Part 1:

A system is needed to assist people with severe disabilities to live a relatively comfortable life. For this assignment you may assume that the patients reside in their own premises with a carer available to look after them. However the carer is often doing other household duties and may not be in the same room as the patient. The patients also have expressed the desire to be as independent as possible. You may assume that the patients have no movement from their neck down. You may also assume that the patient can freely move their heads and eyes, and can speak, though sometimes very softly. Patient surveys indicate that they would like to have the ability to:

• Adjust the bed height and the inclination of the backrest.
• Summon the carer (without having to shout).
• Be monitored for vital medical signs if needed and to alert the carer if there is any danger (the system monitoring the vital signs already exists and is being supplied independently of your system).
• Adjust the room's environment (temperature, light levels, opening and closing
• of window curtains).
• Turn the entertainment system on or off, and to adjust volume levels, channels, and the like. The entertainment system consists of a Television, a DVD player, a music system including CD, mp3 and Radio.
• Make, and respond to, phone calls.
• Receive, read, compose and send emails

You are required to provide a functional hierarchy diagram of this system developed to at least 4 levels (level 1 being the top level, and level 4 being the lowest), a functional flow block diagram showing the flow through at least one aspect of the system's functionality, and an N2 Chart You may make reasonable assumptions regarding the requirements that the owners may have for these systems. Based upon your functional analysis, postulate some high-level system requirements for the system. Demonstrate that your

requirements are "good" requirements by applying the parsing and the primitive requirements analysis techniques on at least three of your requirements.

Part Two - Model Based Systems Engineering.

Research the topic: System of Systems (SoS). You must use scholarly Journals and authoritative literature for this. Wikipedia and similar sources will not be sufficient for this. From your research identify the following:

• The key concepts of SOS.
• How did they evolve? What prompted such evolution?
• What are the key current issues (if any) and discussions concerning systems engineers and managers regarding SOS?
Present your findings as follows:
• Produce a power-point presentation suitable for a 20-minute talk on SOS, meant to "educate" people unfamiliar with them. You are to produce a maximum of 8 power-point charts, with no more than 5 bullet points on each. You may use diagrams if these get your message across more clearly. (Note: you will NOT be required to give this presentation).
• Produce "speaker notes" to accompany your charts - no more than 5 bullet points per chart. These speaker notes should be in the notes section of your charts (use the PowerPoint notes view to see this). The speaker notes should be your group's own work, and not "cut and paste" from other sources.
• Provide references to your information sources.
