Part 1: Introduction • • The people Background Literature Review Idea proposal MIV

The people • Instructor: Mr. Huynh Anh Dung • Team members: – Tran Hai Dang – Ta Duc Tung – Duong Hue Linh – Pham Quang Hung – Ha Thi Tham – Nguyen Hai Ha MIV

MIV Background • Vietnam has a large exclusive economic zone (EEZ) with more than 20, 000 far shore fishing boats

MIV Background • Problems – Seasonal typhoons claim over hundred lives every year – Fishermen arrested • Major causes – Fishermen lack of information about the typhoons, their position… – Managers lack of information about the situation of fishermen. There is urgent need to solve those problems.

MIV Literature Review - Coastal Station System Advantages Disadvantages Easy to use Anti-interference In many urgent cases, sailor cannot hear the message clearly, which lead to misunderstanding and damaging

MIV Literature Review - Viettel Coastal and Islands Base Transceiver Station (BTS) System Advantages Can use cell phone Disadvantages Narrow range Cannot cover full range of South – East Asia Sea

MIV Literature Review - Movimar System Advantages Disadvantages High technology High capital investment Guarantees a high quality of Number of monitored vessel communicating and rescuing is only 2850 Technology dependency (depend on France)

MIV Idea proposal • Abstract & Idea – Build a system for informing fishers of weather forecast, storm notification and visualizing this information. – Vessel monitoring, search and rescue Develop an additional method of communicating on HF band. System will transfer data from coastal station to vessels and vice-versa

Idea Proposal MIV • Digital • Visualization Cons Pros • Pros & Cons • Equipment Investment • Training Fishers

Part 2: Project Management Plan • • • Proposed System Development Environment Process Project Organization Project Planning MIV

MIV Proposed System

Development Environment • Hardware – Transceiver : VX 3 R, KENWOOD-TS 2000 – Audio connection line – GPS device MIV

Development Environment • • Visual Studio 2010. NET Framework 4. 0 SQL Server 2008 Express Eclipse Java / Java Swing Framework Google Earth API OS: Windows 7 MIV

Process Iterative & incremental model MIV

MIV Planning • Risk Management – Hardware Availability – Testing – Resource Experience – Project Management Skill – User Involvement

Part 3: Requirement Specification • Users • Use case Diagram • Non-functional requirement MIV

MIV Users User Application Description Central operator Viewer User of Viewer application, responsible for - Monitoring vessel positions, voyages - Create weather messages, storm messages Operator Coastal Station User of Coastal Station application, responsible for - Monitoring messages to be broadcasted to vessels, received from vessels - Broadcasting messages to vessels Fisher On-sea Terminal User of On-sea Terminal application, responsible for monitoring their own vessel position on map, being alerted about storm, weather information

MIV On-sea Terminal – Fisher Use cases

On-sea Terminal – Storm visualization Screen MIV

Coastal Station – Operator Use cases MIV

Viewer – Central Operator Use cases MIV

MIV Viewer – Vessel Monitoring Screen

Non-functional Requirements MIV • Language: Vietnamese • Usability: easy to use, especially for fishers • HF band requires error detection & correction, package losing mechanism
