The substance of the method consists in modeling parallel development of several model variants so that they tend - within an evolutional environment - to the optimum. Each of the variants has its own simulated time and during that time it develops, communicates with the other variants and – being stimulated by them - it modifies its own parameters. The variants that develop in a parallel manner but in different time flows can be realistically interpreted in a "quasi-parallel" manner within a mono processor system ; that enables to reproduce the computing ; certain obstacles related to the quasi-parallelism can be surmounted. The programming technology, system metaphor and application are described. In the project management field the method renders it possible to estimate the real value of a project as an alternative of compound real option approach.

At one part, the enterprise is interested to employ the minimum workers for that task, while at the other part the customers should be served as soon as possible after they send a message to the enterprise. Simulation of the variants viewed as materially possible, and then choosing the optimal one of them, is a good technique. A system that uses simulation is an anticipatory one and that anticipating the possible variants is also an anticipatory one, thus we meet nesting anticipatory systems. The anticipation of possible variants can be efficiently supported by applying object-oriented programming. That anticipation may pass over the design of one enterprise. The paper describes this technique and some illustrative examples.

The intelligence should cover different aspects, namely reactions to some natural language directives and anticipatory self-organizing. At the start phase, programming tools that will be able to cover the simulation models of the design variants are made and tested. They are structured into four main levels, namely (1) that of the world with communication in fuzzy terms, (2) that concerning the world of repeated existence of systems (used for managing a simulation study), (3) that oriented to simulation of information systems ( used for managing individual simulation experiments), and (4) that directed to the anticipatory abilities of the simulated systems. The programming tools are implemented in SIMULA.

Nevertheless, when the first tool allowing application of the OOP paradigm was presented to the world professional community in 1967, it offered much more than the mentioned paradigm. The whole system of the offered tools was later called Super-Object-Oriented programming tools (SOOP). Its origin and its abilities have several intimate relations to computer simulation and to computing anticipatory systems. The properties of the OOP and of SOOP and their differing are presented in the paper and the relation to the computing anticipatory systems as well.

The systematic algorithmization leads the authors to recognizing some formal properties that could be viewed in a rather natural way for the anticipatory systems in the weak sense and that could be automatically converted into simulation models implemented on computer. The formal properties, i.e. certain concepts of system analysis and their professional names are presented in this paper.

The technique named nested simulation consists in the simulation of elements that simulate their own environment using their own models. It enables a design process based on on-line predictive simulation to be analysed. Different implementations using SIMULA language have been performed. The features of the tool are presented. The interest for reconfigurable manufacturing systems is discussed.

A modern way to manage is to use (simulation) models of the sector. The exact rules holding for such systems (called patients-in-bed systems - shortly PBS) are presented in a form of axioms and for the purpose of computer models in a form of classes common for the object-oriented paradigm(OOP). The classes were applied to implement simulation models Ma oriented to the design and Mb oriented to the operation of PBS. A synthesis of both the models was made so that Mb was nested in Ma. The reason for the synthesis and the ways to overcome the difficulties are described in the paper. The two ways for to overcome the difficulties discover two ways for viewing to the anticipatory abilities of PBS.

When such a system is being designed both the modes interact. If simulation support is applied, the interaction causes that a system with simulating elements is simulated, i.e. one meets nesting simulation models. In other words, when we anticipate the system existence we should take into account the fact that anticipation will exist in the system during its operation stage. Although the essential problems related to the nesting of simulation models have been solved, some obstacles remain. They are rather of a psychological character and they can exist during the design of any system. For the branch of production systems, they are diminished by a simulation system REFLECTIVE QNOP, the principles of which are described in the present paper.

The concepts are namely matter/form and their influence to the law of extensionality, general/individual and time/eternity.
