                             Opera
is computer tool system which will provide operational planning and 
management of industrial processes on the basis of network models in 
machine-and electonic device building, construction, at designing and 
repair complex objects.

     That may be easier and more evident than representation of a 
complex jobss and resources by Petri net: a rectangular - job, 
a circle-resource, line - connection?
     For some seconds you estimate a status of complex process, you see 
it is a colourful picture on the screen of yours personal computer. You 
have become interested any fragment? Press a key - and before you it's 
detailed characteristic. And that will be tomorrow, in one month, in the 
best, in the worse case? The system will simulate a situation - and on 
the screen new picture - the forecast.
     Powerful mathematical methods have lain in a basis of original 
algorithms, but you do not notice formal constructions. You in the world of
Jobs, Executors, Resources. Before you a network, time diagram of 
performance of jobs, the diagram of loading of resources, the table. The 
system itself will calculate terms of start of jobs relatives to optimum
from the point of view of the criteria chosen you, will generate plans of
executors. But a master of the situation - you. You know what not
to represent any network. Correct! Feel you like the artist! Routine 
checks and calculations of you should not to worry.
     The friendly interface, ease of adaptation and expansion, 
presentation and compactness of forms of representation of the information,
generation and seal of target documents, storage scheduled and actual 
statuses of object, high speed of performance of commands, absence of 
essential restrictions on the sizes of data, use of practical experience of 
the personnel of management and last achievements in the field of the 
theory of Petri nets is not fantasy, and characteristics of real system

                             Opera

   The opera is intended for automation of processes of operational 
planning and dispatching management of manufacture on the basis of tool 
computer means.
     The basic scope of system - management industrial activity on 
machine-building (electronic device building) enterprise, in construction, 
at designing and repair of complex objects - where it is necessary
to provide effective performance of complexes of interconnected jobs on the 
limited resources. Complexes of jobss should be are submitted in the network 
form.
     The system provides:
  - automatic balancing plans of divisions of the enterprise with their 
capacities (resources);
  - conducting and display of the actual information about current status 
of manufacture;
  - modelling industrial situations;
  - automatic and manual updating plans with maintenance of balance of 
capacities and labour inputs;
  - display of the information evident and convenient for work in kind of 
the network diagram (Petri net) and the time diagram;
  - generation of target printed forms of documents.
     Friendly graphic interaction with the user, ease of adaptation and 
expansion, color, compactness graphic and tabulared forms of representation 
of the information, use of knowledge base - the saved up experience of the 
personnel of management - are those the basic characteristics of system Opera.
     Orientation of production management to a commodity market, the consumer, 
and as consequence use of criterion "in necessary time, in the necessary 
quantity and in the necessary place" respond the best to modern realizations.
   Necessary means:. IBM - compatible personal computer in structure: 
volume of operative memory not less than 640 Kb; the store on a hard disk 
in capacity not less than 20Mb; the store on a floppy disk; graphic adapter 
EGA or VGA; the device of a conclusion to a seal in width up to 200 symbols 
(in Mode CONDENSED).

Shall be glad to become your business partner.

Please, send this file to everyone, whom as you consider, it may be interest.
