"The shipbuilding industry is currently operating in a state of intense market competition. In order to compete in the global market, shipbuilders must produce ships that are more efficient and which can be constructed in a relatively short turnaround time between order placement and delivery. This necessitates the development of new methods such as the building of series of ships, design optimization, and the modularization concept. This paper presents a design optimization approach based on the modularization concept for engine room design. The proposed method focuses on the following characteristics: piping systems, employed in multiple bulk carrier-series ships, of different sizes. Consideration is given to the cost and weight of these systems and the similarity and common features of the modules and arrangements concerned. The piping system design process is divided into two stages—module definition and arrangement design. A design structure matrix is adopted to define an effective module that could be employed for use in the design of various series of ships. An optimization system has been developed for use in the arrangement design stage. It uses a genetic algorithm to obtain a similar pattern for module arrangement in various series of ships, with specific consideration extended to cost and similarity. The details of the proposed method are discussed in this paper. In addition, the paper discusses the piping system design of an actual ship by using the proposed method and evaluates its effectiveness."

"Dalam men-desain sesuatu, seringkali terdapat tujuan dan kendala yang berbeda. Sangatlah sulit untuk membuat desain yang kompleks hanya dengan menggunakan kertas dan pena dikarenakan terdapat beberapa model desain yang lebih baik dimodelkan secara desain kompleks yang bersifat deskriptif, walaupun terdapat beberapa model yang dapat dengan mudah dijelaskan secara matematis. Pada skripsi ini, dijelaskan tentang metode yang berbasis Design Structure Matrix (DSM) yang digunakan untuk optimasi desain module. Skripsi ini memberikan pendekatan baru untuk desain ruang mesin menggunakan konsep modularisasi dengan konsiderasi kapal seri. Karakteristik dari metode yang diajukan ialah: memperhatikan sistem perpipaan dari kapal seri dengan ukuran yang berbeda. Lalu biaya dan bobot dari sistem perpipaan tersebut, yang terakhir dipertimbangkan kesamaan dan umum dari kapal tersebut. Dalam menghasilkan module yang efektif dan dapat digunakan pada berbagai macam kapal yang berbeda, metode design structure matrix digunakan. Modularisasi dibagi menjadi 2 poin penting: module opsional dan module umum. Dalam hal ini, algoritma secara genetic digunakan untuk menyusun module yang telah di optimasi. Dengan tambahan, tes simulasi dari desain yang telah dioptimasi dari beberapa sistem perpipaan dibahas kembali untuk mengilustrasikan prosedur dari megoptimasikan sebuah desain dan menguji keefektifan dari metodologi yang telah diajukan dalam skripsi ini"

In the maritime world now, the shipbuilding industry has been very competitive. to develop or even survive in global market competition, shipbuilders need to find methods to efficiently produce ships in order to renew energy in the shipbuilding business and stabilize shipbuilding costs. Therefore, the development of new methods like ship building modules, optimization design, and modularization concepts is necessary. This paper presents a new approach to the design of piping systems on engine room in ships based on the concept of Rule Based algorithms.

The characteristics of the proposed method are as follows:

First, Attention is given to piping systems from several different piping systems. similarity of modules and settings considered and costs and size of piping systems and similarities.

Second, the design process of the piping system will be divided into two stages: module definition and design development.

Third, to define effective modules that can be used in general on different ships, the design structure matrix is adopted.

"Ship optimization design is critical to the preliminary design of a ship. With the rapid development of computer technology, the simulation-based design (SBD) technique has been introduced into the field of ship design. Typical SBD consists of three parts: geometric reconstruction; CFD numerical simulation; and optimization. In the context of ship design, these are used to alter the shape of the ship, evaluate the objective function and to assess the hull form space respectively. As such, the SBD technique opens up new opportunities and paves the way for a new method for optimal ship design.This book discusses the problem of optimizing ship’s hulls, highlighting the key technologies of ship optimization design and presenting a series of hull-form optimization platforms. It includes several improved approaches and novel ideas with significant potential in this field"

Recently, the shipbuilding industry has been able to develop new production methods. This new method promotes design automation in order to produce ships more efficiently. The various production concepts, like block division, modularization and building ships with a standard design are possible solutions for improve production. Engine room design, including the piping system, is a complex process; therefore, modularization of its design is an effective strategy to minimize the complexity of the system. In addition, modularization plays an important role. This process requires a considerable number of man hours. This paper presents a new approach for engine room design based on the modularization concept. The characteristics of the proposed method are as follows: Attention was paid to all piping system of ship engine room. The cost and weight of the piping system were considered. to define an effective module, a design structure matrix was adopted. in the modularization using DSM, the Genetic Algorithm is used to obtain modules by considering some constraints like number of pipe connections and pipe cost. This study discusses the details of the above mentioned methods. In addition, simulation test of design optimization of a several piping systems were carried out to illustrate the design optimization procedure in detail and to verify the effectiveness of the proposed methodology.

"Modularization is one of the key strategies for increasing responsiveness to customers. In modular product architecture a wide variety of product configurations can be generated by altering a limited number of modules and components. Product modules are identified by grouping highly coupled components in the same module. A Design Structure Matrix (DSM) is a compact presentation of the interaction between the components. In this paper, Analytical Hierarchy Process (AHP) and Genetic Algorithm (GA)-based methodology is proposed for the clustering of highly coupled DSM components in modules. Multi-criteria DSMs are proposed, which are aggregated by using weights generated by AHP. A genetic algorithm is designed to change the order of components in DSM and to bring highly coupled interactions near the diagonal. An illustrative case study is also made to validate the proposed algorithm. Two large sized and two small size modules are identified by selecting high density clusters around the diagonal. The clustered DSM also shows independent components and loose coupling between the two modules."
