Coordinative Urban-Rural Solid Waste Management: A Fractional Dual-Objective Programming Model for the Regional Munifcipality of Xiamen

Table 8

Comparison of optimal ratio model and minimum cost model.

	Optimal ratio model	Minimum cost model
System cost (10^6 RMB)	8,372.53	7,923.02
Waste diversion (10^3 ton)	42,436.18	40,051.49
Waste diversion rate (%)	97.1	91.6
Waste diversion/cost; (10^3 ton/10^6 RMB)	5.069	5.055

When the total system cost is 10⁶ RMB, 10³ tons of waste in total will be diverted to incinerators and the composting plant.
