An expert fuzzy system for management of railroad bridges in use
سیستم فازی تخصصی برای مدیریت پل های راه آهن در حال استفاده-2019 Management of railroad bridges constitutes a typical decision-making problem which arises from the necessity to
allocate limited financial resources to maintenance and repair work. It is a multiple criteria issue consisting in
the arrangement of bridges with regards to the level of structure degradation which is decisive for the safety
level of their users. So far, despite a large number of suggested calculation models, mainly of probabilistic
character, no method has been noticed that would allow to rank any number of bridges taking into consideration
a full variety of structure and material solutions. Therefore, in order to meet the need for a more effective model,
an innovative approach has been proposed using the aggregated calculation algorithm which combines the
modified Extent Analysis Fuzzy Analytic Hierarchy Process (EA FAHP) method and the Dominant Analytic
Hierarchy Process (DAHP) one. It is a decision-making and calculation model which allows to reflect the actual
assessment processes in a more favourable manner, as well as to take into account the diversity of solutions with
respect to materials and structure of bridges. An example was given of the application of the suggested method
on the selected group of railroad bridges in Poland that have been in use for over 50 years. The selected
structures have more diverse structures of decks and are more prone to damage than road bridges. Due to the
lack of algorithms similar to the one discussed within this paper, it was verified in a limited scope with the use of
two different methods by way of comparing the accordance of bridge ranking which is of importance for making
a decision concerning the performance of maintenance and repair work.

Green supply chain management related performance indicators in agro industry: A review
شاخص های عملکرد زنجیره تامین مدیریت سبز در صنایع کشاورزی: بررسی-2017 Environmental protection and sustainability issues in food sector have attracted global concerns in the
past two decades. Companies and government in many countries have started realizing the importance
of greening their supply chains. Green supply chain management has gained special attention of public
and many companies are now interested in adopting it as their strategy to advance their brand image,
capturing more market share and to win the trust of the customer. The purpose of this paper is to explore
the diverse performance indicators and sub-indicators responsible for green supply chain management
implementation and to check its reliability and to rank them using analytic hierarchy process analysis.
After extensive literature review and consulting Industrial experts, the study has suggested 13 perfor
mance indicators and 79 sub-indicators. The quantitative phase was conducted through a survey using
standard questionnaire with various agro based companies followed by a qualitative phase, where the
duly filled questionnaires were received, edited and further analyzed. It has been concluded that internal
environmental management, environmental design and regulatory pressure are ranked as the top three
performance indicators. The sensitivity analysis has also been performed to see the effect of weightage
on the final ranking of performance indicators. This is one of the first studies that suggest the perfor
mance indicators for implementation of green supply chain management in agro industry. The study will
certainly aid the related organizations to implement green supply chain management.

The synthetic geo-ecological environmental evaluation of a coastal coal-mining city using spatiotemporal big data: A case study in Longkou, China
ارزیابی زیست محیطی مصنوعی محیط زیست یک شهر زغال سنگ ساحلی با استفاده از داده های بزرگ و طولانی مدت: مطالعه موردی در Longkou، چین-2017 The geological and ecological (geo-ecological) environment of the coastal coal-mining city is a basic
element for human subsistence, and it connects the regional economy with social sustainable devel
opment. Using Longkou, a coastal mining city, as an example, a geological and ecological environmental
quality assessment was conducted based on spatiotemporal big data. Remote sensing images, a digital
elevation model (DEM), and precipitation and interpolation processing were used to generate factor
layers. A synthetic evaluation index system was set up, including physical geography, geological condi
tions, mining intensity, ecological environmental recovery and geological hazards associated with
mining. Moreover, an analytical hierarchy process was used to calculate the factor weight of each
evaluation factor, and a consistency check was performed to build an assessment model of the geo
ecological environment of Longkou. The results indicate that multi-factor spatiotemporal big data pro
vide a scientific assessment of the geo-ecological environmental quality with indispensable data and
methods. The spatial distribution of geo-ecological environmental quality presented clear specialization
of zonality, showing poor quality in the coastal coal mine ore concentration area and good quality in the
inland and mountainous areas of Nanshan Mountain. The geo-ecological environmental quality of
Longkou was divided into 5 levels as worst, poor, middle, good and better districts. The good and better
districts accounted for 76.763% of the total area of the assessment region, indicating that the geo
ecological environmental quality of the study area was in good condition. The mining intensity and
ecological environment recovery were major factors in determining the regional variation of the geo
ecological environment of Longkou. The possible causes inducing uncertainties and limitations in eval
uation of the geo-ecological environmental quality were discussed. The model combining AHP with GIS
proposed in this paper is an effective means of evaluating regional geo-ecological environmental quality.
