In this study, we identified one of the reasons of the low correlation between functional size and development effort which is overlooking the similarity of the functions during the mapping of the functional size and development effort. We developed a methodology (SiRFuS) that is based on the idea of the reuse of the similar functions internally to provide high correlation between functional size and development effort. The method is developed for the identification of the similar functions based on the method of Santillo and Abran. Similarity percentages among the functional processes and Similarity Reflective Functional Sizes are computed to attain adjusted functional sizes. The similarity reflective functional sizes were named as Discrete Similarity Reflective Functional Size and Continuous Similarity Reflective Functional Size based on the characteristics of the adjusted functional sizes. The SiRFuS method consists of three stages: measurement of the software product with COSMIC Functional Size Measurement (FSM) method; identification of the functional similarities bases on the measurement results and calculation of the similarity reflective functional sizes. In order to facilitate the detection of similar functions, calculation of the percentage of the similarities and similarity reflective functional sizes; a software tool is developed based on the SiRFuS method. Two case studies were performed in order to identify the improvement opportunities and evaluate the applicability of the method and the tool.

Mass customizing the relations of design constraints for designer-built computational models Ercan, Selen; Özkar, Mine; Department of Architecture (2010) The starting motivation of this study is to develop an intuitively strong approach to addressing architectural design problems through computational models. Within the scope of the thesis, the complexity of an architectural design problem is modeled computationally by translating the design reasoning into parameters, constraints and the relations between these. Such a model can easily become deterministic and defy its purpose, if it is customized with pre-defined and unchangeable relations between the const...
Capacity and tool allocation problem in flexible manufacturing systems Bilgin, Selin; Azizoğlu, Meral (2005-12-01) In this study, we consider capacity and tool allocation problem in flexible manufacturing environments. We assign the operations having priorities and processing requirements together with their required tools to a number of parallel machines having time and tool magazine capacities. We assume the number of available tools is limited and there is no partial operation assignments. Our aim is to maximize total weight over all assignments. We show that the problem is strongly NP-hard, and develop several appro...
Evaluation of the Effect of Functional Similarities on Development Effort Top, Ozden Ozcan; Tunalilar, Seckin; Demirörs, Onur (2008-09-05) Although functional size is the primary input for effort and cost estimation formulas, the relation between functional size and development effort does not always hold in practice. Calculating the magnitude of functional similarity is perceived as a partial solution to overcome this problem. In this study we applied different approaches to identify the magnitude of functional similarity in five projects. The applicability of these approaches is evaluated by observing the impact of functional similarity on e...
Making Functional Similarity Count for More Reliable Effort Prediction Models Top, Ozden Ozcan; Demirörs, Onur; Turetken, Oktay (2009-09-16) This paper evaluates the impact of functional similarities on the relation between functional size and software development effort. The estimation of the required effort cannot be achieved within reasonable limits at all times. We aimed to address this problem by considering functional similarities. Functional similarity is calculated for COSMIC measurement size results as adjusted functional sizes. The case study includes six cases. We discussed the challenges and the improvement opportunities of the method.
The effect of software design patterns on object-oriented software quality and maintainability Türk, Tuna; Bilgen, Semih; Department of Electrical and Electronics Engineering (2009) This study investigates the connection between design patterns, object oriented (OO) quality metrics and software maintainability. The literature on OO metrics, design patterns and software maintainability are reviewed, the relation between OO metrics and software maintainability is investigated, and then, in terms of obtained maintainability indicator metrics, the maintainability change of an application due to usage of design patterns is observed.
