Some issues on the weights analysis in multi-objective decision making and multiple learning machines system

Some important issues on the determination of weights in multi-objective decision making (MODM) and multiple learning machines system (MLMS) are discussed: it is presented that determining weights is an important evaluation process; some drawbacks of several current methods of determining weights with the help of optimization are analyzed. Meanwhile, it is pointed out that it's not overall and unreliable to regard the determination of weights as a single optimization problem based on limited data; Review and new research are carried out for general variable weights and its special case-the variable weights integration of modular neural networks; the inconsistency of weights is elementarily discussed and the reasons on this inconsistency are analyzed.
