Table 5

Distance from plants to potential RDCs by different transport modes (km).

Plants	RDCs and warehouses
	D1	D2	D3	D4	D5	W6	W7
P1	380/440/320	320/460/280	340/470/290	340/480/300	310/460/260	310/440/290	320/460/300
P2	440/540/400	460/550/410	500/640/440	530/670/500	430/580/400	380/550/350	600/740/560
P3	280/450/250	550/690/500	480/660/400	480/640/450	350/500/300	610/760/570	460/420/420

Note: the three values of each cell of distance in Table 5 represent the three different distance values by road, train, and air transportation, respectively (e.g., 380/440/320 means that the distance from P1 to D1 by road, train, and air transportation transport modes is 380, 440, and 320 km, resp.).
