CLASS PROJECT

THE CLASS PROJECT BELOW INCLUDES TWO CASES. FOR FULL CREDIT,

WRITEUPS FOR BOTH CASES MUST BE COMPLETED!!!!!! FOR EACH CASE,

INCLUDE A BRIEF SUMMARY OF THE CASE, A MODEL FORMULATION, ANY

COMPUTATIONS AS APPROPRIATE, AND AN ANALYSIS OF RESULTS. IN-

CLUDE ANY RECOMMENDATIONS AND CONCLUSIONS YOU FEEL ARE APPROP-

RIATE. REMEMBER TO COMPLETE BOTH CASES!!!!!

NOTE THAT THE PROJECT IS GRADED OUT OF 20 POINTS - 10 POINTS

FOR EACH CASE!!!!

10 PTS. I) THE TEN STARS AMUSEMENT PARK

THE TEN STARS TRAVELING AMUSEMENT PARK HAS RECENTLY SET UP OP-

ERATION IN THE EAST BAY. THE ARRIVAL RATE OF PATRONS AT THE

PARK IS ESTIMATED AS 30 PER HOUR. THERE IS ONE ADMISSIONS GATE,

STAFFED BY A SINGLE WORKER. ADMISSIONS CAN BE CONDUCTED AT AN

ESTIMATED RATE OF 35 PER HOUR. FORTY PERCENT OF PATRONS GO

DIRECTLY TO THE FERRIS WHEEL, WHILE THE OTHER SIXTY PERCENT

GO TO THE ROLLERCOASTER. THE SERVICE RATE OF THE FERRIS WHEEL

IS 15 PATRONS PER HOUR, WHILE THE SERVICE RATE OF THE ROLLER

COASTER IS 24 PATRONS PER HOUR. ALL OF THE PATRONS LEAVING

THE FERRIS WHEEL GO TO THE HOUSE OF MIRRORS. IN ADDITION,

THIRTY PERCENT OF PATRONS LEAVING THE ROLLER COASTER GO TO

THE HOUSE OF MIRRORS. THE HOUSE OF MIRRORS SERVES PATRONS

ONE AT A TIME AT A RATE OF 20 PER HOUR. ALL PATRONS LEAVING

THE HOUSE OF MIRRORS AS WELL AS REMAINING PATRONS LEAVING

THE ROLLERCOASTER ALL GO TO THE EXIT GATE. THERE IS ONE

WORKER AT THE EXIT GATE, WHO CAN PROCESS EXITING PATRONS AT

A RATE OF 37 PER HOUR. IT IS DESIRED TO DETERMINE FOR THIS

AMUSEMENT PARK, THE EXPECTED NUMBER OF PATRONS WAITING AT

THE ADMISSION GATE, EXIT GATE, AND AT EACH RIDE. IT IS ALSO

DESIRED TO DETERMINE THE EXPECTED TIME PATRONS SPEND WAITING

AT EACH OF THESE LOCATIONS. IF AN ADDITIONAL WORKER WAS

AVAILABLE, AT WHICH "STATION" (I.E., ENTRY GATE, EXIT GATE,

OR RIDE) SHOULD THIS WORKER BE PLACED?

THE DEPT. OF PUBLIC SAFETY FOR ALAMEDA COUNTY WOULD LIKE TO

KNOW WHAT THE AVERAGE NUMBER OF PATRONS IS EXPECTED TO BE

IN THE PARK OVER THE COURSE OF A DAY IN ORDER TO DETERMINE

WHETHER THIS MEETS WITH SAFETY REGULATIONS. CURRENT REGULAT-

IONS DO NOT ALLOW FOR MORE THAN 25 PATRONS IN THE PARK AT ANY

ONE TIME. WHAT WOULD YOU REPORT FOR THIS? (I.E., IS THE RE-

QUIREMENT MET?) (NOTE THAT YOU CAN TREAT EACH STATION AS

A SINGLE SERVER SYSTEM!!!!!) MAKE SURE TO SHOW YOUR CALCULAT-

IONS AND REPORT YOUR RESULTS REGARDING PARK OPERATIONS.

A) WRITE A SHORT SUMMARY OF THE CASE, INCLUDING THE PURPOSE

OF YOUR ANALYSIS.

B) SHOW AND EXPLAIN THE MODEL YOU USED TO EVALUATE THE AMUSE-

MENT PARK SYSTEM.

C) SHOW ANY CALCULATIONS YOU USED TO OBTAIN YOUR RESULTS.

(HINT: FOR EACH GATE AND RIDE YOU WILL NEED L, Lq, and Wq.)

D) DISPLAY A SUMMARY OF RESULTS.

E) ANSWER ANY QUESTIONS POSED WITH THE CASE IN ADDITION TO

THE SUMMARY OF RESULTS. (I.E., AT WHAT RIDE WOULD YOU PLACE

AN ADDITIONAL WORKER, AND ARE PARK LIMITATIONS ON PATRONS

BEING MET?)

F) WRITE A BRIEF CONCLUSIONS AND RECOMMENDATIONS. A FEW

SENTENCES WILL SUFFICE.

10 PTS. II) THE MAIN STREET DELI - ROTISSERIE CHICKEN

THE MAIN STREET DELI IN HAYWARD PREPARES ROTISSERIE CHICK-

EN FOR PATRONS WHO COME IN AT THE END OF THE DAY AFTER WORK.

CURRENTLY, THE DAILY DEMAND FOR THESE ROTISSERIE CHICKENS

AT THE END OF THE DAY HAS BEEN FOUND TO BE DISTRIBUTED AS

FOLLOWS (BASED ON HISTORICAL DATA):

#ROTISSERIE PERCENT

CHICKENS OF DAYS

0 .10

1 .30

2 .30

3 .15

4 .15

THE DELI IS NOT CONSISTENT WITH REGARD TO HOW MANY OF THESE

CHICKENS THEY CAN BAKE DAILY. THIS IS BECAUSE THEY HIRE A

NUMBER OF C.S.U.E.B. STUDENTS TO WORK DAILY, AND SOME ARE

NOT AVAILABLE BECAUSE OF SCHOOL COMMITMENTS.

BASED ON PAST DATA, THE NUMBER OF CHICKENS WHICH CAN BE

BAKED ON A GIVEN DAY IS DISTRIBUTED AS FOLLOWS. NOTE THAT

IF ON ANY DAY AN EXCESS OF CHICKENS ARE BAKED, THEY WILL

BE DISPOSED OF AND CANNOT BE SAVED FOR LATER USE. ALSO,

IF THERE IS AN EXCESS OF DEMAND ON ANY GIVEN DAY, THIS

DEMAND WILL BE LOST.

# CHICKENS

BAKED PERCENT OF DAYS

2 .50

3 .30

4 .10

5 .10

THE ROTISSERIE CHICKENS ARE SOLD FOR $10 EACH, AND COST $3

TO BAKE. CONDUCT A SIMULATION OF CHICKENS BAKED AND SOLD

DAILY FOR 30 DAYS. YOU CAN USE THE RANDOM NUMBER TABLES

IN THE CLASS HANDOUT ON SIMULATION, OR ANY OTHER SOURCE OF

RANDOM NUMBERS YOU CHOOSE!!!!!! (NOTE THAT YOU WILL NEED

SEPARATE RANDOM NUMBERS TO GENERATE THE NUMBER OF

CHICKENS BAKED DAILY, AND THE DAILY DEMAND FOR CHICKENS!!)

A) DEFINE YOUR RANDOM NUMBER RANGE TABLES.

B) SHOW YOUR SIMULATION TABLE. INCLUDE COLUMNS FOR

- THE NUMBER OF CHICKENS BAKED DAILY

- THE DAILY DEMAND FOR BAKED CHICKENS

- THE NUMBER OF CHICKENS SOLD DAILY

- EXCESS CHICKENS BAKED DAILY (NOT SOLD)

- SHORTAGE OF CHICKENS DAILY (UNMET DEMAND)

C) BASED ON YOUR SIMULATED RESULTS, WHAT IS THE AVERAGE

DAILY PROFIT MADE? SHOW YOUR CALCULATION.

B) HOW MUCH DEMAND FOR CHICKENS IS LOST, AGAIN ON AN AVER-

AGE DAILY BASIS?

C) HOW MANY CHICKENS ARE DISPOSED OF, AGAIN ON AN AVERAGE

DAILY BASIS?

D) DO YOU BELIEVE YOU ARE BAKING TOO MANY CHICKENS RELATIVE

TO DEMAND? EXPLAIN YOUR REASONING.

MAKE SURE TO SHOW YOUR SIMULATION TABLE AND THE RANDOM NUM-

BERS YOU ASSIGNED.
