The right decision via system modelling

Are you planning to produce your products sustainably or would you like competent environmental advice? Every decision you make as an entrepreneur has far-reaching effects – including on the environment. Consult us as experts and make the right decisions with our system modelling!

Nature and our economy have one thing in common: they are complex, dynamic systems in which undesirable and unforeseen side effects can sometimes occur after a decision has been made. We see ourselves as specialists in the core areas of environmental consulting and pollutants and can thus help you to create a solid basis for making decisions, on the basis of which you can make future decisions within the framework of your company with more specialist knowledge. With the help of our system modelling we show you different variants with all their consequences. We present connections and show how a single factor can change the entire system. For example, fuels from biomass conserve fossil raw materials, but can also pollute the soil and groundwater. With our many years of experience, we are able to model all the consequences for you before you make a far-reaching decision.

Better results with Fuzzy Logic

The imprecise is difficult to understand. For example, there may be a great deal of expert knowledge about a subject on which there is no quantitative data. The Fuzzy Logic method that we use helps to describe qualitative knowledge mathematically precisely and to offset it against measurement data. In this way, even inaccurate data can be recorded precisely. This makes it possible to use expert knowledge in a transparent and comprehensible way – for system modelling and forecasts, for example. Fuzzy Logic therefore helps to achieve better results – with less effort. See for yourself and learn more about our projects that we have already successfully completed using this method.

Material flow analysis as the basis of every life cycle assessment

If you depend on your company to consider specific material and energy flows, then the so-called material flow analysis is the right method for you. This method enables us to record and present technical, economic or ecological systems. An important competence, for example, to determine the climate-relevant emissions of a region and to use resources efficiently. The material flow analysis shows which substances enter a cycle where and for how long – the basis of any life cycle assessment. With the help of this analysis, we can provide you with a basis for planning and show you how a system can be improved. Contact us if you would like to make use of one of our services – we look forward to hearing from you and will be happy to assist you with our many years of experience!

Material flow ­ana­ly­sis is used when specific material and energy flows should be taken into consideration.

Every company and or­ga­ni­sa­ti­on has an interest in using resources efficiently. Excessive waste is not only an impact on the environment, but can involve not indifferent disposal costs. The determination of climate related emissions (such as VOCs) of a region also demands knowledge of the material flow and economic factors. We have this knowledge. (more…)

The Fuz­zy Lo­gic Method is the right choice when sufficient expert knowledge is on hand, but no quantitative data.

Experts often differ in their conclusions, which can lead to difficulties at the time of making decisions. Often the reasoning behind the expert advice is not easy to translate into practical action, and at times it can be difficult to marry qualitative expert conclusions with empirical test data.

Fuz­zy Lo­gic is a method which can describe qualitative knowledge with mathematical precision, while integrating measured data. This then makes it possible to utilise expert knowledge in a transparent and comprehensible way, such as for the purposes of system modelling and prognoses. The experience gained through various air quality and biodiversity projects has shown that Fuz­zy Lo­gic helps to obtain better results at contained cost.

With hindsight everyone knows better. But some decisions do have to be made in the absence of a full set of reliable data. Therefore, in order to create the basis for solid decision-making it is necessary to clarify where the opportunities and risks lie. The Mon­te-Car­lo Me­tho­d comes into play here.

It allows a system to be modelled using assumptions and estimates about how variable the results of a decision may be. This allows the risks inherent in a project or system to be quantified realistically. The Mon­te-Car­lo Me­tho­d is suitable for sensitivity analyses and the calculation of confidence limits. It is also used, for example, in the Life Cycle Assessment, to calculate the significance of the results.

As required, we work with our clients to produce a model of the system in question, with all relevant assumptions and corresponding uncertainties. We calculate from this the variability of the results, or limit ourselves to the calculation of the variability of the results of the client supplied model.
