"The book discusses delay-time modelling for multi-unit technical systems in various reliability structures, examining the optimum maintenance policies both analytically and practically, focusing on a delay-time modelling technique that has been employed by researchers in the field of maintenance engineering to model inspection intervals. It organizes the existing work into several fields, based mainly on the classification of single- and multi-unit models and assesses the applicability of the reviewed works and maintenance models. Lastly, it identifies potential future research directions and suggests research agendas."

"ABSTRAKTujuan utama dari penelitian adalah untuk mengidentifikasi komponen yang paling kritis atau paling lemah berbasis analisis RAMD. Peningkatan kinerja komponen akan dilakukan pada komponen terlemah yang ditemukan. Data time-between-failure (TBF) dan time-to-repair (TTR) dikumpulkan untuk memperkirakan reliability, availability, maintainability, dependability, dan mean-time between hazardous failure (MTBH). Berbagai ukuran kinerja pabrik seperti mean-time-to-repair (MTTR) dan mean-time-between-failure (MTBF) juga dipaparkan dalam penelitian. Permodelan kinerja sistem didasarkan pada asumsi bahwa data perbaikan dan kegagalan adalah bersifat konstan dan independen secara statistik. Untuk merepresentasikan penerapan metode yang diusulkan, Lini Produksi NPK, Water Treatment Plant dan cooling tower digunakan sebagai objek penelitian untuk studi kasus evaluasi dan peningkatan kinerja sistem. Data kegagalan dan data perbaikan dapat menjadi basis data yang berguna bagi manajemen untuk meningkatkan availability dari sistem.

ABSTRACTThe main objective of this study is to identify the most critical or weakest components based on RAMD analysis. System performance and Improvement will be performed on the most critical component. Time-between-failure (TBF) and time-to-repair (TTR) data are collected to estimate reliability, availability, maintainability, dependability, and mean-time between hazardous failures (MTBH). The dependability parameters are solely applied to those subsystems that have both constant failure rate and repair rate. Various measures of plant performance such as MTTR and MTBF are as well presented. Performance modeling of the system is carried out based on the assumption that both repair and failure data are statistically independent. To show the application of the proposed method, NPK fertilizer production line, Water Treatment Plant and Cooling Tower System as repairable production system has been provided for case studies of performance evaluation. The records of failure and repair data can be a useful database for the management of to improve system availability."

"Maintenance management information systems are essential to ensure control, gain knowledge and improve-decision making in companies dealing with network infrastructure, such as distribution of gas, water, electricity and telecommunications. Divided into three major sections, maintenance management in network utilities defines a series of stages which can be followed to manage maintenance frameworks properly. Different case studies provide detailed descriptions which illustrate the experience in real company situations. An introduction to the concepts is followed by main sections including :- A literature review : covering the basic concepts and models needed for framework design, development and implementation.- Framework design and definition : developing the basic pillars of network utilities maintenance management framework.- Performance evaluation & maturity : focusing on the reliability concept and maturity models from different viewpoints."

"Telah dibuat suatu rancang bangun sistem mekanik alat pembuat jalur sobekan kertas dan cacahnya. Sistem ini dirancang dengan tujuan untuk mempermudah dalam pengerjaan finishing percetakan, apalagi untuk perusahaan percetakan kecil dan menengah, karena tidak perlu memerlukan biaya lebih besar untuk membeli alat yang besarnya. Dengan adanya sistem mekanik ini dapat mempermudah dan mendukung dalam sistem kontrol untuk otomatisasinya, karena dalam sistem mekanik tersebut terdapat peletakan sensor sensor yang biasa digunakan sebagai logika untuk sistem kontrolnya. Sistem mekanik ini terdiri dari plat besi, as, motor dc, motor ac dua arah, solenoid, roda karet, belt konveyor, pisau potong yang bermata khusus, dudukan sensor dll. Dengan demikian sistem mekanik ini tidak merupakan untuk simulasi lagi melainkan alat yang memang sudah dapat diterapkan dalam keadaan realnya, hal ini dikarenakan ukuran alat ini disesuaikan dengan area kertas yang biasa digunakan dalam percetakan, dengan batasan sampai ukuran kertas folio. Pada sistem ini digunakan mekanik untuk pergerakan dudukan sensor letak jalur sobekannya, sehingga dengan demikian letak jalur sobekannya tidak pada satu tempat saja melainkan dapat diatur sesuai yang diinginkan.

Was made by an designing to develop its count and paper rip band maker appliance mechanic system. This system is designed as a mean to water down in workmanship finishing printing office, and surely for the middle and small printing office company, because needn't cost money bigger to buy appliance which is the level of. With this mechanic system existence can water down and support in control systems for otomatisasinya, because in the mechanic system there are censor censor situating which commonly use as logic for its control systems. this Mechanic system is consisted of by the iron plate, ace, motor dc, motor ac two direction, solenoid, rubber wheel, belt conveyor, crosscut knife is which have the special eye, sensor placement etc. Thereby this mechanic system do not represent for the simulation again but the appliance which it is true have applicable in a state of the real, this matter because of size measure this appliance is adapted for by a paper area which commonly use in printing office, with definition until size measure of folio paper. At this system is used by a mechanic for movement sensor placement of rip band situation, so that thereby its rip band situation do not at one organizable just place but as wanted."

"Dalam menghadapi desain sistem yang rumit, Model-Based Systems Engineering (MBSE) direkomendasikan untuk memecahkan tantangan dari pendekatan tradisional Document-Based System Engineering (DBSE). Untuk menerapkan MBSE, diperlukan tiga pilar: bahasa pemodelan, metodologi pemodelan, dan software pemodelan. Makalah ini menyajikan Sistem Audit berbasis MBSE untuk desain Stablecoin berbasis emas yaitu proyek SCA-01. Melalui tahapan analisis kebutuhan, analisis fungsional, dan sintesis desain, desain dan pemodelan diselesaikan dengan menerapkan SysML pada arsitektur perusahaan di bawah metode Harmony-SE yang disesuaikan. Contoh proyek SCA-01 juga disediakan, beserta hasil simulasi yang dihasilkan oleh implementasinya. Terakhir, MBSE disesuaikan dengan sistem yang kompleks, alat pemodelan dan metodologi yang tepat harus dipilih untuk mengimplementasikan MBSE, dan diyakini bahwa MBSE dapat meningkatkan manajemen dan komunikasi secara efisien, sesuai dengan praktik desain MBSE yang dinyatakan dalam karya ini.

In the face of complicated system design, Model-Based Systems Engineering (MBSE) is recommended to solve the challenges of traditional Document-Based System Engineering (DBSE). To apply MBSE, three pillars are required: modeling language, methodology, and modeling tools. This paper presents an MBSE-based Audit System for Gold-backed Stablecoin conceptual design, namely the G-01 SCA project. Through the stages of requirements analysis, functional analysis, and design synthesis, the design and modeling are finished using the Capella Application under the supervision of the customized Harmony-SE methodology. An instance of the G-01 SCA changing parameter scenario generated during its implementation is also provided. Finally, MBSE is fitted to complex systems, and appropriate modeling tools and methodology should be selected for implementing MBSE. It is believed that MBSE can increase management and communication efficiency, according to the MBSE design practice stated in this work and by the result of an evaluation survey conducted for the internal team of the G-01 SCA project."
