POST-HARVEST LOSSES DURING THE TRANSPORTATION OF GRAINS FROM FARMS TO AGGREGATION POINTS
by José Vicente Caixeta-Filho, Thiago Péra
Abstract: All of Brazils competitive advantages and productive gains tend to bleed away as its farm products pass through the various post-harvest stages, mainly due to logistic bottlenecks and deficiencies. To improve the prognosis for food security, one can avoid losses along the supply chain. This research is intended to adapt indicators and mitigation strategies derived through research in the United States to reduce post-harvest losses, especially in the transport of grains, and make this information available in Brazil. The implementation of a specific policy designed to prevent post-harvest loss in the US by either a public or private agent was not encountered during this research, which makes one think that this type of care is mostly driven by the market, economics, and perhaps the farmers interest in protecting their harvested grains and taking pride in a job well done.

The Feasibility Study of Promotion Activities in Farmers' Markets with Regional Agricultural Products
by Tzong-Ru (Jiun-Shen) Lee, Hsing-Wen Wang, Yi-Hsiang Hsu, Ya-Ling Tsai, Ching-Kuei Kao
Abstract: The farmers market is one of the channels that enable farmers to distribute their products. If the healthy and nutritional regional agricultural products can be integrated into the market as well as select the best marketing strategy and promotions after market research and consumer analysis, consumers can be stimulated to buy the products, instead of always demanding for healthy food, as well as interact face to face with producers. rn This paper designed different questionnaires for administrators, farmers, and consumers of 27 farmers markets in Taiwan. With the aid of grey relational analysis, the important promotional campaigns are determined. rn Based on answers of questionnaires, the important way to combine regional agricultural products and farmers market and the important promotional campaigns are determined. The important promotional campaigns can help governments in establishing indexes to assess the performance of markets and can facilitate communication with the farmers market. rn Based on results, this paper forwarded four suggestions concerning market management and policy making in the future for both the market administrators and the agricultural affair authorities.rn

Strategic risk management in the stocking decisions of frozen vegetables
by Yenming Chen, Tzong-Ru (Jiun-Shen) Lee, Yaqian Xiao, Miaohua Lin, Yunxuan Li
Abstract: Many crops are harvested once a year and the produces will meet the requirements of the entire year. For example, carrots usually harvest in winter and most of them must be refrigerated to fulfill the annual demands. The remains are then released to the fresh auction market. The refrigerated vegetables will be carefully released to the market month by month according to the expected demand of the entire year. Because this amount of refrigerated is fixed, releasing too early will lose the future opportunities in unknown demand surge. However, keeping the hoarding will crash the supplier if the demand surges were not realized. The supplier makes money if he/she wins the bet and loses money otherwise. In this study, simulated optimization analysis is carried out based on a design of experiments. This analysis aims to explore the interdependence among influencing factors for seeking maximum profit and the best hoarding strategy. Results show that (1) the higher the probability of the natural disease in the future, the more the hoarding; (2) when substitutive vegetables are expected to be scarce, the hoarding should increase; (3) when the quality of this batch of harvest is worse, then the hoarding should decrease. Our simulation results show that the profit reach the highest if natural shipments are 40,000 t. Increase supplies beyond the natural shipment quantity does not necessarily increase profits.
Keywords: root vegetables; frozen hoarding; simulated optimization; annual harvest; uncertain demand; substitutive produces; supply demand balance.
Optimizing supply chain management using robust control synthesis
by Xiao Xu, Tran Xuan Thung, Hwan-Seong Kim, Sam-Sang You
Abstract: The inventory management of supply chain is concerned with an efficient transportation of materials and products through supply chain members. In this paper, a series of linear models have been presented with lag time uncertainty for improving inventory management. In addition, a fluid analogy has been used for a single-product mmanufacturing system, or the basic unit of a supply chain. Robust control synthesis, which has been proved to cope withits ability for the system with high uncertainty, is utilized in optimizing the inventory management and guaranteeing highperformance of complete system. In addition, this control scheme aims to ensure the customer satisfaction by tracking and keeping the actual inventory close to target inventory under the influence of uncertainty. The extensive numerical simulations have been carried out to validate the proposed approach against disturbances. Finally, the simulation results show that the robust control system ensuresgood ability on keeping the target inventory under uncertainty.
Keywords: inventory management; supply chain; disturbance and uncertainty; fluid analogy; robust control synthesis; customer satisfaction.
Logistics and Stock Market Inter-dependence: The Case of China
by Jinghan Cai, Xiaobing Li
Abstract: The inter-dependence between different stock markets around the world has been in the forefront of academic and public interests. In this paper, we study the channel of the stock market inter-dependence between Chinese stock market and other markets around the world. We analyze the daily returns of major stock indices to discover the path of the transmission of shocks from Chinese stock market. We find out that, the difference in logistics from countries plays an important role in explaining the transmission of stock market shocks.
Keywords: Inter-dependence; global stock returns; logistics.
