3.2 the process mode that traversal step 3.1 obtains tabulation compares the business objective of process mode in the tabulation and the business objective of user's input; If identical, the coupling score value of this process mode is made as 1.0, and carries out next step, if different, reads next process mode in the tabulation, in traversal of lists till all process mode;
3.3 obtaining the coupling score value is the application scenarios of 1.0 process mode; According to each scene entry of application scenarios and the valuation functions in the process mode storehouse; Application scenarios assessed draw the application scenarios point value of evaluation, its calculating formula is: application scenarios point value of evaluation=∑ (positive factor scene entry weight * positive factor scene entry point value of evaluation)-negative factor influence coefficient * (negative factor scene entry weight * negative factor scene entry point value of evaluation);
3.4 judge that whether the application scenarios point value of evaluation is greater than application scenarios assessment threshold value; Be, carry out next step, not, do not read next process mode in the tabulation, in traversal of lists till all process mode;
3.5 coupling score value, application scenarios point value of evaluation and business objective influence coefficient according to process mode; Calculate the total score value of coupling of this process mode, its computing formula is: mate total score value=coupling score value * business objective influence coefficient+application scenarios point value of evaluation;
3.6 judge that whether the total score value of coupling is greater than the coupling threshold value; Be, this process mode is listed in the candidate's process mode tabulation, not, read next process mode in the tabulation, in traversal of lists till all process mode;
3.7 according to all the process mode descending sorts in the big young pathbreaker candidate process mode tabulation of the total score value of coupling;
3.8 from the tabulation of candidate's process mode, read the highest process mode of the total score value of coupling, and generate the flow definition of this process mode.
9. according to claim 5 or 6 said workflow dynamic programming methods, it is characterized in that step (4) is concrete to be realized as follows based on process mode:
4.1 the process mode that is complementary that step (3) is found out replaces with sub-process, father's flow process of this sub-process is this process mode place flow process;
4.2 input and output parameter maps with the business objective of the variable of father's flow process and this process mode; And the mapping of the input and output parameter of the business objective of this process mode and sub-process input, replace with the variable of father's flow process and the input and output parameter maps of its sub-process;
4.3 accomplish the adaptive of flow definition.
10. according to claim 5 or 6 said workflow dynamic programming methods, it is characterized in that based on process mode, in the step (5), in the described flow definition if comprise goal activities, the then same step of implementation (2)~(5); Otherwise, carry out said flow definition until complete.
