有点难搞，只做了个并集的，效率不错，不知道是否通用，还待测试~~~

@echo off&setlocal enabledelayedexpansion
set A={1,[3,6],10,[20,30],[32,60],[200,3000],5000,[6000,8000],9000,9500}
set B={2,5,31,[300,500],[8000,9000],9500}


::拆分A 和 B的数据集
set/a n=0,m=0

set Av=!a:[=]!
set Av=!Av:]="!

for %%a in (%Av:~1,-1%) do (
	set a!n!=%%~a
	set/a n+=1
)

set Bv=!B:[=]!
set Bv=!Bv:]="!


for %%a in (%Bv:~1,-1%) do (
	set B!m!=%%~a
	set/a m+=1
)


::设置上限
set /a A!n!=2000000000
set /a B!m!=2000000000


::根据a和b总项数来确定循环次，根据并集规则，进行判断重组
set/a mn=m+n,n=0,m=0
for /l %%a in (0,1,!mn!) do (
	for /f "tokens=1,2" %%m in ("!m! !n!") do (
		for /f "delims=," %%x in ("!A%%n!") do (
		for /f "delims=," %%o in ("!B%%m!") do (

		if %%x gtr %%o (set var=!B%%m!&set cur=m) else (set var=!A%%n!&set cur=n)

		for /f "tokens=1,2 delims=," %%1 in ("!var!,!var!") do (
			if !next! lss %%1 (
				if !fa! equ !end! (set aUb=!aUb!,!fa!) else (set aUb=!aUb!,[!fa!,!end!])
				set fa=%%1
			)

			set ben=%%1
			if !end! lss %%2 set end=%%2
		)))

		set /a !cur!=!cur!+1,next=end+1
	)
)
echo;并集计算：
echo;AUB={!aUb:~2!}

交集处理，在并集处理的模版改为交集的处理而已，没有多少变化。

@echo off&setlocal enabledelayedexpansion
set A={1,[3,6],10,[20,30],[32,60],[200,3000],5000,[6000,8002],9000,9500}
set B={2,5,31,[45,49],55,[300,500],[8000,9000],9500}
