Program: Lecture by Tom Montague, AMSI

Topic:: AMSI Industry Internships

The AMSI industry internship program is now in its forth year of operation. This presentation will cover the goals, history recent developments of the program and provide examples of the interesting problems addressed by interns, academic mentors and their industry partners. It will also include an overview as to how to take advantage of this opportunity.

After working as a biologist at Monash University on seabird ecology Tom completed his D.Phil in the Wildlife Conservation research Unit at Oxford University in 1993. He then worked as an ecologist for Landcare Research in New Zealand before returning to Australia and taking up a position as a science advisor to the Victorian government in 2002. It was around this time he realized how much industry and Australians need to improve their understanding of mathematical sciences if we were to build our industrial capability. His current job as industry marketing manager at AMSI is all about building the capabilities of business, industry and government and AMSI.

Program: Lecture by Philip Kilby - NICTA and ANU

Topic:: The trade-off between flexibility, solution quality and execution cost in Vehicle Routing Problems

The Vehicle Routing Problem considers the delivery of goods to a set of customers using multiple vehicles. The aim is to deliver (or pickup, or pickup and deliver) the goods as efficiently as possible.

In the real world, the routes are always constrained. In the OR literature, some of these constraints have been examined (capacity, time windows, etc). However, the diversity of constraints seen in the real world is truly staggering - vehicles can't fit under eaves, complex 2D and 3D loading constraints, complex work/rest rules, connections to ferry timetables, and (my favourite) the "affairs" constraint that limits which customers a driver can visit depending on whether he is currently having, or has had in the past, an affair with staff at the customer (apparently updated weekly).

In this paper we outline an architecture for solving instances of the Vehicle Routing Problem that have arbitrary constraints that must be observed by solutions. The system uses a Constraint Programming (CP) system to model, propagate and check constraints. The use of the CP system allows the approach to be very flexible -- producing solutions for essentially arbitrary constraints that model the business practices of the companies that will use the the system. However, this flexibility comes at the price of increased execution time, and may affect solution quality. The aim of the paper is to look at some facets of the trade-off between flexibility, solution quality and execution cost.

Bio: Philip Kilby is Principal Researcher with NICTA, and an Adjunct at ANU. He has worked with transport-related problems in academia and with industry for more than 20 years.

Program: Lecture by Simon Dunstall - CSIRO

Topic:: Developing a Transport Infrastructure Planning System

Reporting on joint work with Kim Levy, Andreas Ernst, Gaurav Singh, Stuart Woodman, Andrew Higgins, Leorey Marquez, Olena Gavriliouk and Dhananjay Thiruvady.

Mineral freight volume increases are driving transport infrastructure investments on Australia's east and west coasts. New and upgraded railways, roads and ports are planned or are under construction -- to serve new mines, processing facilities and international markets. One of the fastest growing regions is Northern Queensland, central to which is the so-called Northern Economic Triangle that has Rockhampton, Mt Isa and Townsville at its vertices. CSIRO has been working with Queensland Government to construct a new GIS-based infrastructure planning optimisation system that is known as the Infrastructure Futures Analysis Platform (IFAP). IFAP can be used to build long-term (eg. 25 year) plans for infrastructure development in regions such as the Northern Economic Triangle. IFAP consists of a commercial Geographic Information System (MapInfo), a database and a network optimisation solver that has been constructed by CSIRO and will ultimately by open-sourced. The prototype IFAP is nearing completion and in this presentation I will discuss the development process and the underlying network optimisation problem.

Program: Lecture by Geoff Prince, AMSI

Topic:: New Directions at AMSI

Professor Geoff Prince will give a brief overview of AMSI's philosophy and operations followed by an in depth presentation on our new internship scheme and the recent changes to our scientific program. Questions and discussion are welcome.

Professor Geoff Prince is director of the Australian Mathematical Sciences Institute. He has spent most of his research and teaching career at La Trobe University but he has been involved with AMSI since 2004. His mathematical interests lie in differential geometry and differential equations.

Topic:: Resource Allocation in a Tactical Arms Race with Temporary Advantages

We consider an arms race between two opponents (e.g., government forces vs. insurgents) where each advantage that is achieved by one of the opponents is limited in time and expires when the other opponent develops a new weapon or counter-measure (in contrast with the "winner-takes-all" situation that characterizes much of the literature on investments in competitive business environments). We first consider a variety of models that apply to a one-sided situation, where the defender has to determine how much to invest in developing counter-measures to a weapon employed by the attacker. The decision problems are expressed as (convex) nonlinear optimization problems. We present an example that provides some operational insights regarding optimal resource allocation. We also consider a two-sided situation and develop a Nash equilibrium solution that sets investment values so that both parties have no incentive to change.

Topic:: Fast Approaches to Robust Railway Timetabling

The Train Timetabling Problem (TTP) consists in finding a train schedule on a railway network that satisfies some operational constraints and maximizes some profit function which counts for the efficiency of the infrastructure usage. In practical cases, however, the maximization of the objective function is not enough and one calls for a robust solution that is capable of absorbing as much as possible delays/disturbances on the network. In this paper we propose and analyze computationally four different methods to find robust TTP solutions for the aperiodic (non cyclic) case, that combine Mixed Integer Programming (MIP) and ad-hoc Stochastic Programming/Robust Optimization techniques. We compare computationally the effectiveness and practical applicability of the four techniques under investigation on real-world test cases from the Italian railway company (Trenitalia). The outcome is that two of the proposed techniques are very fast and provide robust solutions of comparable quality with respect to the standard (but very time consuming) Stochastic Programming approach.
