We are pleased to announce that PETRÓLEOS DE VENEZUELA S.A. (PDVSA) selected HAVERLY SYSTEMS to implement a corporate wide crude assay data management system for PDVSA and Citgo Refining.
PDVSA required a comprehensive solution that would make crude data available to its refineries and headquarter locations in Venezuela, Citgo's refining operations in the United States and PDVSA's European operations in London.
The solution they selected consists of Haverly's H/CAMS Crude Assay Management System, Chevron's Worldwide Crude Assay Library, and Haverly's H/COMET internet based Crude Oil Management Evaluation Tool.
With the Haverly solution, crude assay data will be available on a corporate server that can be accessed by various groups with differing needs. These would include planners and engineers requiring detailed assay data for use with their LP and Process Simulation systems. Others would include traders and marketers needing to quickly and easily find crudes that meet specified criteria. The system provides a number of valuable functions, including the ability to determine the netback value of crudes for a variety of refinery configurations and the ability to optimize crude blends.
To find out how we may be able to provide similar solutions at your company call Ken Spencer, (973) 627-1424. (17May06)

10Unscathed by infeasibilities or non-convergence issues: A true LP warrior. 9Few, if any, calls to Haverly for Tech Support; Calling Randy to talk motorcycles, Don to locate shareware, Dean to find downtown Houston discos, or Ken to complain about price increases don't count! 8Appearances are a dead giveaway; Grey, thinning & often balding hair; Deep, dark cavernous circles under the eyes (Look around the room!). 7Sneaks out of the office once a week to visit psychiatrist for obsessive, compulsive disorder. 6At parties, can't carry-on conversations with non-LP people who just don't understand how difficult the LP job really is. 5While LP is solving, pops Zanex & Prozac, chugs Pepto-Bismal and chews Immodium AD for breath mints. 4Attends sleep disorder clinic for sleep apnea, only to be diagnosed with nightmares associated with LP vectors. 3Tells significant other can't go to bed because of work, only to stay up late solving Su Doku puzzles. 2At the coke machine, won't pay $1.00 for 20 oz coke when the 12 oz coke is $0.50 because it's suboptimal. 1LP problems actually turn out to be a Haverly BUG!

Dean Trierwiler (Haverly Systems) and Vince DiVita (Jabobs Consultancy) were published in the May/June 2004 issue of Hydrocarbon Asia. Their article, The New LP, begins by laying a foundation of history describing how the newest technology has completely changed linear programming. The New LP is described by Trierwiler and DiVita as non-linear without compromise, reliably convergent, and able to perform true cut-point optimization. (7/9/04)
Larry Haverly has had a chapter published in the Applied Optimization series of book. It is in a book on Modeling Languages. In the chapter, Larry describes the history and power of the OMNI modeling language and the new developments and future direction of support.Larry says, "I see OMNI as still one of the finest and most useful of modeling languages for large, commercial LP type applications. It plays a vital role in our advanced application systems for refinery planning and scheduling." The book is available from Kluwer Academic Publishers, 56 Industrial Park Drive, Pembroke, MA 02359 and lists for $280. (24 May 2004)

A ball is dropped from a height of 10 feet. It bounces off the floor up to a height of 5 feet. Each successive bounce is half as high as the previous. Assuming the ball moves only vertically, what is the total distance travelled by the ball? (5/12/3)
An elderly woman and her little grandson, whose face was sprinkled with bright freckles, spent the day at the zoo. Lots of children were waiting in line to get their cheeks painted by a local artist who was decorating them with tiger paws.
"You've got so many freckles, there's no place to paint!" a girl in the line said to the little fella.
Embarrassed, the little boy dropped his head. His grandmother knelt down next to him. "I love your freckles. When I was a little girl always wanted freckles, she said, while tracing her finger across the child's cheek.
"Freckles are beautiful!".
The boy looked up, "Really?"
"Of course," said the grandmother. "Why, just name me one thing that's prettier than freckles."
The little boy thought for a moment, peered intensely into his grandma's face, and softly whispered, "Wrinkles."

After putting her children to bed, a mother changed into old slacks and a droopy blouse and proceeded to wash her hair. As she heard the children getting more and more rambunctious, her patience grew thin. At last she threw a towel around her head and stormed into their room, putting them back to bed with stern warnings. As she left the room, she heard her three-year-old say with a trembling voice, "Who was THAT?"
**************
A little girl was diligently pounding away on her mom's word processor. She told her she was writing a story.
"What's it about?" she asked.
"I don't know," she replied. "I can't read."

A second grader came home from school and said to her mother, "Mom, guess what? We learned how to make babies today."
The mother, more than a little surprised, tried to keep her cool. "That's interesting," she said, "How do you make babies?"
"It's simple," replied the girl. "You just change 'y' to 'i' and add 'es'." (5/7/3)
Jeff Stanton sent in this solution to the puzzle in which you have to pick one of three doors to open and only one has the prize. If after you pick a door, they open one of the other doors to show it has no prize and then allow you to either keep your original pick or change it, what should you do?
Maybe you think the probability of winning by keeping or by changing your pick is the same 50% but think again.
Jeff writes; "I have another simple way to think of this problem from your News page. When you pick a door, you have a 1/3 chance of being right, and a 2/3 chance of being wrong. When the host opens the other door, the odds don't change. You still have a 1/3 chance of being right, and a 2/3 chance of being wrong. Therefore, you should switch to take a 2/3 chance of being right. Of course, this only works if the host always opens a door and allows you to switch. Later versions of the show didn't always allow contestants to switch, eliminating the advantage." Check all the combinations and you will see this is correct in spite of your intuition. Thanks Jeff.

GRTMPS is widely used as a planning tool doing monthly and longer range planning. It is excellent for determining the best crudes to buy to meet the best product slate within the flexibility of the refinery.
But the same GRTMPS system can be used to do short term, multi-period modeling (STM). The periods might be weeks or a mixture of periods of different lengths. The model might be set up as four week periods to cover a month. Alternatively, the periods could be 4 days, 4 days and balance of the month, for example. An interesting possibility for a refinery receiving a few major multi-crude cargos per month is to define the periods as the time between crude tanker arrivals.
The point is that you can use the standard GRTMPS system and define your short term model as appropriate for your situation. By using a common data base, the development and support effort is greatly reduced and the application becomes practical and economically.
STM GRTMPS can stand between monthly planning and the powerful, advanced scheduling system, H/SCHED (with its own scheduling optimization and schedule generation).
Just as the same GRTMPS system can be used to optimize both the single refineries models and a multi-refinery model of the refineries, so can the same GRTMPS system be used for a both a monthly model and a multi-period short term model.
Add in the new object oriented, user friendly input and the connectivity to process simulators, GRTMPS is simply the best choice for doing a wide range of refinery optimization situations. If you are not using GRTMPS you are not using the latest and best. (4/14/3)
Our employee Dr. Yunhui Pu recently published a book with other two authors, Prof. Tianmin Guo and Dr. Wei Yan.

Dr. Yunhui Pu was responsible for the Distillation Algorithm section especially the chapters on bubble and dew point calculation, flash calculation, Inside-Out algorithm, nonequilibrium stage algorithm, and introduction of commercial process simulators. (2/4/03)
Question: The paradox "Three Doors Problem" is related to a television show in the 70's: Monty Hall's "Let's Make a Deal". In this popular show, a finalist was given a choice of three doors of which only one contains the big prize. Behind the other two doors there was nothing.
After the finalist chose one of the doors, the quizmaster then revealed one "empty door" among the two doors that were not chosen. After that, the quizmaster asked if the finalist would like to switch to the other door to open.
The question: What should you do? Do you open the door you initially chose or do you switch to the other unopened door before? Do the odds of winning the game increase by switching to the remaining door?
This puzzle is responsible for countless arguments among zealous puzzle solvers. Think you know?
Answer: You may be surprised! http://plus.maths.org/issue5/puzzle/solution.html

Check yourself. Read the questions and answer each immediately. Answers below.
1. You are competing in a race, and overtake the runner in second place. In what position are your now?
2. Try to do better on this one. If you overtake the last runner, what position are you now in?
3. Oh well, maybe you will do better at solving math in your head (no calculators).
. Take 1000. Add 40. Add another 1000. Add 30. 1000 again. Plus 20. Plus 1000 Add plus 10. What is the total?
4. Last chance. Marie's father has five daughters:
1. Chacha
2. Cheche
3. Chichi
4. Chocho
5. ????
What is the fifth daughter's name?
Answers:
1. If you answered that you are in first then you are completely wrong. You overtook the second place runner and now you are second.
2. How can you overtake the last runner. If you are behind then they are not last.
3. 5000??? That's wrong. The correct answer is 4100.
4. Chuchu???? No way. It's obviously Marie. Read the question. (7/17/02)

We hope all our existing and prospective clients will be pleased with the results and we welcome feedback, ideas and requests at all times. (6/20/2)
You are driving along on a wild stormy night. You pass by a bus stop, and you see three people waiting for the bus: 1. An old lady who is very sick. 2. An old friend who once saved your life. 3. The perfect man(or)woman you have been dreaming about.
Which one would you choose, knowing that there could only be one passenger in your car. This is a moral/ethical dilemma that was once actually used as part of a job application.
You could pick up the old lady, because she is sick, and thus you should save her first; or you could take the old friend because he once saved your life, and this would be the perfect chance to pay him back. However, you may never be able to find your perfect dream lover again.
Think before you continue. The candidate who was hired (out of 200 applicants) had no trouble coming up with his answer which is given below. (5/14/2)
He simply answered: "I would give the car keys to my old friend, and let him take the lady to the hospital. I would stay behind and wait for the bus with the woman of my dreams." (5/14/2)
HSI staff members Dean Trierwiler and Dr. Richard Tan were published in the Nov/Dec 2001 issue of Hydrocarbon Asia. The article is entitled "Advances in Crude Oil LP Modelling". It describes the advantages and details of the Adherent Recursion technique added to the GRTMPS optimization planning system. It also describes the success from close integration of GRTMPS and the H/CAMS crude assay data management system to achieve better non-linear cut point and crude selection optimization. These advances can result in substantial savings to users. (3/10/02)
