Opis:
In recent time, as the Chinese consumption level increases, the consumption quantity of high-value fruits, vegetables and seafood products have been increasing year by year. As a consequence, the traffic volume of refrigerated products also increases yearly and the popularization degree of the cold-chain transportation enhances. A low-temperature environment should be guaranteed during transportation, thus there is about 40% of diesel oil should be consumed by the refrigerating system and the cold-chain transportation becomes very costly. This study aimed to explore methods that could reduce the cost of transport packages of refrigerated products. On the basis of the heat transfer theory and the fluid mechanics theory, the heat exchanging process of corrugated cases during the operation of refrigerating system was analyzed, the heat transfer process of corrugated cases and refrigerator van was theoretically analyzed and the heat balance equation of corrugated cases was constructed.

Opis:
The paper refers to planning deliveries of food products (especially those available in certain seasons) to the recipients: supermarket networks. The paper presents two approaches to solving problems of simultaneous selection of suppliers and transportation modes and construction of product flow schedules with these transportation modes. Linear mathematical models have been built for the presented solution approaches. The cost criterion has been taken into consideration in them. The following costs have been taken into account: purchase of products by individual recipients, transport services, storing of products supplied before the planned deadlines and penalties for delays in supply of products. Two solution approaches (used for transportation planning and selection of suppliers and selection of transportation modes) have been compared. The monolithic approach calls for simultaneous solutions for the problems of supplier selection and selection of transportation modes. In the alternative (hierarchical) solution approach, suppliers are selected first, and then transportation companies and their relevant transportation modes are selected. The results of computational experiments are used for comparison of the hierarchical and monolithic solution approaches.

Opis:
The implementation of milk-run in Indonesia has been started since 2005. As a developing country, there is a challenge to operate milk-run smoothly especially in urban area due to severe traffic congestion and unfavourable road condition in some areas. This research aimed to analyze the practice of milk-run operation in one of the biggest Japanese automotive companies in Indonesia. Transportation Value Stream Mapping (TVSM) is applied in order to perform just-in-time delivery in the supply chain before operating milk-run. It is discussed that this company still need to continue in improving milk-run operation. The operation system needs control and integration from manufacturer, supplier and logistics partner. The advantage of milk-run operation is cost reduction and also support green logistics in decreasing emission of carbondioxide (CO2) by reducing the number of trucks used.

Opis:
Public and private stakeholders that operate land border crossings are increasingly concerned about long wait times for trucks crossing from Mexico into the United States. Long wait times are detrimental to the regional competiveness, supply chain operations, the environment in the region adjacent to the border crossings, and to the overall economic development. In order to have reliable and systematic information on border crossing time and delay, a system to measure travel time through the border is required. This paper describes the basic border crossing operations at the Texas/Mexico border that serves as the foundation to identify a technology that could be used to collect border crossing information. The design and deployment processes that were used for the implementation of the border crossing time measurement system for U.S.-bound commercial vehicles are described. The paper also presents the results of the system that was developed to disseminate border crossing and wait time data. Benefits to supply chain operators at land border crossings and next steps in the development of more border-related performance measures are described.

Opis:
The article presents an application of queuing theory (mass service) to describe transportation process. It presents the essential concepts of the queuing theory. The process of moving a load unit through the logistics centre was presented. To illustrate the issues an example of five-level, two-input queuing networks was examined.
W artykule przedstawiono zastosowanie teorii kolejek (masowej obsługi) do opisu procesu transportowego. W artykule zaprezentowano najistotniejsze pojęcia dotyczące teorii kolejek. Przedstawiono proces przemieszczania jednostki ładunkowej w centrum logistycznym. Dla zilustrowania zagadnienia przeanalizowano przykład dwuwejściowej, pięciostopniowej sieci kolejkowej.
