iran is located in an area with high earthquake risk. there are over 20 active faults with length of 500 km and also densely populated parts of the country have been rendered vulnerable to strong earthquakes. however, existence of eight faults of the main faults of iran along with at least 18 faults with length of more than 100 km in kerman province have turned the place into one of the riskies...

Today’s global economy relies heavily on transportation and warehousing to deliver goods. Outsourcing has made the distribution networks complex with several layers of national (import) distribution centers (NDCs) and regional distribution centers (RDCs) between suppliers and retailers. More distribution nodes in the supply chain also means more inventory stockpiles. We present an integrated fa...

This study introduces the opportunity cost of distribution network. The centralized and distributed supply chain distribution network of bi-level programming model were constructed by defining the distribution centers face different stock losses, which include one manufacturer, more distribution centers and multiple retailers. Combined with the traditional genetic algorithm, this study designed...

Three dimensional (3D) nanostructured substrates play an important role in a variety of biomedically-oriented nanodevices as well as in functional devices created with the use of DNA scaffolding. Spacial arrangements of binding centers influence the efficiency of these 3D substrates. We compute and analyze the distribution of distances (q) between binding centers in the case where the centers a...

This study aims to develop a multi-period distribution system design model that provides an integrated view of the various costs, service quality and budget concerns within the planning horizon, as well as computationally feasible methods for obtaining solutions in realistic situations. The key design decisions considered in each period are: the number and location of distribution centers in t...

This paper considers the problem of constructing order batches for distribution centers using a data mining technique. With the advent of supply chain management, distribution centers fulfill a strategic role of achieving the logistics objectives of shorter cycle times, lower inventories, lower costs and better customer service. Many companies consider both their cost effectiveness and market p...

The consolidation of Distribution Centers (DCs) is a new trend in global logistics management, with a reduction in inventory costs often being cited as one of the main bene®ts. This paper uses an analytical modeling approach to study the impact on facility investment and inventory costs when several DCs are consolidated into a central DC. In particular, our model suggests that consolidation lea...

DC power distribution has been proposed as an alternative to AC power distribution in data centers, but misinformation and conflicting claims have confused the discussion. A detailed analysis and model show that many of the benefits commonly stated for DC distribution are unfounded or exaggerated. This paper explains why high efficiency AC will likely emerge as the dominant choice for data cent...
