**3.4 Modeling and analysis of aircraft vehicles park life cycle**

Following [16] let us consider informational-analytical tools (IAT) for aircraft vehicle park modeling and control by technical-economic efficiency criteria after sales maintenance products (ASMP).

IAT modular includes:


#### *3.4.1 Normative DB (NDB)*

According to contract supplier creates NDB according to standards DEFSTAN 00-600, S1000D, S2000 M and specifications S1000D, S2000 M. For IAT acceleration there are designed emulated DB (DBE) in the form of additional tables. Information from NDB automatically comes into DBE. These data characterize:


• mean capacity of regulation works (RW);

• coefficient of technical readiness along the park for each CP (0…1);

This software tool is destined for automatic work with delivery list SP for forming SP optimal program for any fixed time period of exploitation (including annual application) providing given level of technical readiness of FMP park at

• delivery cost of SP along FMP park;

• cost of ASS for LC cost estimation.

conditions of minimal purchasing price. Structure of initial parameters includes:

• service prices (repair and delivery);

• regular amount of FMP;

• CP real mean lifetime;

**125**

*3.4.4 Optimization block for annual application*

Output forecasting characteristics are the following:

• coefficient of technical readiness for FMP park;

• calculating reliability or exploitation for each CP;

• annual budget for CP repair and SP delivery;

• amount of CP and FMP being in repair;

• planning annual lifetime FMP and CP;

• planning time period (from 1 year to lifetime);

• required level of technical readiness coefficient.

• level of price escalation for planning time period;

• CP surplus in store.
