This paper focuses on the stochastic modeling of a computer system of two identical unitsone is initially operative and other is kept as spare in cold standby. In each unit h/w and s/w components work together and fail independently. There is a single server who visits the system immediately as and when required. The server takes the unit under preventive maintenance after a maximum operation t...

Tulisan ini merupakan studi kasus yang terjadi pada boiler di Pembangkit Listrik Tenaga Uap (PLTU) Rembang setelah penulis melaksanakan magang sana. PLTU memiliki peran strategis dalam sistem kelistrikan Indonesia, karena dinilai lebih ekonomis dan hasil energi memadai. Salah satu komponen adalah boiler. Boiler alat untuk mengubah panas menjadi gerak, menggerakkan turbin agar menghasilkan listr...

conclusions it seems that, the preventive instructions are not optimally respected by ers possibly due to the crowded wards, high work load and the need to work rapidly. results cleaning blood tainted skin before phlebotomy or iv line preparation and hand washing before donning latex gloves achieved the maximum (88/150) and minimum (0/150) scores. the most observed barriers of pm were frequent ...

Nowadays, industrial necessities claims global management procedures integrating information systems in order to manage and to use the controlled-processes information and thus, to assure a good process behaviour. These aspects aim to the development of fault detection and diagnosis systems and makingdecision systems. In this work, a reference model for fault management in industrial processes ...

A maintenance problem of a linear consecutivek-out-of-n: F system with load-sharing dependent components is considered. This system consists of n components which are arranged linearly and fails if k consecutive components fail [1]. This system is commonly found in the integrated circuits, relay stations in telecommunication system, oil pipeline system, vacuum system in accelerators, and spacec...

A commonly used definition of a repairable system (Ascher and Feingold [3]) states that this is a system which, after failing to perform one or more of its functions satisfactorily, can be restored to fully satisfactory performance by any method other than replacement of the entire system. In order to cover more realistic applications, and to cover much recent literature on the subject, we need...
