Solution methods for a min-max facility location problem with regional customers considering closest Euclidean distances
DOLU HASTÜRK, NAZLI; HASTÜRK, UMUR; Tural, Mustafa Kemal (Springer Science and Business Media LLC, 2020-03-01)
We study a facility location problem where a single facility serves multiple customers each represented by a (possibly non-convex) region in the plane. The aim of the problem is to locate a single facility in the plane so that the maximum of the closest Euclidean distances between the facility and the customer regions is minimized. Assuming that each customer region is mixed-integer second order cone representable, we firstly give a mixed-integer second order cone programming formulation of the problem. Sec...
Solution approaches for single-source capacitated multi facility weber problem
Damgacıoğlu, Haluk; İyigün, Cem; Department of Industrial Engineering (2014)
Single Source Capacitated Multi Facility Location Problem (SSCMFLP) is a continuous location-allocation problem such that determining the locations of p facilities in the plane and allocations of n demand points to only one facility by considering the capacity restriction of each facility so as to minimize total transportation cost to satisfy n demand points from p facilities. In addition to Mixed Integer Non-Linear Programming formulation of the problem in the literature, we give a new formulation for the ...
Solution approaches for flexible job shop scheduling problems
Balcı, Şerife Aytuğ; Azizoğlu, Meral; Oğuzsoy, Cemal Berk; Department of Industrial Engineering (2013)
In this thesis, we consider a flexible job shop scheduling problem existing in discrete parts manufacturing industries. We are motivated by the production environment of Roketsan Missiles Industries Incorporation, operating at Turkish defense industry. Our objective is to minimize the total weighted completion times of the jobs in the system. We formulate the problem as a mixed integer linear program and find that our model could find optimal solutions only to small sized problem instances. For medium and l...
