A HOLISTIC APPROACH TO MANUFACTURING SYSTEM DESIGN IN THE DEFENSE AEROSPACE INDUSTRY

Manufacturing has evolved to become a critical element of the competitive skill set of defense aerospace firms. Given the changes in the acquisition environment and culture; traditional “thrown over the wall” means of developing and manufacturing products are insufficient. Also, manufacturing systems are complex systems that need to be carefully designed in a holistic manner and there are shortcomings with available tools and methods to assist in the design of these systems. This paper outlines the generation and validation of a framework to guide this manufacturing system design process.

Summary of Research Conducted by the Manufacturing Systems Team 1994-2002

The Manufacturing Systems team was one of the research teams within the Lean Aerospace Initiative (LAI) whose goal was to document, analyze and communicate the design attributes and relationships that lead to significant performance improvements in manufacturing systems in the defense aerospace industry. This report will provide an integrated record of this research using the Production Operations Transition to Lean Roadmap as its organizing framework.

Modeling and Analysis of Two-Part Type Manufacturing Systems

This paper presents a model and analysis of a synchronous tandem flow line that produces different part types on unreliable machines. The machines operate according to a static priority rule, operating on the highest priority part whenever possible, and operating on lower priority parts only when unable to produce those with higher priorities. We develop a new decomposition method to analyze the behavior of the manufacturing system by decomposing the long production line into small analytically tractable components. As a first step in modeling a production line with more than one part type, we restrict ourselves to the case where there are two part types. Detailed modeling and derivations are presented with a small two-part-type production line that consists of two processing machines and two demand machines. Then, a generalized longer flow line is analyzed. Furthermore, estimates for performance measures, such as average buffer levels and production rates, are presented and compared to extensive discrete event simulation. The quantitative behavior of the two-part type processing line under different demand scenarios is also provided.

Análisis de los componentes de la cadena de suministro y global manufacturing y su relación con el desempeño organizacional en el sector manufacturero

El presente trabajo tiene como objetivo mostrar la relación que existe entre la cadena de suministro, global manufacturing y su relación con el desempeño organizacional en el sector manufacturero. El proyecto va a estar divido en tres grandes partes, en primer lugar estará el marco conceptual donde se especificarán los conceptos más significativos que abarcan la investigación, seguido del marco teórico donde se expondrán las teorías y estudios encontrados, analizados y estudiados con el fin de desembocar en la tercer parte que serán las conclusiones y recomendaciones que se darán a partir de los análisis y teorías que compactan el tema de la relación existente entre la cadena de suministro, global manufacturing y el desempeño organizacional.

A firm-level analysis of ICT adoption in an emerging economy: evidence from the colombian manufacturing industries

This study examines ICT adoption among 3,759 Colombian manufacturing firms, and attempts to identify the factors that are conducive to the adoption and usage of ICT at the firm level. Our major findings are (i) that the adoption of a given information and communication technology is better facilitated when a firm is relatively large, has large human capital, engages in more innovative activities, and when a firm’s organizational structure is better aligned with the given technology; (ii) that positive associations between the key determinants and ICT adoptions are more pronounced for small and medium-sized firms than for large ones, and (iii) that information spillovers within industries is also a determinant of ICT adoptions by the firms.

Estudi i implantació del sistema Lean Manufacturing a una empresa convencional del sector de l'automòbil, per incrementar la competitivitat

El projecte es planteja la implantació de la metodologia LEAN en una de les plantes de producció d’una empresa del sector de la indústria de l’automòbil per aconseguir millorar la seva competitivitat. El projecte engloba l’anàlisi de les cadenes de valor de quatre dels productes més significatius que es fabriquen actualment a la planta, mitjançant la metodologia Value Stream Map (VSM), així com el desenvolupament de noves propostes per la millora de cadascuna de les cadenes

Essays on innovation in manufacturing environments: strategy and production

La present tesi doctoral és un recull de cinc articles científics que analitzen l'ús d'innovacions dins l'àmbit manufacturer. Entenent el concepte innovació en un sentit ampli, no només tecnològic. La tesi està estructurada en dos grans apartats, estratègia i producció. En el primer dels apartats, s'inclouen tres treballs. El primer treball és un anàlisi de quines són les principals barreres percebudes per les empreses en la cooperació en R&D. Els altres dos treballs són estudis empírics del comportament estratègic de les empreses que pertanyen al sector tèxtil i confecció. Respecte al segon gran apartat, producció, es presenten dos treballs. El primer treball, presenta per primer cop a Espanya dades detallades sobre l'ús d'innovacions tecnològiques dins l'àmbit manufacturer així com analitza el seu impacte en els resultats de l'empresa. Finalment, l'últim dels treballs estudia la relació entre l'ús d'innovacions organitzatives i la implantació de diferents nivells de qualitat dins l'empresa.

Assessment of virtual design and manufacturing techniques for fibre reinforced composite materials

Virtual tools are commonly used nowadays to optimize product design and manufacturing process of fibre reinforced composite materials. The present work focuses on two areas of interest to forecast the part performance and the production process particularities. The first part proposes a multi-physical optimization tool to support the concept stage of a composite part. The strategy is based on the strategic handling of information and, through a single control parameter, is able to evaluate the effects of design variations throughout all these steps in parallel. The second part targets the resin infusion process and the impact of thermal effects. The numerical and experimental approach allowed the identificationof improvement opportunities regarding the implementation of algorithms in commercially available simulation software.
