The strategic design of a robust supply chain has as goal the configuration of the supply chain structure so that the performance of the supply chain remains of a consistently high quality for all possible future scenarios. We model this goal with an objective function that trades off the central tendency of the supply chain profit with the dispersion of the profit as measured by the standard d...

emphasis on milk yield (my) as well as milk yield persistency (myp) and calving interval (ci) is necessary to achieve more sustainable productionin dairy cattle. therefore the main objective of this study was to find an optimum regression model to estimate economic values for my, myp and ci.using a deterministic bio-economic model, seventyfiveproduction states differing mainly in my, mypand ciw...

in classic inventory control system, we assume that purchasing cost should be paid at time of delivery. but sometimes in order to encourage retailer to increase his order, postpond payment is provided by supplier as an incentive policy for retailer. in this paper a periodic inventory control model is invetigated in which the period between two consecutive replenishmnet is a random variable. in ...

this paper addresses a new product positioning problem, in which prices of the products are simultaneously determined in order to maximize both customer satisfaction and seller’s net profit. in this regard, customer willingness is identified with respect to the products within a family, upon which prices of the products are optimized so as to attain two objective functions: 1) maximizing custom...

This paper presents a midterm tactical planning model for the supply chain of a typical large company operating in the High Valley of the Black and Neuquén Rivers area of Argentina. A Mixed Integer Lineal Programming model has been developed, which maximizes the net profit of the company along a one-year time horizon divided in twelve monthly periods. Based on customer orders from three major m...
