An indexing technique for similarity-based fuzzy object-oriented data model
Yazıcı, Adnan; Koyuncu, M (2004-01-01)
Fuzzy object-oriented data model is a fuzzy logic-based extension to object-oriented database model, which permits uncertain data to be explicitly represented. One of the proposed fuzzy object-oriented database models based on similarity relations is the FOOD model. Several kinds of fuzziness are dealt with in the FOOD model, including fuzziness between object/class and class/superclass relations. The traditional index structures are inappropriate for the FOOD model for an efficient access to the objects wi...

We have identified a completely integrable family of Monge-Ampère equations through an examination of their Hamiltonian structure. Starting with a variational formulation of the Monge-Ampère equations we have constructed the first Hamiltonian operator through an application of Dirac's theory of constraints. The completely integrable class of Monge-Ampère equations are then obtained by solving the Jacobi identities for a sufficiently general form of the second Hamiltonian operator that is compatible with the...
A genetic algorithm for the location-routing problem with time windows
Özgönenç, Hande; Meral, Fatma Sedef; Department of Industrial Engineering (2006)
The emphasis on minimizing the logistics costs to decrease overall system costs has led the researchers to consider the interdependencies between the decisions of locating facilities and planning the routes from those facilities. The location-routing problems considering this issue are the subject of this thesis study. A two-level hierarchical distribution system is considered in which goods are delivered from the sources (plants) to the facilities (depots) and then from the facilities to the customers. The...

The elasticity of the follower train and return spring dynamics are incorporated in a general nondimensional analysis for follower jump in force-closed cam mechanisms. The follower train is represented by a lumped single degree-of-freedom model, and the return spring is considered as a continuous element. Knowing the harmonic content of the forcing function, utilization of four-pole parameters enables a straighforward computational procedure to be developed for the determination of jump speed. For a typi...
An adaptive simulated annealing method for assembly line balancing and a case study
Güden, Hüseyin; Meral, Fatma Sedef; Department of Industrial Engineering (2006)
Assembly line balancing problem is one of the most studied NP-Hard problems. NP-Hardness leads us to search for a good solution instead of the optimal solution especially for the big-size problems. Meta-heuristic algorithms are the search methods which are developed to find good solutions to the big-size and combinatorial problems. In this study, it is aimed at solving the multi-objective multi-model assembly line balancing problem of a company. A meta-heuristic algorithm is developed to solve the determini...
