  • The nesting of two-dimensional patterns onto a given raw sheet has applications in a number industries. It is a common problem often faced by designers in the shipbuilding, garment making, blanking die design, glass and wood industries. This paper presents a multi-stage layout approach for nesting two-dimensional patterns by using artificial intelligence techniques with a relatively short computation time. The raw material with irregular boundaries and internal defects which must be considered in various cases of nesting was also investigated in this study. The proposed nesting approach consists of two stages : initial layout stage and layout improvement stage. The initial layout configuration is achieved by the self-organizing assisted layout(SOAL) algorithm while in the layout improvement stage, the simulated annealing(SA) is adopted for a finer optimization.

  • The basic requirements to improve the joints quality of tube-to-tubesheet for heat exchangers are to obtain high residual contact pressures between the tubes and the tubesheet as well as low residual stresses in the transition zone of the tubes. The residual contact pressures and residual stresses which govern the joint quality are influenced by parameters such as material properties, geometric dimension of tube and tubesheet and expansion pressures. There are two types of tube layout patterns, triangular and square, which are frequently used for heat exchangers. The purpose of the present work is to examine the superior tube layout patterns considering the joints quality by comparing numerical results from sensitivity analyses which were performed for both of tube layout patterns.

  • The purpose of this study is to analyze patterns of public school building layout types, open space and relationship with communities in the Manhattan grid plan. The study illustrates how building layout patterns of school facilities are influenced by societal demands in the urban grid environment. During the nineteenth century, the Island of Manhattan was transformed into a physical representation of the Cartesian coordinate system via the development of the grid street plan. In order to take advantage of streets as urban space, it is quite important to understand characteristics of communities and open space relationships between buildings and streets. Moreover, the strategic planning of schools' outdoor space vitalizes public streets as a critical community anchor. This research reviews 118 Manhattan public schools and categorizes them by (1) building layout type, (2) site type, (3) circulation and public open space, which are the biggest factors that determine the layout patterns of the public schools in Manhattan. As a result of analysis, the layout patterns are classified into seven types : "ㅡ", "L", "ㄷ", "ㅁ", "H", "T" and "other" type. Of these, "ㅡ" type and "L" type occur most frequently, because these configurations most flexibly fit into the limited grid-locked blocks, the various types of site & topography, and adapt most dynamically to the open spaces created by using avenues and streets. The ultimate objective of this study is to provide a case study for future efforts to plan open spaces for campuses that effectively utilize the streets in proximity.

  • This study aims to explore the relationship between the spontaneous interactions of office workers and their workspace layout. The spontaneous interactions are captured by the measures regarding the 'visual interaction' between workers in their desk layouts. The measures of visual interaction then are examined by means of the office layout or desk arrangement and the properties of work patterns according to the departments, such as general affairs, sales, research and development, and planning. The study finds four types of office layout ; Type 1 with low visual interaction between workers and high intensity of visual interaction, Type 2 with high visual interaction between workers and high intensity of visual interaction, Type 3 with low visual interaction between workers and low intensity of visual interaction, and Type 4 with high visual interaction between workers and high intensity of visual interaction. The study shows that the patterns of unintentional interaction between workers varies according to the property of work and office arrangement and it also argues that the patterns of office layout are different according to properties of work.

  • Owing to generalization of design competitions since 1990s, various design methods was tried in elementary middle high school design competitions. Therefore, to analyze design characteristics of elementary middle high school is very meaningful. In this context, this study is the most important purpose for analyzing layout plans and their trends in prizewinners of elementary middle high school design competitions and for furnishing basic datum for next school design. The result of this study is following : (1) The layout patterns of school buildings are classified into 12 types. (2) Entrance design is divided into 6 types(structure, column and wall, open, half structure, general, and mixed type). (3) Square design is grouped into 7 types. (4) Pedestrian mall is sorted out 6 types(straight lineal, curve, curve and square, straight lineal and curve, and straight lineal and curve and square type). (5) Entrance types of vehicle and pedestrian are classified into 4 types(parallel, ㅡ separation, ㄱ separation, and opposite separation type) Analysis shows that the best applying for layout patterns of school buildings is ㄷ type and ㅌ type, for entrance design is structure type, for square design is ${\square}$ type and ${\bigcirc}$ type, for pedestrian mall is straight lineal and square type, and for entrance types of vehicle and pedestrian is parallel type.

  • This paper presents the use of a Genetic Algorithm to find the optimal layout for the placement of garment patterns on a fabric of fixed width to minimize fabric waste. We developed a program to simulate garment pieces and their layout on a fixed-width fabric. Each piece in the order book is placed with 2 possible orientations: 0 degrees and 180 degrees. The efficiency is measured by the length of fabric used after all the patterns in the order book have been laid out. A comparison is made between the placement using our proposed genetic algorithm to that made by an expert human using our simulation program. The results from our experiments on various pattern designs indicate that our genetic algorithm can effectively be used to obtain highly efficient solutions, comparable to that done by an expert while using a reasonable amount of time. The algorithm can also be adapted for use in other areas related to optimal consumption of sheet material such as metal, paper, and leather.

  • This paper presents a geomechanical framework for designing and optimizing layout patterns of cutterheads for rock Tunnel Boring Machines (TBMs), aiming to enhance their engineering performance. By examining the forces and moments exerted by rock, the study addresses geometric constraints associated with cutter boxes in key regions of the cutterhead, including the center, face, and gage areas, as well as the three-dimensional effects of cutterhead curvature on the geometric constraints of the back of the cutter boxes in the gage area. Novel formulas are proposed for determining the center points of cutter boxes and calculating both the minimum angular spacing and distance spacing between consecutive cutter boxes along a spiral path. The paper outlines an optimized layout design process for four cutterhead configurations: random, random paired, radial, and double spiral designs. Examples are provided to illustrate the results of applying these designs. The findings underscore the efficacy of the proposed methods in achieving a uniform and symmetrical distribution of cutters and buckets on the cutterhead surface. This approach effectively eliminates boundary overlap and minimizes unbalanced forces and moments. From a geomechanical standpoint, this framework offers a robust strategy for enhancing the performance and reliability of TBM cutterheads in rock tunneling operations.
