Kartik Patra, Shyamal Kumar Mondal

In this paper, a supplier selection model was developed for a retailer. Suppliers have different influence factors that have a risk of profit loss or less profit as well as a loss of goodwill to a retailer. Thus, a retailer must choose a supplier that can provide better profit and better goodwill. Different suppliers have different business policies. Here, different risk factors and their corresponding severity in profit loss and goodwill loss are considered as a fuzzy number. Next, the total risk in profit loss and goodwill loss is formulated. To select a supplier with the minimum risk, a balanced solution of the soft set theory was applied to a numerical example.

本文建立了一个零售商的供应商选择模型。供应商有不同的影响因素,有利润损失或利润减少的风险,以及对零售商的商誉损失。因此,零售商必须选择一个供应商,可以提供更好的利润和更好的商誉。不同的供应商有不同的业务策略。在这里,利润损失和商誉损失中的不同风险因素及其相应的严重程度被认为是一个模糊数。其次,制定利润损失和商誉损失的总风险。为了选择风险最小的供应商,将软集理论的平衡解应用到数值算例中。

Optimum connection of LSF system braces using the seismic-ANN approach 用地震神经网络方法优化LSF系统支架的连接

Lightweight steel framing (LSF) has been proposed as an economic and earthquake-resistant system. The tendency of mass constructors to use this system is due to it being a full industrial process. One of the systems that resist lateral load in cold-formed steel structures is the application of braces. Optimization and improvement of connections for these braces have been considered by experts in this field of research. In this paper, experimental studies and normalization and simulation by artificial neural network (ANN) were used. The results of the research have been applied to create a nonlinear relationship. All input and target data must be normalized and then simulation and training by a neural network can be performed. In this research, two layers have been used. One of these is a sigmoid layer. The results show that optimal connections in light weight steel framing systems have suitable plasticity, load capacity and nonlinear relations. Statistical analysis with SPSS software shows that there is no significant difference between the neural network and experimental results (P-Value > 0.05).

轻钢框架是一种经济、抗震的结构体系。大量建筑商使用该系统的趋势是由于它是一个完整的工业过程。在冷弯型钢结构中,支撑的应用是抵抗横向荷载的系统之一。这些牙套连接的优化和改进已被该研究领域的专家所考虑。本文采用实验研究和人工神经网络(ANN)归一化仿真方法。研究结果已被应用于建立一个非线性关系。所有的输入和目标数据必须经过归一化处理,然后用神经网络进行模拟和训练。在本研究中,使用了两层。其中一个是s形层。结果表明,轻钢框架结构的最优连接具有合适的塑性、承载能力和非线性关系。用SPSS软件进行统计分析表明,神经网络与实验结果无显著差异(p值>0.05)。

This paper introduces a simplified distributed rainfall-runoff model based on the combination of a finite element model with the US SCS method. Excess rainfall is estimated from rainfall, soil and land-use properties according to the SCS. The approximation of river flow uses finite elements, while overland and channel flows are simulated by one-dimensional kinematic wave equations. The finite element algorithm for solving the one-dimensional kinematic wave equations is based on lumped schemes and a third order Runge–Kutta method. The proposed model is applied to estimate the flood flow in the Tra Khuc River Basin. The obtained results show the promise of this method for practical application.

本文介绍了一种基于有限元模型与美国SCS方法相结合的简化分布式降雨径流模型。超额雨量是根据雨量、土壤和土地用途属性,根据《标准说明》估算的。河流流量的近似采用有限元法,而陆地和河道流量的模拟采用一维运动波动方程。求解一维运动波动方程的有限元算法是基于集总格式和三阶龙格-库塔法。将该模型应用于特拉胡克河流域的洪水流量估算。所得结果表明该方法具有实际应用的前景。

Range-valued fuzzy colouring of interval-valued fuzzy graphs 区间值模糊图的范围值模糊着色
Pub Date : 2016-11-01 DOI: 10.1016/j.psra.2016.09.006
S. Satyanarayana

In this paper, we observed that range-valued fuzzy graphs are more popular than fuzzy graphs following the level of participation of nodes and branches in the range [0, 1] other than at a point in fuzzy graphs. Colouring interval-valued fuzzy graphs has a few general applications. In this paper, another idea of using colouring for interval-valued fuzzy graphs is presented. Additionally, a few vital terms, such as power cut graphs, interval-valued fuzzy colour, and chromatic numbers of interval-valued fuzzy graphs, are depicted. Some important theorems are discussed. This procedure is utilized to colour the India political map, revealing the power of the relationship within the nation. Additionally, another sort of traffic signal system is analysed.

在本文中,我们观察到区间值模糊图比模糊图更受欢迎,在区间[0,1]内的节点和分支的参与程度,而不是模糊图中的某一点。区间值模糊图的着色有一些一般的应用。本文提出了在区间值模糊图中使用着色的另一种思想。此外,还描述了一些重要的术语,如断电图、区间值模糊颜色和区间值模糊图的色数。讨论了一些重要的定理。这一过程被用来为印度的政治地图着色,揭示了国家内部关系的力量。此外,还对另一种交通信号系统进行了分析。
