Abstract: Traditionally, supplier-selection models have been based on quantitative data with less emphasis on qualitative data. However, with the expansion of manufacturing philosophies such as the just-in-time production, emphasis has shifted to the simultaneous consideration of quantitative and qualitative data in the supplier-selection process. Considering the supplier selection problem is a Complex and multi-criteria problem, one of the efficient models for selecting the best suppliers is Data envelopment analysis (DEA). Weight restrictions allow for the integration of expert opinion and controlling the range of weight changes in Data Envelopment analysis. So in this paper a new model with interval data envelopment analysis with considering the weight restrictions is presented.

Abstract: Supplier selection is one of the most important decision making problems including both qualitative and quantitative factors to identify Suppliers with the highest potential for meeting a firm’s needs consistently and at an acceptable cost and plays a key role in supply chain management (SCM).The purpose of this paper is applying a new integrated method to Supplier selection. Proposed approach is based on Logarithmic Fuzzy Preference Programming and Fuzzy GTMA (graph theory and matrix approach) methods. LFPP method is used in determining the weights of the criteria by decision makers and then rankings of Suppliers are determined by Fuzzy GTMA method. We apply the integrated approach in a real case to demonstrate the application of the proposed method.

Abstract: The objective of the study is to discuss the impact of current European debt crisis on the British economy. The study is based on different theoretically and descriptive data collected from different sources based on the crisis and on the economy of the British. Review of the literature was carried out for the data collection. The data was then analyzed by using the scanning and observation technique and all relevant data was selected for this study. All the findings were collected in a proper way to get the accurate results and conclude the study. The result demonstrates that in spite of the reality that the European crises have a negative impact on the United Kingdom’s (UK) economy the European Union (EU) membership also has certain benefits for UK. 50 % of overall trade of UK is with EU and if crisis hit Europe, it will ultimately have an impact on the economic activities within UK.  Inflation rate has raised, exports have dropped and the global competitiveness of the exporters has negatively impacted due to these crises. Euro zone crises are creating huge uncertainty which has reduce the public spending in euro-zone resulting in dropping the sales in UK. Furthermore the knockout effect will affect not only the companies with direct exposure in European market but also the SMEs and other larger businesses with no direct exposure to the Euro-zone. Modeling composting processes is the prerequisite to realize the process control of composting.

Abstract: The purpose of the current study is to provide an analytical tool to determinate the appropriate marketing strategy for the private hotels so as to capture sustainable competitive advantage. Given the complexity and difficulty of allocated specific and limited resources of marketing strategy toward competitive advantage for private hotels, hence, the current study is to employ the fuzzy analytic hierarchy process (FUZZY AHP) method to determinate competitive marketing strategy for private hotels. after reviewing the various opinions and research on competitive advantage in general, and particularly in service industries, resources and capabilities such as: managerial capabilities, customer linking capabilities, market innovation capabilities, human resource assets and reputational assets have been determined. Then, according to the above resources and also exploring in various comments and articles three types of appropriate marketing strategies determined: cost leadership strategy, differentiation strategy and the segmentation strategy to achieve competitive advantage for the private hotels. Due to a set of criteria for comparisons, the fuzzy analytic hierarchy process method is undertaken to accommodate the inherent uncertainty. the means of the tringular fuzzy numbers produced by managers of the private hotels for each comparison were successfully used in the pairwise comparison matrices The data obtained from questionnaires were analyzed using Fuzzy Analytical Hierarchy Process (FUZZY AHP). Results from analysis showed that according to sources and facilities said above, the most appropriate marketing strategy to achieve competitive advantage in the private hotels of Mazandaran province is the cost leadership strategy.

ABSTRACT: The Partition of India was the process of dividing the sub-continent along sectarian lines, which took place in 1947 as India gained its independence from British Empire. The northern part predominantly Muslim, became nation of Pakistan and the southern predominantly Hindu became the Republic of India, the partition however devastated both India and Pakistan as the process claimed many lives in riots, rapes, murders and looting. The two countries began their independence with ruined economies and lands without an established, experienced system of government, not only this, but also about 15 million people were displaced from their homes. The Partition of India was an important event not only in the history of the Indian subcontinent but in world history. Its chief reason was the communal thinking of both Hindus and Muslins; but the circumstances under which it occurred made it one of the saddest event of the history of India. No doubt, the Hindus and the Muslims were living together since long but they failed to inculcate the feelings of harmony and unity among themselves. The fanatic leaders of both communities played a prominent role in stoking the fire of communalism. The partition was exceptionally brutal and large in scale and unleashed misery and loss of lives and property as millions of refugees fled either Pakistan or India.

Abstract: Geophysical technique involving resistivity profiling was used to map LEA Primary School-Dagiri in Gwagwalada Area of the Federal Capital Territory with a view to investigate the lateral variation in the subsurface resistivity. The qualitative interpretation results identified the presence of fractures across the surveyed area. Three traverses each measuring 500m, (representing an area of 250,000m²) were mapped using wenner array configuration with electrode spacing of 50m for the profiling. Some prolific areas that can further be investigated for groundwater exploration using Vertical Electrical Sounding (VES) were delineated at the northeastern and Southern parts of the area. A resistivity range of 16Ωm - 1000Ωm was delineated, indicating a good groundwater potential area. Areas with resistivity values between 15Ωm and 265Ωm were however, marked as having good hydrogeologic significance in the region and consequently recommended for further investigation.

Abstract: Data envelopment analysis (DEA) has a wide application in measuring the relative efficiency of identical units with the same inputs and outputs. There are weaknesses in the classical models. One of the weaknesses is poor judgment and ranking among efficient decision making units, and another weakness is that the number of decision making units must greater than a certain limit. This model will not be valid when decision making units are relatively low. Also the most important weakness of classical model is changing weight of inputs and outputs that it makes the efficiency of decision units measured with different weight. Researchers believed that calculation with different weights for the same indexes in the set of homogeneous decision units is not logical. The important problem is how all decision units with a weight measured and simultaneously their efficiency is optimized. So, in this paper a model presented that all decision units measured with a weight and simultaneously efficiency of decision making units is optimized.
