**2. CALS technologies and OTES**

According to contemporary notions in broad sense ILS being the CALS basis represents the system of scientific, design-project, organization-technical, manufactural and informational-management technologies, means and fractional measures during LC of high-quality MP for obtaining maximal required available level of quality and minimal product technical exploitational costs.

Contemporary ILS standards [7–12] being CALS vanguard methodology not in the right measure answer necessary purposes. CALS standard, have as debatable achievements and the following essential shortcomings:


<sup>2</sup> Functional product quality means how technical MP answers the functional purpose, exploitation, maintenance and repair. Exploitational-technical quality of MP is defined as adjustment to control, support and restoration during MP lifetime.

presents geographically distributed OTES whose consolidated budget at fixed time period is divided between two basic structure types of VE. First structure is responsible for MP creation and production with given functional and

exploitational-technical qualities.<sup>2</sup> Second structure is responsible for professional quality and staff life quality (professional skills, medical services, etc.). In this case OTES criteria for complex optimal OTES control<sup>3</sup> are defined by the social-

technical-economic efficiency indicators. Such indicators depends on the resources costs at required quality of basic processes in both structures during life cycle (LC). Besides standard ILS problems solving by such OTES systems modern IT provides deep OTES integration in general structures of local and global markets of

New approaches for OTES control are based on the probabilistic methodology for analytical modeling of stochastic processes coming from stochastic nature of internal and external noises. Special attention is paid to stochastic noises generated

In the modern ILS models and strategies ERP (enterprise resource planning) and MRP2 (manufacturing resource planning) only statically deterministic mathematics is used for solving planning problems. Unlike the existing methodology the suggested stochastic methodology firstly takes into account stochastic optimal planning processes dynamics and secondly performs current operative control using modern methods of stochastic analysis, modeling and estimation (filtering, for casting, identification, etc.) and control methods and technologies [1–4]. It gives opportunity to raise the level and the quality of OTES control by means of informational-analytical tools (IAT). There tools are being global control VE net based on CALS principles and technologies. Stochastic imitational models and complex imitational models give the opportunity to estimate the accuracy of analytical models and solve problems of optimal data processing and control in high dimensional and fast OTES-CALS.

Stochastic CALS methodology was firstly developed in [5] for modeling and analysis. Let us consider the development the stochastic estimation and control problems. We hope that these approaches will be useful for probabilistic systems engineering [6].

So ILS standards do not provide the whole realization of advantages for modern and perspective IT including staff structure in the field of stochastic modeling and control of two interconnected spheres: techno-sphere (technics and technologies) and social ones. These systems form the new the system class: OTES-CALS systems. Such systems destined for the production and realization of various services including staff structure, engineering and other categorical works providing exploitation, after sales MP support and repair, staff, medical, economical and financial support of all processes. New developed approach is based on the new stochastic modeling and control IT (**Figure 1**). These technologies are based on generalized social-technical-economic efficiency indicators for LC processes in comparison with usual CALS standards.

Research and control object in OTES are processes total LC of homogeneous sets of MP and resources. Special attention is paid to staff as object of professional training, improvement and medical service.
