This paper studies the optimal conduct of monetary policy in a multisector economy which firms buy and sell intermediate goods over production network. We first provide necessary sufficient condition for policy's ability to implement flexible?price equilibria presence nominal rigidities show that, generically, no can first?best allocation. then characterize terms economy's network extent nature...

In flexible manufacturing environments, the performance of a production system is often affected by the sequence of operation. While performance evaluation, improvement and lean design of production system have been studied extensively, the joint effect of productivity and quality parameters on operation sequencing remains practically unexplored. Indeed, determining the optimal operation sequen...

This study aimed at presenting a method for formulating optimal production, repair and replacement policies. The system was based on the production rate of defective parts and machine repairs and then was set up to optimize maintenance activities and related costs. The machine is either repaired or replaced. The machine is changed completely in the replacement process, but the productio...

The trend towards higher performance mechanical systems has naturally led to the need to design such systems in an optimal fashion. Lighter components and higher operating speeds both demand a level of design a step above that provided conventionally. This paper describes a research effort aimed at developing the methodology for such system design. The methodology is based on accurate computer ...
