Pasi Luukka. School of Business and Management, Lappeenranta University of Technology

Mikael Collan. School of Business and Management, Lappeenranta University of Technology

Peer-assessment between students is a way to include evaluation as a part of the learning process and to simultaneously cut teacher load in grading of assignments. eLearning systems can be used to automate peer-assessment to a large extent. Peer-assessment benefits from multiple-peer-assessment as it is likely to even-out outliers. Linguistic…

VALUATION OF REAL OPTIONS IN INCOMPLETE MODELS – AN IMPLIED YIELD APPROACH

Fredrik Armerin. Department of Real Estate and Construction Management, School of Architecture and the Built Environment, KTH Royal Institute of Technology

This creates more information about the importance of the effect of selected factors to investment profitability. Furthermore,…

UTILIZING INTERVALS OF VALUES IN MODELING DUE TO DIVERSITY OF MEASUREMENTS

Eli Shnaider. Peres Academic Center, Israel

Arthur Yosef. Tel Aviv-Yaffo Academic College, Israel

Model-building professionals are often facing a very difficult choice of selecting relevant variable/s from a set of several similar variables. All those variables are supposedly representing the same factor but are measured differently. They are based on different methodologies, baselines, conversion/comparability methods, etc., thus leading to substantial differences in numerical…

DEVELOPING A GENERALIZED FUZZY MULTI-CRITERIA DECISION MAKING FOR PERSONNEL SELECTION

This paper proposes an extension of fuzzy multi-criteria decision making (MCDM) method for supporting the personnel selection process. In the proposed method, the ratings of various alternatives versus various subjective criteria and the weights of all criteria are assessed in linguistic terms represented by generalized fuzzy numbers. Then, the weighted…
