An Improved PSO Algorithm for Optimized Material Scheduling in Emergency Relief

Table 4

Information on the demand for different materials at different relief points.

	Material requirements (tons)	Inadequate supply of material life hazard level	Degree of material irreplaceability	Tightness factor
	48	3	5	1.0654
	42	3	5	1.0000
	26	5	7	1.1597
	52	5	7	1.4430
	36	7	6	1.5406
	28	7	6	1.4534

annotation: the range of the degree of life-threatening and non-substitutable levels of undersupply is [0–10].
