what is pareto?

i have heard the words "pegasus" and "georoute" but not pareto.

somebody been out shopping?

At a Pareto efficient allocation (on the Pareto frontier), the marginal rate of substitution is the same for all consumers. A formal statement can be derived by considering a system with m consumers and n goods, and a utility function of each consumer as zi = fi(xi) where is the vector of goods, both for all i. The supply constraint is written for . To optimize this problem, the Lagrangian is used:

where λ and Γ are multipliers.

Taking the partial derivative of the Lagrangian with respect to one good, i, and then taking the partial derivative of the Lagrangian with respect to another good, j, gives the following system of equations:

where ƒx is the marginal utility on ƒ' of x (the partial derivative of ƒ with respect to x).

Bet you wish you'd never asked now.
Ask your lino about it tomorrow. I'm sure he will be able to give you a simple explanation.

Also called the 80 / 20 law. 80% of worlds wealth is held by 20% of population. In RM 80% of the work is done by 20% of the workforce......possibly. 22 Jul 2011, 19:25

80% of complaints probably do come from 20% of customers.

22 Jul 2011, 19:28

80% of the office moan about the other 20%

22 Jul 2011, 19:38

I've just read 20% of Postman's posts and 80% were rubbish.

22 Jul 2011, 20:42

80 % of bonuses go to less than 20 % of workforce

I'll call that the Parasite principle

22 Jul 2011, 21:11

80% of Avatars are ok,19.99 are okable 0.1 get...

aye. thats what i thought.

Bloody Hell Jessica expect a call from Rupert Murdoch, he needs someone to confuse them MPs.

It's purely a "should take" measurement not a target that members have to meet.
It was never designed to measure performance.

Sorry fishtank, but what is the difference between
" should take time" and a performance measure.

It's the nueanced distinction we're reduced to making since we agreed to use IWT without getting movement from RM on their unreasonable performance standards first. clashcityrocker wrote:One is a conduct issue, the other isn't.

Thought it was a retraining issue?
