Interpretive Structural Modeling (ISM) is a technique to establish the interrelationships between elements of interest in a specific domain through experts’ knowledge of the context of the elements. ...This technique has been applied in numerous domains and the list continues to grow due to its simplistic concept, while sustainability has taken the lead. The partially automated or manual application of this technique has been prone to errors as witnessed in the literature due to a series of mathematical steps of higher-order computing complexity. Therefore, this work proposes to develop an end-to-end graphical software, SmartISM, to implement ISM technique and MICMAC (Matrice d’Impacts Croisés Multiplication Appliquée á un Classement (cross-impact matrix multiplication applied to classification)), generally applied along with ISM to classify variables. Further, a scoping review has been conducted to study the applications of ISM in the previous studies using Denyer and Tranfield’s (2009) framework and newly developed SmartISM. For the development of SmartISM, Microsoft Excel software has been used, and relevant algorithms and VBA (Visual Basic for Applications) functions have been illustrated. For the transitivity calculation the Warshall algorithm has been used and a new algorithm reduced conical matrix has been introduced to remove edges while retaining the reachability of variables and structure of digraph in the final model. The scoping review results demonstrate 21 different domains such as sustainability, supply chain and logistics, information technology, energy, human resource, marketing, and operations among others; numerous types of constructs such as enablers, barriers, critical success factors, strategies, practices, among others, and their numbers varied from 5 to 32; number of decision makers ranged between 2 to 120 with a median value of 11, and belong to academia, industry, and/or government; and usage of multiple techniques of discourse and survey for decision making and data collection. Furthermore, the SmartISM reproduced results show that only 29 out of 77 studies selected have a correct application of ISM after discounting the generalized transitivity incorporation. The outcome of this work will help in more informed applications of this technique in newer domains and utilization of SmartISM to efficiently model the interrelationships among variables.

The test method used is the Black Box Method, the results of the execution are through testing and checking the functionality of the software. the design of the goods management information system is operated by processing goods data by inputting, editing, deleting and displaying reports (reports) based on the Visual Basic 10 application. Test results The interface-based goods management application system helps the admin in inputting incoming and outgoing goods data and managing and regulate the release and entry of goods.
The Kainji hydropower station is a seven turbo-alternator station that for many years served as the base load supply for the Nigerian power grid. Over 200,000 pieces of data about the performance of ...the machines were used to estimate values of the failure and repair rates for each machine and a Markov steady-state model of the plant was constructed to determine the probability output of the turbines. This result showed that Kaplan turbine (KT) 12 is prone to failure compared to any other KT unit in the hydropower plant. Also, the clusters of probability that define the system state due to the different output capacities of the units show that the hydropower plant has not performed to its maximum capacity, further evaluation shows that 60% of the KT machine units are operating which is consistent with the observed robustness of the output. The model not only conforms to observations but reasonably provide a means of studying the effects of different actions that may be taken to improve the performance of hydropower plant.
Frequentemente as cidades brasileiras sofrem com inundações, deslizamentos e erosões causadas pelo escoamento superficial da água da chuva. Os sistemas de drenagem urbanos sustentáveis incorporam ...técnicas de infiltração, evaporação e retenção do escoamento superficial com o objetivo de mimetizar o ciclo hidrológico pré-urbanização. Este trabalho adapta e aplica a metodologia de eventos de chuva característicos (ECC) a partir de uma série histórica de dados pluviométricos para simulação do comportamento hidrológico de poços de infiltração no município de São Carlos/SP. O método ECC busca auxiliar os profissionais que trabalham com dispositivos de drenagem a melhor entender o comportamento desses em um cenário de chuva real. Foram determinados ECC para seis categorias de tempo de retorno, utilizando os dados da estação automática do Instituto Nacional de Meteorologia (INMET) através de rotina de cálculos programados em Visual Basic for Applications (VBA). Os ECC são uma forma matematicamente confiável de escolha de um evento pluviométrico histórico para simulação do comportamento de dispositivos de drenagem urbana mais sustentável.

Renewable technologies are a modern, clean form of energy with a very low environmental impact. They can become a viable option for energy generation, especially in rural areas of Ecuador, where the ...scarce access to electricity service limits the development possibilities of these areas. Solar energy is the resource used by off grid photovoltaic generation systems, which are used exclusively in rural areas because the installation of the electrical grid is costly or technically complex.
In the Matlab/Simulink environment, off grid photovoltaic systems have been designed, which are composed of an array of photovoltaic modules, charge controllers, storage systems and single-phase inverters that together will allow knowing the behavior of electric power generation through solar photovoltaic energy. In addition, a maximum power point tracking (MPPT) algorithm was developed to obtain the peak power of the photovoltaic array and a discrete integral proportional control was incorporated for the charging and discharging of the batteries. Finally, a sizing tool was designed and developed through Excel Macros and Visual Basic, which facilitated the input of the different parameters and the obtaining of the results for the implementation of the photovoltaic systems.
