Cost Management in the Public Sector: Legitimation Behaviour and Relevant Decision Making

2016

This paper presents a case study where a cost management project was implemented using action research methodology at two Finnish organizations working in a purchaser–provider relationship. While the study demonstrates the efficiency-seeking motive behind the implementation of the management accounting tool, subsequent investigation found that tool remained partly unused despite showing its potential relevance for practice through user involvement. However, this does not necessarily signal legitimation-seeking behaviour. Reasons for not using some parts of the tool point to an overestimation of the functionality and an underestimation of implementation problems during the design process. Th…

And Now for Something Completely Different: Running Lisp on GPUs

2018

The internal parallelism of compute resources increases permanently, and graphics processing units (GPUs) and other accelerators have been gaining importance in many domains. Researchers from life science, bioinformatics or artificial intelligence, for example, use GPUs to accelerate their computations. However, languages typically used in some of these disciplines often do not benefit from the technical developments because they cannot be executed natively on GPUs. Instead existing programs must be rewritten in other, less dynamic programming languages. On the other hand, the gap in programming features between accelerators and common CPUs shrinks permanently. Since accelerators are becomi…

DEXML: A First Step Toward a UML Based Implementation Framework for PLCS

2011

Data exchange specifications not only must be broad and general to achieve acceptance, but also must be customizable in a controlled and interoperable manner to be useful. The Product Life Cycle Support (PLCS) suite of data exchange specifications (known as DEXs) uses templates to enable controlled customizability without sacrificing breadth or interoperability. DEXs are business context-specific subsets of ISO 10303 Application Protocol (AP) 239, subject to additional constraints imposed by the templates. A PLCS template defines how AP239 entities and their attributes will be instantiated using an externally-defined controlled vocabulary defined in a Reference Data Library. Template instan…

XML Integration and Toolkit for B2B Applications

2003

This paper presents a Web-based data integration methodology and tool framework, called X-TIME, for the development of business-to-business (B2B) design environments and applications. X-TIME provides a data model translator toolkit based on an extensible metamodel and XML. It allows the creation of adaptable semantics oriented metamodels to facilitate the design of wrappers or reconciliators (mediators) by taking into account several characteristics of interoperable information systems such as extensibility and composability. X-TIME defines a set of meta-types for representing meta-level semantic descriptors of data models found in the Web. The meta-types are organized in a generalization h…

From Requirements to Code in a Model Driven Way

2010

Though there is a lot of support for model driven development the support for complete model driven path from requirements to code is limited. The approach proposed in this paper offers such a path which is fully supported by model transformations. The starting point is semiformal requirements containing behaviour description in a controlled natural language. A chain of models is proposed including analysis, platform independent and platform specific models. A particular architecture style is chosen by means of selecting a set of appropriate design patterns for these models. It is shown how to define informally and then implement in model transformation language MOLA the required transforma…

Statechart-based design controllers for FPGA partial reconfiguration

2015

Statechart diagram and UML technique can be a vital part of early conceptual modeling. At the present time there is no much support in hardware design methodologies for reconfiguration features of reprogrammable devices. Authors try to bridge the gap between imprecise UML model and formal HDL description. The key concept in author's proposal is to describe the behavior of the digital controller by statechart diagrams and to map some parts of the behavior into reprogrammable logic by means of group of states which forms sequential automaton. The whole process is illustrated by the example with experimental results.

Comparing the Control-Flow of EPC and Petri Net from the End-User Perspective

2005

This contribution describes the results of a laboratory experiment which compares the Event-driven Process Chain (EPC) and Petri net (C/E net) regarding their approaches to represent the control-flow of processes. The outcome of the experiment indicates that from end-user perspective the EPC approach of applying connectors is superior to the token game. However, the non-local semantic of the EPC OR-connector clearly had a negative impact on end-user comprehension. The experiment also illustrates that the perceived ease-of-use and the intention to use the EPC notation is higher than C/E net.

Biznesa procesu modelēšana, izmantojot metamodelēšanas paņēmienus : kopsavilkums

2007

Darba tēma ir saistīta ar biznesa procesu vadības sistēmu izstrādi. Šajā darbā biznesa procesu modelēšanas problēmas ir risinātas, izmantojot metamodelēšanas paņēmienus. Metamodelēšana ļauj dažādus biznesa modelēšanas aspektus aplūkot vienotā un vispārīgā formā, tai pat laikā nezaudējot precīzu jēdzienu nozīmi. Galvenie pētījumu rezultāti ir sekojoši: Izstrādāts vienots biznesa procesu un to apkārtnes metamodelis, kas parāda biznesa modelēšanas jēdzienus un to saistību. Izstrādāta biznesa modeļu jēdzienu kartēšanas metode jēdzienu kartēšanai no viena domēna uz vairākām modelēšanas valodām. Izstrādāta precīza Unified Modeling Language Aktivitāšu diagrammas (UML AD) izpildes semantika, izmant…

The long and winding road: Accidents and tinkering in software standardization

2021

Software is based on universal principles but not its development. Relating software to hardware is never automatic or easy. Attempts to optimize software production and drastically reduce their costs (like in hardware) have been very restricted. Instead, highly-skilled and experienced individuals are ultimately responsible for project success. The long and convoluted path towards useful and reliable software is often plagued by idiosyncratic accidents and emergent complexity. It was expected that software standardisation would remove these sources of unwanted diversity by aiming to controllable development processes, universal programming languages, and toolkits of reusable software compon…
