Civil Defense Command & Control System
A computerized system can manage the process of receiving calls and move the appropriate units to respond and take necessary measures to address any emergency situation. The system works with information system integration of digital maps and GPS units using the satellite. The system is a bridge linking all parties and relevant agencies to deal accidents and various events in the Kingdom.
The employee receive calls at command and control center, and the system automatically locate the caller on the map, then the employee enter the information in the report template on the system, and the employee identifies the mechanisms to resolve the problem, and then the system processes the information, and on the basis of which determines the nearest available center and available requirements, and sends the report to them, and the system facilitate the employee to follow up the incident and response.
We expect after the completion of this project that we have a system that strengthens the possibilities of civil defense will help to manage the receipt of reports better and faster than before, and the request could be sent for supplies and follow-up will be done automatically by the system.
We visited the Civil Defense in Riyadh and we found that:
They have a system to receive calls and to determine their location by a maps system (GPS) then the officer will move the appropriate units (according to experienced employee) by wireless.
But this system has many problems:
A description of the Actor in this system:
A sequence diagram in Unified Modeling Language (UML) is a kind of interaction diagram that shows how processes operate with one another and in what order. It is a construct of a Message Sequence Chart.
Sequence diagrams are sometimes called event diagrams, event scenarios, and timing diagrams.
A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. This allows the specification of simple runtime scenarios in a graphical manner.
Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. In the Unified Modeling Language, activity diagrams can be used to describe the business and operational step-by-step workflows of components in a system. An activity diagram shows the overall flow of control.
Data models are tools used in analysis to describe the data requirements and assumptions in the system from a top-down perspective. They also set the stage for the design of databases later on in the SDLC.There is three basic elements in ER models:
• Entities are the "things" about which we seek information.
• Attributes are the data we collect about the entities.
• Relationships provide the structure needed to draw information from multiple entities.
A database schema is described in a formal language supported by the database management system (DBMS). In a relational database, the schema defines the tables, the fields in each table, and the relationships between fields and tables.
Schemas are generally stored in a data dictionary. Although a schema is defined in text database language, the term is often used to refer to a graphical depiction of the database structure. (Mutara)
Global Overview:
In every city there is a major center of civil defense (C2) to receive all calls, and this center will manage the units under him (CDC), and also is connected to calls system.
We need to connect these parts a safe and reliable and integrity network and we will do so through a private network.
In our project we do a senior design and development software project that was give the chance to us to apply the knowledge and acquired in the curriculum on a real project of appropriate complexity within a team under realistic constraints. The outcome of our project significant software system, employing knowledge gained from courses throughout the curriculum. The project covers most phases of the software lifecycle. In this part of the project, the focus was on software process and development methodologies, requirements analysis & specification, high-level design, as well as on management of the project. We use software case tools to realize our work.
OBJECTIVES:
To have a fast system
To provide services automatically.
To speed up the response time of civil incidents.
To enhance quality of communication and services.
To document incidental information for later retrieval.
To sends and receives reports and follow-up summery automatically.
Civil defense command & control system is a program that is installed on the computer systems of command and control center for civil defense, and also to be installed at the centers of civil defense.
