Data compression : advantages and disadvantages

Results of modelling process and experiments may be useful to analysts, customers and managers. By tracing development of organizational processes, knowledge acquired from m s may be helpful to manage future changes. Thus, m s help organization to make crucial decisions. This is performed by making a query or search function for a certain process and by generating various reports that are accessible to all members of the organization (hauke and Berendes, 2001). Eventually, as hauke and Berendes (2001) describe it, benefit of simulation is improvement of two main fields: decision-making and communication. Simulation enables evaluation of real influence of financial or non-financial decisions on future activity. . Despite of accessibility of m s, organizations usually meet practical problems while trying to model detailed activity or realize changes in nowadays environment, giaglis. These authors propose that problems of modelling and simulation arise due to such reasons as interactions between separate tasks and informal nature of tasks that burden their analysis and documentation. .

What are the advantages and disadvantages of storing

(2003) highlight that the main advantage of simulation modelling is in for its integration of following functions: analysis and assessment of business processes, either in quantitative or qualitative terms; development of to-be models in order to examine what-if scenarios and export to implementation platforms, such. Hauke and Berendes (2001) maintain that business analysts intuitively create and define a business model in graphical way and together with linear managers analyse what-if cases and consider how to reach? This way, business simulation may facilitate decision-making by forecasting sophisticate what-if scenarios, providing reliable way to evaluate similar effects of different decisions and variables, propose hauke and Berendes (2001). (1998) highlight that m s may be used for optimization of business processes. Modelling and simulation help to make better decisions,. To distribute work operations with regard to available resources, to decide about work-schedule or application of certain business rules. For instance, in order to increase capacity, efficiency and airline-passenger service, baa company that owns and runs 7 uk airports, commissioned heathrow Terminal. Baas process designers and analysts used the model to compare various scenarios until they were confident that their design offered the best compromises and met key targets efficiently without wasteful redundancy. The results of the modelling greatly influenced the size and layout, and service point numbers and positioning of Terminal. Besides, baa used the results in negotiations to convince airlines that customer experience expectations would be met without acceding to demands for unnecessary extra capacity (Paragon Simulation, 2008c).

Top managers and other employees. In general, m s technology is usage of models by storing data as database for managerial and technical decisionmaking. Advantages and disadvantages of business process. There are various tools that facilitate gaining clearer picture of nowadays business activities: spreadsheets, tables, graphs and state reports. But all these tools do not allow fully perceiving factors that condition future profitability. As hauke and Berendes (2001) describe, business analysts and linear managers require a flexible instrument, which enables them to build a model and to assess possible future scenarios at the paper same time analysing multi-related actions and their plausible influence on a process. . According to hauke and Berendes (2001 m s support and supplement electronic spreadsheets, On-Line Analytical Processing (olap) tools and risk analysis software, which enables linking both historical data and cause-sequence assumptions related with future activity. Xerox Corporation used m s seeking to optimize use of automatically guided vehicles (AGVs) of its large assembly area, which helped to save about 180,000. The model cost around 13-days to build and deliver (Paragon Simulation, 2008b).

This author proposes, that simulation involves the generation of an artificial history of the system, and the observation of that artificial history to draw inferences concerning the operating characteristics of the real system that is represented. For instance, wedgwood global distribution centre used m s to verify whether their new automated storage and retrieval system would work properly in conjunction with the existing material handling system and to diagnose causes of the possible problems. M s helped Wedgwood to verify a range of ideas including changing process routes, extending conveyors, and changing control logic to rectify the design issues (Paragon Simulation, 2008d). . m s are widely used for optimization of business processes. It is the tool helping managers to make rational plan decisions and thus to protect organization from failures and save the costs. For instance, m s of operation of tesco distribution centre showed that two fewer automatically guided vehicles (AGVs) were needed than indicated by the original spreadsheet calculations a total saving of 160,000 (Paragon Simulation, 2008a). As mentioned above, modelling enables customer to visualize processes because simulation gives breath to them. Dynamic simulation helps customer to analyse what-if scenarios, to estimate costs and to forecast the activity. Animation of processes facilitates forecasting distribution of responsible staff,.

Johnson (2000) highlights that resolution and adequacy is not the same: an adequate model does not necessarily have high resolution and vice versa. The choice of these features depends on aims of. Usually the major aim of m s is to provide quick response for decision-makers of the organization and a common picture of organization for specialists of know-how creation. Business simulation is a flexible tool that may be used in various fields of businesses (e.g. Financial planning, risk management, forecasting and business process modelling) both at operational and strategic levels. Business simulation involves competitive strategy, management of product portfolio, services and after-purchase services, human resources planning, pricing, financial forecasting as well as investment planning (hauke and Berendes, 2001). . Simulation is the imitation of the operation of a real-world process or system over time. According to banks (2000 it may be adapted to short-term and long-term scenarios, such as analysis of long-term situations (e.g. Market simulation) or concrete cases (e.g.

According to Smith (2000 simulation is the process of designing a model of a real or walk imagined system and conducting experiments with that model. The purpose of simulation experiments is to understand the behaviour of the system or evaluate strategies for the operation of the system (Smith, 2000). Iansiti (1998) highlights that modelling and simulation (M S) do not act isolated: technological and non-technological factors are closely integrated and act in common. Modelling alone may not reveal sufficient information about the processes (Barjis, 2008). M s may be considered as endeavour to imitate real processes and infrastructure (Stanford and Snead, 2000). Most of simulation tools are designed as interactive tools to be used by a human planner not as real time decision-making tools, which are directly linked to control system to dispatch tasks.

Simulation tools aid human planner to make a right decision by providing information. However, human planner should be able to interpret and modify the plan in order to achieve most precise results (Chang and makatsoris, 2001). . Analysing m s, it is important to take into account adequacy and resolution which are main features of. Adequacy may be considered as precision of model in comparison with real world. Model or simulation is adequate if it exactly corresponds or reflects object or experience. Resolution is used for representing aspects of real world in a model or simulation; it may be described as degree of particularity and accuracy (Stanford and Snead, 2000). .

The conditions for the introduction of simulation modelling into process modelling can be summarized as follows (Pidd cited by Indihar-Stemberger., 2003 and by Greasley, 2004 dynamic process behaviour varies over time. Interactive process consists of a number of components which interact with each other. Complicated process consists of many interacting and dynamic objects. As most organizational systems have these characteristics and thus simulation would seem to be an ideal tool for providing information on the behaviour of an organization (Greasley, 2004). In Banks (2000) opinion, simulation is an indispensable problem-solving methodology for the solution of many real-world problems.

According to this author, simulation is used to describe and analyse the behaviour of a system, ask what-if questions about the real system, and aid in the design of real systems. Banks (2000) maintains that both existing and conceptual systems can be modelled with simulation. . Barjis (2008) emphasize that business process modelling and simulation play a significant role in studying, analyzing, optimizing, comparing different scenarios, and measuring the effects in advance. This researcher agrees that simulation is a safe and inexpensive way of studying the impact of changes and revealing hidden behaviours of a complex system. . Business process simulation means execution of model. Simulation may be defined as a collection of methods and applications to imitate the behaviour of real systems (Aguilar-savén, 2004).

This tool, according to Sparks (2000 involves the following elements: primary (input) data, defined results, used resources, tasks which are fulfilled in certain order as well as factors influencing the process. Design decisions of business process model (according to gordijn., 2000). Business process model is devoted to specification of causal and conditional links between business operations, barjis and Ilkov (2004) propose. These authors maintain that causal link is a link between two business operations when one operation type causes beginning of another operation, while conditional link is a link where the end of one operation determines start or end of another operation. Both, causal and conditional links are optional,. E., start of a new business operation depends on certain conditions. (2003) highlight that many different methods and techniques can be used for modelling business processes in order to give an understanding of possible scenarios for improvement. The simulation modelling shows the process as a whole, drawbacks of the existing process, bottlenecks in the process execution and provides critical insight into process execution.

Meanwhile business process modelling ensures creation of a common approach for work to be carried out; incremental improvement of processes (e.g. Efficiency support of processes by workflow management systems; as well as analysis of properties of a process (Gordijn., 2000). To present the how, a business process model typically shows the design decisions displayed in Figure. Referring to patel and Hlupic (2000 business process modelling is a technique used to analyse and model business processes. Sparks (2000) proposes restaurant that business process modelling allows fixing main principles and procedures, describing how business is organized. Besides, modelling enables customer to visualize processes. It helps understanding operational links and impact of interactions. It is evident that business process model should be a flexible, customized and accessible tool (Bahrami., 1998).

and full capacity of enterprise modelling and simulation still have yet to be revealed. . Despite bunch of evident advantages, some authors describe difficulties related to implementation of modelling and simulation in practice. These are related to heavy time and money consumption as well as with reliability of models. Essence of business process modelling and simulation (M S). Magretta (2002) defines business modelling as a managerial equivalent of the scientific method: hypothesis which is tested in action and raised when necessary. According to gordijn. (2000 the main goal of a business model is to answer the question: who offers what to whom and what expects in return. Therefore, these authors emphasise concept of value, which, they propose, should be the central notion in any business model explaining the creation and addition of value in a multi-party stakeholder network, as well as the exchange of value between stakeholders. The researchers agree that a business model does not state how value-creating activities are carried out.

Thus, the aim of the article is to contrast main advantages and disadvantages of business process modelling and simulation, and to assess usage of m s in planning of business processes. The article overviews and sums-up opinions of Chang and makatsoris (2001 johnson (2000 Brown. (2000 gould (2000 giaglis. (2004 banks (2000 Greasley (2004) and other researchers; and supports the findings with practical examples on how implementation of m s has helped to improve business processing of huge transnational corporations. Introduction, increasing competition, growing customer requirements, shift of technologies and other rapid market changes push businesses into higher risk and may invoke serious consequences for them. Therefore organizations should look for ways how to diminish business risk. Barjis (2008) maintains friend that the recursive activities of adapt-change-improve would be a driving force for the 21st century enterprises; therefore business process modelling and simulation might be a crucial tool for assessing business cording to perumpalath (2005 an organisation may be considered as a complex. Business process change involves changes in people, processes and technology (Indihar-Stemberger., 2003).
