Motivated by a purpose of closing the gap between theory and practice, this paper demonstrates how a well-known formal method is used to design a suitable control strategy for a large system. The formal method must deal with issues of complexity which usually prevent analysis of the large plant. The proposed strategies are based on modular principles and decomposition techniques and are proven to be able to cope with the complexity of the analysis of the investigated plant.

Zasadniczym celem niniejszego artykułu jest przedstawienie zalet i wad stosowania modeli referencyjnych podczas wdrożenia standardowego systemu informatycznego w przedsiębiorstwie. Modele referencyjne opracowane na podstawie tzw. najlepszych praktyk biznesowych są obecnie powszechnie stosowane jako narzędzie modelowania i usprawniania procesów w organizacji. W pierwszej części artykułu przybliżono pojęcie projektu wdrożeniowego oraz zdefiniowano termin "modele referencyjne". Druga część przedstawia korzyści i problemy związane z wykorzystaniem modeli podczas dostosowywania standardowego oprogramowania wspomagającego zarządzanie do potrzeb przedsiębiorstwa.

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.(original abstract)

nr nr 3

EN

The essential part of the theory of Enterprise Process Control (the EPC theory) is a formal description of the framework EPC system. It is a universal reference model of integrated management and process control systems for all enterprises, regardless of their trade and size. Basic notions of the EPC theory have been presented in the paper. Certain definitions of broadly known terms (e.g. organizational system, process, resource, control unit, functional layer) are slightly different than the ones that are most often formulated. The purpose of these modifications is precise presentation of relationships between defined notions. Furthermore many new notions (functional subsystem, functional unit, transition unit, information place, reengineering layer, readiness variant, organizational resources and the like) have been introduced. They are necessary for presenting organizational and functional structure of the framework EPC system. The EPC theory has deductive nature and its notions are formulated on the basis of the more general, previously defined ones.(original abstract)

Tylko to, co jest mierzone, może być właściwie zarządzane. Proces pomiaru powinien służyć ciągłemu doskonaleniu przedsiębiorstw i całych łańcuchów dostaw. Dane z systemu pomiaru powinny powodować wzrost współpracy i pomagać w podejmowaniu decyzji o zmianach na poziomie operacyjnym, a z drugiej strony może to być ważna informacja przy przedefiniowaniu strategii. Pozwala to na rozwój łańcuchów dostaw opartych na wiedzy, gdzie zakres współpracy jest dosłownie nieograniczony (dotyczy to również aspektów ekologicznych). Istnieją dwa podstawowe podejścia do pomiaru wydajności łańcucha dostaw: kompleksowy pomiar, który patrzy na wyniki całego łańcucha (który można rozdzielić na poszczególne szczeble i poziomy), oraz pomiar częściowy, gdy mierzymy tylko niektóre aspekty. Często praktykowany jest tylko pomiar oddzielnie działających firm, a nie całego łańcucha. Problem jest jeszcze bardziej widoczny, jeśli chodzi o pomiar wydajności działań ekologicznych w zintegrowanych łańcuchach dostaw. W artykule opisano możliwości oceny wyników GSCM. Przedstawiono i oceniono główne wyzwania i przeszkody stojące przed pomiarem wyników zielonych łańcuchów dostaw.(abstrakt oryginalny)

Only what is measured can be managed properly. And the measurement process should serve a continuous improvement of companies and whole supply chains. Data from the performance measurement system should cause an increase of cooperation and help in taking right decisions about changes at the operational level, and on the other hand, are an important information when redefining strategies. This will allow for the development of the supply chain based on knowledge, in which the scope of cooperation is literally unlimited (including green aspects). There are two basic approaches to measuring the performance of supply chains: a comprehensive measurement that measures the results of the entire chain (which can be divided into individual tiers and levels) and partial measurement when we measure only certain aspects. Often, in practice, only measurement of separately operating companies is practiced by companies, not throughout chains. And the problem is even more evident when it comes to measuring performance of green activities in integrated supply chains. The paper presents the possibilities of evaluation of GSCM performance. The major challenges and obstacles are presented and assessed.(original abstract)

nr nr 4

The paper is the second one of publications on the EPC theory. Relationships between transitions and activity transition units, as well as definitions of functional and control transitions of the framework EPC system, have been presented in it. Then classification of transitions by their attribution to different functional layers and data processing phases in EPC systems has been shown. The resource inputs and outputs have been defined for functional and control transitions. System couplings, as well as input and output resource couplings, between functional and control transitions have been defined by analogy of correspondingcouplings between functional and control units. Tight relationships between structures of an enterprise management system and a corresponding information system have been presented. These are relationships between the structure of associations of functional and control units with information places and the structure of analogous associations of transitions with places. Next, couplings of central coordination transition with local transitions of horizontal coordination have been discussed. On these grounds the notion of a distributed process has been introduced and the definition of a business process has been specified.

Podstawowym zadaniem logistyki jest zapewnienie zasobów niezbędnych do realizacji działania podstawowego w przedsiębiorstwie. Na pierwszy rzut oka cel ten wydaje się być oczywisty, jednak biorąc pod uwagę różnorodność zasobów oraz sposobów ich zapewniania, zadanie to okazuje się sprawą bardzo złożoną. Przedmiotem działań logistycznych są zasoby nie tylko w postaci surowców czy wyrobów gotowych, lecz tak- że informacja, zasoby ludzkie czy finansowe. (fragment tekstu)

The goal of this article was to create the reference model for optimization process in the business logistics. To design the model the author used the architecture of integrated information systems - ARIS due to its ordering properties. Selection of the article's goal resulted from the author's beliefs about the usefulness of these models and their insufficient use in the logistic practice.(original abstract)

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.(original abstract)
