- Reference model and methodology to configure/reconfigure integrated product, process and facility development processes(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2010-02-01) Aca Sánchez, Joaquín; tolmquevedo; Tecnológico de Monterrey, Campus MonterreyEmerging economies, social and political transitions, and new ways of doing business are changing the world dramatically, these trends suggest that competitive advantages in the new global economy will belong to enterprises capable of develop high customized products. Manufacturing Industry play a leading role in regional development of Mexican Industry, however, the absence of formal programs for New Product Development place Mexican Industry at a competitive disadvantage with respect to other countries. In order to compete, Mexican Companies require adapting structured process to improve their practices in New Product Development. This research thesis proposes the methodological use of a Reference Model that allows the companies to create a Particular Model to set-up successful Integrated Product, Process and Facility Development Processes, independent of the industrial sector of a company, but focusing on specific issues of the company like market opportunities, technological constraints and declared goals. The Reference Model is structured in three dimensions: Processes, Stages and Activities. Processes are a description of the potential cases to be developed: Product Development, Process Development and/or Facility Development. Stages are a set of activities performed to achieve a partial result in a specific Process; this reference model has four types of stages: Conceptualization, Basic Development, Advanced Development and Launching. Activities are specific tasks that must be executed in order to complete a Stage; there are three types of Activities: Analysis, Synthesis and Evaluation. Particular Model is defined as the structured combination of Processes, Stages and Activities, capable to develop the desired product or product family allowing exchange information from one Process to other depending on the information available and the goal of the project. In order the company configures its Process, three activities must be achieved: (1) Project Definition; (2) Activity Sequence Identification; and (2) Activity Mapping in the Company. To demonstrate the use of the Reference Model the derived Methodology was employed in a metalworking company to create its Particular Model and define a New Product Development Program to introduce automotive products. The principal results obtained on this research thesis were: (1) A Reference Model for Integrated Product Process and Facility Development was developed; (2) A Methodology was developed to configure processes for product development; and (3) A case study was developed to demonstrate how to use the Reference Model and Systematic approach can be used to develop New Products. Some conclusions obtained from this research thesis were: (1) Benefits from Reference Model uses are configuration of processes for specific product development in short periods of time and increase of the feasibility of product modification; (2) In order to exploit fully configurability of the proposed systematic approach, Case Development is required to generate an Activities Library that allows reuse knowledge in future Process Configuration; and (3) Processes Configuration requires a steep learning curve, but its systematic structure makes it feasible to be automated and in long term a reduction in configuration time is presented.
- Holonic Environment Integration Methodology For Metal Working SMEs Manufacturing Systems: MES Holon(Instituto Tecnológico y de Estudios Superiores de Monterrey, 01/05/2004) Gaxiola Baqueiro, Luis Enrique; Ramírez Cadena, Miguel de Jesús; tolmquevedo; Tecnológico de Monterrey, Campus MonterreyNowadays, industrial enterprises, at any size and sub sector, are facing challenges derived from the globalization phenomena. Some of these challenges are the rapid response times demanded by global markets, variety, high quality without additional costs and service. An obstacle for the competitiveness increase is the lack of real time knowledge concerning to what is happening in the manufacturing floor, what is its process' performance, and its feedback. Some technologies have arisen in recent years, pretending to ameliorate this lack of knowledge, known also as “information gap�. One of the most outstanding mentioned technologies is represented by the Manufacturing Execution Systems (MES). MES is a recent-years IT (Information Technology) solution that constitutes a middleware and a resources' integrator among high-level decision software tools, such as ERP systems, and operation-floor control software tools, such as SCADA Systems (Supervisory Control and Data Acquisition Systems), acting as an information bridge. Nowadays, the implementation of Manufacturing Execution Systems (MES) in a wide diversity of industries is a trend that is arising invigorated in enterprises that are characterized by high stability environments, high investment capabilities and an advanced and well hierarchized automation technology. Unfortunately, the benefits of the intended information gap amelioration through this kind of systems is nowadays not available for SMEs (Small and Medium Enterprises) especially in industry undeveloped countries, like Mexico, in which most of the time, the focus is on the enterprise's survivorship (reflecting this in low investments trends) and not in the enterprise's growth (which would be reflected in long vision term investments). This kind of enterprises is also characterized by highly unstable production environments and low automation technology. Holonic Theory is a concept that arised in the 1960's, and its principles were originally employed to model social and biological behavior. The 1990's were the beginning of the efforts to incorporate the benefits of the Holonic Theory in the field of Manufacturing. Holonic Theory is highly suitable to those organizations that are not immersed in highly deterministic nor rigid structures. The modeling and implementation of MES software comprised by functional holons, employing available commercial software, with the fulfillment of some of the most relevant information technology requirements for the small and middle industry in Manufacturing enterprises (specifically in the metalworking area) is the main purpose of this research Present work is intended to help on the amelioration of the formerly mentioned Information Technology in SMEs -with a high focus on the metalworking sector-, specifically in the Manufacturing Information Management area, that prevail nowadays. Thus, the focus of present research is aimed to solve a real problem.
