An important observation in supply chain management, known as the bullwhip effect, suggests that demand variability increases as one moves up a supply chain. In this paper we quantify this effect for simple, two-stage supply chains consisting of a single retailer and a single manufacturer. Our...

A new approach to the solution of the facilities layout problem on the plane is presented in this paper. A simple procedure that can replace the dispersion phase of DISCON is constructed. The result of the new method is a scatter diagram of the facilities on the plane that can be used by...

The objective of the one-center model (single facility minimax location in the plane) is changed to be the maximum weighted number of demand points within a given weighted distance from the facility. The paper presents an O(n² log n) algorithm for the model along with some computational experience.
