Concept Analysis : Concept Exploration Phase

969 Words Jul 5th, 2015 4 Pages

The main objective of the concept exploration phase is to convert the operationally-oriented system view into an engineering-oriented view. The term “visualize” is meant to connote the conceptualization of the general functions and physical embodiment of the subject in the case of needs analysis at the subsystem level. Below is a figure from our Unit 9 Course Materials document depicting the place of the concept exploration phase in the overall system development process.

Water Treatment and Supply System Functions

Below I have identified the functions that the alternate water treatment and supply system will need to perform. These are minimal and high level functions of the system.

Input Functions

1. Accept user command (on/off)
2. Receive water for treatment
3. Distribute electricity
4. Distribute water through the treatment plant

Transformative Functions

1. Filter water (pre-treatment)
2. Treat Water (physical and/or chemical treatment)
3. Chlorinate water (final treatment)

Output Functions

1. Provide status
2. Facilitate removal of treatment waste materials
3. Store and supply water to stakeholders
System Context Diagram

The context diagram is an important tool for a systems engineer. It shows the external entities and their interactions with the system. Below is a context diagram for an alternate water supply system.
