The Impact

Research background: Managerial scientists use a lot of modelling techniques for business processes. In this paper we are focused on agent-based modelling and simulations, which emerged in the last two decades as a new approach. Autonomous and interacting intelligent agents are able to model and simulate complex systems in the business sphere. With the use of agent-based modelling and simulations we are able to understand how macro level outcomes are affected by micro level processes and vice versa.Purpose of the article: The purpose of the paper is to introduce recent development in the area of agent-based modelling and simulations focused on the business domain. Managers often have to make difficult decisions under the uncertainty and high risks. Agent-based modelling can provide powerful tools for lowering those risks through a possibility of running experiments, which is normally impossible in economics. In the second part we want to support the usefulness of agent-based simulations with our own simulations.Methods: The method used in this article is an agent-based simulation in a multi-agent system. We use a framework called MAREA. It is a simulation environment with integrated ERP system based on REA ontology. Our simulation model is based on a retail company that sells electronics. For simplicity, in our setup we trade with computer cables.Findings & Value added: In our simulations we experimented with the quality of sales service provided by company’s sales representatives. We investigated the impact of quality of sales service on company KPIs under the changing environment circumstances represented by disturbance agent. The quality of sales service is a part of quality of service and thus it affects the perception of brand and loyalty of customers towards the company. In our simulation setup we work with two types of customers, long-term customers and new ones. The result is that quality of sales service has mostly positive effects on company KPIs.

The Impact

The goal of this research was to investigate the possibility of using Agent-based Modelling, a novel approach in computerized simulation, to assess the effects of staff ratio on recovery time and to develop an empirical research plan based on an inpatient unit. By creating a virtual unit, the researcher was able to develop an adjustable model to test several scenarios based on empirical evidence; to comprehend the impact of changes to staff ratio and patient acuity on nurses’ workload and quality of care to patients. This investigation found that acuity indices of patients have no significant effect on available recovery time or the number of unperformed activities. On the contrary, nurse/patient ratio has substantial effects on both available recovery time and the number of unperformed activities; which asserts the significant effect of insufficient nurse staffing on the well-being of nurses as well as quality of care to patients.

The Impact

State policy makers are constantly looking for ways to improve teacher quality. An oft tried method is to increase the rigor of licensure exams. This study utilizes state administrative data from Arkansas to determine whether raising the cut-scores on licensure exams would improve the quality of the teacher workforce. In addition, the study explores the trade-offs of such a policy decision. It is concluded that raising the required passing score on the Praxis II would increase the quality of the teacher workforce, as measured by value-added student achievement. This change, however, would be accompanied with an important trade-off as it would reduce the number of minority teachers and potentially lead to negative outcomes in disadvantaged schools.

Agent-based modelling provides a mechanism by which complex social phenomena can simulated in order to identify how particular features arise from causes such as demographics, human preferences and their interaction with policy settings. The NetLogo environment has been used to implement a simulation of the New Zealand higher education system, using historical data to calibrate model settings to mirror those of the real-world system. This simulation is used to explore how the introduction of an alternative qualification and education paradigm might disrupt established patterns of education and employment.

Background The Västerbotten intervention program (VIP), is a public health promotion program in northern Sweden with the aim of preventing cardiovascular disease. Positive effects have been reported although the evidence is not unequivocal. Since only historical controls have been used, effects from other sources than the program have largely been uncontrolled for and health related quality of life (HRQoL) has not been evaluated. Purpose By using the neighbouring county of Norrbotten (NB) as the reference population, we compare HRQoL in Västerbotten (VB) and in NB. Methods In 2014 the Northern Sweden survey, Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA), examined a random sample from the two counties. HRQoL was measured with the EQ-5D-3L. In total, 1112 subjects aged 40–74 years participated, 516 in VB and 594 in NB. Differences in mean QoL between VB and NB were analysed via Student’s t-test and the Pearson chi-square test. Results Average HRQoL measured by the EQ-5D-index was 0.798 in VB and 0.811 in NB, a difference of 0.013 (p = 0.2, CI -0.009 to 0.036). For subjects aged 45–54 years, the HRQoL was lower in VB than in NB, a difference of 0.048 (p = 0.041; CI 0.002 to 0.0094). Men had higher HRQoL than women, and university educated had higher HRQoL than those without university education. EQ-VAS showed similar results. Subjects from NB and from VB did not differ regarding age, gender and level of education. In NB, HRQoL decrease with age, a pattern not seen in VB. Conclusions We found similar levels of HRQoL in VB and in NB.

AbstractBackground and Purpose: Agent-based modelling and simulation (ABS) is growing in many areas like, e.g., management, social and computer sciences. However, the similar trend does not seem to occur within the field of business process management (BPM), even though simulation approaches like discrete event simulation or system dynamics are well established and widely used. Thus, in our paper we investigate the advantages and disadvantages of agent-based modelling and simulation in the field of BPM in simulation experiments.Design/Methodology/Approach: In our research, we investigate if there is a necessity for ABS in the field of BPM with our own simulation experiments to compare traditional and ABS models. For this purpose, we use simulation framework MAREA, which is a simulation environment with integrated ERP system. Our model is a complex system of a trading company selling computer cables. For the verification of our model, we use automated process discovery techniques.Results: In our simulations, we investigated the impact of changes in resources’ behavior on the outcome of company’s order to cash process (O2C). Simulations experiments demonstrated that even small changes might have statistically significant effect on outcomes of the processes and decisions based on such outcomes. Simulation experiments also demonstrated that the impact of randomly distributed fluctuations of well-being have a diminishing tendency with the increasing number of sales representatives involved in the process.Conclusions: Our research revealed several advantages and disadvantages of using ABS in business process modelling. However, as we show, many of them were at least partially addressed in the recent years. Thus, we believe that ABS will get more attention in the field of BPM similarly to other fields like, e.g., social sciences. We suggested areas in BPM simulations, e.g., modelling of resources, be it human or technological resources, where there is a need for ABS.

The Impact

Research background: Public procurement is designed to efficiently spend public sector financial resources. This should lead to savings in public funds. Domestic and foreign studies point to the fact that sufficient competition on the supply side is the condition for achieving those savings. Slovakia currently belongs to a group of countries with low competition on the supply side of the tender. Every year, about 10,000 tenders will be made in Slovakia for 5 billion Eur. However, contracting authorities have difficulty with establishing the estimated contract value and defining non-discriminatory criteria. On the other hand, contractors lack the expertise to prepare tenders, specifications are often tailored to specific bidders or products, and the price criterion has a negative impact on the quality of the goods and services purchased. Purpose of the article: The aim of the study was to investigate the impact of selected efficiency determinants on savings in public procurement in Slovakia in 2010–2016. The number of bids, the subcontractor's participation, the narrower competition and the impact of the narrower competition and the expected price on the number of bids have been examined. Methods: The survey sample consisted of 800 randomly selected public procurement con-tracts from different sectors in 2010–2016. The contracts were split on the basis of the median estimate of the above-limit (409 contracts) and below-limit (391 contracts) contracts; the divestment value was the estimated price of 400,000 Euro (without the tax). Findings & Value added: The number of offers positively influences the creation of savings in public procurement, an average of 5-6%. The impact of a narrow competition was significant, which led to a decrease in savings of 3-4% compared to the open competition if the sample was 800 contracts and over 400,000 Euro (without the tax). For below-limit orders, this determinant was shown to be statistically insignificant. The size of the contract did not affect the number of successful candidates. Also, the negative impact of narrower competition on the number of tenders was demonstrated. These findings are in line with the presented research studies. In the future, we plan to perform sectoral analyses to verify the validity of the hypotheses under review based on the results of our research.
