Functional Block Diagrams and automated construction of event trees
Reliability Engineering & System Safety, 1998Co-Authors: Ioannis A. PapazoglouAbstract:Abstract Functional Block Diagrams are introduced as graphical representations of the function of a system. A Functional Block provides the output of a system as the outcome of a joint event defined by the inputs to the system and its various states. Functional Blocks corresponding to different subsystems are combined together to form a Functional Block Diagram representing the Functional characteristics of the combined system. Conversely, a complex system represented by a single Functional Block is decomposed to constituent components with a corresponding Functional Block Diagram. It is demonstrated that a Functional Block Diagram is an alternative representation of an event-tree corresponding to the outcome space of the underlying joint event. The concept of output space partition is introduced and an algorithm is developed for generating the most compact form of the event-tree consistent with a given partition. This algorithm forms the basis of a technique for the automated construction of an event-tree starting from a developed Functional Block Diagram. This technique is amenable to computerization. Finally, as a demonstration of the technique, the event-trees of a boiling water reactor (BWR) are developed.

PENGENDALIAN MODUL STORAGE STATION BERBASIS SEQUENTIAL FUNCTION CHART
2017Co-Authors: Budhi Lamtoro, Didi Widya Utama, Gatot SoeharsonoAbstract:Abstrak: Otomasi industri merupakan hal yang tidak bisa dihindari untuk meningkatkan produktifitas, kualitas dan keselamatan. Oleh karena itu, simulasi mesin otomasi sangatlah penting untuk dibuat agar sistem kerjanya dapat diketahui secara pasti dan dapat dipastikan aman bagi operator. Proses yang biasa digantikan dengan otomasi adalah proses pemindahan barang dan proses pengecekan, sehingga sudah tidak membutuhkan tenaga manual lagi. Modul Storage Station adalah bagian dari mesin simulasi untuk pengecekan. Dibutuhkan PLC untuk mengontrol kedua modul tersebut sehingga dapat berjalan sesuai dengan yang diinginkan. Salah satu bahasa pemrograman yang mudah dimengerti adalah Functional Block Diagram (FBD). Pada FBD, terdapat sebuah metode yaitu metode Sequential Function Chart (SFC) untuk mengatur urutan kerja dari program. Penelitian ini membahas mengenai pengendalian modul Storage Station yang menggunakan bahasa pemrograman FBD dengan menggunakan metode SFC. Hasil yang didapatkan adalah mesin simulasi untuk modul Storage Station dalam skala laboratorium yang mampu mendeteksi material, warna, dan lubang dari benda kerja beserta Diagram gerakan dari masing-masing modul.

pengendalian modul overhead handling station berbasis sequential function chart
POROS, 2017Co-Authors: Winwin Winwin, Gatot Soeharsono, Agus HalimAbstract:Abstrak : Penelitian ini berisi hasil pengujian dan simulasi pada stasiun penanganan overhead dimana stasiun berada dalam otomasi sistem distribusi. Tujuan dari penelitian ini adalah untuk membuat suatu program di bidang komputasi dan overhead handling station agar berjalan bila dikombinasikan dengan program yang sesuai yang telah dibuat. Modul stasiun penanganan overhead ini adalah bagian dari mesin otomasi yang mendistribusikan simulasi proses objek berongga dan tidak berongga, maka PLC harus mengendalikan semua sistem modul stasiun penanganan overhead yang sesuai dengan sistem yang Anda inginkan. Untuk mengendalikan sistem kerja, bahasa pemrograman yang mudah dipahami sangat dibutuhkan seperti Functional Block Diagram (FBD) dimana Diagram blok fungsional adalah metode yang dapat menggambarkan fungsi antara variabel input dan output. Dalam FBD ada metode bagan fungsi sekuensial (SFC) yang mengendalikan aktivitas sekuensial program. Jadi penelitian ini membahas tentang pengendalian modul pengolahan yang menggunakan bahasa pemrograman FBD dengan menggunakan metode SFC.

SISTEM OTOMASI PADA MODUL PROCESSING DENGAN MENGGUNAKAN SEQUENTIAL Functional CHART
POROS, 2017Co-Authors: Moergen Tandinata, Didi Widya Utama, Gatot SoeharsonoAbstract:Abstract: Automation is a technology that can be used to implement an instructional process or an automatic procedure. In this framework that has been using an instructional program that combined with a control system to process an instruction or commands. This processing module is a part of the automation which checking a process simulation of hollow and not hollow objects, then a PLC is use to control the process as designed be needed to control all of the working processing modules systems works. working system, a programming language that easily to be understood is needed such as Functional Block Diagram (FBD) is use to program a plc system which Functional Block Diagram (FBD) is a method that can describe a function between input and output variable, in FBD there is a Sequential Function Chart method (SFC ) which control the program sequential activity. So this research discusses the control of processing module which based on FBD programming language by using the SFC method.

Computer-assisted fault-tree construction using a knowledge-based approach
IEEE Transactions on Reliability, 1994Co-Authors: M.s. ElliottAbstract:This paper presents a knowledge-based approach to analyzing fault trees of engineering systems. This approach can be used to build a fault tree from a graphical Functional Block Diagram (using reduction for replicated events), to compute minimal cut sets, and to analyze the system for redesign suggestions. An implementation of this approach in a rule-based language is presented. The results are compared with manually prepared reliability reports on an electrical power system and an hydraulic system. The knowledge-based system outperforms the manual procedure in timeliness and accuracy. >

Adaptive Control System of Transport Wheels Electromechanical Braking
International Review of Automatic Control (IREACO), 2014Co-Authors: Victor V. Putov, Victor N. Sheludko, Anton V. Putov, Anastasiia D. StotckaiaAbstract:The development of the controlled electromechanical braking devices for transport wheel is discussed. The generalized Functional Block Diagram of an electromechanical braking device is described. The mathematical model describing dynamic behavior of the braking transport wheel with pneumatic tires and electromechanical engine is given in detail. On the basis of the developed mathematical model a system of direct adaptive control of the braking mode transport wheels is build. Control law at the same time suppresses the effect of elastic deformation. Some results of efficacy studies of adaptive control system constructed are also given.
