An Analytic Hierarchy Process for Selection of Blockchain-Based Platform for Product Lifecycle Management

Blockchain technology has disrupted traditional business processes and hence gained significant attention and popularity in recent years. Consequently, a number of blockchain-based platforms are available today that offer vast applications across multiple sectors and industries. Implementing these blockchain-based platforms as an alternative to traditional product lifecycle management systems (PLMs) is one of the applications. However, before any platform is adopted, its nature, functionalities, and adaptability need to be clearly defined, evaluated, and verified. In this context, the proposed work explores the available blockchain-based platforms that can be used for the purpose of product lifecycle management. We then apply one of the multi-criteria decision-making techniques, i.e., the analytic hierarchy process (AHP), to select the best possible blockchain-based platform for PLM. As transaction speed, data privacy, and scalability are our prime concerns in PLM, we only considered the permissioned (private) blockchain platforms as available alternatives in the final selection process. Results achieved on the basis of considered criteria show that Hyperledger Fabric is the top-ranked among available alternatives to be used for PLM. Furthermore, as blockchain is a new technology, a clear comparison of the available platforms based on the performance-based metrics and key performance indicators is not completely matured and is still in the development stage. However, our proposed approach can be considered an attempt to create a procedure for evaluating blockchain-based platform implementation in any sector.

Application of the Analytic Hierarchy Process for selection of alternative solutions for domestic wastewater treatment

Choosing the best form of domestic sewage treatment requires analyses that allow decision-making on the ideal solutions for implementation, according to the particularities of each regionality, especially when it comes to rural and isolated areas dependent on decentralized solutions. Thus, through this study, the Analytic Hierarchy Process (AHP) was used from a data collection on simplified treatment systems existing in temperate municipalities without a dry season, to evaluate priority systems in different scenarios considering environmental, social, and technical-economic indicators. Among the results for the scenarios performed, the compact upflow anaerobic reactor, the septic tank and anaerobic filter, and the septic tank and built-in flooded system of vertical subsurface flow were the solutions that proved to be the most indicated following the indicators used and the existing information. It is noteworthy that the results refer to the study area in question, and new applications of the method are needed in different climatic regions. From the application of the methodology, the AHP tool indicated that it is a viable method to assist in decision-making regarding the selection of sewage treatment systems in rural areas, which, being tied to municipal planning in basic sanitation, assists in the optimization of existing resources. The sensitivity of the method showed the importance of its application with data collected on site, in addition to the incorporation of public and experts opinions in the contribution of the degree of importance of the criteria and indicators used.

An Application of Analytical Hierarchy Process in Selection of Coating Material Composition in Lost Foam Casting Process

In modern industrial era, the dimensional accuracy and surface finish are two major criteria in the selection of casting process. To achieve this paradise, lost foam casting is one of the casting processes. In this casting process, the shell is made by removal of expandable polystyrene or foam pattern with the application of heat. During the foam decomposition process, many problems have been generated such as bending, expansion, distending and crack of the shell. These problems may be eliminated by selecting the optimum ratio of coating materials. In this research work, zircon and aluminium silicate refractory coating materials with sodium silicate binder have been used with different composition and prepared the four test samples from them. For selection of best shell material composition, analytical hierarchy process is used.

The analytic hierarchy process for selection of suitable trees for Mexico City

Urban foresters require methodologies that help to select tree species for urban environments, mainly in places where there is a large number of potential species such as the Valley of Mexico. We applied the Analytic Hierarchy Process (AHP) to select suitable native tree species that are under-represented or non-existent in Mexico City trees. Through bibliographic research, the selection criteria and the list of trees to be evaluated were selected; later, a group of specialists in urban forestry and arboriculture determined by pair-wise comparison matrices the specific weight of each selection criterion, while a set of taxonomists evaluated the rating of each attribute for each species. Finally, for practical purposes, the synthesis of both evaluations resulted in a ranking of 15 tree species according to their degree of aptitude suggested for Mexico City. According to results, Buddleja cordata, Quercus glaucoides and Litsea glaucescens obtained the highest degree of suitability as a large, medium and small-size species, respectively. The AHP proved to be an appropriate methodology to solve a complex problem through multiple criteria evaluation by diverse specialists in the subject. The implementation of the results contributes to the selection process of suitable tree species for urban environments.

Application of Risk-Based Maintenance Using Analytic Hierarchy Process for Selection of Maintenance Policy of Dragline

This paper proposes an approach to select the optimum maintenance policy for mining equipment using risk-based maintenance (RBM). RBM constitutes the process of risk assessment that identifies high-risk components of equipment, and analytic hierarchy process (AHP) that helps selecting an optimum maintenance policy for individual components. By applying RBM, three high-risk components of dragline such as reduction gearbox, bearing, and motor pinion shaft have been identified,and then AHP was used on these three components by considering four criteria, eight sub-criteria and four alternative maintenance policies (such as periodic, preventive, predictive and corrective maintenance). Local and global scores for these three components were calculated from the opinion of three experts of the case study mine. AHP global scores revealed that the optimum maintenance policy for reduction gearbox and motor pinion shaft was preventive maintenance, whereas for bearing it was periodic maintenance policy. Adoption of such maintenance planning is expected to reduce maintenance cost and downtime of the dragline.

Application of analytic hierarchy process for selection of heat transfer meters

At the present time, the process of super-viscous oil deposits development is of current interest among the oil companies. The production of super-viscous oil in the Republic of Tatarstan is carried out using the steam-assisted gravity method. The article proposes a method for solving the problem of selecting a heat meter devices on sites of the Ashalchi field for the production of super-viscous oil. Analytic hierarchy process was used and the parameters required for the optimal selection of heat meters have been determined in the course of investigations. Based on these parameters, a hierarchy for the heat metering unit and a pairwise comparison matrix for the main criteria of the flowmeters have been made. As a result of the analysis, the optimal flowmeter in terms of the chosen criteria has been selected.

An analytical hierarchy process for selection of the optimal procedure for resveratrol determination in wine samples

The study shows the application of analytical hierarchy process (AHP) in ranking the analytical procedures, that are applied for resveratrol determination in wine samples. 19 different analytical methodologies are described by metrological, economic and environmental criteria, that are further divided into 10 subcriteria. Before AHP application, the amount of input data is decreased with cluster analysis. The first run of AHP is aimed to rank the clustered analytical procedures, while the second analysis is performed to select the best procedure from the cluster with the highest rank obtained in the first AHP run. The procedure based on a direct sample injection to high performance liquid chromatography with UV detection is the most beneficial one. AHP is excellent tool for the assessment and the selection of the most appropriate analytical procedure from several available. The choice of MCDA method is dictated by the fact, that so far, no examples of the usage of a given method for the selection of the optimal analytical procedure have been found in the literature.

Application of the Fuzzy AHP in Selection of Most Appropriate Construction Method for Tuti - Bahri Bridge

In presence of many kilometers of waterways and valleys in Khartoum State, bridges had become desperately needed for proper communication and development. There were many types of bridges in Sudan made of concrete and/or steel using various types of suspended, steel truss, arch and cable-stayed bridges which were constructed by different methods. The successes in bridge projects will be reached if the project achieved quality, cost saving and completed in optimum time schedule. Therefore, selecting appropriate bridge construction method is essential for the success of bridge construction projects. The Analytical Hierarchy Process (AHP) method has been widely used for solving multi-criteria decision-making problems. The Authors applied Fuzzy AHP, similar to the process suggested by Nang in 2008, to select the most appropriate construction method to be adopted for the Cable-stayed Tuti-Bahri Bridge Project which the Ministry of Infrastructures and Transportation of Khartoum State intends to construct at Khartoum city-center. The results were successfully applied for selection of the most appropriate bridge superstructure construction method among two methods. The hierarchy of the alternatives is suggested based on opinion of two Sudanese experts through questionnaires to obtain the basic criteria. Weights, from group of evaluations, are analyzed using excel spread sheets developed by the Authors. Applying Nang’s approach revealed logical procedure for selection of construction method that best suits Tuti-Bahri Bridge.

Underground coal mine layout selection using analytical hierarchy process

One of the most critical and complicated steps in mine planning is the selection of a suitable layout based on geological, geographical, geotechnical and economical parameters. These parameters influence the choice of different layouts of coal mine workings and normally examined on the basis of experience gained in the coalfields. The wide ranging combinations of geological, geotechnical and mining conditions make the selection of the optimum design and layout for a particular situation a difficult task. Variations in these parameters result in multiple feasible mine layouts; where each layout entails some inherent problems and the optimal layout is the one that offers the least problems. These variations in designs result in complex multi-decision situations that cannot be solved by a simple technique. This study applies the analytical hierarchy process in selection of the most viable panel orientation for a longwall operation. A back analysis of this technique was conducted at a mine located in Central Queensland, Australia. The geological and geotechnical aspects of the mine resulted in variations in the recommended panel orientations. Three different mine layouts with variable geological and geotechnical impacts were evaluated and the optimum mine layout was determined. This study also challenged the viability of the results obtained by performing a consistency check at every critical stage of the project.

Analytic Hierarchy Process for Selection of Erp Software for Manufacturing Companies

Enterprise Resource Planning (ERP) systems are popular as an IT enabled tool, which integrates different functional areas of business. ERP systems are implemented as a total business solution that supports major functionalities of business. However, many of the implementations are not success stories. Most post implementation problems are due to the inappropriate selection of systems. This paper describes multi-criteria decision model using Analytic Hierarchy Process for the selection of ERP systems for manufacturing companies. First, ERP evaluation criteria are developed by using past literature and through a questionnaire distributed among Sri Lankan manufacturing companies. Seven major criteria are identified and under each criterion several sub-criteria are identified. Selection of the best suited ERP system leads to a multi-criteria decision making problem as ERP systems should be evaluated based upon many criteria. Using the identified main and sub criteria, an Analytic Hierarchy Process (AHP) model is developed for ranking the ERP software. An example of a case is presented to show the actual implementation of AHP model. Expert Choice software is used to solve this AHP model.
