Modelling uncertainty and gross errors in preliminary design of buildings

Parameter ratios are important information for the ship designer in the preliminary design stages. They can be used as a tool to identify the main parameter of vessel and their other technical characteristics. The information about parameter ratios of mono-hull vessel is currently available in Naval Architecture literatures, but it is not the case for the type of twin-hull vessel called catamaran. Having conducted technical analysis in this research, it has been identified that parameter ratios of passenger catamaran vessel made of FRP has values of L / B ratio from 2.52 up to 3.7, L / D ratio from 5.25 up to 11:24, slenderness ratio (Lwl/BwL) from 9 up to 12. Other values of various parameter ratios like B/T, D/T, L /√ L, and Displacement/L are also discussed.

Bantu Hidro-Oceanography (BHO) adalah salah satu satuan bantu dalam bidang survei Hidro-Oceanography yang termasuk dalam susunan tempur pendukung (Supporting Force). Untuk kepentingan tersebut maka preliminary design kapal Hidro-Oceanography dilaksanakan sebagai langkah awal dalam perencanaan dan pengadaan kapal Hidro-Oceanography untuk mengkaji karakteristik umum desain yaitu hidrostatik dan stabilitas sehingga aspek kelayakan kapal dapat terpenuhi. Analisa hasil kajian kinerja kapal Hidro-Oceanography dipersiapkan untuk pengujian tahanan/resistance model kapal.Keywords : Preliminary design1, Hydrostatic2, Stability3

The article discusses the process of designing the running system of a rail vehicle using CAD and CAM tools as the solutions supporting the process. It describes the particular stages of design taking its final shape: from a preliminary design, through a detailed design, ending with the stage of production. Each stage includes a presentation of how CAD and CAM tools are used to support design engineers in their practice. Keywords: running system, design, CAD, CAM
