Ordering Policies in an environment of Stochastic Yields and Substitutable Demands

Ordering Policies in an environment of Stochastic Yields and Substitutable Demands

In this paper we model production problems where yields are stochastic, demands are substitutable, and several items are jointly produced. We have formulated this problem as a profit maximizing convex program, and have studied two solution procedures. The first method solves finite horizon stochastic programs on a rolling horizon basis. We have developed a decomposition algorithm for solving th...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
