    Battery transport optimization by a Vehicle Manufacturer in Thailand
    (Assumption University Press, 2016) Suphanida Leekijwiridhpol ; Srobol Smutkupt ; Vilasinee Srisarkun ; Chuthin Thanasarnaksorn
    This study is about battery transportation by a Vehicle Manufacturer that was found to have inefficient space utilization in the truck container. This problem negatively affected the company's profit and opportunity. Therefore, the use of GRASP (Greedy Randomized Adaptive Search Procedure) is proposed to minimize the problem substantially. In this research, a Vehicle Manufacturer focuses on its battery exports, which are transported by commercial vehicles. Data was collected by interviewing personnel, observing actual operations, and analyzing historical data. The result showed that a container truck utilized only 68% of its space. This impacted two areas: a high number of transportation trips, and high transportation cost. The conceptual framework of the research is to find the causes of the battery transportation problem as well as to implement GRASP methodology as a solution. GRASP methodology is a heuristics approach to allocating the right space. This methodology is widely applied in vessel container businesses, and can be useful in related fields such as truck containers. The objective of this research is to build a significant tool to enhance space utilization for loading batteries. The result indicates that the proposed solution can be accomplished and solve space utilization. According to this research, the company should implement a tower rack to stack batteries on pallets, and change the truck size from six wheels to ten wheels. These changes will provide cost saving, customer satisfaction, and collaboration, which increases the focus firm's competitiveness in the industry.

    Improvement of in-store delivery by applying the DMAIC model
    (Assumption University Press, 2015) Kitiya Wongbaesuj ; Roach, Scott ; Vilasinee Srisarkun
    This study aims to identify and correct problems in the in-store delivery process at the ABC Home and Construction Appliances Company in Thailand. Too much time was involved, from the customer placing a sales order at the warehouse to collecting goods at the pick-up point. These problems caused often considerable waits for those customers who had chosen to collect their goods themselves. The DMAIC model has been used to identify existing problems and improve the current process of the in-store delivery process. The methodology includes observation, interviews, and shared problem-solving. With an action plan, including KPIs, the picking process and waiting time are significantly reduced. Recommendations are made to ensure that the process remains in the improved state and in continually reviewed.

    Managing hazardous waste of chemical inventory : a case study of textile manufacturer in Thailand
    (Assumption University Press, 2019) Singh, Ravi Raj ; Vilasinee Srisarkun
    This research is a case study of textile manufacturer in Thailand. Being a manufacturing industry, the company is facing a lot of hazardous waste generating in their chemical storage to preparation area. The objective of this research was to find the certain root cause of the waste in the process, which is not adding value. The research is also trying to find the solution and implement appropriate methodology to eliminate non-value added activities from the hazardous chemical inventory. Recommendation, necessary action plan and solution were provided to get rid of non-value added activities and prevent repeated problem. This research mainly applied the process mapping, 5S and 7 wastes to identify the root cause of the problem and eliminate them. The researcher also suggested a continuous improvement plan in order to achieve a sustainable operational improvement of the company. The research observed that the main cause of an increase in hazardous waste is PVC Drums placed in the main inventory area. These PVC Drums were used in 13 different kinds of chemical generating 61.90% of hazardous waste in the process.

    Using DMAIC to improve an in-store delivery service
    (Assumption University Press, 2016) Kittima Limsirivallop ; Roach, Scott S. ; Vilasinee Srisarkun
    The objectives of this research were to identify problems, find solutions and implement actions to improve the delayed in-store delivery service process that was causing delay to customers at the AAA Company. This research applied the DMAIC (Define-Measure-Analyze-Improve-Control) model to improve the in-store delivery service within the firm's staff pick area. The service delays affected customer satisfaction. DMAIC helped the researcher analyze the root causes. The researcher also suggested an improvement plan with recommendations in order to achieve sustainable procedures to improve the company's operations. The result of the improvement plan has shown significant improvement in the in-store delivery service serving time. The time required for picking had been cut; therefore, customers' waiting time was reduced. The company needs to continue the improved process and also develops its own processes to cope with future changes. This is to ensure a sustained improvement carried out with practical monitoring to prevent problems from occurring.
