A Conceptual Design of Infrastructures and Facilities in Distribution Center for Frozen and Chilled Fishery Products This study aims to propose a conceptual design of infrastructures and facilities in the distribution center for frozen and chilled fishery products connecting lower northern provinces to the nearby countries. Firstly, several data were collected and analyzed including primary data and secondary data. Secondly, the activities were listed based on primary data and secondary data. Thirdly, the infrastructures and facilities are proposed that were listed from the activity analysis. Finally, the conceptual design was proposed for designing the infrastructures and facilities in the distribution center for frozen and chilled fishery products. The general function of infrastructures and facilities in the distribution center was firstly proposed. Then, the additional functions that might be integrated were proposed in which the additional functions consisted of retail function, light industrial function, and custom function. This study presented not only possible activities but also infrastructures and facilities in the distribution center for frozen and chilled fishery products to connect lower northern provinces to the nearby countries in which this lead to the development of the economic growth in Thailand and neighboring countries as well.

Analyzing the Impact of Vehicle Speed on Distribution Cost for Cold Chain Logistics The cold chain logistics industry has a promising prospect, while high costs impede its development. In order to reduce cost pressure on cold chain logistics, this paper investigates the impact of vehicle speed on distribution cost for cold chain logistics. Firstly, a mathematical model with which to minimize the total cost is constructed. The subcosts consist of fixed costs, fuel costs, refrigeration costs and damage costs. Secondly, an actual case data is used to conduct the experiments. Through experiments, it is demonstrated that optimizing vehicle speed can greatly reduce the total cost of the cold chain logistics. We also find that there is a reasonable speed range where the total cost changes slightly. Furthermore, this paper also discussed the impacts of spoilage rate and unit refrigeration cost on optimal speed and the reasonable speed range. The results show that as spoilage rate and unit refrigeration cost increase, both the optimal speed and the reasonable speed range will firstly increase and then stabilize. Finally, some managerial implications based on our findings were also presented targeting enterprises and the government.
