Shipment consolidation has been advocated by researchers and politicians as a means to reduce cost and improve environmental performance of logistics activities. This paper investigates consolidated transport solutions with a common shipment frequency. When a service provider designs such a solution for its customers, she faces a trade-o : to have the most time-sensitive customers join the cons...

This paper deals with a realistic multi-period liner ship fleet planning problem by incorporating stochastic dependency of the random and period-dependent container shipment demand. This problem is formulated as a multi-period stochastic programming model with a sequence of interrelated two-stage stochastic programming (2SSP) problems characterized ship fleet planning in each single period. A s...

There is a growing attention towards the application of Radio Frequency Identification (RFId) technology in the Fashion & Apparel supply chain. This paper describes a Lateral Trans-shipment replenishment policy enabled by item-level RFId tagging. In fact, in order to adopt a Lateral Transshipment policy, a firm should have an accurate visibility of both the inventory level in its warehouses and...

Materials and methods: 25 Minnesota swine herds were selected for the study. None of the participating farms identified clinical Salmonella as a problem in their operations. Ileocecal lymph nodes of swine from the 25 farms were collected repeatedly at slaughter by bluntly dissecting lymph nodes from the caudal mesentery. These nodes were macerated and cultured for Salmonella. inapparent infecti...

Details about the movement of trucks on postal express lines are investigated to improve the performances of mail distribution. A mixed driving pattern of trucks is introduced to minimize the transportation cost of a postal express line network with a service level requirement. We formulate this problem as a mixed p meeting depots location with shipment scheduling problem and build a MINLP mode...

Almost all insect pest control programmes currently releasing sterile insects as part of the area-wide integrated application of the sterile insect technique (SIT) use radioisotope irradiators that are loaded either with cobalt-60 or caesium-137, which produce ionizing radiation consisting of gamma rays. Irradiators such as the Gammacell 220 have proven to be extremely reliable for the purpose ...
