    The Planning and Forecasting Problemsfor Banknote Management
    (University of the Thai Chamber of Commerce, 2007)
    Balun, Pairote
    Under the Bank of Thailand’s new banknote circulation scheme, banknotes are distributed from the Note Printing Works to 11 banknote management centers, each of which serves multiple cash centers of the commercial banks. Meanwhile, each of those cash centers serves multiple bank branches, which provide cash-related services to the individual customers. We focused on the planning and forecasting problems of the supply chain of Thai banknotes, especially those confronting the central bank.The planning and forecasting problems for banknote management have interesting elements, features and requirements. Some of those requirements are the responsiveness and efficiency of production and distribution planning and the exceptional service level that the central bank provides to the commercial banks. In practice, there are three planning and forecasting problems. They are the problems of demand forecasting, distribution planning and production planning. We proposed solutions to these problems. The solutions themselves can then be developed into a web-based software for banknote management.To solve the demand forecasting problem, we standardized the forecasting procedures that were used previously. The techniques that we considered include regression, moving average, and time-series analysis. For the distribution problem, we considered both inventory and transportation costs in order to determine the optimal frequencies and lot sizes for banknote distribution to the banknote management centers. These economic order quantity analyses and results from the forecasting problem then lead to a banknote distribution plan. Finally, we used data on lead times, production calendar, machine availability, process capacity and production line setting to develop a banknote production plan.

    Managing Operational Risks: A Conceptual Framework for Operational Risk Management
    (University of the Thai Chamber of Commerce, 2007) ;
    Managing operational risks has become an importance aspect for every organisation. In the past, many operation management studies have focused on the improvement of operational performance. A large number of research publications included topics such as reduction of process variability, increasing flexibility or implementing controls in operations. It seems that research interest is now turning to operational risk management as well. A literature review carried out in this field revealed that organisations make use of various frameworks and models to deal with risks in their operations. Although these frameworks differ in some aspects, there is strong evidence, however, that organisations seem to favour an Operational Risk Management (ORM) framework that is based on commonly used management systems including the Quality Management System (QMS), Environmental Management System (EMS), and Occupational Health and Safety Management System (OHSMS). Drawing on these critical findings, this paper introduces aconceptual framework for managing operational risk based on commonly used management systems. It concludes with a discussion and direction for future research.

    A Conceptual Thought for Global Supply Networks (GSN) Architecture: Case Studies in Food Industry
    (University of the Thai Chamber of Commerce, 2007) ; ;
    The paper aims to extend international manufacturing network perspective towards global supply network(GSN) perspective by giving a fundamental thinking ofhow global supply networks (GSN) are constructed andreconstructed under global business environment througha few cases within the food industry. These cases werebasically conducted through interviews with internationalfood manufacturers in Thailand. As a result, the keycomponents of GSN architecture in the food industry areconceptually developed from literature review and casestudies. The GSN architecture comprises of two parts:structural components and infrastructural components.Additionally, the global business environment impacts onGSN structure and reconfiguration in the food industryare also preliminarily concluded in this paper. Finally,directions for future research are then suggested.

    An ESPC Algorithm Based Approach to Solve Inventory Deployment Problem
    (University of the Thai Chamber of Commerce, 2007) ; ;
    Wong, T. C.
    Global competitiveness has enforced the hefty industries to become more customized. To compete in the market they are targeting the customers who want exotic products, and faster and reliable deliveries. Industries are exploring the option of satisfying a portion of their demand by converting strategically placed products, this helps in increasing the variability of product produced by them in short lead time. In this paper, authors have proposed a new hybrid evolutionary algorithm named Endosymbiotic-Psychoclonal (ESPC) algorithm to determine the amount and type of product to stock as a semi product in inventory. In the proposed work the ability of previously proposed Psychoclonal algorithm to exploit the search space has been increased by making antibodies and antigen more cooperative interacting species. The efficacy of the proposed algorithm has been tested on randomly generated datasets and the results obtained, are compared with other evolutionary algorithms such as Genetic Algorithm (GA) and Simulated Annealing (SA). The comparison of ESPC with GA and SA proves the superiority of the proposed algorithm both in terms of quality of the solution obtained, and convergence time required to reach the optimal /near optimal value of the solution.

    An Exploratory Study of Across-Culture Effects: Case Study of Japanese-owned and Western-owned Firms in Thailand
    (University of the Thai Chamber of Commerce, 2007) ; ;
    The current presentation- rooted in a survey carried out inthe Japanese and Western firms with foreign employeesrevealsand discusses some practices of quality system asemphasized across national cultures. It is based onquality practices in Japanese-owned and Western-ownedfirms with Thai affiliations, then compared with thepractices in “parent” countries. Some similarities arerevealed, e.g. the motivations of quality initiative, sometools and techniques employed. However, somedistinctive differences are noticed, particularly theproblems that are countered those firms. Nevertheless,this exploratory study only describes the difference inapproaches among the countries but do not provide theexplanation as to why those differences occur. Thoseissues are pinpointed as the further research to investigatedifferences.
