In this paper I analyze three artificial examples of empirical equivalence: van Fraassen‟s alternative formulations of Newton‟s theory, the Poincaré-Reichenbach argument for the conventionality of geometry; and predictively equivalent „systems of the world‟. These examples have received attention in the philosophy of science literature because they are supposed to illustrate the connection betw...

Economists were interested in economic stabilization policies as early as the 1930’s but the formal applications of stability theory from the classical control theory to economic analysis appeared in the early 1950’s when a number of control engineers actively collaborated with economists on economic stability and feedback mechanisms. The theory of optimal control resulting from the contributio...

This paper addresses control design in networked control system by considering stochastic packet dropouts in the forward path of the control loop. The packet dropouts are modelled by mutually independent stochastic variables satisfying Bernoulli binary distribution. A sliding mode controller is utilized to overcome the adverse influences of stochastic packet dropouts in networked control system...

in classic inventory control system, we assume that purchasing cost should be paid at time of delivery. but sometimes in order to encourage retailer to increase his order, postpond payment is provided by supplier as an incentive policy for retailer. in this paper a periodic inventory control model is invetigated in which the period between two consecutive replenishmnet is a random variable. in ...

In this paper we discuss the Stochastic Control Problem, which deals with the best way to control a stochastic system and has applications in fields as diverse as robotics, finance, and industry. After quickly reviewing mathematical probability and stochastic integration, we prove the HamiltonJacobi-Bellman equations for stochastic control, which transform the Stochastic Control Problem into a ...

We consider an existence theorem for controi systems whose state variables for every t are in C, the set of continuous functions varying over a given set L The dependence of the state variables upon a ~ / i s induced by their dependence upon the initial state and the state equation governing the system. In contrast, the control u ---u(t) is taken as a measurable function of t alone. The usual s...
