, and provides those altered values to the modelling application to cause a new state of the model to be generated. The modification means repeats the production of altered values such that a set of states of the model is generated. A display means produces a graphical representation of each state of the model in the set and displays the graphical representations on a display device. The system includes control means, responsive to signals received from an input device, to enable a user to select graphical representations from those displayed and to place the selected graphical representations in a predetermined area of the display device; and weighting means for automatically assigning a weighting to each graphical representation within the predetermined area, this weighting being dependant on the position of the graphical representation within the predetermined area. The modification means is responsive to the weighting of each state of the model to produce altered input variables for a subsequent set of states of the model. The generation of the set of states of the model and display of their graphical representations is then repeated.

Dependent claims

A data processing system for generating states of a model, the model being defined within a modeling application and having a plurality of input variables associated therewith, the modeling application being arranged to generate a state of the model based on values of the input variables, the system comprising:

modification means for altering the values of the input variables, and for providing the altered values to the modeling application to cause a new state of the model to be generated,
said modification means being arranged to repeat a selected number of times a production of altered values thereby causing a set of states of the model to be generated by the modeling application;
display means for producing a graphical representation of each of the states of the model in the set and for displaying the graphical representations on a display device connectable to the data processing system, said display means being arranged to display a plurality of the graphical representations;
input control means, responsive to signals received from an input device connectable to the data processing system, to enable a user to select at least one graphical representation from the displayed graphical representations and to move the selected graphical representations into or from a predetermined area of the display device;
graphical representation re-arranging means, responsive to the user moving the at least one graphical representation from a first location on the display device to a second location within the predetennined area on the display device, for re-arranging the displayed graphical representations on the display device to allow insertion and display of the moved graphical representation in the second location;
said modification means being responsive to the values of the input variables of each of the states of the model represented by one of the graphical representations in the predetermined area of the display device, to produce altered input variables for a subsequent set of states of the model;
the data processing system being arranged to repeat generation of the set of states of the model, and to display graphical representations of those states.

A method of operating a data processing system to generate states of a model, comprising the steps of:

(a) storing the model in a modeling application, the model having a plurality of input variables associated therewith;
(b) altering the values of the input variables and providing the altered values to the modeling application to cause a new state of the model to be generated, the state of the model being based on the values of the input variables, this step being repeated a selected number of times to cause a set of states of the model to be generated;
(c) producing a graphical representation for each state of the model in the set;
(d) displaying the graphical representations on a display device;
(e) employing input control means to enable a user to select graphical representations from the displayed graphical representations and to move the selected graphical representations into or from a predetermined area of the display device;
(f) employing graphical representation re-arranging means, responsive to the user moving one of the graphical representations from a first location on the display device to a second location within the predetermined area of the display device, to re-arrange the graphical representations on the display device to allow insertion and display of the moved graphical representation in the second location;
(g) determining new initial values for the input variables of the modeling application, based on the values of the input variables of each state of the model represented by a displayed graphical representation in the predetermined area;
(h) employing modification means to alter the new initial values within predetermined limits;
(i) inserting such altered values into the modeling application to cause a new state of the model to be generated;
(j) repeating said steps (g) to (i) a selected number of times to generate a new set of states of the model;
(k) producing and displaying graphical representations for each state of the model in the new set;
and
(l) repeating said steps (e) to (k) at a user's request.
