The quality of water available to people has deteriorated because of the vast increase in global industries. The overall quality of water has reduced due to the high use of fertilizers in farms and chemicals in sectors such as mining and construction. The quality of water has a direct impact on the health of humans and hence it is necessary to evaluate the quality of drinking water. The quality of water is dependent on various substances like pH, ammonia, iron, arsenic etc. present in water. If these parameters are available in an appropriate amount in water then only the water is considered as of good quality. The problem of assessing water quality is usually considered as multi-criteria decision problem. In this paper an approach to evaluate quality of water using Fuzzy Analytical Hierarchical Process (Fuzzy-AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is proposed. The parameters which are considered for evaluation include Arsenic, Ammonia , Iron , Nitrate , Dissolved Oxygen and Ph. The relative importance of these parameters is utilized while applying the Fuzzy-AHP process and weights for each parameter are computed. The various datasets containing values for considered parameters are collected and the weights are used to assign quality levels to these water samples. The paper also gives the performance analysis of the proposed method in terms of accuracy. The accuracy is measured in terms of how many water samples are assigned correct quality level and the results show that the proposed method has better accuracy as compared to traditional AHP and Fuzzy-AHP method.
A fresh and creative approach to finance various business models is through crowdfunding, which enables individual business founders to submit fundraising requests. Businesses may be enlightening or commercial. Capitals are frequently given away in exchange for future goods or deeds. This entails connecting investors and businesspeople using social media on the internet in exchange for incentives to raise capital for various company models. Social networks and the Internet are becoming emerging platforms. The internet and social media are crucial for charitable organisations like dealers to raise money. After giving a general summary of the various crowdfunding platforms that have lately surfaced, this article first examines the role that technology plays in crowdfunding.
