Design of differentiated warranty coverage that considers usage rate and service option of consumers under 2D warranty policy

Warranty service providers usually provide homogeneous warranty to improve consumer satisfaction and market share. Considering the difference of consumers, some scholars have carried out studies on maintenance strategies, pricing, payment method, claim behaviour cost analysis in recent years. However, few focused differentiated coverage that considers usage rate option consumers. On basis previous classification criteria rate, this paper divides consumers into heavy, medium light groups with clear boundaries. To avoid discrimination service, study 2D disjoint sub-regions adopts different modes each sub-region. By formulating calculating model under constraints, we can obtain maximum $ r $. Therefore, scope for three be proposed, whilst choose most suitable according their rate. Evidently, proposed strategy flexible meet requirements constraints enable enterprises occupy a favourable position competition.
