Using Cognition Cockpit Version 5.3(A Web 2.0 Application)

(As presented by Cognition as part of a Systems Engineering challenge for a simulated total system)

“NotilHotel Parking System”


™

1. General Background

NotilHotels is a world-wide hotel chain with head-offices in Paris, specializing in low-cost, high valued business hotels in city centers around the world. Each hotel has some space for parking, but the space is often occupied by people working in nearby offices, causing arriving guests not to find space for parking their car near the hotel. In order to secure parking space for their guests, they plan to develop an automated parking system that can regulate the use of the limited parking space.

INCOSE Challenge Problem Statement


™

2. The requirements specified by the management are:

-One or two parking lots per hotel

-Optimum service to hotel guests

-User-friendly, minimum hassle operation

-Payment of a reasonable parking fee included in the hotel bill, or payable separately

-Easily adaptable to the local environment, because there are hotels in 50 different countries

-In case there is more space than expected guests on a given day, the remaining parking space is to be made available to non-guests, in order to maximize revenues

- The system must be operational at the opening of their newest hotel January 25, XXXX



™

3. Vendors are asked to provide the following:

-Compose the system specification

-Demonstrate requirements handling

-Define the system in its environment

-Define logical sub-systems, flows from sub-systems to the environment and flows between sub-systems

-Define sub-system activities

-Don’t forget to include the particularities of the human sub-systems (=humans) that are part of the total system

-Describe the functional modes of the system and transfers between them

-Draw a timeline for the development of the system

- Show how your tool supports the System Engineering activities



™

4. Questions to the Customer

From Thursday June 12th, participants may send “questions to the customer” ([email protected]). We (the customer) will do our best to answer these questions to all contact persons about once a day. However, the customer may have to think for some time about some questions and may have no good answer to some questions. Just a typical customer.

At the symposium, the Challenge and the questions (if any) will be posted on the designated Tool Vendor Challenge notice board. Questions may be submitted until Monday (June XX) 17:30. Questions should state the organization asking the question. All challenge participants and (at the Symposium) all conference attendees will be able to see all the questions and the answers.

Transfer Functions are Required for Predictive Engineering

Calculate nominal output value given a set of inputs

y = f(x1, x2, … xn)

or

Y = f( x, y, n)

Where: x = input specs, y = subordinate results, n = noise
