Exercise 2

Problem: No way to know if your train is currently running on schedule

Solution: Terrific Train Tracker! (TTT)

Objective: Create an app that monitors the real-time progress of trains as they travel on the line.

Background: NJ Transit is notorious for running behind schedule, as are some other railways such as British Rail. Derailments or problems with the track can also cause delays lasting hours.

Methodology: RFID sensors along the track could scan tags installed on the trains to give an accurate location of each train as well as an estimate as to when it will arrive at its destination. The app would convey this information to the user as well as any alerts about problems with the train.

Expected Results: Users will have accurate information as to how close their train is to the station, or if it has run into a problem. This will help prevent them from missing a train or decide whether they should seek an alternate form of transportation.

Costs: $99 app liscensing fee + cost of RFID tags and sensors.

Exercise 3

Problem Statement: There is no way to tell precisely when a train will arrive at its destination.

Statement-Restatement: Currently there is no method in place to track the locations of trains and relay how far away from the station they are to customers, therefore RFID sensors should be used to track each train and relay its progress to waiting passengers.

KT-Problem Analysis

Exercise 4

Tasks:

Install RFID tags on trains

Install sensors along tracks

Design an app to communicate train location and other travel information to customers

Goals:

Track the location of trains in service

Provide all relevant information to passengers

Improve their ability to make an informed choice as to what mode of transportation they should utilize

Exercise 5

RFID Tag - Patent USD763833S1

Exercise 6

The system model for this app would be deterministic and would appear as follows:

Descriptive Process Model:

RFID sensors would pick up the RFID tags installed on each train, and use this information to communicate the location of each train to the app. Customers using the app would be able to search for their train and see its location, how far from the station it is, and any other relevant data for the train.

Exercise 7

Exercise 8

Potential Hazards:

Hackers could steal information about which trains customers take and use this information to track them

Changes:

RFID equipment may be replaced upon failure or discovery of a better replacement

Disposal:

RFID equipment may be disposed of in the same manner as other electrical waste

Exercise 9

Solutions:

App could use the same type of security that similar apps use to prevent data leak
Design should use the latest in RFID technology to prevent it from becoming obsolete
RFID equipment could be recycled after failure
