ABSTRACT India experiences rainfall from southwest and northeast monsoon, with large spatial and temporal variability reported in recent years. Rainfall trend could be essential for disaster preparedness or long-term planning of agriculture and economic advancement. Long-term and short-term trends observed in rainfall across different subdivisions of India could be different. The result of trend (or any other) analysis could vary when different tests are employed and hence it is advisable to employ more than one test for any statistical check. Therefore, four tests were employed for detection of trend including Mann-Kendall test, Spearman’s Rank Order Correlation test, Wald-Wolfowitz Run test on data, and Wald-Wolfowitz Run test on successive difference of data; and the slopes were estimated by Sen’s slope as well as linear regression analysis. For detection of possible change point, the four tests included Pettitt’s test, Von Neumann Ratio test, Buishand’s Range test, and the graphical test of Cumulative Departures from Mean. Cases of conflicting results in the four tests were addressed with categorical inferences: useful (one or less test rejects null hypothesis); doubtful (two tests reject null hypothesis); suspect (three or more test rejects null hypothesis) – based on approach described in literature. For seven subdivisions in India, trend was statistically significant at 5% level, out of which for five subdivisions, change point was also identified. Decreasing trend was observed for: Nagaland, Manipur, Mizoram, and Tripura; East Uttar Pradesh; East Madhya Pradesh; and Chhattisgarh, whereas increasing trends were identified for Konkan and Goa; Coastal Karnataka; and Telangana. Change point was detected for four other subdivisions as well. The mean was observed to be unstable for nineteen subdivisions, which included all nine subdivisions with identified change points. The short-term trend was found to be at variance with the long term trend in several subdivisions and significant trend was observed for Saurashtra, Kutch and Diu in the last quarter period (1980–2016). Such findings highlight the necessity of short-term trend analysis for indications of possible climate change effects on recent rainfall records.
印度的降水来自西南季风和东北季风，近年来有较大的时空变异报道。降雨趋势对备灾或农业和经济发展的长期规划至关重要。在印度不同地区观测到的长期和短期降雨趋势可能不同。当采用不同的检验时，趋势(或任何其他)分析的结果可能会有所不同，因此建议对任何统计检查采用多个检验。因此，采用Mann-Kendall检验、Spearman秩序相关检验、数据的Wald-Wolfowitz Run检验和数据连续差异的Wald-Wolfowitz Run检验四种检验进行趋势检测;用Sen 's斜率和线性回归分析估计斜率。对于可能变化点的检测，采用了Pettitt检验、Von Neumann Ratio检验、Buishand’s Range检验和Cumulative Departures from Mean图形检验。四个检验中相互冲突的结果通过分类推断来解决:有用的(一个或更少的检验拒绝零假设);可疑的(两个检验拒绝原假设);怀疑(三个或更多的检验拒绝零假设)-基于文献中描述的方法。对于印度的七个细分市场，趋势在5%的水平上具有统计学意义，其中五个细分市场也确定了变化点。下降趋势出现在:那加兰邦、曼尼普尔邦、米佐拉姆邦和特里普拉邦;东北方邦;中央邦东部;而康坎邦和果阿邦则有上升趋势;沿海卡纳塔克邦;建邦者和纳。另外四个细分也检测到了变化点。我们观察到19个细分的平均值是不稳定的，其中包括所有具有确定的变化点的9个细分。研究发现，几个细分市场的短期趋势与长期趋势存在差异，上一季度(1980-2016年)，Saurashtra、Kutch和Diu的趋势显著。这些发现突出了短期趋势分析的必要性，以表明气候变化对近期降雨记录可能产生的影响。

ABSTRACT Three objectives, maximization of resilience, minimization of cost, and minimization of leakages, were considered in the Water Distribution Network (WDN) framework for a benchmark problem of Hanoi WDN and a real-world problem, Pamapur WDN, Telangana, India. Non-dominated Sorting Genetic Algorithm-II (NSGA-II) is employed to generate Non-dominated WDN Strategies (NWDNS). In order to simplify the decision-making process of engineers, Fuzzy Cluster Analysis (FCA) is employed to categorize NWDNS into groups. An optimum number of clusters are based on the Elbow method. Representative NWDNS, i.e. RNWDNS for each sub-cluster, is based on the membership values. Ranking of RNWDNS is performed with two decision-making algorithms, namely, Preference Ranking Organization METHod for Enrichment of Evaluations-2 (PROMETHEE-2) and VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR). The additive ranking rule is also applied to obtain ranks in a group decision-making environment to arrive at the optimal WDN. It is observed that 1020 NWDNSH (H represents Hanoi) generated for the Hanoi are optimally classified into 18 clusters based on the Elbow method, and A13 representing RNWDNSH 37 (cost, resilience, and leakages, respectively, are 7.8818 × 106 $, 0.3194, 0.2024 × 10−3 m3/s) is preferable, respectively. Whereas 272 NWDNSP (P represents Pamapur) generated for the Pamapur are classified into 9 clusters where S6 representing RNWDNSP 203 (cost, resilience, and leakages, respectively, are 3.5159 × 106 Rs., 0.8367, 0.5317 × 10−3 m3/s) is preferred, respectively. The present study facilitated seamless integration of NSGA-II (generation of Pareto front), FCA (reducing to manageable set) and MCDM methods (to rank the reduced manageable set) in a robust manner.
