Actualmente, las micro y pequeñas empresas (MYPEs) del sector textil no están totalmente concientizados con la importancia de llevar a cabo la aplicación de ciertos conocimientos que buscan la mejora los procesos productivos, aumento de la eficiencia y productividad, mejora la calidad y reducción de los tiempos de entrega. Para ello, se ha llevado a cabo una revisión exhaustiva de la literatura con el objetivo de recopilar modelos y técnicas del Lean Manufacturing que ayuden a reducir los desperdicios y lograr la mejora continua. En la presente investigación, se ha diseñado un modelo de Optimización de Desperdicios que incluye 3 dimensiones y cuatro componentes del sistema de producción que se relacionan con los 7 desperdicios del Lean Manufacturing. El modelo desarrollado no necesita del uso de tecnología, personal altamente calificado y puede ser implementado con gran facilidad a escenarios reales de las MYPEs textiles. Por último, se realizó un estudio de caso de aplicación del modelo de optimización en una pequeña empresa textil. Algunos resultados positivos se han registrado en la reducción del 60% de los desperdicios, tales como los defectos en las medias de algodón, movimientos innecesarios, exceso de inventarios, generando un incremento de la productividad en un 35%. Currently, the micro and small companies (MYPEs) of the textile sector are not fully aware of the importance of carrying out the application of certain knowledge that seeks to improve production processes, increase efficiency and productivity, improve quality and reduce delivery times. For this, an exhaustive review of the literature has been carried out with the objective of compiling Lean Manufacturing models and techniques that help reduce waste and achieve continuous improvement. In the present investigation, a waste optimization model has been designed that includes 3 dimensions and four components of the production system that are related to the 7 wastes of Lean Manufacturing. The model developed does not need the use of technology, highly qualified personnel and can be implemented with great ease to real scenarios of textile MYPE. Finally, a case study was carried out on the application of the optimization model in a small textile company. Some positive results have been registered in the reduction of 60% of waste, such as defects in cotton socks, unnecessary movements, excess of inventories, generating an increase in productivity by 35%. / Tesis

In response to the competitive global economy, lean manufacturing has become more prevalent in the United States. Manufacturing has changed, but cost accounting has not. Lean manufacturing has the potential to change the U.S. manufacturing economy, resulting in positive economic social change, yet it requires lean accounting to increase successful implementations. This study addressed the problem of lack of adoption of lean-accounting techniques like value-stream costing in lean-manufacturing enterprises. The purpose of this nonexperimental explanatory study was to investigate factors that influence the adoption of lean accounting. Using the technology acceptance model (TAM), based on the theory of reasoned action and the theory of planned behavior, this study examined whether management accountants- perceptions of the ease of use (PEOU), or perceived usefulness (PU) of value-stream costing may influence their intention (BI) to implement value-stream costing. The 2,307 attendees of the Lean Accounting Summit from 2005-2013 were invited to participate in an online survey; 70 attendees agreed to participate. Descriptive statistics, Pearson correlation coefficient, and multiple regressions were calculated. Statistically significant positive relationships emerged between PEOU, PU, and the intention to implement value-stream costing. Also, PEOU and PU for the individual accounted for 51% of the variance of BI, and PEOU and PU for the organization accounted for 49% of the variance of BI. This study added to the understanding how management accountants- perceptions positively influence their intention to implement value-stream costing. The relationships found by this study will create positive social change when used to influence the adoption of value-stream costing in order to increase the successful implementation of lean manufacturing in the U.S.

In line with the company-wide CS09 project being carried out at Volvo CE Components, Cell 14 will have changes in terms of distribution of machines and parts routing to meet the lean manufacturing goals established.  These changes are of course dependant on future production volumes, as well as lot sizing and material handling considerations. In this context, an important emphasis is given to the awareness of the performance measures that support decision making in these production development projects.  By using simulation as a confirmation tool, it is possible to re-assess these measures by testing the impact of changes in complex situations, in line with the lean manufacturing principles. The aim of the project is to develop a discrete event simulation model following the methodology proposed by Banks et al (1999).  A model of Cell 14 will be built using the software Technomatix Plant Simulation ® which is used by the Company and the results from the simulation study will be analyzed.

The actual industrial development linked to the financial situation over the world lead automotive and other companies to expand their production level to stay competitive. Changing an organization to raise its production or profit is not a one day journey, but requires some steps. Tools exist to develop the production level of manufacturing industry since more or less the fifties, and the continuous improvement is measured by some available and famous indicators around lean manufacturing mainly. Pressing equipment especially like a metal stamping press expressed through the following case study can be improved by respecting some fundamentals. Lean manufacturing aspects as 5 S’s and TPM (Total Productive Maintenance) for example are tools that can be applied to improve the production rate of a stamping press. To even better improve the OEE (Overall Equipment Effectiveness) of the same machine, a tool like SMED (Single Minute Exchange of Dies) reveals to be really powerful when improving the global output rate of the machine. The case study developed inside this present report aims to investigate all the possibilities to improve the OEE of pressing equipment facing theoretical aspects and reality issues. The tools involved are part of the content, but the way to support a company for the organizational change required to the success is another part of the content. Technical solutions are taking part of the outcome, and a strong link to change management is included. Correlation between both technical and managerial aspects is the main line followed to get the final results. An experimental and actual OEE is calculated, and improved following a rating according to the possible improvements. Those results are analyzed to provide a weighted feedback related to the whole research.
