“…Selain itu, masalah seperti terjadinya overrun pada anggaran dan final account, konsumsi material yang terlampau besar dan masalah-masalah lainnya, sangat berpengaruh terhadap keakuratan suatu anggaran biaya (Fan dan Guo, 2022). Terdapat beberapa metode pengendalian biaya secara tradisional yang dapat diterapkan pada proyek, seperti menerapkan prinsip nilai yang diperoleh (earned value), membandingkan biaya dan waktu pelaksanaan aktual dengan yang direncanakan, dan lain-lain (Chatterjee et al, 2020). Akan tetapi, metode-metode tersebut tidak dapat secara efektif mengontrol proses anggaran konstruksi aktual dalam proyek yang sebenarnya.…”

Manajemen dan pengendalian biaya memiliki dampak yang besar dalam berbagai jenis proyek pembangunan. Penganggaran biaya teknik (engineering cost budgeting) sangat penting untuk mewujudkan industri teknik dan konstruksi yang sehat. Namun, ketika mempersiapkan estimasi anggaran untuk proyek, banyak terdapat “ketidakpastian” dan “perkiraan-perkiraan” yang terjadi. Untuk memecahkan masalah tersebut, BIM dapat digunakan sebagai salah satu solusinya. Makalah ini membahas tren dan tinjauan mengenai pemanfaatan BIM untuk anggaran biaya proyek konstruksi. Pemetaan data bibliometrik dilakukan dengan menggunakan perangkat lunak VOSViewer. Data bibliografi sebanyak 150 catatan ilmiah diperoleh melalui database Scopus dengan rentang waktu dari tahun 2008 hingga 2023. Hasil penelitian menunjukkan bahwa pertumbuhan publikasi tertinggi terjadi pada tahun 2019 yang mencapai 36 publikasi (18,67%). Negara dengan artikel publikasi terbanyak adalah Amerika Serikat, yaitu sebanyak 29 dokumen. Berdasarkan tinjauan dari artikel-artikel yang terkumpul, diketahui bahwa estimasi anggaran biaya dengan metode konvensional membutuhkan waktu yang lama dan berpotensi lebih besar menimbulkan terjadinya kesalahan. Penggunaan BIM dalam estimasi anggaran biaya, berpotensi mengurangi timbulnya pembengkakan biaya akibat perubahan ruang lingkup atau pekerjaan ulang. Selain itu, pemanfaatan BIM dapat mengurangi terjadinya kesalahan pada anggaran biaya yang dihasilkan, hal ini dibuktikan melalui verifikasi kasus yang menemukan bahwa dengan penggunaan BIM deviasi anggaran berkurang sekitar 78% dibandingkan dengan metode konvensional.

“…If a team decides to stop testing in a short period, the client may receive unreliable software . As a result, determining the appropriate time to deploy the software [14] is critical. Furthermore, researchers have offered the notion of incorporating an effort function into an NHPP model to improve results on the software fault phenomena [8].…”

A software release schedule has been explored in this paper based on cost and reliability considerations using a change point paradigm. The goal of this study is to model the uncertainties that are present in the estimated model parameters. First, the LSE technique has been used to estimate unknown model parameters and then, by using Triangular Fuzzy Numbers (TFNs), fuzzification of the parameters has been done. As software testing is done by humans, and their behaviour is subjective, the notions of fuzzy set theory is extremely valuable in developing SRGMs. Finally, the predicted total software cost and fuzzy reliability growth are calculated. Using software testing data from real-world applications at different levels of uncertainty, the performance of the proposed model is illustrated. The computed results indicate that the proposed model produces a realistically more accurate insight of reliability metrics, specifically software reliability and total software cost in a fuzzy environment.

“…However, the testing efforts spent in the actual testing process, the skill level of testers and various testing tools will affect the fault and reliability of the software in an unpredictable way, resulting in a certain random impact on the detection rate of each fault, which may produce irregular fluctuations. Aim at the influence brought by these uncertain factors, some scholars solve the problem by adding noise term into b(t) [3,4,14,23,26]; Other scholars build a data-driven reliability model [5,13,22] based on the data itself. This kind of model can interpret and analyze the fault data very well, but it can't establish a specific mathematical model analytic formula, which makes it difficult for managers to adjust and analyze the software fault later.…”

In reality, sudden updates of software, attacks of hackers, influence of the Internet market, etc. can cause a surge in the number of open-source software (OSS) faults (this moment is the time when impulse occurs), which results in impulsive phenomenon. For the existing software reliability models, dynamic process of software fault is considered to be continuous when assessing reliability, but continuity of the process can be disrupted with appearance of random impulses. Thus, to more accurately assess software reliability, we proposed an OSS reliability model with SIDE. In the model, dynamic process of software fault is divided into a continuous and a skipped part, described the continuous part of the process with SDE, and described destruction of the continuity caused by unpredictable random events with random impulses. Finally, the proposed model is verified with two datasets from real OSS project, and the results show that the proposed model is more in line with reality and has better fitting effect than the existing models.
