OPTIMIZING CLASSIFICATION TRACKS ALLOCATION BETWEEN YARDMEN

Track Allocation in Freight-Train Classification with Mixed Tracks

We consider the process of forming outbound trains from cars of inbound trains at rail-freight hump yards. Given the arrival and departure times as well as the composition of the trains, we study the problem of allocating classification tracks to outbound trains such that every outbound train can be built on a separate classification track. We observe that the core problem can be formulated as ...

Optimizing Dynamic Resource Allocation

We present a formulation, solution method, and program acceleration techniques for two dynamic control scenarios, both with the common goal of optimizing resource allocations. These approaches allocate resources in a non-myopic way, accounting for long-term impacts of current control decisions via nominal belief-state optimization (NBO). In both scenarios, the solution techniques are paralleliz...

Optimizing Budget Allocation in Graphs

In a classical facility location problem we consider a graph G with fixed weights on the edges of G. The goal is then to find an optimal positioning for a set of facilities on the graph with respect to some objective function. We introduce a new framework for facility location problems, where the weights on the graph edges are not fixed, but rather should be assigned. The goal is to find the va...

Optimizing Nonlinear Adaptive Control Allocation

A control-Lyapunov approach is used to develop an adaptive optimizing control allocation algorithm for over-actuated mechanical systems where the actuator model is a¢ ne in the uncertain parameters. Uniform global (asymptotic) stability is guaranteed by the control allocation de…ned by the dynamic update laws in combination with an exponentially stable controller.
