This paper employs mathematical modeling and algebraic approach to derive the optimal manufacturing batch size and number of shipment for a vendor-buyer integrated economic production quantity (EPQ) model with scrap. Unlike the conventional method by using differential calculus to determine replenishment lot size and optimal number of shipments for such an integrated system, this paper proposes...

This paper examines a manufacturer’s integrated planning problem for the production and the delivery of a set of orders. The manufacturer in this setting can use two vehicle types for outbound shipments. The first type of vehicle is available in unlimited numbers, but expensive. The second type, which is relatively low in its price, has limited and time-varying availability. We analyze the manu...

When a customer orders online, an e-tailer assigns the order to one or more of its warehouses and/or drop-shippers, so as to minimize procurement and transportation costs, based on the available current information. However, this assignment is necessarily myopic as it cannot account for any subsequent customer orders or future inventory replenishments. We examine the benefits from periodically ...

Assessment of export opportunities for softwood products from the North has been hampered by a lack of information describing foreign sales from the region. This article describes the value and volume of softwood products exported from the northern United States for 1980 through 1985. Roundwood productsmostly spruce logs from Maine and Vermont -are the largest northern softwood export. Canada, ...

Monthly data in physical units for seven industries are used to examine the production-smwthing hypothesis. The results strongly support this hypothesis. Significant effects of expected future sales on current production are found for four industries. and the estimated decision equations for all seven industries imply production-smoothing behavior. The previous negative results appear to be due...
