摘要： A computer system (100) comprising a processor device (102) implementing a trained artificial neural network (ANN) for determining a target number of locators and a target distance between adjacent locators placed on a part to fix the part on a fixture, the computer system (100) being configured to:
- collect a part (201) associated with part parameters (PP1, PP2, PP3);
- collect a first set (202) of input dublets (ID1, ID2), each input dublet (ID1, ID2) comprising a first value (ID1) and a second value (ID2), the first value (ID1) being a number of locators and the second value (ID2) being a distance between adjacent locators;
- for each input dublet of the first set, collect as input (203) to the trained artificial neural network the part parameters and said input dublet of the first set;
- for each input dublet of the first set, provide (204) an output dublet (OD1, OD2) predicted by the trained artificial neural network (ANN), the output dublet (OD1, OD2) comprising a first output value (OD1) and a second output value (OD2), the first output value (OD1) being a part deviation defined as a change of a part dimension from a nominal part dimension, and the second output value (OD2) being a part deflection defined as a change of a part form from a nominal part form, so that a second set of output dublets (OD1, OD2) is collected, each output dublet (OD1, OD2) of the second set resulting from an input dublet (ID1, ID2) of the first set;
- select (205) a selected output dublet (OD1, OD2) among the output dublets (OD1, OD2) of the second set, the selection (205) being based on an optimisation criteria, said selected output dublet (OD1, OD2) resulting from a determined input dublet (ID1, ID2) of the first set;
- determine (206) the target number of locators as the number of locators (ID1)of the determined input dublet (ID1, ID2), and determine (206bis) the target distance between adjacent locators as the distance between adjacent locators (ID2) of the determined input dublet (ID1, ID2).
