Generation of User Interfaces from Business Process Model Notation (BPMN)

2019

Business Process Model Notation focuses on functional processes; so, the design of the interface generally depends on the subjective experience of the analyst. This thesis proposes a new method to generate interfaces from BPMN models. The idea is to identify rules from BPMN to interfaces in existing real projects. We have analyzed 7 Bizagi projects to generalize a list of rules. It has been done considering five BPMN patterns. Apart from BPMN primitives, there are rules that depend on elements of Class Diagrams to know how to generate the interfaces. When the rules have several alternatives to generate the interfaces, we need an unambiguous semantics to specify which alternative we are goin…

Determinants to the Use of Business Process Modeling

2010

This article addresses a theoretical gap in the BPM literature on factors that influence the acceptance of process modeling (PM) in organizations. Literature review on PM and 34 qualitative interviews were combined into a PM acceptance model and empirically tested with data from 74 companies showing that PM is to a large extent a mandated activity, explaining the missing link between PM attitudes on PM intention. The study extends the TAM and the TPB to the context of process modeling and demonstrates that less studied socio-political factors in addition to awareness of PM are important to understand PM acceptance. The findings show that social influence from different stakeholder reference…

Batch fermentation process: Modelling and direct sensitivity analysis

2009

Based on a nonlinear model, this article realizes an investigation of dynamic behaviour of a batch fermentation process using direct sensitivity analysis (DSA). The used nonlinear mathematical model has a good qualitative and quantitative description of the alcoholic fermentation process. This model has been discussed and validated by authors in other studies. The DSA of dynamic model was used to calculate the matrix of the sensitivity functions in order to determine the influence of the small deviations of initial state, control inputs, and parameters from the ideal nominal values on the state trajectory and system output in time. Process optimization and advanced control strategies can be…

Models of Event Driven Systems

2016

This paper provides the business process modeling approach based on usage of Domain Specific Languages (DSL). The proposed approach allows us to create executable information systems’ models and extends the concept of Event Driven Architecture (EDA) with the business process execution description. It lets us apply principles of the Model Driven Development (MDD) in order to create the information system which complies with the model. The proposed approach provides a set of advantages in information systems development, use and maintenance: bridges the gap between business and IT, an exact specification, which is easily to implement into information system, up-to-date documentation etc. The …

Identification of a static tool force model for robotic face milling

2014

In this paper two different process models which can predict the mean value components of the tool forces when milling aluminium, bronze and steel with an industrial robot have been estimated. The parameters in the process models were depth and width of cut, while feedrate and cutting speed were found from the tool manufacturer's datasheets. The models were estimated from a large set of machining experiments. Different measurement sets were used for parameter estimation and for model verification. The estimated models were found to be accurate. For the experiments in aluminium and the model using only the depth of cut as parameter, the average error was about 18N. For the model using both d…

Business Process-oriented design of Enterprise Resource Planning (ERP) systems for small and medium enterprises

2006

In the last few years, many organizations have used business process modelling as an effective tool for managing organizational changes. However, process modelling has rarely been exploited for supporting the entire business process management life cycle. This includes the design of business processes as well as their implementation and control. The adoption and implementation of Enterprise Resource Planning (ERP) systems is a crucial issue if referred to small and medium-sized enterprises. The main problem is that the cost of implementation of ERP, intended as the process of customization of the ERP system towards the actual enterprise business processes, overtakes the cost of ERP acquisit…

Analysis, Modeling and Simulation of Complex Regional Clusters Activities, Using Arena Simulation Software

2014

Process modelling is the concise description of the total variation in one quantity, y, by partitioning it into a deterministic component given by a mathematical function of one or more other quantities, x1, x2... plus a random component that follows a particular probability distribution. The models are material or immaterial systems, which represent other systems, so that it may be possible to manipulate the built structures and their states. The main elements of a simulation are: attributes (describe and differentiate entities), variables (system characteristics), resources (whose capacity can be variable), tails (seen in case of unavailability of resources) and statistical accumulators (…

Semantics of UML 2.0 Activity Diagram for Business Modeling by Means of Virtual Machine

2005

The paper proposes a more formalized definition of UML 2.0 Activity Diagram semantics. A subset of activity diagram constructs relevant for business process modeling is considered. The semantics definition is based on the original token flow methodology, but a more constructive approach is used. The Activity Diagram Virtual machine is defined by means of a metamodel, with operations defined by a mix of pseudocode and OCL pre- and postconditions. A formal procedure is described which builds the virtual machine for any activity diagram. The relatively complicated original token movement rules in control nodes and edges are combined into paths from an action to action. A new approach is the us…

Commercial and financial policies in family firms: The small business growth management flight simulator

2000

An interactive learning environment (ILE) was built to reproduce the budgeting process of a small family-owned entrepreneurial firm and to capture how current decisions affect business growth in a longer time horizon. The ILE matches the accounting-related perspective through which spreadsheet-based budgets are drawn up, with the system dynamics (SD) view. Such a goal has been pursued through a connection of traditional Excel spreadsheets with POWERSIM SD models. Playing the SMALL BUSINESS GROWTH MANAGEMENT FLIGHT SIMULATOR allows one to learn how (a) to draw up a budget based on an SD perspective, (b) long-term goals may be affected by current decisions, (c) business/family survival and gr…
