A genetic algorithm for maximum-weighted tree matching problem
Gulek, Mehmet; Toroslu, İsmail Hakkı (Elsevier BV, 2010-09-01)
In hierarchal organizations, for assigning tasks to the divisions of the organization some constraints must be satisfied. This article investigates one such problem in which there are k different tasks to be accomplished and each division's performance on each task may be different and represented by a scalar value. In this article we formally introduce this real life decision problem, named as Maximum-Weighted Tree Matching Problem, and propose a genetic algorithm solution to it, and give some experimental...
Conceptual Association of Functional Size Measurement Methods
Demirörs, Onur; Gencel, Cigdem (Institute of Electrical and Electronics Engineers (IEEE), 2009-05-01)
Functional size determines how much functionality software provides by measuring the aggregate amount of its cohesive execution sequences. Alan Albrecht first introduced the concept in 1979. Since he originally described the function point analysis (FPA) method, researchers and practitioners have developed variations of functional size metrics and methods. The authors discuss the conceptual similarities and differences between functional size measurement methods and introduce a model for unification.
Shortest path optimization of haul road design in underground mines using an evolutionary algorithm
Yardımcı, Ahmet Güneş; Karpuz, Celal (Elsevier BV, 2019-10-01)
All types of underground mine access serve as permanent openings to transfer men and extracted material throughout the life of an operation. Development and operating costs are predominantly controlled by the haul road length. However, the most common method to design the main haul road is to rely on the empirical knowledge of skilled mine design experts. This is sufficient for simple mine layouts. However, determination of the optimum path without violating navigation constraints in complex underground net...
Model-based code generation for HLA federates
Adak, Mehmet; Topcu, Okan; Oğuztüzün, Mehmet Halit S. (Wiley, 2010-02-01)
This paper addresses the problem of automated code generation for a High Level Architecture compliant federate application given its behavior model. The behavior model is a part of the architectural model of a federation that the federate can participate in. The federate behavior model is based on Live Sequence Charts, adopted as the behavioral specification formalism in the Federation Architecture Metamodel (FAMM). FAMM serves as a formal language for describing federation architectures. An objective is to...
The static stochastic knapsack problem with normally distributed item sizes
Merzifonluoglu, Yasemin; Geunes, Joseph; Romeijn, H. Edwin (Springer Science and Business Media LLC, 2012-09-01)
This paper develops exact and heuristic algorithms for a stochastic knapsack problem where items with random sizes may be assigned to a knapsack. An item's value is given by the realization of the product of a random unit revenue and the random item size. When the realization of the sum of selected item sizes exceeds the knapsack capacity, a penalty cost is incurred for each unit of overflow, while our model allows for a salvage value for each unit of capacity that remains unused. We seek to maximize the ex...
