INTRODUCTION
Introduction (1)
Program Studi Teknik Industri ITB
• VIP-PLANOPT (Visually Interfaced
Package of floor-PLAN layout
OPTimization)
What?
• 20-50% of operating cost relates to material handling
• US business spend about trillion dollar on new facilities
Motivation
(Productivity and
profitability)

Introduction (2)
Program Studi Teknik Industri ITB
• Guaranteed superiority on other algorithm for low-cost layout
• Has a record of UNBEATEN PERFORMANCE with a money back guarantee
Filling the Gap
• User-specified pick-up and drop-off points
• Allow any number facilities to be “anchored”
• Specify the shape and the size
• Module Padding
• Forbidden Area Module
• No-Flow Modules
Unmatched Functonality

Introduction (3)
Program Studi Teknik Industri ITB
• Better than all GA’s, SA’s and the conventional analytical or heuristic techniques
• Has not been published
• Introduced double precision arithmetic
• Introduce new techniques to reduce dependence the user-specified
• Introduction Penalty functions using boundary shape

Conclusion
1
• VIP-PLANOPT has been proved that could give better solution in many problems compared with any other approach.
2
• But, VIP-PLANOPT give worse solution in PTLP case. That is because the lack of experience in using this powerful software.
3
• Also user must define the PTLP case more detail when using the software. It is because VIP-PLANOPT provides more parameter which is very relevant with the real system.
