Construction Phase of RUP

Construction Phase 1 Not user friendly In-efficient use of space Feedbacks from peers

Construction Phase 2 Streamline user input Clearer instructions Reset/Save feature Partitioning

Construction Phase 3 (Final) Customizable Inputs 3 Step Simulation Approach Print feature Clearly defined Partitioning 1 Step installation process

Testing Test after each milestone (new version) Create test cases Analyze result Rectify result Repeat

Interface / Process Flows

Lift Algorithms Nearest Car (NC) Fixed Sectoring Common Sector System (FSO) Fixed Sectoring Priority Timed System (FS4) Dynamic Sectoring System (DS)

Nearest Car (NC) Lift serve passengers with the highest FS If call is in the same direction as lift ▫FS = (N+2) – d If call is in the different direction as lift ▫FS = (N+1) – d If lift is moving away from call ▫FS = 1 where n = (number of floors – 1) d = distance between lifts and call

Fixed Sectoring Common Sector System (FSO) 10 floors with 2 lifts Lift 1 serve floor 1 to 5 Lift 2 serve floor 6 to 10 and floor 1

Fixed Sectoring Priority Timed System (FS4) 10 floors with 2 lifts Lift 1 serve floor 1 to 5 Lift 2 serve floor 6 to 10 and floor 1 With priority ▫Priority increases proportionally to waiting time

Dynamic Sectoring System (DS) 10 floors with 2 lifts Sector = 5 Lift 1 and 2 will serve its current floor and +- 2

Features Runs almost instantaneously! Generate traffic flow according to time Suggest the best algorithm for the building and traffic model View the average user wait time and average user travel time Allows you to get an overview of the lift idle time ▫Calculate power consumption

System Requirements Requirements Operating System Windows XP SP3, Windows Vista Windows 7, Windows 8, Windows 8.1 and Mac OS X 10.8 and above CPU2 GHz Intel Core 2 Duo or above Memory 1 GB or more Hard drive100 MB of free space Internet Connection None

Learning Points Tight deadline ▫Not meeting a deadline causes delay to certain expectation Adapt to new IDE ▫New software takes time to learn Minutes taking ▫Keeping track of our activity Discipline ▫Keeping track of own progress on blogs
