The United States Coast Guard (USCG) is world’s premier search and rescue, law enforcement and counter-drug organization.

The Coast Guard needs the means to identify optimal assignment of its aircraft

Modeling capabilities:- Analyze response and mission demand- Provide decision makers with alternative

aircraft assignments optimized to operational and logistic capability and expected mission needs

Determine parameters CG data Clean data

Interface to input simulation parameters

Simulation Clean data SAR Events Maintenance events Aircraft use and availability

Graphical output of model

Better way of examining and cleaning large amounts of data

Provide Graphical User Interface for user interaction

Scheduled missions(training) Scheduled maintenance Unscheduled missions(search &

rescue) Unscheduled maintenance(aircraft

malfunctions)

Random events- Interarrival time of unscheduled missions- Length of unscheduled missions- Interarrival time of unscheduled

maintenance- Length of unscheduled maintenance

USCG has provided a very large data set

Problems- Some data not needed- Inconsistencies in the data- Missing data- Manual cleaning is inefficient - Problems with manually entered data sets

MatLab HTML5 Python

› SimPy

MATLAB is a numerical computing environment. It allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, and Java.

Current simulation coded in Matlab

HTML 5 is a markup language for structuring and presenting content for the web. It is the fifth revision of the HTML standard.- Can create apps such as desktop applications,

which allows the web platform to be used to reach all users at once

- Can create apps that function even when the system is offline

- Wide variety of graphic elements, such as animation

Python is currently one of the most popular programming languages. Although it is often viewed as a "scripting" language, it is a general purpose programming language. It is used for GUI and database programming, client- and server-side web programming, and application testing.

SimPy - (Simulation in Python) is a discrete-event simulation language for Python.

Easy to read Easily extended by adding new modules

implemented in a compiled language such as C or C++

Runs on many different operating systems Easy to maintain GUI Programming: Python supports GUI

applications that can be created and ported to many system calls, libraries, and windows systems, such as Windows MFC, Macintosh, and the X Window system of Unix.
