Introduction: scope and justification

it is known that the area aroundFiras Circle. Is one of the most

important regions in Amman city thats for a lot of reasons

including: -

1- Existence of Market Hussein

2- The area is filled with shoppers

3- This region is filled with hotels , restaurants; net cafs; game

shops coffee shops and of course a high population area

4- And a lot more reasons..

For those reasons a very annoying traffic jam is now a daily event

on Al-Hussein street "crowded traffic and accidents " which make a

lot of people wait for a really long time to get their homes ; class;

work places and other places

so we have considered to remove this jam but how !!!

the main target is to separate people going to Entertainmentspotsso we decided to build a tunnel under the existing Firas Circleand

remove the rotary which that would solve a very large part of our

problem and will not be stuck there for along time again.

Success and failure criteria:the project is considered successful if the traffic jam is reduced by

75 % for at least the next ten years and done by planned time>

If not the project is considered a failure.

b- Strategic choices :time and quality is the most important strategic choices that wecare about as we see in fig 1

Fig 1 time and quality priority

c- Requirements of the project :

Input req. Process req. Outcome req.Shortest time Good work staff Traffic jam End

High quality Good teamwork Nice view

Good budget Firm work times Less accidents

Specified location equipment serve for very long time

Best designers Fast execution

d-Initial planning :

After getting the legal approval we start by closing the road

and making detour, then removing the rotary, cleaning area,

excavation operations and then foundation and columns are

to be laid.

in the mean while parts of tunnel are to be ready (beams) to

put on top of the columns and then we joint them together

and asphalting the tunnel .

We must take a look for the signs, lights and safety

measures.

The project will start 26/5/2012 and expected to be finished

01/8/2012.

= = 7.759847937 days

*We use more than one program to do calculationfirst of them we use Microsoft

after that we check by Matlab and Microsoft Excel

programs

*We used the Excel program to plot Beta distribution*we check by using website adrees given in slides

Finishing probabilities

Req. =65

*probability of finishing the project in time:

z = = 2.15855

Area corresponding to z = -2.15855 from tables 0.01545

* Probability of finishing the project in 90% of the time:

90 % of original time = 58.5 days

z = = 3

Area corresponding to z = 3 from tables 0.00135

First able we most know the normal and crash cost and time to

calculate and get the cheapest crash way available:

T = time in days

c = cost in J.D.

We used law:

Crash cost - Normal costNormal time crash time

We want to complete project in 75 % of its

estimated time so:

want to crash 17 days of critical path.

We have the approach of "crashing of activities"

*we start by the critical path

B) 1-2-3-4-5-6-8-9-10-11-12-13-14-15-16-17-18-23-24-25-26-27 = 65

This is what we start with

so:

we have considered the cheapest crash cost per

crash time

we notice that a lot of our reduced tasks are in

other tasks we hit two birds with one stone "

20


21/26

1- Crash 2 days from activity # 3

total cost = 6510 + 2(12.5) =6535

2 Crash 4 days from activity #18

Total cost = 6535 + 4(32.5) =6665


Total cost = 6665 + 2(35) =6735


& crash 2 days from activity #12

Total cost = 6735 + (2+2) (50) =6935


Total cost = 6935+ 2(60) =7055


Total cost = 7055+ 5(75) =7430

21


22/26

So our paths now:

A) 1-2-3-4-5-6-7-9-10-11-12-13-14-15-16-17-18-23-24-25-26-27 = 46

B) 1-2-3-4-5-6-8-9-10-11-12-13-14-15-16-17-18-23-24-25-26-27 = 48

C) 1-2-3-4-5-6-7-9-10-11-12-13-14-15-16-17-18-21-22-26-27 = 46

D) 1-2-3-4-5-6-8-9-10-11-12-13-14-15-16-17-18-21-22-26-27 = 48

E) 1-2-3-4-5-6-7-9-10-11-12-13-14-15-16-17-18-20-22-26-27 = 46

F) 1-2-3-4-5-6-8-9-10-11-12-13-14-15-16-17-18-20-22-26-27 = 48

G) 1-2-3-4-5-6-7-9-10-11-12-13-14-15-16-17-18-19-22-26-27 = 46

H) 1-2-3-4-5-6-8-9-10-11-12-13-14-15-16-17-18-19-22-26-27 = 48

22


23/26

Source leveling:

Now in our projects we need to deal with workers

as little as we can and as less time as we can also:

tasks 21 and 23 are concurrent and 23 is in the

critical path and each needs 4 workers the whole

time until it finishes :

8 8 8 8

23

23

21


24/26

so by source leveling and without wasting any

time we move task 21 3 days as its slack give uspermission to reduce # of workers to 4 each day

accept one day :

4 4 4 8 4 4 4

IMPORTANT NOTE:

All calculations were done at our hand and we

check by using programs

First of these programs are Microsoft project

also we done it by matlab and Excel

Each student in this project had taken one of

these programs and he was done calculations to

ensure that all student work in team and all of

whom participated in the completion of the project
