A variety of reference models such as CMMI, COBIT or ITIL support IT organizations to improve their processes. These process improvement reference models (IRMs) cover different domains such as IT development, IT Services or IT Governance but also share some similarities. As there are organizations that address multiple domains and need to coordinate their processes in their improvement we present MoSaIC, an approach to support organizations to efficiently adopt and conform to multiple IRMs. Our solution realizes a semantic integration of IRMs based on common meta-models. The resulting IRM integration model enables organizations to efficiently implement and asses multiple IRMs and to benefit from synergy effects.

The 1 to 1 relationships of charts of accounts, accounting journals and tables of accounting records with corresponding tables of accounts, business transactions and transactional records in the framework EPC II system have been presented in the paper. These tables are the main information kinds, that is tables in which one can write down all information needed for management and business process control in any enterprise, or they are composed of them. In this way it has been shown that the Theory of Enterprise Process Control is compatible with generally accepted accounting principles. This analysis is an example of demonstrating conformity of the EPC II theory with real management and process control systems. The main information kinds with their key attributes were taken from the complete list of them, which is included in the paper. What is more, the tight relationships between resource flow in business processes and turnover on the accounts of the framework EPC II system have been discussed. Owing to these relationships one can determine the impact of any decision variable on the accounting records in a given enterprise.

The paper is the third one of publications on the EPC theory. The acronym EPC has been replaced with EPC II to avoid confusing Enterprise Process Control with Event-driven Process Chain, which is a well known method of modeling process structures. Basic notions of the EPC II theory have been discussed in the paper using the example of a two-level business process, which is an educational model of production of housing parts of the final product in a household goods factory. For the higher level the follow-up production control system has been presented. For the lower level the central control of a business process has been discussed. For all examples tables of their relational models have been shown. The paper presents the EPC II notation for graphical modeling business processes and their control systems. It uses only 4 symbols from UML activity diagrams - structured activity, action, data store and object flow. It has been shown that business process models, expressed with notations of UML, BPMN, EPC, CPN may be always transformed to EPC II activity diagrams. What is more, with EPC II notation one can present not only structure of business processes in any organizational level of an enterprise, but also structure of their control systems.

In the paper the basic concepts of the theory of Enterprise Process Control (EPC II), as well as its most important results and directions of future work, have been discussed. It has been shown that in the synthetic picture of EPC II data structure every structural attribute of information elements may be assigned to one of the three general dimensions: knowledge on kinds of processes and resources, enterprise organization and labels of executions of definite business processes. Differences in concepts of business processes, resources and organizational units between the EPC II theory and the current standards have been pointed out. It has been demonstrated that the framework functional structure of integrated management systems is the same for every organizational level. The notions of business transactions have been introduced and then relationships between functional activities and business transactions have been described. Next, the relationships of bookkeeping accounts, entries and transactions with corresponding notions of the EPC II theory have been discussed. It has been shown how the EPC II theory may be applied to solving certain difficult problems of business process control, including the problem of building a universal framework system of management and process control and the problem of automatic adaptation of management systems software to structural changes of business processes.

The framework Enterprise Process Control system is a system with a relational database. Those of its tables which are not subclasses of other tables have been named "administrative information kinds". Their rows and their key attributes are called "information elements" and "structural attributes". The list of all structural attributes, as well as the list of all administrative information kinds together with their key attributes, have been presented in the paper. According to the thesis of universality of the framework EPC II system for each table of each real integrated management system there is a specialization relationship with one of information kinds belonging to this list or with a table of natural join of certain information kinds or with a projection of such a join on its selected columns. Therefore the number 25 of all structural attributes and the number 140 of all administrative information kinds seem to be relatively small. The list of information kinds has been discussed in parts corresponding to structural knowledge of enterprise resources and processes, to information places which are sets of information elements, to the structure of business process control systems, to batches and specimens of resources, to transitions, transactions and state of EPC II systems, to periodic plans and reports of enterprise activities and, finally, to orders of these activities.

W pracy przedstawiono podstawowe pojęcia teorii sterowania zasobami przedsiębiorstwa (teorii ERC). Teoria ERC jest opisem ogólnego modelu referencyjnego, który można wykorzystać do projektowania zintegrowanych systemów zarządzania i sterowania w przedsiębiorstwach. Meta-modelem systemów ERC są organizacyjne sieci informacji i tranzycji (OITN), o strukturze takiej, jak CPN. Struktura informacji w miejscach OITN jest jak w relacyjnych bazach danych.

Basic concepts of the Enterprise Resource Control theory (ERC) have been presented in the paper. The ERC theory is a description of a general reference model, which may be applied to design integrated planning and control systems for enterprises. The Organizational Information-Transition Nets (OITN) are a metamodel for ERC systems. The OITN structure imitates the CPN structure. The information structure in OITN places is like data structure in relational databases.

W ostatnich latach uważa się, że zdecentralizowane struktury produkcyjne to cel, jaki musi osiągnąć przedsiębiorstwo, aby zoptymalizować produkcję. W referacie przedstawiono podejście do oceny poziomu decentralizacji w pewnych sytuacjach produkcyjnych. Podejście to oparte jest na zestawie modeli służących do opisu i klasyfikacji aktualnej sytuacji produkcyjnej przedsiębiorstwa. Rozróżnia się modele odniesienia w pełni i częściowo scentralizowane lub zdecentralizowane oraz zadania produkcyjne podstawowe i wspomagające. Model składa się z profilów odpowiedniości pomocnych w klasyfikacji produkcji przedsiębiorstwa i pozwalających ustalić zmiany stopnia decentralizacji w różnych obszarach produkcji. Zidentyfikowane zmiany można skojarzyć ze odpowiednimi środkami realizacji za pomocą list kontrolnych. Środki te ocenia się poprzez ustalenie kosztów i czasu realizacji zmian.

In recent years decentralised production structures have been described as the final target a company has to reach for optimising the production performance. This paper will describe an approach which addresses the estimatlon of an appropriate level of decentralisation in certain production situations. The approach is based on a set of reference models for describing and classifying the current situation of a company's production. Looking at the reference models it is differentiated between fully and partly centralised and decentralised model types on the one hand, and between different basic and supporting production tasks on the other hand. The models consist of suitability profiles which help to classify a company's production and which allow to determine changes of the degree of decentralisation in the different production areas. The identified changes can be linked with improvement measures by the help of checklists. An evaluation of the measures is done by determining costs and time for realising these measures.
