Like manufacturing companies that have flowshop production lines, SME facing the amount of flow time and makespan. Unfulfilled production targets, buildup on some machines that result in other machines being idle, increasing waiting times across multiple machines, and poor performance of workers are a series of problems facing SME. This article uses a discrete system simulation method to analyze and evaluate SME production lines to improve performance. Simulation is an appropriate tool used when experiments are needed in order to find the best response from system components. From the results of modeling and simulation done found the root of the problem is due to accumulation that occurs in one machine and the lack of utility of the operator in producing bags. So do the experimental design with 3 scenarios on the system that have been modeled and obtained some solutions that can be offered to solve the problem. Furthermore, after the alternative selection is obtained the best scenario based on the alternative selection test is the scenario3 by adding 2 new machines and 1 new operator on the production line obtained a significant output increase compared to other scenarios of approximately 30%. While the best scenario based on the minimum cost is the scenario2 by adding 2 new operators obtained output that is not much different than the scenario3. However, it has not been able to solve a series of problems facing SME. Therefore, the results of this study to solve a series of problems faced by SME is to add facilities in the production line of 2 new machines and 1 operator (scenario3).

Designing district-scale energy systems with renewable energy sources is still a challenge, as it involves modeling of multiple loads and many options to combine energy system components. In the current study, two different energy system scenarios for a district in Montreal/Canada are compared to choose the most cost-effective and energy-efficient energy system scenario for the studied area. In the first scenario, a decentral energy system comprised of ground-source heat pumps provides heating and cooling for each building, while, in the second scenario, a district heating and cooling system with a central heat pump is designed. Firstly, heating and cooling demand are calculated in a completely automated process using an Automatic Urban Building Energy Modeling System approach (AUBEM). Then, the Integrated Simulation Environment Language (INSEL) is used to prepare a model for the energy system. The proposed model provides heat pump capacity and the number of required heat pumps (HP), the number of photovoltaic (PV) panels, and AC electricity generation potential using PV. After designing the energy systems, the piping system, heat losses, and temperature distribution of the centralized scenario are calculated using a MATLAB code. Finally, two scenarios are assessed economically using the Levelized Cost of Energy (LCOE) method. The results show that the central scenario’s total HP electricity consumption is 17% lower than that of the decentral systems and requires less heat pump capacity than the decentral scenario. The LCOE of both scenarios varies from 0.04 to 0.07 CAD/kWh, which is cheaper than the electricity cost in Quebec (0.08 CAD/kWh). A comparison between both scenarios shows that the centralized energy system is cost-beneficial for all buildings and, after applying the discounts, the LCOE of this scenario decreases to 0.04 CAD/kWh.

<p>Horticultural commodities, in Indonesia, are one of the main clusters of export commodities. The demand of the commodities is relatively high due to the high economic level of consumers in Singapore. The exporter, e.g., PT BSL, had difficulties to meet the demand of Singapore’s importer. This problem will be analyzed with inventory system in the supply chain of vegetables and fruits exported from Central Java Indonesia to Singapore. To identify the problem, we combine a dynamic system approach and its validation. The data on existing conditions (with the level of rejection = 20%) were then formulated and modeled with two alternative scenarios, scenario1 and 2. In scenario 1, the level of rejection was set at the level of 10%, while scenario2 at the level of 30%. Based on the simulation results, it was found that the average level of inventory in the scenario 1 was at 661.9 kg per day, while in scenario 2 were 112.34 kg per day.</p><p><strong>Keywords</strong>: dynamic systems, horticultural commodities, inventory, supply chain </p>

Biogas production from organic by-products is a way to recover energy and nutrients. However, biogas production is not the only possible conversion alternative for these by-products, and hence there is interest in studying how organic by-products are treated today and which alternatives for conversion are the most resource efficient from a systems perspective. This paper investigates if biogas production is a resource efficient alternative, compared to business as usual, to treat food industry by-products, and if so, under what circumstances. Five different cases of food industries were studied, all with different prerequisites. For all cases, three different scenarios were analysed. The first scenario is the business as usual (Scenario BAU), where the by-products currently are either incinerated, used as animal feed or compost. The second and third scenarios are potential biogas scenarios where biogas is either used as vehicle fuel (Scenario Vehicle) or to produce heat and power (Scenario CHP). All scenarios, and consequently, all cases have been analysed from three different perspectives: Economy, energy, and environment. The environmental perspective was divided into Global Warming Potential (GWP), Acidification Potential (AP), and Eutrophication Potential (EP). The results show, in almost all the systems, that it would be more resource efficient to change the treatment method from Scenario BAU to one of the biogas scenarios. This paper concludes that both the perspective in focus and the case at hand are vital for deciding whether biogas production is the best option to treat industrial organic by-products. The results suggest that the food industry should not be the only actor involved in deciding how to treat its by-products.

Supply chain management integrates the entire business process of a product from upstream to downstream with the aim of delivering products to consumers in a timely manner and precise quantity without overriding profit. The application of dynamics systems is aimed to provide a holistic view of the system and to identify how interrelationship affects the system as a whole. System dynamics approach is used to analyze the efforts to improve performance. Besides being used as an analysis related to the model, system dynamics can also be used to formulate effective policy related to the profit distribution in case study of bell pepper supply chain. In this study, several scenarios were used as references to improve bell pepper supply chain performance in Regency X. The stake holders in the supply chain were farmer, middleman, and wholesaler. There were three sub-models used in system dynamics, namely the sub-model farmer, middleman, and wholesaler. The model in the system dynamics was then developed to find out the best scenario in improving the performance of bell pepper supply chain. The scenario developed consisted of 4 scenarios in which scenario 1 became the basic scenario as the comparison of simulation results. Then, Scenario 2 was a Supply-Demand arrangement to reduce losses obtained at the level of middleman and wholesaler. The policy of Scenario 3 was warehouse procurement, which was a model improvement scenario in Scenario 3. Lastly, Scenario 4 was an increase in the level of demand / market expansion without an increase in the number of production. The highest total supply chain profit from the four scenarios was in Scenario 3, while the lowest was Scenario 2.

Abstract This study aims to understand the long-term (2020–2050) urban water–energy–food (WEF) resources access and sustainability in Addis Ababa city through a nexus modeling approach. Several feasible scenarios in line with improving WEF resources supply and access through conservation, system rehabilitation and technology input are explored. The water system scenarios include rehabilitation and conservation scenario, water supply enhancement scenario, technology input scenario and integrated water improvement scenario. The energy scenario includes energy conservation scenario and new renewable supply enhancement scenarios and integration of both scenarios as integrated energy scenario. The food system scenarios include crop yield productivity and irrigation water use efficiency scenarios of urban agricultural system. The integrated WEF nexus scenario is the integration of all scenarios under one nexus framework. The results are evaluated against baseline scenario. At a system level, the integrated water scenario result provides a water saving potential of 26 and 52% from the baseline scenario by 2030 and 2050, respectively, whereas the integrated energy use scenario saves energy by as much as 22 and 48%. For respective years, under the integrated WEF nexus scenario, the integrated water use scenario for low energy intensity reduces the energy use for urban water system by 23 and 72% from the baseline scenario. Similarly, urban food production have also shown enhancement. Urban food production system in Addis Ababa city is relatively small and does not significantly affect the food import from other parts of the country. Overall, the results WEF nexus modeling approach revealed the importance of exploring integrated nexus approach to sustainable urban water energy and food development and management as a first attempt at the urban scale.

Land use/Land cover (LULC) changes as a result of policy planning influence ecosystem structures, processes, and functions, which are the basis for providing a wide range of ecosystem services (ES). There is an increasing consensus about the importance of integrating ES into ecological policy but quantifying the potential impacts of different policy on ES has proven difficult. We designed a remote sensing, geographic information system and scenario analysis-based approach to estimate and analyze the relationship between ES (soil conservation and carbon sequestration) and ecological policy designed to improve human welfare in the Chongqing municipality in the upper reaches of the Three Gorges Reservoir Area, China; a densely populated, highly modified watershed with serious soil erosion and flood hazard. Three alternative scenarios in 2050 were modeled for the Three Gorges Reservoir Area watershed. The model GEOMOD was used to predict future LULC changes due to policy planning. The ES models (Universal Soil Loss Equation model and Carnegie-Ames-Stanford Approach model) were designed to inform decisions, with an aim to align economic forces with conservation. We examine policy effectiveness by comparing scenarios for 2050 (Scenario1: Maintain current policy with no considerations of ES; Scenario2: Integrate ES into policy planning; Scenario3: Integrate ES into policy planning in view of the need of local people). Scenario-based LULC change analysis revealed that if the current afforestation policy continues (scenario 1), total ES would be further increased in 2050 due to expansion of forest cover. However, by targeting policy to improve ES provision (scenarios 2 and 3), ecological risks of soil loss can be significantly reduced and carbon sequestration enhanced. Scenario 3, thus, provided the best future environmental development scenario considering the need of local people in each region for ES. This scenario will theoretically help the Three Gorges Dam to harvest more ecological benefits through improvements in soil conservation and carbon sequestration. This study highlights the observation that including ES in policy planning and has a great potential to generate opportunities to maximize ES. This study highlights that including ES in policy planning has a great potential to generate opportunities to maximize ES. Hence, there is a need to encourage proper implementation of ecological policy to maintain and improve ES.

The capability planning is a fundamental task when designing a Weapon System of Systems (WSOS). Uncertainties exist when building WSOS. It is difficult to select the most appropriate alternatives under the background of system operations. The programming of capability of WSOS is a multi-criteria decision-making problem. To resolve this problem, a scenario-based multi-criteria decision-making methodology is proposed. Scenario describes the future situation may occur, and also presents the uncertainty of reality. In this paper, scenario was modeled by the key variables in which experts and stakeholders are interested. TOPSIS was also improved based on multiple scenarios. Finally, the method is validated by an example of armored weapon systems.

Predicting a sustainable food safety policy for the near future is among Turkey's priority problems. In this context, this study aims to predict Turkey's sustainable food safety policies. For this reason, the system dynamics model, which is a dynamic cycle-based method with stock and flow diagrams, is used in this paper. This study supposed the six different scenarios for 2020 and 2050. Data were selected as population, productivity rate, arable land fertility rate, and annual food consumption (per capita). The purpose of creating these scenarios; To determine the most appropriate policy to ensure food safety in Turkey. In the first scenario, we assumed that the current situation continues. In the second scenario, the average productivity rate was increased by 1.5%. The third scenario assumes that annual per capita food consumption rises to 1.2 tonnes per year. In the fourth scenario, the total fertility rate is accelerated by 2%. In the fifth scenario, we assumed that the arable land loss rate decreased by 1/3. Finally, we assumed that the sixth scenario covers all the second, third, fourth, and fifth scenarios and that 2 points reduce food losses. In conclusion, the findings show that food security responds positively in scenarios 2 and 6. However, in other scenarios, food security is negatively affected. The findings show that the sixth scenario is the best-case scenario. To ensure food security, it is necessary to reduce arable land losses and food waste. Training farmers and control of the food supply chain will be beneficial for sustainable food security in Turkey. We recommend that policymakers consider these recommendations.

The development of renewable energy represented by wind, photovoltaic and hydropower has increased the uncertainty of power systems. In order to ensure the flexible operation of power systems with a high proportion of renewable energy, it is necessary to establish a multi-scenario power system flexibility evaluation method. First, this study uses a modified k-means algorithm to cluster operating scenarios of renewable energy and load to obtain several typical scenarios. Then, flexibility evaluation indices are proposed from three perspectives, including supply and demand balance of the zone, power flow distribution of the zone and transmission capacity between zones. Next, to calculate the flexibility evaluation indices of each scenario—and according to the occurrence probability of each scenario—we multiplied the indices of each scenario by the scenario occurrence probability to obtain comprehensive evaluation indices of all scenarios. Based on the actual historical output data of renewable energy and load of a southern power system in China, a flexibility evaluation was performed on the modified IEEE 14 system and modified IEEE 39 system. The results show that the proposed clustering method and flexibility indices can effectively reflect the flexibility status of the power system.

Developing training scenarios that induce a trainee to utilize specific skills is one of the facets of simulation-based training that requires significant effort. Simulation-based training systems have become more complex in recent years. Because of this added complexity, the amount of effort required to generate and maintain training scenarios has increased. This thesis describes an investigation into automating the scenario generation process. The Automated Scenario Generation System (ASGS) generates expected action flow as contexts in chronological order from several events and tasks with estimated time for the entire training mission. When the training objectives and conditions are defined, the ASGS will automatically generate a scenario, with some randomization to ensure no two equivalent scenarios are identical. This makes it possible to train different groups of trainees sequentially who may have the same level or training objectives without using a single scenario repeatedly. The thesis describes the prototype ASGS and the evaluation results are described and discussed. SVSTM Desktop is used as the development infrastructure for ASGS as prototype training system.

Software plays a significant role in society. It penetrates every field such as telecommunications, public administration, cooperation management, etc. In a software development life cycle (abbr., SDLC), software testing is a key phase. It accounts for a large part of software development costs. This is a consequence of testing being performed late in an improvised and impromptu way under the discretion of project managers. Continual testing as proposed by the extreme programming approach advocates that automated testing be performed in the early phases of the SDLC. Automation helps avoid disorderly and unsystematic progress of testing tasks and assignments. This thesis presents an approach for the generation of test cases from use cases---a form of requirements used in the early phases of the SDLC. We first needed a way to combine related use cases in order to infer system-level test cases spawning over several use cases. We developed an approach to infer use case sequential relations based on a comparison of pre-conditions and post-conditions. This approach offers the benefit of obtaining use case sequential relations without solely relying on the traditional UML use case relationships (i.e., include, extend and generalization). It helps to avoid the functional decomposition of use cases. We then propose an automated approach for die generation of test scenarios, a step toward complete and concrete test cases. Test scenarios are generated using depth-first traversal of control flow-based state machines obtained from use cases. The construction of these control flow-based state machines considers traditional UML use case relationships as well as inferred sequential relations. Depth-first traversal of control flow-based state machines is controlled by a coverage criterion inspired from traditional white-box code coverage.

This thesis evaluates a method for system security assessment (MASS), developed at the Swedish Defence Research Agency in Linköping. The evaluation has been carried out with the use of scenarios, consisting of three example networks and several modifications of those. The results from the scenarios are then compared to the expectations of the author and a general discussion is taken about whether or not the results are realistic.

The evaluation is not meant to be exhaustive, so even if MASS had passed the evaluation with flying colors, it could not have been regarded as proof that the method works as intended. However, this was not the case; even though MASS responded well to the majority of the modifications, some issues indicating possible adjustments or improvements were found and commented on in this report.

The conclusion from the evaluation is therefore that there are issues to be solved and that the evaluated version of MASS is not ready to be used to evaluate real networks. The method has enough promise not to be discarded, though. With the aid of the issues found in this thesis, it should be developed further, along with the supporting tools, and be re-evaluated.

A crisis is an infrequent and unpredictable event. Training and preparation process requires tools for representation of crisis context. Particularly, crisis events consist of different situations, which can occur at the same time combining into complex situation and becoming a challenge in coordinating several crisis management departments. In this regards, disaster prevention, preparedness and relief can be conceptualized into a design of hypothetical crisis game. Many complex tasks during development of emergency circumstance provide an opportunity for practitioners to train their skills, which are situation analysis, decision-making, and coordination procedures. While the training in physical workouts give crisis personal a hand-on experience in the given situation, it often requires a long time to prepare with a considerable budget. Alternatively, computational framework which allows simulation of crisis models tailoring into crisis scenario can become a cost-effective substitution to this study and training. Although, there are several existing computational toolsets to simulate crisis, there is no system providing a generic functionality to define crisis scenario, simulation model, agent development, and artificial intelligence problem planning in the single unified framework. In addition, a development of genetic framework can become too complex due to a multi-disciplinary knowledge required in each component. Besides, they have not fully incorporated a game technology toolset to fasten the system development process and provide a rich set of features and functionalities to these mentioned components. To develop such crisis simulation system, there are several technologies that must be studied to derive a requirement for software engineering approach in system’s specification designs. With a current modern game technology available in the market, it enables fast prototyping of the framework integrating with cutting-edge graphic render engine, asset management, networking, and scripting library. Therefore, a serious game application for education in crisis management can be fundamentally developed early. Still, many features must be developed exclusively for the novel simulation framework on top of the selected game engine. In this thesis, we classified for essential core components to design a software specification of a serious game framework that eased crisis scenario generation, terrain design, and agent simulation in UML formats. From these diagrams, the framework was prototyped to demonstrate our proposed concepts. From the beginning, the crisis models for different disasters had been analysed for their design and environment representation techniques, thus provided a choice of based simulation technique of a cellular automata in our framework. Importantly, a study for suitability in selection of a game engine product was conducted since the state of the art game engines often ease integration with upcoming technologies. Moreover, the literatures for a procedural generation of crisis scenario context were studied for it provided a structure to the crisis parameters. Next, real-time map visualization in dynamic of resource representation in the area was developed. Then the simulation systems for a large-scale emergency response was discussed for their choice of framework design with their examples of test-case study. An agent-based modelling tool was also not provided from the game engine technology so its design and decision-making procedure had been developed. In addition, a procedural content generation (PCG) was integrated for automated map generation process, and it allowed configuration of scenario control parameters over terrain design during run-time. Likewise, the artificial planning architecture (AI planning) to solve a sequence of suitable action toward a specific goal was considered to be useful to investigate an emergency plan. However, AI planning most often requires an offline computation with a specific planning language. So the comparison study to select a fast and reliable planner was conducted. Then an integration pipeline between the planner and agent was developed over web-service architecture to separate a large computation from the client while provided ease of AI planning configuration using an editor interface from the web application. Finally, the final framework called CGSA-SIM (Crisis Game for Scenario design and Agent modelling simulation) was evaluated for run-time performance and scalability analysis. It shown an acceptable performance framerate for a real-time application in the worst 15 frame-per-seconds (FPS) with maximum visual objects. The normal gameplay performed capped 60 FPS. At same time, the simulation scenario for a wildfire situation had been tested with an agent intervention which generated a simulation data for personal or case evaluation. As a result, we have developed the CGSA-SIM framework to address the implementation challenge of incorporating an emergency simulation system with a modern game technology. The framework aims to be a generic application providing main functionality of crisis simulation game for a visualization, crisis model development and simulation, real-time interaction, and agent-based modelling with AI planning pipeline.

Mergers and acquisitions (M&A) are today two common ways to expand and grow businesses. However, studies report that around 50-75% of all M&A transactions fail to yield expected results. This study focuses on the value creation realized in the post merger integration. During the post merger integration, organizational structures, IT systems and work routines need to change and integrate in order to achieve the desired synergies. Often when processes need to change or new ways of working are implemented, artifacts are utilized to facilitate the change. However, managers often fail to recognize the social perspective of organizational change. This study analyzes how a warehouse management system was used in a post merger integration to drive organizational change and establishing a common way of working between employees from different companies. The researchers have conducted a case study at a private equity firm that recently acquired and merged six companies in the fast moving consumer goods industry. As part of the case study, interviews and observations were made. This thesis presents two main results. First, that the choice to adopt a system-first-approach and neglecting human and task integration in the PMI resulted in several obstacles. The case company focused solely on system integration to realize the most obvious synergies of the different companies. This caused employee resistance and lack of trust and confidence towards managers and their intentions. It also yielded an ungiving and unhelping culture between employees that previously belonged to different companies. This indicates the importance of mixing employees from different companies after the merger. Moreover, the importance of creating cultural-unity under one brand is discussed. The results indicate that there should be a balance between human integration and task integration when merging several companies. Consequently, we present a two-by-two matrix that outlays the dependency of company characteristics on integration focus. Secondly, managers at the case company put too much faith and emphasis on artifacts and systems to change organizational behavior and neglected the perspective of sociomaterialism. This resulted in a failed implementation of the warehouse management system due to neglecting the employees’ perspective and ways of working. As a result, employees developed workarounds to the system and later abandoned the system. Consequently, managers should have adopted a technochange perspective when driving organizational change with IT systems. This means that the implementation of an IT system should be consider in conjunction with employees and their routines.
Fusioner och förvärv är två vanliga metoder som idag används av företag för att växa och ta nya marknadsandelar. Trots detta visar studier att 50-75% av alla förvärv misslyckas med att realisera förväntade synergier. Denna uppsats fokuserar på värdeskapandet som sker i integrationsfasen efter sammanslagningen. Under integrationsfasen integreras IT system, arbetsprocesser samt organisationsstrukturer för att realisera synergier. I samband med att företag ändrar på arbetsrutiner brukar artefakter användas för att stödja förändringsarbetet. Denna uppsats studerar hur företag kan använda sig av IT system under integrationsfasen för att driva förändring samt för att etablera ett gemensamt arbetssätt hos anställda med olika företagsbakgrunder. Denna uppsats är skriven tillsammans med ett riskkapitalbolag som tidigare köpt upp och slagit ihop sex företag inom industrin för snabbrörliga konsumentvaror. Som en del av fallstudien utfördes intervjuer och observationer på portföljbolaget. I denna uppsats presenteras två huvudresultat. Det första; bristen av fokus på integration av anställda från olika bolag ger upphov till motstånd och lågt förtroende till beslutsfattande. Det resulterade även i en fientlig och icke-hjälpande kultur mellan anställda med olika företagsbakgrunder. Resultaten påvisar vikten av att blanda anställda från olika företag i nya arbetssätt för att skapa tillhörighet och hjälpsamhet. Resultaten indikerar också att det är viktigt att ha ett gemensamt varumärke som alla anställda kan ställa sig bakom. Därför diskuteras balansen mellan integrering av anställda samt processer i en sammanslagning. I uppsatsen presenterar vi en två-gånger-två matris för att illustrera förhållandet mellan ett företags industriella karaktärsdrag samt integreringsfokus. Det andra huvudresultat visar att ledning samt styrelse hade för stort förtroende på artefakter för att förändra organisationellt beteende, det sociomaterilaistiska perspektivet följdes inte. Detta resulterade i en misslyckad implementering av ett IT system som ämnade att förändra beteendet hos anställda och realisera synergier. Anledningen hänvisas till försummelsen av de anställdas perspektiv samt arbetssätt. Detta resulterade i att de anställda utvecklade egna lösningar och i ett senare skede slutade använda systemet helt och hållet. Följaktligen borde företaget ha anammat ett “technochange” perspektiv för att driva förändring genom IT system inom företaget. Detta innebär att IT systemet måste ses som ett ekosystem tillsammans med anställda och arbetsprocesser, inte som ett självständigt system.

In this master thesis the risks and scenarios in the Swedish income-based pension system are investigated. To investigate the risks one has chosen to look at a vector autoregressive (VAR) model for three variables (AP-fund returns, average wage returns and inflation). Bootstrap is used to simulate the VAR model. When the simulated values are received they are put back in equations that describes real average wage return, real return from the AP-funds, average wage and income index. Lastly the pension balance is calculated with the simulated data. Scenarios are created by changing one variable at the time in the VAR model. Then it is investigated how different scenarios affect the indexation and pension balance. The result show a cross correlation structure between average wage return and inflation in the VAR model, but AP-fund returns can simply be modelled as an exogenous white noise random variable. In the scenario when average wage return is altered, one can see the largest changes in indexation and pension balance.
I det här examensarbetet (”Risker och scenarion i Sveriges inkomstgrundande allmänna pensionssystem) undersöks risker och scenarier i inkomstpensionssystemet. För att kunna undersöka riskerna har en vector autoregressive (VAR) modell valts för tre variabler (AP-fonds avkastning, medelinkomst avkastning och inflation). Bootstrap används för att simulera VAR modellen. När värden från simuleringarna erhållits kan dessa sättas in i ekvationer som beskriver real medelinkomst avkastning, real avkastning från AP-fonderna och inkomst index. Slutligen beräknas pensionsbehållning med simulerad data. Scenarierna utförs genom att en variabel i taget i VAR modellen störs. Sedan utreds hur denna störning påverkar resterande parametrar som beräknas. Detta görs för olika scenarion. I VAR modellen finns korrelationer mellan medelinkomst avkastning och inflation, men AP-fonds avkastning kan ses som vitt brus. De scenarier som har störst påverkan på indexeringen ¨ar då medelinkomst avkastningen ¨andras.

The monograph presents the research questions of efficiency of functioning of national standardization system of the Russian Federation, which was conducted by the authors in the framework of the analytical work on the order of Minpromtorg of Russia in 2018 (the state contract from April 17, 2018 No. 18401.16Д0190019.10.002) taking into account the actual directions of development of national standardization system of the Russian Federation and additional generalizations. The assessment of the current scenario of the development of the national standardization system of the Russian Federation was carried out using comparable indicators of the national standardization systems of France, Germany, great Britain and the USA. The findings and proposals were based on the results of a survey of civil servants at the Federal and regional levels on approaches to strategic dimensions of standardization. The methodology of forecasting the development of the national standardization system of the Russian Federation includes a scenario approach and a method of constructing dispersion diagrams (bubble diagrams) and sufficiently illustrates the current state of Affairs in the field of standardization at the national level. The developed tools will require additional configuration when changing the current development scenario from "inertial" to "progressive". A number of author's proposals to change the current scenario of development of the national standardization system of the Russian Federation are presented. It is of interest to a wide range of readers and specialists in the field of public administration, standardization and can be used in the preparation of curricula and manuals for undergraduate, graduate and further education.

AbstractThis chapter presents a qualitative description of the scenario storylines for the REFLEX project. The scenario descriptions provide the overall qualitative framework for the modeling activities by setting-up two holistic socio-technical scenarios based on different storylines: the moderate renewable scenario (Mod–RES) as reference scenario and the (de-)centralized high renewable scenarios (High–RES) as ambitious policy scenarios. The chapter highlights the definition of main techno-economic framework parameters, macro-economic and societal drivers as well as of the considered political environment.

Simulation may be the most practical way to assess the risk of systems with complex behaviors such as those that include hardware, software and human elements. However, since under normal design conditions human-designed systems generally perform in familiar and expected ways, a typical simulation will frequently lead to known and anticipated results. As such, the simulation program wastes a lot of time on familiar results without generating new knowledge about the system’s vulnerabilities. In order to increase our knowledge of risk, it would be preferable to push the system toward its limits to test the system’s ability to handle more difficult situations. Such an approach can help system designers to better understand risky situations and close the vulnerability gaps in their design. The primary objective of this study is to develop a risk simulation Planner (SimpraPlan) which generates scenarios that can explore the system’s vulnerabilities and offer a superior assessment of the risks involved. The Planner uses high level engineering knowledge (including the functional requirements and physical structure of the system) to generate scenarios that can exploit the system’s vulnerabilities. In this paper, the scenario generation process is explained in detail and scenarios generated by the SimpraPlan are compared with those generated by classical approaches to risk assessment.

Scenario based methods for testing and validation of automated driving systems in virtual test environments are gaining importance and becoming an important component for verification and validation processes of automated driving systems. The high system complexity of such systems and the high testing costs lead to an exponential increase of test efforts for real world testing. Recent research works have shown that it is necessary to drive and test billions of kilometers to ensure the safety and reliability of automated driving systems. This amount of test kilometers is far from possible and achievable for any test procedure regarding the time and costs. Using different methods and procedures it is possible to reduce the number of scenarios, which should be tested to approve the safety and reliability of automated driving systems. The scenario space consisting of critical and non-critical scenarios and the test effort can be reduced to an infinite and comprehensible amount of relevant scenarios for the system under test. Using scenario and simulation based approaches this effort can be efficiently reduced concerning the costs and time. The biggest challenges hereby are the detection and selection of a suitable scenarios and simulation environments or platforms for the system under test. Besides, suitable safety metrics are essential for the detection, evaluation, and reduction of relevant scenarios for testing of automated driving systems. Current scientific work offers various strategies and approaches for generating relevant scenarios for automated driving systems. All of them have their advantages and disadvantages related to the used virtual environment, vehicle model, traffic model, and the integration complexity. This paper presents a survey through different approaches, methods, and safety metrics for scenario generation and evaluation for testing and validation of automated driving systems. The reader should get a state of the art overview on scenario based approaches of automated driving systems.

A frontal impact scenario was simulated using a Finite Element Model of a Hybrid III 50th percentile male (LSTC, Livermore CA) along with seatbelt, steering system and driver airbags. The boundary conditions included acceleration pulse to the seat and the outputs including injury measures in terms of Head Injury Criterion (HIC), Normalized Neck Injury Criterion (NIJ) and Chest Severity Index (CSI) were extracted from the simulations. The kinematics of the Hybrid III were validated against the kinematics of post mortem human surrogates (PMHS) available in the literature. Using the validated setup, metamodels were generated by creating a design of varying different parameters and recording the responses for each design. First, the X and Z translation of dummy along the seat is provided as input for which there was no variation in the head injury criterion (HIC). Next, the input pulse to the seat is parameterized along with the seatbelt loading and the results are obtained respectively. The outputs, in terms of injury measures, are generated in the form of metamodels as a function of the parameters. The occupant model used for the frontal crash scenario in LS-Dyna is validated against the previously available crash experimental data. A total of 100 design points was generated with a varying combination of parameters. An increase in various injury measures was observed with an increase in the scale factor of the acceleration pulse. Also, it was found that chest severity index increased with an increase in the scale factor of the seat belt loading force.

A linked watershed model was evaluated on three watersheds within the U.S.: (1) House Creek Watershed, Fort Hood, TX; (2) Calleguas Creek Watershed, Ventura County, CA; and (3) Patuxent River Watershed, MD. The goal of this demonstration study was to show the utility of such a model in addressing water quality issues facing DoD installations across a variety of climate zones. In performing the demonstration study, evaluations of model output with regards to accuracy, predictability and meeting regulatory drivers were completed. Data availability, level of modeling expertise, and costs for model setup, validation, scenario analysis, and maintenance were evaluated in order to inform installation managers on the time and cost investment needed to use a linked watershed modeling system. Final conclusions were that the system evaluated in this study would be useful for answering a variety of questions posed by installation managers and could be useful in developing management scenarios to better control pollutant runoff from installations.

Topicality of modeling information transparency is determined by the influence it has on the effectiveness of management decisions made by an economic entity in the context of uncertainty and information asymmetry. It has been found that information transparency is a poorly structured category which acts as a qualitative characteristic of information and at certain levels forms an additional spectrum of properties of the information that has been adequately perceived or processed. As a result of structuring knowledge about the factor environment, a fuzzy cognitive model of information transparency was constructed in the form of a weighted digraph. Structural analysis and scenario forecasting of optimal alternatives of the fuzzy cognitive model made it possible to evaluate the classes of factors, identify their limited relations, establish the centrality of the roles of information transparency and information and communication security in the system built and evaluate their importance when modeling the situation self-development. Information visibility, reliability and availability have been found to have the strongest impact on the system. Taking into account different initial weights of the key factors — information transparency and information and communication security — the study substantiates the strategic ways for economic entities to achieve their goals in the context of uncertainty and information asymmetry, which allows us to use this approach as a tool for strategic management in the information environment.
