Pengambilan Keputusan Pemilihan Pemasok Di Perusahaan Manufaktur Dengan Metode Fuzzy ANP

. The issue of supplier selection is an important issue in the company because it will determine the company's ability to ensure the availability of raw materials in production. This study aims to establish a decision-making model for supplier selection which considers many criteria in which there is dependence between criteria. The method used is fuzzy-analytic network process (fuzzy-ANP). The combined fuzzy and ANP methods is used not only to consider dependencies between criteria, but also to minimize uncertainty and inaccuracy in the assessment of importance of each criterion. Four major stages used in the decision model, namely the establishment of supplier selection criteria and sub-criteria, the process of determining dependencies among the criteria, the weighting of the criteria/sub-criteria, and the last one is supplier assessment process. The process of weighting the criteria results in two data, criteria weights without dependency and criteria weights with dependency. The process of formation of criteria/sub-criteria and the ratings to generate weights were obtained from the experts from the company where case study was done. Supplier rsting process is done through assessment process using the 5 (five) scale rating. The results of rating for each supplier will then be compared. The results of this method is the ranking of suppliers in a certain procurement process. From this research it is known that the method used, fuzzy ANP, is proved to be appropriate considering that there are dependencies among the criteria/ sub-criteria used and the method is useful to minimize uncertainty or inaccuracy in the assessment process. By employing this method, criteria with the highest weight was obtained, that is quality of human resources which affect as much as 6 other criteria, followed by quality of product, supplier's reputation, price, and delivery method

Experimental and Numerical Studies on Setback Buildings Considering the SSI Effect under Seismic Response

From the previous studies it is observed that due to the effect of the earthquake, several irregular buildings failed vulnerably. Further the effect of sub soil conditions where these buildings have been founded also play an important role on the seismic response of these buildings. In the past, experimental studies on the seismic response of different setback building configurations have not been carried out. Therefore, in the present study the seismic behaviour of setback buildings considering Soil Structure Interaction (SSI) has been evaluated by conducting experimental and numerical investigations. Buildings with various setback configurations were considered and are designed as pile foundation supported structures. The irregularity index of these building configurations have been determined as per the existing codal provisions. These piles supported buildings representing the prototype structure have been scaled down according to geometric, kinematic and dynamic scaling laws. The scaled building models are subjected to vibrations beyond resonant frequencies using shake table facility. A comparison of the results has been made between experimental and numerical investigations. Based on the study it has been observed that storey displacements of building with regular configurations are higher in comparison with the setback buildings. It is also found that asymmetrical and symmetrical setback buildings having different irregularity indices as per IS:1893-2016 indicate nearly the same displacements at resonant frequencies. Doi: 10.28991/cej-2021-03091664 Full Text: PD

Meglumine efficiently catalyzes the one-pot, five-component reaction of hydrazine, ethyl acetoacetate, aryl aldehydes, substituted phenylacetonitriles and ammonium acetate in ethanol at room temperature to afford novel 4,7-dihydro-1H-pyrazolo3,4-bpyridin-6-amine derivatives. The present approach offers several advantages such as shorter reaction durations, low cost, excellent yields, milder reaction conditions, simple workup procedure and is environment friendly. All the synthesized derivatives are characterized by IR,1H NMR,13C NMR, HRMS and CHN analysis. � 2016 Mohamed Afzal Pash

Modelling the Role of Active Biomass on the Fate and Transport of a Heavy Metal in the Presence of Root Exudates

The influence of active biomass in immobilizing heavy metals in the soil rhizosphere is investigated through mechanistic models. The movement of water in the soil is modeled using Richards equation. An advection-dispersion equation, with a sink term for metal uptake by biomass, is used for modeling the fate and transport of lead. This sink term represents the nonlinear kinetics of metal adsorption to the biomass that is partitioned into mobile and stationary fractions within the soil. Transport of the mobile biomass fraction is modeled by an advection-dispersion equation, with a source term that is based on Monod growth kinetics, and a linear sink term for endogenous decay. The movement of metal in association with mobile biomass is also included as a transport mechanism for lead. Root exudates serve as carbon substrate for the biomass growth, and their transport is modeled in a similar way as that of the biomass. A hypothetical one-dimensional vertical soil column containing metal, biomass and a carbon substrate is used for analyzing lead movement. Model simulations demonstrate the influence of water content, growth rate of biomass, partitioning coefficient of biomass between soil and aqueous phase, and partitioning coefficient of metal between biomass and aqueous phase of the soil on fate and transport of lead. The extent of immobilization of lead in soil is found to be dependent on the growth of biomass, which in turn depends on the availability of root exudates in the rhizosphere. Apart from analyzing different scenarios, such a model can be used for designing future experiments

Pengembangan Model Evaluasi Kualitas Layanan Sistem E-Government

. In many countries, e-government system has been built to support the government in providing services to the community and industry. Although the system had been developed and has been successfully executed, the level of user acceptance and the quality level of service is often not satisfactory. The aim of this study is to develop a model for of e-government system evaluation. E-government evaluation model was developed by combining aspects of government services (public services) as well as aspects of service quality of electronic-based systems. The model was tested using empirical data. Questionnaires filled online using a web-based application, 108 samples were collected and 88 samples were declared valid to be used for measurement model analysis and e-government system evaluation. Analysis of reliability and validity of the measurement model was conducted using partial least square (PLS) technique. Analysis of the e-government system evaluation results was carried out by utilizing importance-performance analysis (IPA) method. The model developed is used to evaluate an e-government system developed by the Ministry of Trade of the Republic of Indonesia, called Inatrade. The results of Inatrade system evaluation using IPA method show that information completeness, fulfillment, responsiveness and contact are the dimensions that need to be given priority in the improvement process of Inatrade system

The Application of a Decision-making Approach Based on Fuzzy ANP and TOPSIS for Selecting a Strategic Supplier

Supplier selection becomes very important when used in the context of strategic partnerships because of the long-term orientation of the relationship. This paper describes the application of a decision-making approach for selecting a strategic partner (supplier). The approach starts with defining a set of criteria that fits the company's condition. In the next steps, a combination of fuzzy-ANP and TOPSIS methods is used to determine the weight for each criterion and rank all the alternatives. The application of the approach in an Indonesian manufacturing company showed that the three factors that got the highest weight were “geographical location”, “current operating performance”, and “reliability”. Geographical location got the highest weight because it affects many other factors such as reaction to changes in demand, after-sales service, and delivery lead-time. Application of the approach helps decision-makers to gain effectiveness and efficiency in the decision-making process because it facilitates them to express their group's collective preferences while also providing opportunities for members to express their individual preferences. Future research can be directed at combining qualitative and quantitative criteria to develop the best criteria and methods for the selection of the best suppliers based on fuzzy ANP and TOPSIS
