Formulation of control policies for integrated research and development-production-inventory systems

Abstract

Multivariable system theory is used to synthesize continuous-time control policies for research and development-production-inventory systems. The block diagonalization method is used to study the asymptotic structure of the transfer function matrices of such systems. It is shown that the results obtained greatly facilitate the synthesis of high-grain error-actuated control policies which ensure that the closed-loop behavior of such systems becomes increasingly 'tight' and noninteracting as the value of the gain parameter is increased. The behavior of the controlled research and development-production-inventory system is illustrated by the presentation of the results of computer simulation studies showing typical transient and steady-state response characteristics.
