i thought i wrote this before but it didnt seem to register. my post disappeared :(
with regard to the lost pound the real reason is as follows:
it was a bank holiday weekend and everybody was drunk, including the bell boy and concierge, so knowbody knows or cares where the extra pound has gone.
cheers for clearing up the whole float thing up as well everyone. never really use that format. was also being a complete muppet when it came to earliest and latest start. its ok. the mist has cleared. i have seen the error of my ways and the stupidity of my logic. one rule learned. look before you leap. or read over before you post. :)

The description is right Stephen, well done for cutting through the c**p and explaining it simply.
Anoon, thats why you shouldnt give the client any more than a level 1 programme and updated it with a zigzig dropline! Clients cant understand what we do, and dont want to. Their job is to make money for their company. The only reason they ask for more detail is because theyve been told they should, but theyll never understand it.
Stephen, each of the men pays £9, thats 3x9 = £27, less the £2 the bellboy pockets is £25 to the hotel. The question is fallacial.

You can get negative float in this case if there is a No Later Than constraint after activity C. The early dates of C will not be affected as they come before the constraint -- however, the late dates will be computed back from the constraint, which says that no matter when the logic and durations indicate the activity should start/finish, they are overridden by the calendar-based constraint. Even though the logic indicates that activity c has an ES of day 15, the constraint says it can start no later than day 6.
yes & no, IMHO, it happens because of the events going out-of-sequence; and the calculations are based on mathematical principles, which will give you either positive or negative results, which is logical.
While in reality, (for example) how can you explain it to a client who doesnt even want to look at your plan?
Officially paid was only 25 (that is with receipt including VAT); and I have returned 3 (one each) to them. Well ...I dont know the rest....

can someone please explain to me how a late start can be earlier than an early start? this makes no sense to me. in my eyes, as soon as the late start comes back to the early start there is no float. as soon as it passes the early start it becomes the early start?!? yes? no?
As for the extra pound, i think you both hit the nail on the head. although when it was explained to me the phrase negitive equity can not be combined or calculated with a positive credit. was used. this didnt actually help me in any way with the explaination. I needed it in laymans terms which was as follows:
They are both right, however the two parties situations cannot be talked about from a singular perspective. it is then the confusion arises.
was going to try and explain both situations and then totally confused myself again. as i said, im a messenger, an actuary told it to me. everytime i think about it, it pickles my head again. i keep sorta grasping it, then loosing it completly again when i think, no, hang on, they all paid £9 and the bell boy kept £2... then im back to square 1. i understand it. i know its right. i just dont agree with it.
Activity c is sometimes termed to be "supercritical".
More important, if all four are parallel, and are the only items that are parallel with one another, then activity c has DRAG of 10 (provided it has a duration of 10 or more).
It is usually better practice to compute float as late finish minus early finish, rather than late start minus early start (and, yes, you can get different answers depending on which way you compute).
The three guests paid &27. The hotel received &25. The bell boy recieved &2.
is it just me or is this complete nonsense? i may be showing inexperience here but surely item activity c is wrong? how can a late start come before an early start? would they not just turn round and become early start 6 and late start 15? this is nonsense...
heres a better one.
3 friends go into a hotel and book a room. the room cost £30 so they each pay £10 and walk off to the lifts. the concierge then remembers that there is an offer on and a room only costs £25 so he calls the bell boy and gives him £5 to take up to the guests. on the way up to the room in the lift the bell boy cant work out how to split the £5 between 3 and so puts £2 in his own pocket and gives each of the 3 guests £1 back.

no Professor, the money involved is only 28 (budget), 2 is contingency (i worked as a bell boy before)

Activity d has the most float = 8.
Activity c has the least float = -9.
Activity c is sometimes termed to be "supercritical".
More important, if all four are parallel, and are the only items that are parallel with one another, then activity c has DRAG of 10 (provided it has a duration of 10 or more).
It is usually better practice to compute float as late finish minus early finish, rather than late start minus early start (and, yes, you can get different answers depending on which way you compute).
The three guests paid &27. The hotel received &25. The bell boy recieved &2.
&25 + &2 = $27 received, = what was paid out.

This means each guest paid £9..
3 x £9 = £27 plus the £2 the bell boy kept is £29
Where did the other pound go?
