The Difference ◽  
Manipulation Process

Googling the term “Business Process Simulation” in April 2013 yielded only 42.1 thousand hits. It is not much compared with googling the term such as “Business Process Modelling” in the same time, which yielded approx. 1.470 million hits. That is 35 times more compared to the previous search. The difference between modelling and simulation is arguable. In fact, the terms ‘simulation’ and ‘modelling’ are often used synonymously, but the authors prefer to distinguish between the terms and look at modelling as an act of building a model while simulation is considered an act or even a process of using that model for a specific purpose or study. If simulation is a manipulation process of one or more variables, which can be changed and observed, then this kind of process is best managed and controlled by business rules that can also be manipulated in the simulation process. „Google“ paieškoje įvestas terminas „Business Process Simulation“ 2013 metų balandžio mėn. duoda tik 42,1 tūkst. paieškos rezultatų. Tai nėra daug, palyginti su kitu paieškos terminu „Business Process Modelling“. Tuo pačiu metu reikšminiai paieškos žodžiai duoda apie 1,470 milijono paieškos rezultatų. Tai 35 kartus daugiau, palyginti su prieš tai daryta paieška. Galima ginčytis, ar yra skirtumas tarp modeliavimo ir simuliavimo? Iš tiesų žodžiai „modeliavimas“ ir „simuliavimas“ dažnai vartojami kaip sinonimai, tačiau straipsnyje siūloma į modeliavimą ir simuliavimą žiūrėti skirtingai, t. y. į modeliavimą kaip į veiksmą, kuris sukuria modelį, į simuliavimą – kaip į veiksmą arba procesą, kuris sudaro sąlygas taikyti šį modelį konkrečiam tikslui arba tyrimui atlikti. Jeigu apibrėžiama, kad simuliavimas yra vieno ar daugiau kintamųjų manipuliacijos procesas, kurį galima pakeisti ir stebėti, tada taip pat galima susitarti, kad šis procesas geriausiai grindžiamas verslo taisyklėmis, kurios gali būti papildomos arba keičiamos simuliavimo proceso metu.

Proper Analysis

Looking for ways to increase operational efficiency, more and more companies focus on process evaluation. A proper analysis of process weaknesses can reveal activities in need of improvement. In order to choose a business process modelling tool that meets user needs, every tool has to be evaluated according to different criteria. Business rules are an integral part of business and the authors propose evaluating business process modelling tools using a new criteria set: capabilities of work with business rules. Straipsnyje analizuojamas verslo procesų modeliavimo priemonių, gebančių vykdyti verslo procesų simuliavimą, vertinimo kriterijų karkasas ir vertinimo kriterijai. Siūloma išplėsti verslo procesų modeliavimo priemonių vertinimo kriterijų karkasą papildoma vertinimo kriterijų grupe – darbo su verslo taisyklėmis galimybėmis. Pasiūlyti kriterijai naudojami pasiren­kant vartotojo poreikius atitinkančią verslo procesų modeliavimo ir simuliavimo priemonę.

Purpose Changing scattered and dynamic business rules in business workflow systems has become a growing problem that hinders the use and configuration of workflow-based applications. There is a gap in the existing research studies which currently focus on solutions that are application specific, without accounting for the universal logical dependencies between the business rules and, as a result, do not support adaptation of the business rules in real time. The paper aims to discuss this issue. Design/methodology/approach To tackle the above problems, this paper adopts a bottom-up approach, which puts forward a component model of the business process workflows and then adds business rules which have clear logical semantics. This allows incremental development of the workflows and semantic indexing of the rules which govern them during the initial acquisition. Findings The paper introduces an event-driven model for development of business workflows which is purely logic-based and can be easily implemented using an object-oriented technology, together with a model of the business rules dependencies which supports incremental semantic indexing. It also proposes a two-level inference mechanism as a vehicle for controlling the business process execution and the process of adaptation of the business rules at real time based on propagating the dependencies. Research limitations/implications The framework is strictly logical and completely domain-independent. It allows to account both synchronous and asynchronous triggering events as well as both qualitative and quantitative description of the conditions of the rules. Although our primary interest is to apply the framework to the business processes typical in the construction industry we believe our approach has much wider potential due to its strictly logical formalization and domain independence. In fact it can be used to control any business processes where the execution is governed by rules. Practical implications The framework could be applied to both large business process modelling tasks and small but very dynamic business processes like the typical digital business processes found in online banking or e-Commerce. For example, it can be used for adjusting security policies by adding the capability to adapt automatically the access rights to account for additional resources and new channels of operation which can be very interesting ion both B2C and B2B applications. Social implications The potential scope of the impact of the research reported here is linked to the wide applicability of rule-based systems in business. Our approach makes it possible not only to control the execution of the processes, but also to identify problems in the control policies themselves from the point of view of their logical properties – consistency, redundancies and potential gaps in the logics. In addition to this, our approach not only increases the efficiency, but also provides flexibility for adaptation of the policies in real time and increases the security of the overall control which improves the overall quality of the automation. Originality/value The major achievement reported in this paper is the construction of a universal, strictly logic-based event-driven framework for business process modelling and control, which allows purely logical analysis and adaptation of the business rules governing the business workflows through accounting their dependencies. An added value is the support for object-oriented implementation and the incremental indexing which has been possible thanks to the bottom-up approach adopted in the construction of the framework.

Purpose – The purpose of this paper is to provide a method for analysing and improving the operational performance of business processes (BPs). Design/methodology/approach – The method employs two standards, Business Process Modelling Notation (BPMN 2.0) and Business Processes Simulation (BPSim 1.0), to measure key performance indicators (KPIs) of BPs and test for potential improvements. The BP is first modelled in BPMN 2.0. Operational performance can then be measured using BPSim 1.0. The process simulation also enables execution of reliable “what-if” analysis, allowing improvements of the actual processes under study. To confirm the validity of the method the authors provide an application to the healthcare domain, in which the authors conduct several simulation experiments. The case study examines a standardised patient arrival and treatment process in an orthopaedic-emergency room of a public hospital. Findings – The method permits detection of process criticalities, as well as identifying the best corrective actions by means of the “what-if” analysis. The paper discusses both management and research implications of the method. Originality/value – The study responds to current calls for holistic and sustainable approaches to business process management (BPM). It provides step-by-step process modelling and simulation that serve as a “virtual laboratory” to test potential improvements and verify their impact on operational performance, without the risk of error that would be involved in ex-novo simulation programming.

Insight Into

All companies have business processes, regardless of the size or the industry in which they operate. Both executive and operational managers need insight into software-based business processes and their performance for that transforming business workflows by modeling, simulating,  optimizing, and publishing processes and defining business rules. I would like to introduce what kind of possibility the companies have got, when they want to model their business process. I choose the ARIS system from software market. I sketch out the function of ARIS system, and his application possibility. At last I present the best known diagram by means of some practical example.
