A fuzzy QFD approach to determine supply chain management strategies in the dairy industry
The aim of this study is to identify the crucial logistics requirements and supply chain management (SCM) strategies for the dairy industry. For product or service development quality function deployment (QFD) is a useful approach to maximize customer satisfaction. The determination of design requirements and supply chain management strategies are important issues during QFD processes for product or service design. For this reason a fuzzy QFD methodology is proposed in this study to determine these ...

A multi-objective mathematical model for the industrial hazardous waste location-routing problem
Industrial hazardous waste management involves the collection transportation treatment recycling and disposal of industrial hazardous materials that pose risk to their surroundings. In this paper a new multiobjective location-routing model is developed and implemented in the Marmara region of Turkey. The aim of the model is to help decision makers decide on locations of treatment centers utilizing different technologies routing different types of industrial hazardous wastes to compatible treatment ...

An interactive memetic algorithm for production and manufacturing problems modelled as a multi-objective travelling salesman problem
Authors:Samanlioglu, Funda; Ferrell, William G.; Kurz, M. E.
Publisher and Date:(Taylor & Francis Ltd, 2012)In this paper a preference-based interactive memetic random-key genetic algorithm (PIMRKGA) is developed and used to find (weakly) Pareto optimal solutions to manufacturing and production problems that can be modelled as a symmetric multi-objective travelling salesman problem. Since there are a large number of solutions to these kinds of problems to reduce the computational effort and to provide more desirable and meaningful solutions to the decision maker this research focuses on using interactive ...

Analytic Network Process (ANP) for solar power plant location problem
Solar energy is the most readily available source of energy and one of the most important sources of the renewable energy because it is non-polluting and helps in lessening the greenhouse effect. Main problem of establishing a solar power plant is to determine its location. In the presence of many location alternatives and evaluation criteria a multiple-criteria decision making problem arises. In this work the location problem will be solved by using Analytic Network Process (ANP) to figure out ...

Computing trade-offs in robust design: Perspectives of the mean squared error
Authors:Shin, Sangmun; Samanlioglu, Funda; Cho, Byung Rae; Wiecek, Margaret M.
Publisher and Date:(Pergamon-Elsevier Science Ltd, 2011)Researchers often identify robust design as one of the most effective engineering design methods for continuous quality improvement. When more than one quality characteristic is considered an important question is how to trade off robust design solutions. In this paper we consider a bi-objective robust design problem for which Pareto solutions of two quality characteristics need to be obtained. In practical robust design applications a second-order polynomial model is adequate to accommodate the ...

Determining master schedule of surgical operations by integer programming: A case study
Authors:Samanlioglu, Funda; Ayaǧ, Zeki; Batili, Burcin; Evcimen, Esra; Yılmaz, Gulsah; Atalay, Ozlem
Publisher and Date:(Institute of Industrial Engineers, 2010)Fixed amounts of available Operating Room (OR) time compatibility of ORs and restrictions related to surgery equipment and surgeon availabilities complicate the process of preparing the master surgical schedule at hospitals. In this research an integer programming model and its application at Etiler World Eye Hospital (in Turkey) are presented in order to create a master surgical schedule that includes the most common surgery types on weekly basis and resolves surgeon equipment and operating room ...

Efficient approaches for furnace loading of cylindrical parts
Authors:Osman, Mojahid Saeed; Ram, Bala; Samanlioglu, Funda
Publisher and Date:(Elsevier Science Inc, 2014)This paper addresses the heat treatment operation in a manufacturing plant that produces different types of cylindrical parts. The immediate prior process to heat treatment is furnace-loading where parts are loaded into baskets. The furnace-loading process is complex and involves issues relating to geometry and heterogeneity in the parts and in their processing requirements. Currently furnace-loading is accomplished by operator ingenuity ; consequently the parts loaded in heat treatment often do ...

Fuzzy AHP-GRA approach to evaluating energy sources: a case of Turkey
Purpose Since the demand for energy has dramatically increased in the countries which have fast-growing population and economy, they have faced with a critical problem of how to evaluate a set of potential energy sources (i.e. nuclear, natural gas, bio, geothermal, hydro, wind and solar) and choose the ultimate energy source for their needs. On the other hand, this critical problem turns into a multiple-criteria decision-making (MCDM) in the presence of a set of energy source alternatives and ...

Inventory planning and coordination in disaster relief efforts
Authors:Davis, Lauren B.; Samanlioglu, Funda; Qu, Xiuli; Root, Sarah
Publisher and Date:(Elsevier Science Bv, 2013)This research proposes a stochastic programming model to determine how supplies should be positioned and distributed among a network of cooperative warehouses. The model incorporates constraints that enforce equity in service while also considering traffic congestion resulting from possible evacuation behavior and time constraints for providing effective response. We make use of short-term information (e.g. hurricane forecasts) to more effectively preposition supplies in preparation for their ...

Multi - objective location routing problem for nuclear power plants and nuclear waste disposal centers
Nuclear energy is used by many countries and has already taken its place among the future sources of energy. in Turkey nuclear energy has recently been accepted by the majority of people as an alternative energy source. As a result inspections and research have accelerated to establish a nuclear power plant. in this thesis a new multi-objective location-routing mathematical model is developed and implemented using actual data for Turkey. The model selects best locations for nuclear power plants ...

Optimization Model for Distributed Routing for Disaster Area Logistics
Authors:Osman, Mojahid Saeed; Ram, Bala; Bhadury, Joy; Stanfield, Paul; Davis, Lauren B.; Samanlioglu, Funda
Publisher and Date:(IEEE, 2009)The problem of transportation in a disaster area can be seen broadly as having two aspects: (a) moving people and materials out of an area and (b) moving people and materiel into the same area. The common thread here is the use of a limited set of surface and air transportation gateways into and out of the area. The distributed routing problem here is that of assigning one from among the limited set of gateways to various transportation requests in real-time while maximizing some measure of success ...

Radio frequency identification system optimisation models for lifecycle of a durable product
Authors:Osman, Mojahid Saeed; Ram, Bala; Stanfield, Paul; Samanlioglu, Funda; Davis, Lauren B.; Bhadury, Joy
Publisher and Date:(Taylor & Francis Ltd, 2010)We address the implementation of radio frequency identification (RFID) technology to support and manage durable products over their entire lifecycle with a focus on optimising the RFID tagging system. We develop general models that optimise the placement of RFID tags on an end product and its components the allocation of the data on tags and the selection of RFID tags and their configuration. The primary criteria for optimisation are to maximise the value of RFID data and to minimise the total ...
