Optimising Income Drawdown in the Dual Space
Emms, Paul - 2020
One attractive objective for a pensioner using the income drawdown option is to minimise the deviation of the pension fund from a prescribed deterministic target. Typically, this problem is formulated as a linear-quadratic optimal control problem, which has the shortcoming that over-performance...

Stochastic Optimization Applied to Self-Financing Portfolio : Does Bequest Matter?
Gazioglu, Saziye - 2011
assume a constant consumption-wealth ratio that constrains the boundary conditions, hence influencing the coefficient of the … risk premium. The main contribution of our paper is that we drop the assumption of a constant consumption-wealth ratio. We … terminal condition of wealth with and without bequests. We also simulate the stochastic optimization with a self …

Optimal Batch Ordering Over a Finite Planning Horizon
Alsuwainea, Abdullah O. - 2020
This paper is concerned with finding an optimal inventory policy for a finite horizon, two-stage inventory model. In this model, products may be manufactured in two stages. The first stage uses raw material from an external supplier and the second stage uses raw material from defective items...

Computation of Approximate Optimal Policies in a Partially Observed Inventory Model With Rain Checks
Bensoussan, Alain - 2020
This paper proposes a new methodology to solve partially observed inventory problems. Generally, these problems have infinite dimensional states that are conditional distribution of the inventory level. Our methodology involves linearizing the state transitions via unnormalized probabilities. It...

A Dynamic Lot Sizing Model with Learning in Setups
Chand, Suresh; Sethi, Suresh - 2017
This paper considers the dynamic lot sizing problem of H. M. Wagner and T. M. Whitin with the assumption that the total cost of n setups is a concave nondecreasing function of n. Such setup costs could arise from the worker learning in setups and/or technological improvements in setup methods....

Global Optimization of Some Difficult Benchmark Functions by Cuckoo-Host Co-Evolution Meta-Heuristics
Mishra, Sudhanshu K. - 2012
This paper proposes a novel method of global optimization based on cuckoo-host co-evaluation. It also develops a Fortran-77 code for the algorithm. The algorithm has been tested on 96 benchmark functions (of which the results of 30 relatively harder problems have been reported). The proposed...

Exploiting Fitness Distance Correlation of Set Covering Problems
Finger, Markus; Stutzle, Thomas; Ramalhinho Dias … - 2002
The set covering problem is an NP-hard combinatorial optimization problem that arises in applications ranging from crew scheduling in airlines to driver scheduling in public mass transport. In this paper we analyze search space characteristics of a widely used set of benchmark instances through...

Large-Scale Mean-Variance Optimization and Chunking Algorithm
Koumou, Gilles Boevi - 2022
We propose a new, highly effective and easy-to-implement algorithm for solving large-scale mean-variance optimization problems --- with weight upper bound constraints and without short sales --- when the size of mean-variance portfolios is much smaller than the number of assets, which is almost...

Solving discrete systems of nonlinear equations
Laan, Gerard van der; Talman, Dolf; Yang, Zaifu - 2009
We study the existence problem of a zero point of a function defined on a finite set of elements of the integer lattice of the n-dimensional Euclidean space. It is assumed that the set is integrally convex, which implies that the convex hull of the set can be subdivided in simplices such that...
