Problem Formulation

�

�

�

�

With such high visitors coming to MallAmbassador and many of them drive cars,this Mall only provides small spaces forparking – only 360 parking spots available– causing a queue when entering the parkingspot and difficulties in finding the parkingspot, especially on peak time.

Problem Statement

�

�

�

�

7

Make the model based on the data weobtained from observation. Based on themodel we can conclude whether theparking system of Mall Ambassador isalready optimum and met the criteria thathad given previously.

Validation and Verification

36

�

�

�

�

01 Watching the animation

02 Comparing with other models

03 Conducting degeneracy and extreme condition test

��

ValidationWe use these following techniques for validating the model:

04 Performing sensitivity analysis

05 Running trace

37

�

�

�

�

Watching the Animation

After the model was done, we have to run the model to see whether the model is correct or not.

Comparing with Other Models

We have to make sure the model is correct bycomparing with the excel data. After we run the model,we can see the statistic, if the number is the same withthe excel calculating, then our model is finally correct

40Conducting Degeneracy and Extreme Condition Test

In conducting degeneracy and extreme condition test we can change the arrival rate. Assume that we change the arrival rate to 0 (zero) following with the accuracy, then the result should be:

No car arrive in the entry queue. If it is happened, then our model is

finally correct

�

�

�

�

In performing sensitivity analysis, we can try to change the service time, if we change into the smaller number of service time there will be no queue, if we change into bigger number there will be queue. After we try, our model adjust with the changing of numbers, it means the model is correct

Performing Sensitivity Analysis41

�

�

�

�

�

42

Running Trace

Running trace will show all of the event on the discrete model.

There is no error on our model, based on the trace results

�

�

�

�

43

�

�

�

�

01 Reviewing model code

02 Checking for reasonable input and output

03 Watching the animation��

Verification

In order to verified the model, we use some techniques:

04 Using trace and debugging facilities

Reviewing Model Code44

�

�

�

�

Checking for Reasonable Input and Output45

�

�

�

�

The number of entry car is same as the number of exit car and the number of car at the current location, so input and output

are reasonable.

Watching the Animation

We can know that the model is correct if the model is running until it’s done correctly and without bug.

46

�

�

�

�

47

Using Trace and Debugging Facilities

We use trace and debugging facilities to make sure we build the model correctly implemented with good input and structure.

There is no error on our model, based on the trace results. There is no debugging in our model.

Results and Recommendations

49

�

�

�

�

01 The peak time is at 11.00-17.00

02-Arrival Rate at peak Time: P(195;41.8) sec

-Service Time at peak Time: L(5.94;0.69) sec

03 Average waiting time in queue: 0.15 sec

��

ResultsOur Result is:

04 Average cars in queue: 0.01

05 The data from spreadsheet is same with the data from promodel

50

�

�

�

�

01 The capacity should be increased by 25 parking slot to meet the requirement.

02 The number of ticket locket is enough to meet the requirement.
