Towards a better psychological satisfaction: developing a mixed multi-criteria evaluation system to urban ‘Not in my back yard’ facilities siting

Table 2 Comparison of the basic conditions of the three waste incineration plants siting schemes

Modules	Evaluation criteria	Scheme 1	Scheme 2	Scheme 3
Spatial planning	Public impact	4	3	2
	Land size (sqm)	53300	57600	60400
	Industrial impact	3	3	2
	Landscape impact	1	2	1
Environmental protection	Atmospheric Environmental Impact (ppm)	0.4	0.6	1
Environmental protection	Noise (decibels)	8	8	5
Construction-operations	Land cost (10,000 CNY)	1020	920	870
	Construction investment (10,000 CNY)	33500	35300	35500
	Infrastructure investment (m)	1540	2520	3680
	Transportation cost (m)	9800	11500	14400
	Operation cost (10,000 CNY per year)	1560	1650	1680
Sociopsychology	Public perception	4	4	2

Qualitative criterion data are determined by the Delphi method and quantitative criterion data are provided by relevant departments
Then, we conducted data preprocessing. Evaluation criteria were divided into two categories, namely qualitative criteria and quantitative criteria, which could be represented by ‘O’ and ‘C’, where:
O = {public impact, industrial impact, landscape impact, public perception}, and is the set of all qualitative criteria
C = {Scale of site, atmospheric impact, noise, land cost, construction investment, infrastructure support, transportation cost, operation cost}, and is the set of all quantitative criteria
