Spatial decision making problems are multi-facetted challenges. Not only they often involve numerous technical requirements, but may also contain economical, social, environmental and political dimensions that may have conflicting values. Solutions for these problems involve highly complex spatial data analysis processes and frequently require adva...

... also, lacks the capability of handling spatial data (e.g., buffering and overlay) that are crucial to spatial analysis. Malczewski (1999) suggested that there is a need for an explicit representation of geographical dimension in MCDM techniques. The combination of GIS and MCDM capabilities could effectively solve this problem. Malczewski (1999) has proposed a framework for spatial multicriteria decision analysis, as shown in figure 3. The concept of software interoperability is one of those buzzwords in the computer field that means different things to different people (Eddon and Eddon 1998). According to Goodchild et al. (1999) Interoperability means openness in the software industry, because open publication of internal data structures allows software users to use different software components from different developers to build their applications. It also means the ability to exchange data freely between systems, because each system would have knowledge of other systems’ formats. Interoperability also means commonality in user interaction, as system designers build interfaces that can be customized to a look and feel similar to the user. Wegner (1996) defined interoperability as “is the ability of two or more software components to cooperate despite differences in language, interface, and execution platform”. Interoperable systems are systems composed from autonomous, locally managed, heterogeneous components, which are required to cooperate to provide complex services (Finkelstein 1998). Although, Interoperability has been a basic requirement for modern information systems environment for over two decades (Sheth 1999), it is a recent research agenda element of geographic information science. To GIS users, interoperating GIS refers to the ability to exchange GIS data and functionality free among systems. Such interoperability can ...

The multicriteria methods based on pairwise comparisons suffer from possible rank reversal occurrences when the set of alternatives is modified. We study this distinctive feature in the scope of the PROMETHEE I and II methods. First, empirical tests are conducted on the basis of artificial datasets in order to quantify the likelihood of rank revers...

Many students have difficulty deciding on research ideas, supervision, and administration processes during the thesis writing process are ambiguous and as a result, they are unable to graduate on time. Behind this complex activity is the faculty who prepare on plotting for their schedule on proposal defense and final oral defense, taking down minutes of defense proceedings, and gathering rating sheets and different thesis documents from different thesis groups. This system's main objective is to offer a portal that will make it simpler to follow and finish the thesis cycle. Part of the thesis cycle is the scheduling of oral defense by the students to the panel members; automating the defense scheduling is a key to fast-tracking the thesis cycle process. The automated defense schedule in this paper is implemented using a genetic algorithm. To evaluate the system's functionality and usability, standard usability tests are carried out. Results show that 94% of the system is appropriate and recognizable and the system’s overall functionality is 84%. Hence, the study on automating the thesis cycle, which includes automated defense scheduling, can address the problems in the execution of theses document gatherings, retrieving defense minutes, and scheduling oral defense presentations
