Optimal Control of a Dedicated and a Flexible Server
نویسنده
چکیده
In this paper we consider a production environment consisting of two machines and two products. Machine 1 is a dedicated server, which is capable of producing product 1 only. Machine 2 is a flexible server that can produce both product 1 and product 2. Both product 1 and product 2 are produced to stock. We characterize the form of the optimal policies that maximize the average profit per unit time for machine 1 and machine 2 by modeling the system as a Markov Decision Process. In a numerical study, we identify the situations when it may be beneficial to invest in a dedicated machine-flexible machine system instead of a fully dedicated or a flexible machine production system.

Optimal flexible capacity in newsboy problem under stochastic demand and lead-time
In this paper, we consider a newsvendor who is going to invest on dedicated or flexible capacity, our goal is to find the optimal investment policy to maximize total profit while the newsvendor faces uncertainty in lead time and demand simultaneously. As highlighted in literature, demand is stochastic, while lead time is constant. However, in reality lead time uncertainty decreases newsvendor's...

متن کاملOptimal Control of a Flexible Server
We consider the dynamic scheduling of a multiclass queueing system with two servers, one dedicated (server 1) and one flexible (server 2), with no arrivals. Server 1 is dedicated to processing type-1 jobs while server 2 is primarily responsible for processing type-2 jobs but can also aid server 1 with its work. We address when it is optimal for server 2 to aid server 1 with type-1 jobs rather t...
متن کاملCOMPARISON BETWEEN MINIMUM AND NEAR MINIMUM TIME OPTIMAL CONTROL OF A FLEXIBLE SLEWING SPACECRAFT
In this paper, a minimum and near-minimum time optimal control laws are developed and compared for a rigid space platform with flexible links during an orientating maneuver with large angle of rotation. The control commands are considered as typical bang-bang with multiple symmetrical switches, the time optimal control solution for the rigid-body mode is obtained as a bang-bang function and app...
متن کاملNear-Minimum Time Optimal Control of Flexible Spacecraft during Slewing Maneuver
The rapid growth of space utilization requires extensive construction, and maintenance of space structures and satellites in orbit. 
This will, in turn, substantiate application of robotic systems in space. In this paper, a near-minimum-time optimal control law is developed for a rigid space platform with flexible links during an orientating maneuver with large angle of rotation. The time op...
