Partial maintainability and control in nonhomogeneous Markov manpower systems

Concepts of recruitment control in nonhomogeneous Markov manpower systems are studied, in order to determine subsets of structures in a graded population, which can be maintained in one step, using partial recruitment information necessary for each subset. Two necessary and sufficient conditions are derived, and the Simplex algorithm is used to describe the regions of the so-called partially maintainable structures. The results are illustrated by numerical examples and the consideration of some interesting special cases.
