A stochastic optimization model for designing last Mile relief networks
In this study, we introduce a distribution network design problem that determines the locations and capacities of the relief distribution points in the last mile network, while considering demand- and network-related ...
Application of sequence-dependent traveling salesman problem in printed circuit board assembly
Optimization issues regarding the automated assembly of printed circuit boards attracted the interest of researchers for several decades. This is because even small gains in assembly time result in very important benefits ...
League scheduling and game bundling in sports industry
Most sport clubs offer season tickets first and they allow purchasing single tickets at a later date. There are several decision problems within this context; the determination of the optimal time at which the switch from ...
Formulations and branch-and-cut algorithms for the generalized vehicle routing problem
The generalized vehicle routing problem (GVRP) consists of finding a set of routes for a number of capacitated vehicles on a graph where the vertices are partitioned into clusters with given demands, such that the total ...
Combining and solving sequence dependent traveling salesman and quadratic assignment problems in PCB assembly
In this study we undertake the optimization of chip shooter component placement machines which became popular in assembling printed circuit boards (PCB) in recent years. A PCB is usually a rectangular plastic board on which ...
Pricing decisions in a strategic single retailer/dual suppliers setting under order size constraints
(Informa Group, 2016)
In this paper, we study a duopolistic market of suppliers competing for the business of a retailer. The retailer sets the order cycle and quantities from each supplier to minimize its annual costs. Different from other ...
Solving a large-scale crew pairing problem
(Palgrave Macmillan, 2015)
Airline companies seek to solve the problem of determining an assignment of crews to a pre-determined flight schedule with minimum total cost, called the Crew Pairing Problem (CPP). Most of the existing studies focus on ...
Rounding heuristics for multiple product dynamic lot-sizing in the presence of queueing behavior
We present heuristics for solving a difficult nonlinear integer programming (NIP) model arising from a multi-item single machine dynamic lot-sizing problem. The heuristic obtains a local optimum for the continuous relaxation ...
A profit-driven Artificial Neural Network (ANN) with applications to fraud detection and direct marketing
The rapid growth in data capture and computational power has led to an increasing focus on data-driven research. So far, most of the research is focused on predictive modeling using statistical optimization, while profit ...
