This paper presents a new approach for the treatment of uncertainty which is based on interval rough numbers (IRN). IRN based approach uses only internal knowledge i.e. operational data without relying on assumption models. In other words, instead of various additional/external parameters, IRN uses only the structure of the existing data. Based on the IRN there has been developed a novel IRAHP ...

AHP (Analytic Hierarchy Process) has been widely used in decision making techniques. However, the results from AHP often lose reliability because the comparison matrix does not always have sufficient consistency. In these cases, fuzzy representation for weighting activities using results from a sensitivity analysis is useful. In this paper, we present alternative overall weights by employing so...

It is demonstrated the need for organizations to implement a set of performance measures that is multi dimensional. The most widely known approach to performance measurement, the Balanced Scorecard is now widely used as a strategy development and execution tool but was developed in an operational environment. The present study tried to point out factors affecting launching and implementing Bala...

Literature indicates that comparative ratios provide ambiguous and inaccurate judgments in many cases. Quality forecasts have been relatively more successful when compared to quantitative estimates. The uncertainty in preferential judgment leads to uncertainty in classification of other options and difficulty in stabilization of preferences. The objective of this article was to study and evalua...

In looking for different types of large-scale activities of food sanitation supervision and security modes, improving the efficiency of food hygiene protection, this paper establishes the evaluation index system for sports food hygiene, and proposed the sports food hygiene evaluation model based on the Analytic Hierarchy Process (AHP) and the interval fuzzy TOPSIS method. AHP is used to determi...

With the development of society, high-level applied students have been an urgent demand and the quality of entrepreneurial education of postgraduate has attracted more and more attention. Based on the requirements of universities society and enterprise for the comprehensive ability of postgraduate, we proposed the evaluation index system and used AHP-fuzzy comprehensive evaluation approach, whi...

This study was carried out to evaluate the capability of a combined fuzzy-analytic hierarchy process (AHP) method for soil fertility evaluation of common bean in Shiraz, Iran. A set of membership functions was constructed to represent the soil fertility classes, which were derived from 50 field samples collected through a purposive sampling approach. Seven soil parameters including phosphorus (...

Saffron is the most expensive spice and is significantly valuable in non-oil export. Drying process of saffron is considered as a critical control point with major effects on quality and safety parameters. A suitable drying method covering standards and market requirements while it is costlty benefitial and saves energy is desirable. Solar drying could be introduced as an appropriate procedure ...
