Competitiveness is defined to include both comparative and competitive advantage. Three different methodologies are applied in the analysis of the flower industries of South Africa and Australia: "Determinants of competitive advantage" methodology of Michael Porter (1990) describes the factors...

For years economists have ignored the diversity in agriculture and its potential to increase long run growth rates by enhancing a country's knowledge base. Non-traditional agriculture requires significant investments in the infrastructure and knowledge; and therefore, has the potential to...

Based on the analysis of fieldwork data collected by us from 102 households in the villages of Yaojia, Jizhuang and Wuzi, we analyze the phenomenon of differentiation behaviors of households who own different kinds of resources under the background of agricultural industrialization. The focus of...

On the basis the elementary theory of supply chain management, the features and problems in the supply-chain management of flowers in Yunnan Province are analyzed. The problems include poor image of flowers caused by low-end package, imperfect supply-chain structure, and weak processing section...

This paper analyzes how firms adjust to differences in market size and demand uncertainty by changing the frequency and size of their export shipments. In our inventory model, transportation costs and optimal shipment frequency are determined on the basis of demand as well as inventory and per...

Firms adjust to differences in market size and demand uncertainty by changing the frequency and size of their export shipments. In our inventory model, transportation costs and optimal shipment frequency are determined on the basis of demand as well as inventory and per shipments costs. Using a...

We consider the extended economic production quantity (EPQ) problem when demand follows a Poisson process in a production system. A fixed lot sizing policy is implemented to minimize fluctuation of workload, and to smooth production planning and inventory control. The considered costs include...

Most periodic review models in the inventory literature have assumed a fixed length of the review periods. In this note, we extend the work of Chiang (2008) , and consider backlogged and lost-sales periodic review models where the review periods are of a variable length and there is a fixed cost...

Das (Oper Res 25(5):835–850, <CitationRef CitationID="CR4">1977</CitationRef>) considered the optimization of a cost function associated with an (S − 1, S) inventory model assuming the parameters to be the initial number of items in the stock and the service rate. A similar optimization problem associated with an M/E <Subscript> k </Subscript>/1 queueing...</subscript></citationref>
