Assignment 3 Component Interface For An Emergency Control Roomdue Wee

Design the Requires and the Provides interfaces of at least two (2) components that might be used in a system in an emergency control room for a call-logging component that records calls made.

Design the interfaces of at least two (2) components that might be used in a system in an emergency control room for a vehicle discovery component that, given a post code (zip code) and an incident type, finds the nearest suitable vehicle to be dispatched to the incident.

Include both the Requires interface and the Provides interface in your design.

Develop a visual rendering depicting your design through the use of Microsoft Visio or its open source alternative, Dia. Note: The graphically depicted solution is not included in the required page length. Your assignment must follow these formatting requirements:

  • Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
  • Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
  • Include charts or diagrams created in Visio or an equivalent such as Dia. The completed diagrams / charts must be imported into the Word document before the paper is submitted.

Paper For Above instruction

The modern emergency control room is a critical hub of communication and operational coordination, especially within hospital settings and emergency services. As an essential part of these systems, call-logging components and vehicle discovery systems play vital roles in ensuring swift response, accurate record-keeping, and efficient resource deployment. Designing well-structured component interfaces using a component-based software engineering approach enhances system reusability, maintainability, and scalability. This paper presents a detailed design of the interfaces for two key components: a call-logging system and a vehicle discovery system, including their Requires and Provides interfaces, complemented by a visual architecture diagram.

Design of Call-Logging Component Interfaces

Call-logging is fundamental in emergency response, enabling accurate documentation of VOIP calls, tracking call details, and supporting subsequent analysis for quality and legal purposes. The call-logging component interacts with several other modules such as telephony systems, user interfaces, and storage systems. Its interfaces are designed to facilitate clear communication and data exchange among these components.

Requires Interface for Call-Logging Component

  • Telephony System: Provides real-time call data including call start/end times, caller ID, call duration, and call quality metrics.
  • Storage Service: Ensures persistent storage of call logs, including raw call data and metadata.
  • User Interface Module: Receives commands to initiate or query logs, and displays call records for operators or emergency personnel.

Provides Interface for Call-Logging Component

  • Call Log Data: Offers access to stored call records with methods such as getCallRecord(callID), getCallsByTimeRange(startTime, endTime), and getCallsByCaller(callerID).
  • Status Notifications: Sends status updates such as call logs saved successfully, errors, or system alerts to other modules or UI components.
  • Event Listeners: Supports subscription to call logging events for real-time updates or audit purposes.

Design of Vehicle Discovery Component Interfaces

The vehicle discovery system aims to enhance emergency response efficiency by accurately finding and dispatching the nearest suitable vehicle based on incident location and type. This involves integration with GPS data, incident reports, and fleet management modules. The design of this component incorporates interfaces to query vehicle locations and to dispatch vehicles accordingly.

Requires Interface for Vehicle Discovery

  • GPS Location Service: Provides real-time geographic coordinates of all available vehicles.
  • Incident Data Service: Supplies incident details, including postal code, incident type, and priority.

Provides Interface for Vehicle Discovery

  • Nearest Vehicle Finder: Supplies methods such as findNearestVehicle(postCode, incidentType), which returns a vehicle ID or object with location details.
  • Dispatch Notification: Notifies fleet management or emergency dispatch modules about the selected vehicle for assignment.
  • Monitoring and Updates: Provides status updates on vehicle availability, ongoing dispatches, and estimated arrival times.

Visual Representation of the System Architecture

The diagram created in Visio (or Dia) illustrates the interaction between the components. The call-logging component interacts with the telephony system, storage service, and user interface. Simultaneously, the vehicle discovery component interfaces with GPS location and incident data services, providing outputs to the dispatch system. The diagram highlights the flow of data, the separation of required and provided interfaces, and the modular architecture enabling scalability and maintainability.

In conclusion, designing clear, well-structured interfaces for these emergency management components enhances system interoperability, reusability, and efficiency. Proper implementation of these interfaces ensures the emergency control room can effectively track communications and rapidly deploy resources, ultimately improving patient outcomes and operational responsiveness.
