PROBLEM DEFINITION Problem hypothesis of Kota Kasablanka Mall Parking System
And how it will affects?
If PT Secure Parking Indonesia in Kota
Kasablanka Mall ignores this problem, there will
be a decreasing number of customers in the
motorcycle parking area of Kota Kasablanka
Mall due to the difficulty in looking for parking
space.
What is the symptoms?
Since September 26th, 2015, the motorcycle parking
area in Kota Kasablanka Mall is having problem
due to the over capacity of the parking area,
queueing in arrival line, and queueing to find
parking spaces that makes customers unsatisfied.

OBJECTIVES OF THE RESEARCH
Determine when the peak time of arrival number in Kota Kasablanka Mall Parking
Spaces, in range 6 hours.
To know how much arrival rate and service time in Kota Kasablanka Mall Parking
Spaces when peak time
1.
2. 3.
7.
5.
To know how long the average waiting time for one visitor in counter of Kasablanka
Mall Parking Spaces when peak time
6.
To know how long queueing rate in counter of Kasablanka Mall Parking Spaces when
peak time
4.
Making reccomendation related to number of server to reduce queuing time on one
customer before she/he is served in counter (into 2 minutes)
Making reccomendation related to parking capacity to reduce queuing time of one
customer before get the parking (into 2 minutes)
Making discrete event modeling and comparing with spreadsheet model
The objectives are used to answer the questions

DATA COLLECTION & ANALYSIS When are the peak days and peak hour of Kota Kasablanka Mall Parking Spaces?
We used online survey and advanced
judgement to know when is the peak days
of parking spaces
From online survey we got Saturday as a peak day also
proved by result of advanced judgement
From the result of direct observation we got distribution of
arrival rate that showed from graphic below

So the 6 peak hours are Saturday at 11.00 – 12.00,

These are the conclusions which also represent as the answer for the research objectives
Here is the model and the data comparison between promodel and spreadsheet

Then those
statements lead to
a final conclusion
that our
Hypothesis for
Mall Kota
Kasablanka
Parking System is
DENIED
These are the suggestion for Kota Kasablanka Parking Spaces
SUGGESTION
Actually there are
nothing wrong with
Kota Kasablanka’s
Parking System.
The model do not
show a
significant
number of
waiting time
both when in the
queue for the
check in counter
(average 0.16
min) or when they
search for a
parking spot (1
min)
The current
number of server
used is also not
really a problem,
because there’s not
a significant
number of people
in the queue. So,
we think it’s best
for now just to use
one server per
gate.
The current total
capacity is 1755
spots, which is a
huge number of
capacity for a
parking lot. So, for
now Mall Kota
Kasablanka do
not have to add
the capacity of the
parking lot,
because it is
already sufficient
