Zero-sum Markov games with impulse controls
(Society for Industrial and Applied Mathematics, 2020)In this paper we consider a zero-sum Markov stopping game on a general state space with impulse strategies and infinite time horizon discounted payoff where the state dynamics is a weak Feller--Markov process. One of the ... -
Comments on the 'polynomial formulation and heuristic-based approach for the k-travelling repairman problem'
(Inderscience Enterprises Ltd., 2019)The paper 'polynomial formulation and heuristic-based approach for the k-travelling repairman problem' claims to present the first polynomial formulation for the k-travelling repairman problem (k-TRP). We first make some ... -
Modeling economic activities and random catastrophic failures of financial networks via gibbs random fields
(Springer, 2020)The complicated economic behavior of entities in a population can be modeled as a Gibbs random field (GRF). Even with simple GRF models, which restrict direct statistical interactions with a small number of neighbors of ... -
New-product diffusion in closed-loop supply chains
(INFORMS, 2020)Problem definition: We study the sales planning problem of a producer who sells new and remanufactured versions of a durable good over a finite life cycle. We investigate whether slowing down product diffusion by choosing ... -
Certainty equivalent and utility indifference pricing for incomplete preferences via convex vector optimization
(Springer Science and Business Media Deutschland GmbH, 2020)For incomplete preference relations that are represented by multiple priors and/or multiple—possibly multivariate—utility functions, we define a certainty equivalent as well as the utility indifference price bounds as ... -
Sparse solutions to an underdetermined system of linear equations via penalized Huber loss
(Springer, 2020)We investigate the computation of a sparse solution to an underdetermined system of linear equations using the Huber loss function as a proxy for the 1-norm and a quadratic error term à la Lasso. The approach is termed ... -
On guarding real terrains: the terrain guarding and the blocking path problems
(Elsevier, 2020)Locating a minimum number of guards on a terrain such that every point on the terrain is guarded by at least one of the guards is known as the Terrain Guarding Problem (TGP). In this paper, a realistic example of the terrain ... -
The effect of economies-of-scale on the performance of lot-sizing heuristics in rolling horizon basis
(Taylor and Francis, 2021)In this article, we consider the production planning problem in the presence of (dis)economies-of-scale in production costs on a rolling horizon basis with a fixed forecast horizon. We propose variants of three well-known ... -
A stochastic framework to evaluate the impact of agricultural load flexibility on the sizing of renewable energy systems
(Elsevier, 2020)Pumping of water for agriculture can be a flexible component of electric demand. In this study, a framework that involves scenario based stochastic programming models is developed to examine the effect of load shifting on ... -
Structural results for average‐cost inventory models with Markov‐modulated demand and partial information
(Wiley-Blackwell, 2020)We consider a discrete‐time infinite‐horizon inventory system with non‐stationary demand, full backlogging, and deterministic replenishment lead time. Demand arrives according to a probability distribution conditional on ... -
4-generated pseudo symmetric monomial curves with not Cohen–Macaulay tangent cones
(TUBITAK, 2020)In this article, standard bases of some toric ideals associated to 4-generated pseudo symmetric semigroups with not Cohen-Macaulay tangent cones at the origin are computed. As the tangent cones are not Cohen-Macaulay, ... -
Balance in resource allocation problems: a changing reference approach
(Springer, 2020)Fairness is one of the primary concerns in resource allocation problems, especially in settings which are associated with public welfare. Using a total benefit-maximizing approach may not be applicable while distributing ... -
Lower cone distribution functions and set-valued quantiles form galois connections
(SIAM, 2020)It is shown that a recently introduced lower cone distribution function, together with the set-valued multivariate quantile, generates a Galois connection between a complete lattice of closed convex sets and the interval ... -
OM forum: innovative online platforms: research opportunities
(INFORMS: Institute for Operations Research and the Management Sciences, 2020)Economic growth in many countries is increasingly driven by successful startups that operate as online platforms. These success stories have motivated us to define and classify various online platforms according to their ... -
Safety stock placement for serial systems under supply process uncertainty
(Springer, 2020)In this study, we address safety stock positioning when demand per period is a known constant but supply is uncertain. The supply is either available or not available, while the setting is that of a periodically reviewed, ... -
Codon optimization: A mathematical programing approach
(Oxford University Press, 2020-04)Motivation: Synthesizing proteins in heterologous hosts is an important tool in biotechnology. However, the genetic code is degenerate and the codon usage is biased in many organisms. Synonymous codon changes that are ... -
A thermo-mechanical model of drill margin-borehole surface interface contact conditions in dry drilling of thick CFRP laminates
(Elsevier, 2020)Dry drilling of thick carbon fiber reinforced polymer (CFRP) laminates requires careful selection of process parameters in order to obtain acceptable borehole surface quality. Complex contact conditions between the drill ... -
Multi-stage stochastic programming for demand response optimization
(Elsevier, 2020-02-19)The increase in the energy consumption puts pressure on natural resources and environment and results in a rise in the price of energy. This motivates residents to schedule their energy consumption through demand response ... -
Codon optimization by 0-1 linear programming
(Elsevier, 2020-02)The problem of choosing an optimal codon sequence arises when synthetic protein-coding genes are added to cloning vectors for expression within a non-native host organism: to maximize yield, the chosen codons should have ... -
Competitive location and pricing on a line with metric transportation costs
(Elsevier, 2020-04-01)Consider a three-level non-capacitated location/pricing problem: a firm first decides which facilities to open, out of a finite set of candidate sites, and sets service prices with the aim of revenue maximization; then a ...
