Integrated Logistics Support (ILS) is disciplined and unified management including activities in product life cycle management to create a product maintenance system (MS) to support the product throughout its intended life cycle at an acceptable cost. Along with information models combining product descriptions such as breakdowns, fault trees and methods of restorations, etc., mathematical models considered effective tools to get optimal results are proposed. The paper will present mathematical models, which play important roles in assessing and estimating material demand (spare parts), for the material supply management. These models are applied, in different levels of the ILS system, to the direct calculation of the material demands for scheduled and unscheduled maintenance
