[ 1 ] - بهکارگیری بانک داده بهمنظور تحلیل کمی ریسک طرحهای سرمایهگذاری صنعتی بهکمک روش تاپسیس
یکی از مشکلات رایج در مراحل مختلف اجرای طرحها، تأخیرات مکرر در تکمیل آنهاست. مهمترین دلیل این امر وجود ریسک و عدمقطعیتهای داخلی و خارجی است. برای رفع این مشکل برنامهیی لازم است که بتوان ریسک و عدم قطعیتها را بهطور مؤثر مدیریت، و آثار نامطلوب آنها بر اهداف طرح را کمینه کرد. در این نوشتار بهمنظور تحلیل کمی ریسکهای موجود در طرحهای سرمایهگذاری صنعتی بهکارگیری بانک داده با پشتیبانی روش...
[ 2 ] - Resource Constrained Project Scheduling with Material Ordering: Two Hybridized Meta-Heuristic Approaches (TECHNICAL NOTE)
Resource constrained project scheduling problem (RCPSP) is mainly investigated with the objective of either minimizing project makespan or maximizing project net present value. However, when material planning plays a key role in a project, the existing models cannot help determining material ordering plans to minimize material costs. In this paper, the RCPSP incorporated with the material order...
[ 3 ] - A Closed-Form Formula for the Fair Allocation of Gains in Cooperative N-Person Games
Abstract This paper provides a closed-form optimal solution to the multi-objective model of the fair allocation of gains obtained by cooperation among all players. The optimality of the proposed solution is first proved. Then, the properties of the proposed solution are investigated. At the end, a numerical example in inventory control environment is given to demonstrate the application and t...
[ 4 ] - A Simple Transformation Method in Skewness Reduction
Statistical analysis of non-normal data is usually more complicated than that for normaldistribution. In this paper, a simple root/power transformation technique developed by Niaki, et al [1]is extended to transform right and left skewed distributions to nearly normal. The value of theroot/power is explored such that the skewness of the transformed data becomes almost zero with anacceptable err...
