Estimates of the costs and consequences of many types of public policy proposals play an important role in the development and adoption of particular policy programs. Estimates of the same, or similar, policies that employ different modeling approaches can yield widely divergent results. Such divergence often undermines effective policy-making. These problems are particularly prominent for heal...

We propose two packet merging policies; T-policy and N-policy, during data collections of small sized packets from a large number of sources in order to mitigate the effect of telemetry data traffic. The T-policy and N-policy are to merge small sized packets after a waiting time T and N packet arrivals, respectively. The effect of two packet merging policies on a given network is analyzed in te...

Consider a two-level inventory system consisting of one supplier and one retailer. The retailer faces a Poisson demand with a known rate and applies base stock (one-for-one ordering) policy. That is, his inventory position is set to a pre-determined level, so the demand pattern is transferred exactly to the supplier. The supplier has an inventory system and a service unit with exponentially dis...

We study the value of multi-stage advance demand information (MADI) in a production system in which customers place an order in advance of their actual need, and each order goes through multiple stages before it becomes due. Any order which is not immediately …lled at its due date will be backordered. The producer must decide whether to produce or not based on real-time information regarding cu...

Available online 28 August 2014 In today's era of globalization, periodically new products with better value and added features are introduced into themarket. The rapid technological breakthroughs are creating significant risks of obsolescence at the product level. It creates enormous challenges to coordinate between technologymanagement and inventory control policies. Due to the dynamic nature...

In this paper we study a periodic review single item single stage inventory system with stochastic demand. In each time period the system must order none or at least as much as a minimum order quantity Qmin. Since the optimal structure of an ordering policy with a minimum order quantity is complicated, we propose an easy-to-use policy, which we call (R,S,Qmin) policy. Assuming linear holding an...

One policy making issue that needs to be addressed more effectively through an intergovernmental and participatory approach is entrepreneurship policy. Entrepreneurship is an area where interdependencies are very high, and the establishment of collaborative relationships such as networks is vital. Therefore, a network approach in the entrepreneurial policy-making process, which leads to the inv...

In this paper we introduce the optimal solution for a simple and yet practical inventory policy with the important characteristic which eliminates the uncertainty in demand for suppliers. In this new policy which is different from the classical inventory policies, the time interval between any two consecutive orders is fixed and the quantity of each order is one. Assuming the fixed ordering cos...

On July 31, 2008, the Constitutional Court of Colombia (the Court) handed down a decision (T-760/2008) that ordered a dramatic restructuring of the country’s health system [1]. The judgment came as the culmination of a wave of litigation to enforce the right to health, with tens of thousands of health rights cases before the Colombian courts each year [2]. Since 1992, the Court has staunchly up...
