The present disclosure provides a method and system for optimizing the dispensing of an adhesive from a dispensing device comprising a controllable setting. It consists in obtaining target parameters for a parameter of a structure formed by the adhesive after it is dispensed. Then a value of a local parameter near the dispensing device is obtained, which is a physical parameter of the adhesive in the dispensing device, an environmental condition near the dispensing device or a mechanical parameter of the dispensing device. Then a model of relationships between the local parameter, the parameter of the structure and intrinsic properties of the adhesive is generated. Using this model and the obtained values, a controllable setting for operating the dispensing device is determined to form a structure after dispensing of the adhesive that satisfies the target parameter.
