The importance of maintenance to accelerate the production or performance of a company is now a necessity that must be run. The problem faced by Astra Daihatsu Motor is the difficulty in determining the maintenance action that must be chosen because of information delays when there are assets that are damaged, failed or failure. With the proposal using a decision tree with C4.5 algorithm can predict failures and damage that occur so that it can determine more accurate maintenance actions. Decision tree is a prediction model using tree structure or hierarchical structure. The concept of a decision tree is to transform data into decision trees and decision rules. The main benefit of using a decision tree is its ability to break down complex decision-making processes to be simpler so that decision makers will better interpret the solution of the problem. Using the decision tree method with the C4.5 algorithm can help the problems faced by Astra Daihatsu Motor in determining maintenance. This is shown from the test results of 98.20%. And it can be concluded that the application of C4.5 algorithm is able to produce asset maintenance patterns with better accuracy.","PeriodicalId":427062,"journal":{"name":"Int. J.

In this paper an investigation of this phenomena was conducted for gray cast iron (CGI). The chatter vibrations in machining process can considerably compromise the workpiece surface finish, tool wear and in some cases provide severe damage to the machine-tool. Thus there is an imminent need to expand the theory of chatter vibrations for the class of brittle materials. To analyze the vibrations of the process of machining and zones where the process is stable, and where it is unstable, the stability lobes diagram was used. This diagram is constructed at low speed cutting, where the phenomenon of damping arises. The damping is a crucial factor in the process, it increases system stability. This effect was considered in the formulation of chatter vibrations using the indentation model of Wu. For experimental validations the signals of cutting force were acquired and analysis was conducted in frequency domain to identify where the vibrations emerged allied with a roughness analysis of the workpiece. The results demonstrated perfectly the consequences of chatter vibrations in surface finish of grey cast iron and proved that the stability lobes diagram provides good results to detect these vibrations, determining the areas where the material removal should be avoid.","PeriodicalId":427062,"journal":{"name":"Int.

The revolutions were promoted and implemented to improve the efficiency and speed of productivity. However, Industry 4.0 is likely a supplementation of the existing approach, with the purpose to centralize the processes and factories together to be controlled by a central console. The goal is to procure productivity and manufacturing data to enable data analysis so that the industry’s performance affected by big data variables, namely, velocity, veracity, variety, value, and visibility are monitored and rectified for continued productivity. This research initiates the development of a theory of Industry 4.0 ROI Relativity from the economic theory of firms, incorporating the pick-and-place test equipment and Industry 4.0 variables. A case study through the experimental research approach (ERA) was conducted by measuring the effects of velocity and veracity accuracy on the good-unit per hour (UPH), profit, and return on investment (ROI) of the pick-and-place test equipment and Industry 4.0. Then, the data were analyzed with Pearson correlation coefficient to determine inter-correlations among the velocity and veracity accuracy with the UPH, profit, and ROI. This research concluded that a significant average and negative correlation exists among velocity, UPH, profit, and ROI. Furthermore, the inter-correlation analysis results show a significant average and positive correlation among veracity accuracy percentage, UPH, profit, and ROI.","PeriodicalId":427062,"journal":{"name":"Int.

In natural language processing (NLP) perspective, \"Events\" are situations, occurrences, real-world entities or facts. Extraction of events and arranging them on a timeline is helpful in various NLP application like building the summary of news articles, processing health records, and Question Answering System (QA) systems. This paper presents a framework for identifying the events and times from a given document and representing them using a graph data structure. As a result, a graph is derived to show event-time relationships in the given text. Events form the nodes in a graph, and edges represent the temporal relations among the nodes. Time of an event occurrence exists in two forms namely qualitative (like before, after, duringetc) and quantitative (exact time points/periods). To build the event-time-event structure quantitative time is normalized to qualitative form. Thus obtained temporal information is used to label the edges among the events. Data set released in the shared task EvTExtract of (Forum for Information Retrieval Extraction) FIRE 2018 conference is identified to evaluate the framework. Precision and recall are used as evaluation metrics to access the performance of the proposed framework with other methods mentioned in state of the art with 85% of accuracy and 90% of precision.","PeriodicalId":427062,"journal":{"name":"Int.
