Multicriteria inventory classification using a genetic algorithm
(Elsevier, 1998) Guvenir, H. A.; Erel, E.
One of the application areas of genetic algorithms is parameter optimization. This paper addresses the problem of optimizing a set of parameters that represent the weights of criteria, where the sum of all weights is 1. A chromosome represents the values of the weights, possibly along with some cut-off points. A new crossover operation, called continuous uniform crossover, is proposed, such that it produces valid chromosomes given that the parent chromosomes are valid. The new crossover technique is applied to the problem of multicriteria inventory classification. The results are compared with the classical inventory classification technique using the Analytical Hierarchy Process. © 1998 Elsevier Science B.V.

A user-centered approach to green existing buildings : Bilkent University library as a case study
(2016-09) Okutan, Reyyan Sena
Decision-making in green design is a very complex process as it contains several alternatives for various criteria. In order to overcome this complexity, a holistic approach for the decision making process is needed. However, when green design is discussed, the main concerns of researchers or decision makers are reducing energy consumption. In fact, user involvement in sustainable decision making process is also a critical factor for the project success. Unfortunately, user centered design approach to green existing buildings especially the educational ones are scarce in the research area. Therefore, this thesis aims to develop a decision making model through a user centered design approach for Bilkent University Library. To achieve this, firstly user needs were identified and then they were prioritized via Analytical Hierarchy Process (AHP) by the designers. As result, acoustic comfort had the most importance weightings among the other design factors. Additionally, the needs of the different user groups of the library building, the students and the staff, compared, and it was observed that the library staff need the green solutions more than the students do.
