Effective manufacturing strategies and practices
Intense global competition, rapid technological changes, advances in manufacturing and information technology and discerning customers force manufacturers to adopt manufacturing practices and competitive priorities that enable them to deliver high quality products in a short period of time. Identifying manufacturers’ competitive priorities and manufacturing practices has long been considered a key element in manufacturing strategy research. However, relatively little effort has been devoted to the measurement of these constructs. Dr. Karim’s current research involves identifying effective manufacturing practices that have a significant influence on product quality and business success. He has developed a conceptual model, which relates manufacturing practices with manufacturing performances. His research interests are:
- Effective manufacturing strategies and practices
- Manufacturing data mining
- Product quality & reliability improvement
- New product development.
Lean manufacturing and manufacturing data mining
Solving product yield and quality problems in a manufacturing process is becoming increasingly more difficult. There are various types of failures and their causes have complex, multi-factor interrelationships. Manufacturing process is now very complex due to the large number of processes, diverse equipment set and nonlinear process flows. Manufacturing database comprises of hundreds of process control, process step and wafer probe data. This huge volume of data coupled with quicker time to market expectations is making finding and resolving quality problems quickly an overwhelming task. Dr. Karim is currently involved in developing a data-mining methodology using dynamic growing self-organizing map (GSOM) to detect the faulty products in a manufacturing process. As part of the methodology, a clustering quality measure was developed to evaluate the performance of the algorithm in separating good and faulty products.
Solar drying and air conditioning
Solar energy has great potential for low temperature applications, particularly for drying of agricultural products. In drying and space heating, solar energy is an ideal choice because the warm air can be used directly, eliminating any need for an extra heat exchanger in the thermal system. Most fruits and vegetables contain more than 80% water and are, therefore, highly perishable. Losses of fruits and vegetables in developing countries are estimated to be 30–40% of production. The need to reduce postharvest losses is of paramount importance for these countries. Prospect of solar drying applications in the ASEAN region and in Australia is enormous. A large volume of fruits is produced in these countries and solar energy in abundant.
The design of efficient and suitable air collectors is one of the most important factors controlling the economics of solar drying. The majority of the solar dryers are equipped with flat plate collectors, which are considered inefficient. Dr. Karim has developed an efficient v-corrugated solar collector for drying purposes. A drying model for tropical fruits was also developed. His current interest is to further improve collector efficiency and use alternative materials for collectors, storage of solar energy and improvement in drying performance and drying models.
In countries with hot climates, air-conditioning forms a large proportion of annual peak electrical demand, requiring expansion of power plants to meet the peak demand, which goes unused most of the time. Use of well designed cool storage can offset the peak demand to a large extent. Dr. Karim has designed, constructed and tested an air conditioning system with naturally stratified storage tank. A new type of diffuser was designed and used in this system. Factors that influence the performance of chilled water storage tanks were investigated. The results indicated that stratified storage tank consistently stratified well without any physical barrier. Thermal efficiency of stratified storage tanks was as high as 90 percent, which indicates that stratified tanks can effectively be used as a load management technique.
Dr Karim has received over AS$2 million in research funding since 1999.
