Abstract

Similarity calculation between business process models has an important role in managing repository of business process model. One of its uses is to facilitate the searching process of models in the repository. Business process similarity is closely related to semantic string similarity. Semantic string similarity is usually performed by utilizing a lexical database such as WordNet to find the semantic meaning of the word. The activity name of the business process uses terms that specifically related to the business field. However, most of the terms in business domain are not available in WordNet. This case would decrease the semantic analysis quality of business process model. Therefore, this study would try to improve semantic analysis of business process model. We present a new lexical database called B-BabelNet. B-BabelNet is a lexical database built by using the same method in BabelNet. We attempt to map the Wikipedia page to WordNet database but only focus on the word related to the domain of business. Also, to enrich the vocabulary in the business domain, we also use terms in the business-specific online dictionary (businessdictionary.com). We utilize this database to do word sense disambiguation process on business process model activity’s terms. The result from this study shows that the database can increase the accuracy of the word sense disambiguation process especially in particular terms related to the business and industrial domains.

Abstract

The purpose of this paper was to discover an anomalous-free business process model from event logs. The process discovery was conducted using a graph database, specifically using Neo4J tool involving trace clustering and data filtering processes. We also developed a control-flow pattern to address, AND relation between activities named parallel business process. The result showed that the proposed method improved the precision value of the generated business process model from 0.64 to 0.81 compared to the existing algorithm. The better outcome is constructed by applying trace clustering and data filtering to remove the anomaly on the event log as well as discovering parallel (AND) relation between activities.

Abstract

Business processes are implemented in an organization. When a business process is run, it generates event log. One type of event log is double timestamp event log. Double timestamp has the start and complete time of each activity executed in the business process and has a close relationship with temporal pattern. In this paper, seven types of temporal pattern between activities were presented as extended version of relations used in the double timestamp event log. Since the event log was not always executed in sequential way, therefore using temporal pattern, event log was divided into several small groups to mine the business process both sequential and parallel. Both temporal pattern and Time-based α+ Miner algorithm were used to mine process model, determined sequential and parallel relations and then evaluated the process model using fitness value. This paper was focused on the advantages of temporal pattern implemented in Time-based α+ Miner algorithm to mine business process. The results also clearly stated that the proposed method could present better result rather than that of original α+ Miner algorithm.

Abstract

As a company engaged in the distribution of wireless devices, Return Material Authorization (RMA) is a mandatory service that must be owned by the company. RMA is a part of the process of returning a product to receive a refund, replacement, or repair during the product’s warranty period. The business process of RMA used functionally design, which is not considered to be effective in terms of time and cost for the company of 2880 minutes for IDR 348242. In this research, Project Evaluation and Review Technique (PERT) was used to select the optimal traces; to optimize time and cost, the researcher used goal programming. This technique allows the creation of a controlled and orderly activity because the schedule and budget of a job are predetermined prior to the implementation. The optimization results show that the process time is reduced by 50% and the cost is reduced by almost 55% which show improvement on the performance of the business processes.

Abstract

The quality of information systems affects the company's business performance. Therefore, it is necessary to analyze business processes to determine any discrepancies between the planned business processes and the actual ones. Based on the results of this analysis, the business process can be improved. The fundamental factor of manufacturing companies is production process. In reality, there are many discrepancies between the actual business processes with the pre-planned, so that there should be analyzed. The analysis can be performed by modeling the business process using Coloured Petri Nets (CPN). In this study, the objectives are to determine the level of conformance checking of business processes, reachability graph and the bottleneck analysis. The results of the analysis are used to construct a recommended model. Based on the analysis of the case study, e.g. a steel industry in Indonesia, the recommended model has a better value than initial model.

Abstract

The misuse of health data stored in the Electronic Health Record (EHR) system can be uncontrolled. For example, mishandling of privacy and data security related to Corona Virus Disease-19 (COVID-19), containing patient diagnosis and vaccine certificate in Indonesia. We propose a system framework design by utilizing the InterPlanetary File System (IPFS) and Blockchain technology to overcome this problem. The IPFS environment supports a large data storage with a distributed network powered by Ethereum blockchain. The combination of this technology allows data stored in the EHR to be secure and available at any time. All data are secured with a blockchain cryptographic algorithm and can only be accessed using a user's private key. System testing evaluates the mechanism and process of storing and accessing data from 346 computers connected to the IPFS network and Blockchain by considering several parameters, such as gas unit, CPU load, network latency, and bandwidth used. The obtained results show that 135205 gas units are used in each transaction based on the tests. The average execution speed ranges from 12.98 to 14.08 GHz, 26 KB/s is used for incoming, and 4 KB/s is for outgoing bandwidth. Our contribution is in designing a blockchain-based decentralized EHR system by maximizing the use of private keys as an access right to maintain the integrity of COVID-19 diagnosis and certificate data. We also provide alternative storage using a distributed IPFS to maintain data availability at all times as a solution to the problem of traditional cloud storage, which often ignores data availability. Doi: 10.28991/esj-2021-SP1-013 Full Text: PDF

Abstract

Tantangan ketika sebuah perusahaan akan berpindah menggunakan sistem ERP adalah adanya ketakutan untuk menyediakan infrastruktur beserta kebutuhan lainnya. Dengan menggunakan cloud computing, perusahaan tidak perlu untuk menyediakan infrastruktur, konfigurasi perangkat lunak dan pemeliharaannya, akan tetapi hanya tinggal menggunakannya langsung sebagai suatu layanan yang dapat diakses melalui berbagai media seperti komputer desktop, laptop, mobile device selama terkoneksi dalam jaringan internet. Sistem ERP  yang dibangun menerapkan prinsip multi tenant pada cloud computing. Implementasi prinsip multi tenant dilakukan dengan pendekatan basis data terpisah (separated database). Dengan prinsip ini, satu perangkat lunak, akan mengakses banyak sekali basis data, sehingga data antara satu perusahaan, dengan perusahaan lain, tidak akan saling tercampur dan lebih memiliki tingkat integritas yang tinggi. Selain itu, perangkat lunak yang dibangun menyediakan beberapa konfigurasi yang dapat digunakan apabila suatu perusahaan ternyata memiliki proses bisnis yang berbeda. Dengan penerapan sistem ini, kekhawatiran perusahaan mengenai infrastruktur dan pemeliharaan sistem dapat diatasi sehingga tujuan penerapan ERP sebagai langkah mempermudah proses bisnis perusahaan dapat tercapai.

Abstract

Process discovery adalah teknik penggalian model proses dari rangkaian aktivitas yang tercatat dalam event log. Saat ini, sistem informasi menghasilkan streaming event log dimana Online Heuristic Miner adalah algoritma process discovery yang mampu menghasilkan model proses dari streaming event log. Algoritma Online Heuristic Miner memiliki kelemahan yaitu ketidakmampuan mengatasi incomplete trace. Incomplete trace adalah rangkaian aktivitas pada event log yang terpotong di bagian awal ataupun di bagian akhir. Incomplete trace mengakibatkan proses tidak dapat ditampilkan secara utuh dalam model proses. Algoritma yang memanfaatkan Model Markov Tersembunyi digunakan untuk membentuk model proses yang dapat menangani incomplete trace. Algoritma yang memanfaatkan Model Markov Tersembunyi terdiri atas gabungan dari metode pembentukan model proses serta metode yang dimodifikasi. Metode yang dimodifikasi adalah metode Baum- Welch, Backward serta Viterbi. Metode Backward dan Viterbi yang dimodifikasi digunakan untuk memperbaiki incomplete trace sedangkan metode Baum-Welch yang dimodifikasi dan metode pembentukan model proses digunakan untuk membangun model proses dari Model Markov Tersembunyi. Hasil uji coba menunjukkan bahwa dengan adanya perbaikan incomplete trace, nilai kualitas dari sisi fitness, presisi, generalisasi, dan simplicity model proses dari algoritma yang memanfaatkan Model Markov Tersembunyi lebih tinggi dibandingkan model proses dari algoritma Online Heuristic Miner.
