Integrated lot sizing and tool management in automated manufacturing systems
We propose a new algorithm to solve lot sizing, tool allocation and machining conditions optimization problems simultaneously to minimize total production cost in a CNC environment. Most of the existing lot sizing and tool ...
Evaluation of army corps food supply system using simulation
The Food Supply System is one of the main elements of the Army Logistics System. The ultimate objective in a food supply system is to provide the food at the right time and in the right amount at the right place. If this ...
Scheduling in a three-machine flexible robotic cell
In this study, a three-machine flexible robotic manufacturing cell in which the CNC machines are used is considered. These machines are highly flexible and are capable of performing several different operations. Each machine ...
Routing and scheduling decisions in the hierarchical hub location problem
Hubs are facilities that consolidate and disseminate flow in many-to-many distribution systems. The hub location problem considers decisions that include the locations of hubs in a network and also the allocations of the ...
A simulation based learning meachanism for scheduling systems with continuous control and update structure
A simulation based learning mechanism is proposed in this study. The system learns in the manufacturing environment by constructing a learning tree and selects a dispatching rule from the tree for each scheduling period. ...
Optimal control of single-stage hybrid systems with poisson arrivals and deterministic service times
We tackle an optimal control problem for a single-stage hybrid system with Poisson arrivals and deterministic service times. In our setting, not only that the optimization problem is non-convex and non-differentiable, but ...
Aircraft recovery model with flight time controllability

A design of experiments approach to military deployment planning problem
We develop a logistics and transportation simulation that can be used to provide insights into potential outcomes of proposed military deployment plans.More specifically, we model the large-scale real-world military ...
Semantic scene classification for image annotation and retrieval
We describe an annotation and retrieval framework that uses a semantic image representation by contextual modeling of images using occurrence probabilities of concepts and objects. First, images are segmented into regions ...
A hub covering model for cargo delivery systems
The hub location problem appears in a variety of applications including airline systems, cargo delivery systems, and telecommunication network design. When we analyze the application areas separately, we observe that each ...
