Abstract: With regard to shortcomings in single conflict resolution, conflict object was categorized as parameter layer, characteristics layer, structure layer and schematic layer. Conflict resolution in schematic layer was studied in particular. Conflict problem was described in mathematic form using the concept of multi-objective vector space and the origin of conflict was explained mathematically at firstly. Then, resolution arithmetic of scheme-layer conflict was put forward using optimized arithmetic of Multi-Objective Decision-Making. Concrete implementation steps for the optimized arithmetic was described in detail. As the result, designers could find the only optimized solution among many feasible schemes. Finally, an example of gear retarder was used to show the validity of this arithmetic.

Key words: collaborative design, conflict resolution, conflict layer, multi-objective decision-making
