Model-based scenario analysis with the ASM1 model was used to evaluate the effect of different process modifications on the biological nitrogen removal process for a specific case study (municipal wastewater treatment plant). Simulations showed that the construction of extra tank volume was needed to obtain the effluent standard of 15 mg N/l. However, the renovation scenarios resulting from a m...

Designing consumer products has grown more challenging due to the increasingly complex characteristics of these products. Design research has promoted the use of scenarios –concrete stories about product useto support the design process. However, design practice still lacks a thorough guidance that integrates various scenario uses effectively. In this paper, we describe a software concept that ...

Salmonellosis in people is a costly disease, much of it occurring because of food associated exposure. We develop a farm-to-fork model which estimates the pork associated Salmonella risk and human health costs. This analysis focuses on the components of the pork production chain up to the point of producing a chilled pork carcass. Sensitivity and scenario analysis show that changes that occur i...

a r t i c l e i n f o The Combined Simulation Approach (CSA) is a way to evaluate risks and address potential unforeseen problems in a more interactive way than what is often observed in practice in companies or sectors. The approach is based on a combination of scenario analysis and discrete-event computer simulation with which the strategies can be continuously developed. The contribution of ...

Scenarios have proven useful to elicit, validate and document requirements but cannot be used in isolation. Our concern in this paper is to integrate scenario-based techniques in existing methods. We propose a set of operators to support such an integration. This set is classified in two sub-sets: the one dealing with the integration of the product models of the two initial methods and the one ...

Scenario analysis is a qualitative tool for policy analysis and business planning support that enables stakeholders and policymakers to consider decisions with enhanced awareness, due its cognitive implications for planned behavior. In this study, the role of scenario analysis is discussed in the context of the future development of the market of organic food products in Europe. The strengths a...

Agency theory has long been a stalwart of IS research and is one of the most commonly used lenses to study the relationship between a principal and an agent. The Theory of Relationship Constraints (TRC) has recently been recommended as an informationoriented alternative to agency theory. TRC suggests that three attributes (i.e., the level of information asymmetry, levels of tacit and explicit k...

The success of Ambient Intelligence (AmI) will depend on how secure it can be made, how privacy and other rights of individuals can be protected and how individuals can come to trust the intelligent world that surrounds them and through which they move. This article addresses these issues by analysing scenarios for ambient intelligence applications that have been developed over the last few yea...
