This paper addresses the design of an assembly system facility consisting of multiple assembly lines of different shapes. In such a design problem there are two conflicting objectives: (i) to minimize the overall area of the facility; and (ii) to maximize the efficiency of the material handling transportation system. We first address the optimization problem of objective (ii) when replacing obj...

The Korean government has strived to secure a disposal site for the safe management of radioactive waste since the early 1980s. The 249 th meeting of the Atomic Energy Commission (AEC) held in September 1998 established the “National Radioactive Waste Management Policy”, which aims at completing the construction of a Low and Intermediate Level Radioactive Waste (LILW) disposal facility by 2008,...

scale transmission loss facility for flat lightweight panels. Abstract: The design, construction and qualification of a small-scale sound transmission loss (STL) facility are described. STL measurements were made using the sound intensity technique based on ASTM E 2249-02 [1]. The volume of the irregular-shaped reverberant source chamber was 15 m 3 , and the volume of the regular-shaped anechoi...

The construction of the Project for High-intensity Proton Accelerator Facility(Figure 1). in Japan has been started this year. The Japan Hadron Facility of KEK1 and the Neutron Science Project of JAERI2 merged to this project. The purpose of this Joint Project is to pursue frontier science in particle physics, nuclear physics, materials science, life science and nuclear technology. Accelerators...

The accurate co-alignment of the transmitter to the receiver of the BepiColombo Laser Altimeter is a challenging task for which an original alignment concept had to be developed. We present here the design, construction and testing of a large collimator facility built to fulfill the tight alignment requirements. We describe in detail the solution found to attenuate the high energy of the instru...

SUMMARY: Construction projects involve a large number of both direct stakeholders (clients, professional teams, contractors, etc.) and indirect stakeholders (local authorities, residents, workers, etc.). Current methods of communicating building design information can lead to several types of difficulties (e.g. incomplete understanding of the planned construction, functional inefficiencies, ina...

The National Science Foundation has recently approved funding for LENS (the low energy neutron source) at Indiana University and construction of this facility has begun. LENS represents a new paradigm for economically introducing neutron scattering into a university or industrial setting. In this design, neutrons are produced in a long-pulse (1 ms) mode through (p,n) reactions on a water-cooled...

The main objective of this paper is to identify the design criteria for a BIM Education Resilient System STEM program. The curriculum’s development will semantically relate to resilience concepts with Systems Engineering and Building Information Modeling (BIM) practices and standards. The Sustainable Facilities and Infrastructure in Constrained Environments’ (SuFICE) in advancing STEM to Suppor...
