    A Study on ERP System Accertance Based on Technology Acceptance Model
    (University of the Thai Chamber of Commerce, 2007)

    User reluctance or unwillingness to adopt or use the newly implemented ERP system is often cited as one of the main reasons for ERP failures. To examine important antecedents leading to the lack of user acceptance towards the implemented ERP systems, this research reviewed the literature related to ERP adoption by users, developed hypotheses to explain ERP user acceptance, and conduct a survey to test the hypotheses. This research adapted the ERP acceptance model developed by Nan, et. al. (2004) and included five more constructs as the antecedents of ERP adoption. These new added variables are related to individual characteristics and the organizational contexts in which the ERP implementation takes place. Nine constructs comprises of ERP Ease of Use, ERP Usefulness, ERP Compatibility, ERP Business Fit, Shared Belief in The Benefit of ERP System, Facilitating Condition, ERP Self-Efficacy, Argument for Change and Personal Innovativeness of IT were hypothesized as antecedents to ERP systems symbolic adoption. This research uses 176 data set from several divisions of an Indonesian telecommunication company (Telco). Using structural equation modeling analysis, the result from the examined questionnaire shows that ERP Compatibility and Attitude Toward ERP System Use have direct effects on ERP Symbolic Adoption, while ERP Business Fit and ERP Usefulness influences ERP Symbolic Adoption by being fully mediated through Attitude.

    Capacity Reservation Policy for Priority Orders in Multiple Supply Plants
    (University of the Thai Chamber of Commerce, 2007)
    Chuang, Pao-Tiao
    This paper proposes an algorithm for selecting optimal capacity reservation policy for priority orders in multiple supply plants environment. The proposed approach, first, consolidates the available-to-promise (ATP) from each of the supply plants into cumulated ATP. Then, the capacity reservation policy is considered before the order dispatching is performed. The rate of tardiness for each order and the total revenue generated from order dispatching under various capacity policies are compared, respectively, based on which the optimal capacity reservation policy is selected. Results show that the more the capacity reservation, the higher rate of tardiness for the order with lower value but arriving earlier is. On the contrary, the rate of tardiness for the order with higher value but arriving later is lower. In addition, when the percentage of capacity reservation is increased, the total revenue generated from order dispatching is decreased gradually. This trend is continued until the percentage of capacity reservation is increased to a certain level (turning point). After the turning point, the total revenue is increased in an ascending trend. Thus, the optimal capacity reservation policy can be achieved by finding this turning point. Finally, a numerical example regarding an example with three supply plants to provide capacity for two distinct customer orders is simulated to show the proposed approach. Some managerial implications are provided.

    Firms operating within supply chains need to understandand consider whether their respective supply chains aresustainable or not. Sustainable supply chain relates tosupply chain issues that can range from child labour andexploitation of workers at suppliers’ premises on one handto ozone depletion, deforestation and global warming onthe other. These sustainability dimensions can beanalysed through 3 main perspectives which are accordingto mainstream sustainability framework: theenvironmental, social, and economic consideration. Inorder for a supply chain to be sustainable, there is a needto balance these three proposed dimension ofsustainability.The purpose of this paper is to develop a framework toassess the sustainability of any supply chain based on thethree sustainability dimensions of the environment, socialand economic requirements. It is expected that based onthese 3 sustainability dimensions, the characteristics forsustainable supply chain can be defined and proposed forfurther empirical research.

    Reducing Transportation Cost in Raw Milk Collection Using GIS Application
    (University of the Thai Chamber of Commerce, 2007)
    Ritvirool, Apichai
    ;
    A Milk Collection Center (MCC) is a facility forcollecting raw milk supplied by a dairy farmer based onthe demand of a milk manufacturer. Raw milk of eachMCC is supplied from the dairy farm where is locatedwithin 20 kilometers length from the MCC. Raw milkcollection is one of logistics activities. A reduction in thecost of collecting raw milk is one of the goals ofeffectively managing raw milk supply chain. Somefarmers presently self-deliver raw milk to MCC. In thissituation, therefore, the transportation cost is increased assupply chain management view point.This research aims to reduce transportation cost ofcollecting raw milk paid by dairy farmer. GeographicInformation System (GIS) is used to input, store, retrieve,manipulate, analyze and output geographically referenceddata in order to support decision making. GIS database isconstructed to store input data such as road network, roadsection’s lengths, farm locations, raw milk quantity ofeach farm and other relevant data. Then, GIS software isused to determine the routing networks of raw milkcollection from dairy farms to MCC.The results showed that the total distance of all routes inthe network was reduced by 54.8 % and transportationcost was reduced by 37.9 %.

    Increasing Customer Satisfaction Through the Integration of Customer &Commercial Logistics Processes
    (University of the Thai Chamber of Commerce, 2007)

    Customers are more and more demanding regardingfirms’ services or products. In today’s highly competitivebusiness environment, they need to go beyond orderqualifiers such as price, delivery lead time and productquality, to develop order winners that are related tocustomer service. This can be achieved by developing andmonitoring the performance of the "Customer andCommercial Logistics (C2L)" processes. C2L includes allthe processes involved in managing customerrelationships and flow of orders. We focus on the OrderManagement activity, which probably constitutes themain component of C2L. The first part of this paper willdiscuss it and present the issue of its integration in theOrder Fulfilment Process (OFP). In order to enhance theaccuracy of order promising and the reliability of orderfulfilment, the advanced ATP (AATP) function hasincreasingly attracted the attention of the supply chainmanagement research community. The interactionbetween entities is crucial to the success of the OFP. Theaim of this paper is to present a methodology, based onexisting research, to manage bulk orders. This preliminaryresearch should lead to the development of a specificAATP based on a multi-criteria analysis.
