The Case - Go “MOBILE” Locker is coming to the campus.
The CEO of Go Locker has decided to explore the deployment of “MOBILE” lockers
to Nanyang Technological University (NTU).
With Internet making online shopping experience easy and enjoyable, the use of self service lockers has become popular and a possible business opportunity for Go
Locker to service students studying in big campus like NTU.
Currently in NTU, students can only one locker at a fixed location. However, with
student studying different modules each semester, not all lecture halls and classrooms
can be close to the locker location. Hence, a fixed location locker make it
inconvenience and troublesome to access, due to “tourism” and heavy human traffic
between lesson.
Combining the use of electric track transport system (not-in-scope), student can
access their “MOBILE” locker at any available Go Locker stations. For example,
students can request to “send” their lockers to a station nearest to their next lesson,
collect and store items before next lesson.
In the pilot phase, Go Locker will allow student to rent up to 2 lockers, at $2 per locker.
Student can release/return the locker anytime. Each request to move locker to a
specified station will incur 20 cents. When a locker is moved to the specified station,
student can proceed to access/open the locker.
As an intern in IMDA (Infocomm Media Development Authority), your supervisor has
assigned you to help Go Locker with this pilot project, with objectives to automate the
mobile locker rental and operations processes.
Project Requirement
After extensive discussions, Go Locker would like to have the following essential
features to be included:
System Admin functionalities that featured creation of station, locker,
updating of locker details, and reports for station, locker usage.
Station Operations/functionalities that include rent/return locker, request
locker moves, enquiring locker location and viewing of usage report.
Further features to be integrated in the application are configurable rental
fees, moving fees, and a background program to process the “moving” of
lockers (see BONUS features).
Based on you understanding, the pilot project will have 2 applications: one to allow
Go Locker administrators to perform administrative functionalities, and the other for
students to perform locker operations.
1. Go Locker – Admin
For the Go Locker administrators, the application should display the following
menu:
^^^^ Go Locker - Admin ^^^^
1. Setup station
2. Create locker
3. Update locker
4. View station report
5. Track locker usage
0. Exit
Enter option:
Before presenting the menus, your application needs to load/pre-setup the
stations, lockers, students from Appendix A and rentals (if any) into collections*.
* Your group can decide to implement using either Dictionary or List.
a. Setup station
This function allows the administrator to setup a new station.
To setup a new station, the following data elements should be collected:
Station Code: should be unique, in format of NTU-XXX-DD, where XXX
represents the building code (e.g., N21, S32), and DD represents digits
from 00 to 99.
Station Name: name description of the station (e.g., The Hive level 1, The
Arc level 2)
Rows: number of rows for this station
Columns: number of columns for this station
Status: Open or Closed
The maximum number of lockers for this station will be Rows X Columns.
Hence if station NTU-S32-01 has 4 rows and 20 columns, the capacity for
this station is 80 slots. Therefore, your application may need to include a
collection to represent the 80 slots. These slots will be empty, until student
request to move their locker into the station.
When a new station is created, the status should be defaulted to “Open”. The
new station will be added into the collection and updated into “Stations.txt”
file.
b. Create locker
Locker can be added into the system to meet the demand. To add a new
locker, these data elements should be collected:
ID: starting from 10001, increment by 1 for each new locker created
Location: “Central store”, “In transit”, or any valid station code. Defaulted
to “Central store” at creation.
Row: default to empty/zero unless the locker is in a station.
Column: default to empty/zero unless the locker is in a station.
Status: “Occupied”, “Available” (default), “Suspended”.
Rental ID: if “Occupied”, need to record the rental ID.
When a new locker is created, then locker should be added into the collection
and updated into “Lockers.txt” file.
c. Update locker
The “Update Locker” option allows the administrator to update the locker’s
details:
User should first provide the locker ID to search.
If there is no locker with this ID, display appropriate error message and
return to menu.
If the ID is valid, your program should display the locker details, and if
occupied, the student ID, student name and date started renting this
locker.
Only allow update to Location and Status.
However, status can only be updated to “Suspended” when current Status
is “Available”. When updating Status from “Occupied” to “Available”, the
rental record needs to be terminated.
Any updates should also be affected into “Lockers.txt”
d. View station utilization report
The option allows the administrator to view the current station utilization.
User should first provide the station code to search.
If there is no station with this code, display appropriate error message and
return to menu.
If the station code is valid, your program should display the station details,
and a table showing all the slots (rows x columns) – with locker IDs for
those slots that contain the students’ lockers.
e. Track locker usage
The option allows the administrator to track the operations of a specific locker.
User should first provide the locker ID to search.
If there is no locker with this ID, display appropriate error message and
return to menu.
If the ID is valid, your program should display the locker details, and if
occupied, the student ID, student name and date started renting this
locker.
Your application should ask for the Date-From and Date-To, before
generating the report containing all operations for this locker during the
specified dates.
Below is a demonstration of the generation of “Track locker usage” report:

2. Go Locker - Operations
For the students, the application should display the following Operations menu:
++++ Go Locker – Operations ++++
1. Rent a locker
2. Request move
3. Return locker
4. Enquire locker location
5. View usage report
0. Exit
Enter option:
Before presenting the menus, your application needs to load/pre-setup the
stations, lockers, students from Appendix A and rentals (if any) into collections*.
* Your group can decide to implement using either Dictionary or List.
a. Rent a locker
To rent a locker, students only need to provide their student ID.
If the ID is valid, your program should display rented locker details (if any),
and if student is renting 2 lockers now, display appropriate error message
and return to menu.
If student can still rent a locker, your program will locate an available
locker and create the rental transaction, charging $2 to the student
account.
Rental transaction should include the locker ID, student ID, start date and
end date (default to None, until the rental is terminated).
Your program should generate a unique Rental ID (running number) and
display the rental details.

b. Request move
To start moving a locker, the student ID and locker ID must be provided:
Your program must validate both student ID and locker ID.
If the IDs are valid, your program should display rented locker details.
If not, display appropriate error message and return to menu.
Prompt for the station code to move to.
Create the move transaction record if,
The station code is valid and is not same as current location.
The destination has slots for this locker, hence displaying “Station
Code (Row-Column)” for this move. For example, “NTU-N31-04 (1-09)”

To show your ability in coding, your supervisor gave you the flexibility to design the
structure and interface. Now, you shall apply what you have learnt in the school into
practice.
More (BONUS) features for consideration:
You should explore problem solving techniques to design a solution to allow:
a. Dynamic, configurable setup of rental fees and moving fees. Aim is not to re code and restart application for any changes to rental fees and moving fees.
b. Have a background program processing the locker move requests.
When a student request for a locker moves, this transaction will be
recorded and processed by your background program.
The locker location will be updated accordingly after 3 min, simulating the
movement of the locker vis the electric track delivery system.
Hence, it will be “In transit”, follow by e.g., “NTU-N32-11” after 3 min.
Locker move requests can also be initiated by the system, 30 min after
the locker has arrived at a station. This is to manage space/slot, ensuring
there are slots at each station to serve students.
