2005 Graduate Catalog and 2004 Annual R & D Report Sirindhorn International Institute of Technology (SIIT) School of Manufacturing Systems and Mechanical Engineering Faculty Members and Research Interests, 2005 Dr. Bundit Limmeechokchai Associate Professor B.Eng. (1 st Class Honors) in Mechanical Engineering, King Mongkut's Institute of Technology North Bangkok M.Eng. in Rational Use of Energy, Asian Institute of Technology (AIT), Thailand D.Eng. in Energy Economics and Planning, Asian Institute of Technology (AIT), Thailand Areas of Specialization: Energy conservation and energy management in buildings, Demand-side management, Integrated resource planning, Modeling of energy and environment systems. Research Interests: Energy Management and Energy Conservation Energy management is the effective use of energy to maximize profits (minimize costs). A comprehensive energy management program is not purely technical. It takes into account planning and communication as well as marketing. Energy management includes energy productivity and energy awareness. In Thailand, energy management in buildings and industries is necessary to the country, as an energy importing country. The state has implemented energyconservation policies and measures for close to 20 years with little evidence of success. On the other hand, the energy consumption and GDP per capita in constant 1980 US$ from 1973 to 1990 are highly correlated with an elasticity of 1.12, which shows energy-consumption growth. The Energy-Conservation Promotion (ECP) Act was passed in 1992 and has been implemented since 1996 with one objective being the promotion of energy efficiency in buildings and industries. Cool-Storage Air-Conditioning Systems A cool-storage air-conditioning system (CSA) has been planned as a load shifting device in the Thai power sector since 1990. Its use can accrue benefits not only to the buildings' owners in terms of electricity bill savings but also to the electricity generating utility in terms of improving system reliability, decreasing marginal production costs at the peak periods, and deferring the installation of new power generating units. Integrated Resource Planning Traditionally, the method used in the power expansion process is to identify the sequence of generation additions which results in supplying the forecast load at the minimum overall costs, which has concentrated almost exclusively on supply-side options. However, it can be assumed that the saving of electricity through a demand side management (DSM) program is equivalent to building a new power generating unit. This concept is known as integrated resource planning (IRP). Therefore, each of the programs in DSM program of the Thai power sector will be evaluated in the IRP process. Dr. Chakguy Prakasvudhisarn Assistant Professor B.Eng. in Computer Engineering, Chulalongkorn University, Bangkok, Thailand M.S. in Computer Science, University of Oklahoma, OK, USA Ph.D. in Industrial Engineering, University of Oklahoma, OK, USA Areas of Specialization: Form Tolerance Evaluation, Automated Inspection (Vision and CMM systems), Computer Aided Manufacturing, Mathematical Programming, and Computational Intelligence (Support Vector Machines, Neural Networks, and Fuzzy Logic). Research Interests: Form Tolerance Evaluation Perfectly manufactured parts are nearly impossible to achieve due to variations in machining such as operators’ skills, tool characteristics, machine characteristics, and cost. Therefore, size and geometric tolerances of finished parts must be inspected. Form tolerances, a type of geometric tolerances, are applicable to single (individual) features or elements of single features. A form tolerance specifies a minimum zone within which the considered feature must be contained. Some common types are straightness, flatness, circularity or roundness, and cylindricity. However, complex forms, such as conicity and torusity have been largely ignored in the coordinate form literature. The deviation models of such forms are of interest. Their minimum zone solutions are then determined. 30
2005 Graduate Catalog and 2004 Annual R & D Report Sirindhorn International Institute of Technology (SIIT) Computational Intelligence Approaches for Automated Inspection For complex forms, the deviation models are highly nonlinear and they may not be differentiable. This may result in impracticality of gradient-based nonlinear optimization approaches. Computational Intelligence approaches are taken into consideration as alternatives to find minimum zone verification. The form tolerances algorithms are developed by utilizing the advantages of these approaches. In addition, they can be incorporated with CMM controller software for automated parts inspection.

Research Interests: Allocation of Heterogenous Workplace AS the product life cycle becomes shorter, the production shop floor must be able to effectively operate and switch among different types of products. Therefore, many organizations are moving toward greater flexibility in all stages of production in order to provide customers with greater product variety in less time. Creating a flexible workforce is one response to form a flexible organization to meet these market challenges. However, workers tend to be heterogeneous according to their productivity levels. Worker heterogeneity can significantly affact group performance particularly when workers perform sequential tasks. The research focuses on how to select, assign, and schedule workers in order to optimize system efficiency. Quality Improvements It is widely recognized that quality is fundamental to achieving long-term success. A renewed focus on customers and processes sets the stage for continuous improvement for industry, government, educational institutions, healthcare, and businesses. All have benefited from higher quality and productivity as well as reduced time and cost to develop, produce, and deliver products and services. Data-based total quality methods are the catalyst to help people achieve these benefits. The research focuses on designing industrial experiments. This field covers statistically based quality improvement methods useful in industrial settings; observational methods and design of experiments; experimentation to discover influential factors and to analyze sources of variation; and robust products. 31
