This paper addresses the transportation of valuable goods in which security carriers are interested to optimize operating costs and vehicle routes’ security. In real operations, route planning scheduling normally performed manually based on individual experience. Hereupon, an optimizing approach should be developed target robbery risk reduction distribution network’ operational costs. Facing da...

It is inconceivable how chaotic the world would look to humans, faced with innumerable decisions a day to be made under uncertainty, had they been lacking the capacity to distinguish the relevant from the irrelevant—a capacity which computationally amounts to handling probabilistic independence relations. The highly parallel and distributed computational machinery of the brain suggests that a s...

Background & Aims: Nanosilver-based paint is a new technology with antimicrobial and antifungal characteristics. These characteristics were investigated in this study with regard to fungal contamination in hospitals. Method: Regarding hospitalization of transplant patients and their sensitivity to hospital infections, two similar rooms were selected in nephrology ward. One of them was paint...

multistage stochastic programming is a key technology for making decisions over time in an uncertain environment. one of the promising areas in which this technology is implementable, is medium term planning of electricity production and trading where decision makers are typically faced with uncertain parameters (such as future demands and market prices) that can be described by stochastic proc...

In Time Warp simulations, the overheads associated with rollbacks, state-saving and the communication induced by rollbacks are the chief contributors to the cost of the simulation; thus, these aspects of the simulation have been primary targets for optimizations. Unfortunately, the behavior of the Time Warp simulation is highly dynamic and greatly influenced by the application being simulated. ...

This paper presents an object-oriented implementation of Lucid. We implement each variable in a Lucid program as a class. An object of the class is the variable in a context. An object evaluates itself when it receives a demand for its value and stores the value. Evaluation of a program involves object self-evaluations and message passing of demands among objects. Some optimization issues are a...
