Thanks for your help Oligolas. my respons below
rule 1°) each person should have one type1/week AND one type2/week AND one type3/week. But only one type(1 or 2 or 3) per date (and per person).
A)Can you have a type3 today and a type1 tomorrow? yes.
rule 2°) for each day, and each type (1,2,3), it should have at leat 2 persons
B)Are you trying to get the maximum or the minimum possible occupation of persons per day and week? I try to get the minimum wich is 4
rule 3°) each person should have one type4 per month. it should be on saturday
C)with 14 subjects and 4 weeks a month you would get an occupation of up to 4 persons a saturday, if I balance the groups, is that what you intend to do? no matter the number of subject on saturday. I just want that each person work at least one saturday per month
rule 4°) each person should have one type5 in the week when he has a type4
D)Otherwise no day off!? how many type5 per month? firstly, we Don't want to deal with the holidays (except the day off when you work on saturday)
E)And what are the rules for type0? what does type0 mean? How many per week/month? type0 (default value) means no constraint, ordinary day. for exmple, monday=type / tuesday=type2 / wednesday=type3, then Thursday and friday are type0
F)what's the difference between Type0 and Type5? type5 is a day off (your are at home) but type0 you work without constraint. type0 = you start/finish as standard (from 9AM to 5PM). type1 = you start at 8:00 AM / type2 = you finish at 6:00 PM / type3 = you finish at 7:30 PM
G)Is there the intention to maximize or minimize some Types per week? get the less or the maximum occupation? if it is possible, the intention is to minimize type per Week. get the less occupation. but respect the minimun of 2 persons for each type and each day
many Thanks
