Final answer:
To create a context diagram and Data Flow Diagrams using Visio for training logistics, analyze the problem, use concept combination tables for design ideas, identify the system and energy flows, develop problem statements, and organize work using graphic organizers.
Step-by-step explanation:
To develop a context diagram and nested Data Flow Diagrams (DFD) using Visio, you'll need to follow these guidelines based on the problem specifications provided in your textbook:
Understanding the Problem
Analyze the problem by understanding the training logistics information that is given in the textbook. A time-line may be helpful for outlining the sequence of events or processes.
Creating Diagrams
Context Diagrams are high-level diagrams that show the system as a single process with its relation to external entities. For nested DFDs, you'll break down the main process into sub-processes showing detailed data flow within the system.
Design Concepts
Use a concept combination table from solutions to subproblems to generate different design concepts. Sketch the designs for each concept, as represented in your textbook.
Identifying System and Energy Flow
Identify your system of interest and draw a diagram to show energy flow. Determine what needs to be solved and list the unknowns.
Developing Problem Statements
Develop a problem statement based on your understanding of the issues, such as those associated with commuting. Use this statement to identify criteria and constraints for the system design.
Organizing Your Work
A graphic organizer like a table can be very useful in keeping your work structured. This can be revised later as you refine your draft.
