In designing for ship production, the production method should be considered and it’s possible to reduce the manufacturing cost in designing procedure. A review of background of ship design that had minimized production costs, shows the principles and problems of these methods. Modern designing methods for manufacturing, considers hydrodynamic efficiency and less manufacturing cost. Quant...

In this research, computer simulation is used for Electronic Manufacturing Service (EMS) plant layout analysis. The current layout of this manufacturing plant is a process layout, which is not suitable due to the nature of an EMS that has high-volume and high-variety environment. Moreover, quick response and high flexibility are also needed. Then, cellular manufacturing layout design was determ...

We have developed a methodology to diagnose the physical mechanisms limiting the manufacturing uniformity of millimeter-wave power InAlAs/InGaAs HEMT’s on InP. A statistical analysis was carried out on dc figures of merit obtained from a large number of actual devices on an experimental wafer. correlation studies and principal component analysis of the results indicated that variations in Si de...

In this paper, a mixed-integer linearized programming (MINLP) model is presented to design a group layout (GL) of a cellular manufacturing system (CMS) in a dynamic environment with considering production planning (PP) decisions. This model incorporates with an extensive coverage of important manufacturing features used in the design of CMSs. There are also some features that make the presented...

Cellular Manufacturing System (CMS) is an application of Group Technology (GT) that allows decomposing a manufacturing system into subsystems. Grouping the machines and parts in a cellular manufacturing system, based on similarities is known as cell formation problem (CFP) which is an NP-hard problem. In this paper, a mathematical model is proposed for CFP and is solved using the Ant Colony Opt...

It is a trend to implement mass customization (MC) to meet customer demands and win the global competition. With mass customization, products can be produced with low cost, high quality, and in time as mass production. To implement MC, today’s manufacturing process should be reengineered. However, it is believed that manufacturing process reengineering (MPR) is a highly risk job. A manufacturin...

Machines are a key element in the production system and their failure causes irreparable effects in terms of cost and time. In this paper, a new multi-objective mathematical model for dynamic cellular manufacturing system (DCMS) is provided with consideration of machine reliability and alternative process routes. In this dynamic model, we attempt to resolve the problem of integrated family (par...

Cellular manufacturing (CM) has acquired an upward interest of researchers in recent era. The most important problem in designing cellular manufacturing systems is the cell formation (CF), which constructs part families with similar processing requirements and designates machines into machine cells to optimize the production process. This article presents a short research report based on hybrid...
