In this paper we present a Nash dynamic game model of interactions among oil inventory and tariff policies for oil importing countries. The inventory policies consist of the rates for building up and drawing down strategic oil reserves, while the tariff policies consist of setting tariffs as a...

We present a greedy heuristic for the n job/1 machine scheduling problem with precedence constraints. This method is useful whenever the manager's optimization criteria is the sum of weighted or unweighted completion times, the sum of weighted or unweighted flow times, (with or without release...

We study the optimal control of a queueing system with Poisson input and a server capable of serving an infinite number of customers per batch. It is known that the optimal type of control policy is a control limit policy: service should begin if and only if the number of waiting customers is at...
