Disaster Relief Challenge….Provide Ice
Goals and Objectives: For the challenge below, show how today’s tools can be used and integrated together to support planning, analysis, decision making, communications, and documentation and reporting while minimizing duplication of effort, or data entry. Refer to the listing of Goals and Objectives posted on the TVC page for a full listing of all Goals and Objectives to consider including as part of your demonstration.
Challenge: It is summer time in Pleasantville, a rural US town located in a temperate climate zone currently experiencing temperatures ranging between 70 – 100 degrees Fahrenheit (20-35 C). A recent natural disaster has devastated the area within a 100 mile radius. An estimated 3000 people lost their homes due to the destruction, and need to find shelter. Most roads are impassible to the public so there is limited vehicle transportation and the electricity is out in most of the disaster area. As part of emergency response requirements, shelters must be set up within 24 hours from when the evacuations begin to help sustain those who need to relocate. As part of the initial emergency response, ice must be provided to sustain perishables such as medicine and foods, and to support first aid needs. Power and potable water are to be provided with the shelter solution.
Alternatives: The following options to provide ice are considered. Provide ice by making it at the shelter which would require the use of water, power, and ice making and storage facilities. Alternatively, provide ice is by procuring it, which would require a method for transporting and storing the ice.
Show how tools can be used to capture, communicate, document, and report the following data to stakeholders: requirements, architecture trade-offs, and traceability to the selected architecture.
Develop Requirements: Capture requirements for providing shelter, power, food, and supplies including ice. Keep in mind that the ice to be provided must support 3000 people. Also keep in mind that health standards analysis states that between 2 pounds to 4 pounds of ice per day are needed to sustain each person.
Compare and select your desired operational scenario: As the requirements are being derived, develop the scenarios representing the operational behavior for each of at the two alternatives identified above. As part of the comparative trade study between these two alternatives capture performance requirements and risks related to cost and schedule as an input to support evaluation of the trade study alternatives. Also, capture the importance of each attribute to support the trade study.
Develop Architecture. Capture the alternative approaches in the system architecture. Show how the tools support the trade study to make the applicable decision and collect trade information as indicated above.
For the selected alternative, elaborate the behavior, provide more detail in the architecture and further develop the performance requirements that represent the solution. Show how to capture and report the amount of ice needed per day.
Show how plant layout information might be captured, integrated with the other architecture data, and reported to stakeholders.
Capture all interfaces and manage them. Communicate interface information to the appropriate stakeholders.
With the information collected thus far (and add additional information as you see fit), update the requirements and produce specifications for what is needed to support your solution.
Perform Systems Analysis: Over a period of time, conditions will change, roadways will become passable and electricity will be returned sporadically.
Calculate the cost to supply and store the ice. Include the cost for water, fuel, and maintenance of generators, ice machine rentals or purchase, generator rentals or purchase and anything else you feel should be included. Show how the cost estimate is consistent with the design and planning information.
Show a system dynamic analysis for the generate ice stimuli behavior response. For generation of ice, how much water and fuel is consumed to sustain 3000 people for a total of 20 days. What is the maximum number of ice machines that will be required? Calculate the storage size requirement, calculate the water flow rate requirement, calculate the power requirement for the generator, and calculate the footprint requirement. Calculate ice availability based on a rate of consumption of 2lbs of ice/person/day. What is the max amount of ice that can be supplied and any given point in time? What is the amount of ice that will need to be made and how much ice will need to be stored? What is the surge capacity of the provide ice solution?
