“…Although mainly focused on the management of decision making processes, there have been several approaches to specify requirements for decision support systems (DSS) in decision theory that provide universal requirements [15][16][17]. Their common denominator is the emphasis of an adaptive and flexible applicability of DSS.…”

Abstract:Technological advancement culminating in a globalized economy has brought tremendous improvements for mankind in manifold respects but comes at the cost of alienation from nature. Human activities nowadays are unsustainable and cause severe damage especially in terms of global depletion and destabilization of natural systems but also harm its own social resources. In this paper, a sustainability assessment method is developed based on a bio-inspired sustainability framework that has been developed in the project TRR 141-C01 "The biomimetic promise". It is aims at regaining the advantages of societal embeddedness in its environment through biological inspiration. The method is developed using a structured approach including requirement specification, description of the inventory models on bio-inspiration and sustainability assessment, creation of a bio-inspired sustainability assessment model and its validation. It is defined as an accompanying assessment for decision support, using a six-fold two-dimensional structure of social, economic and environmental functions and burdens. The method is applied and validated in 6 projects of TRR 141 and its applicability is exemplarily shown by the assessment of "Bio-flexi", a biobased and biodegradable natural fiber reinforced plastic composite for indoor cladding applications. Based on the findings of the application the assessment method itself is proposed to be advanced towards an adaptive structure and a consequent outlook is provided.

“…Rational decision making implies that the decision maker operates under certainty, knows the alternatives as well as the related outcomes, is conversant with the decision criteria and has the ability to make an optimum choice and implement it (Towler, 2010;Simon, 1997Simon, , 2009. In reality, this is not the case among actors operating in uncertain and complex business environments (Keen & Sol, 2008), such as the agricultural domain (Aregu, 2014;Parker, 2001).…”

Because of agriculture's direct link to global food security, it is strategically important. This research recognizes the importance of a paradigm shift from subsistence to commercial agriculture for East Africa to advance this strategic importance. This shift has particularly had significant impact on the poultry industry. In East Africa, commercial poultry farming has steadily taken root over the last decade albeit the challenge of inadequate farm management competences among farmers which has been aggravated by lack of systems and approaches to enhance effective and efficient decision making among poultry farmers in the region. The focus of this study therefore is how decision processes of poultry farmers can be enhanced so that they are able to efficiently monitor and manage their operations as they seek to take advantage of the trend of commercialisation of the poultry industry. This paper explores the decision making practices of poultry farmers with an aim of enhancing these decisions for improved productivity of poultry farms in the region. The key research question this study seeks to address is: How can decision making among poultry farmers in East Africa be enhanced?

“…It is important that designers of cognitive support systems ensure that the support they provide helps answer the “right” questions with respect to user requirements in the domain (Parker, 2001). Scenarios are one useful method for helping to negotiate and identify the concrete uses of a given decision model, and for showing how technology can be integrated in the task domain to the best effect.…”

. The work has so far been focused on the military domain, but the model and the software tools developed to implement it are generalizable to a range of commercial and publicsector settings including industrial parks, corporate campuses, and civic facilities. The approach suggests that anti-terrorism decision makers determine mitigation project allocations using measures of facility priority and mitigation project utility as inputs to the allocation algorithm. The three-part hybrid resource allocation model presented here uses multi-criteria decisionmaking techniques to assess facility (e.g., building, hangar) priorities, a utility function to calculate antiterrorism project mitigation values (e.g., protective glazing, wall coatings, and stand-off barriers) and optimization techniques to determine resource allocations across multiple, competing AT mitigation projects. The model has been realized in a cognitive support system developed as a set of loosely coupled Web services. The approach, model, and cognitive support system have been evaluated using the cognitive walkthrough method with prospective system users in the field. In this paper we describe the domain, the problem space, the decision model, the cognitive support system and summary results of early model and system evaluations. IntroductionThe recent history of terrorist attacks on both military and civilian targets at home and abroad suggests a need for increased emphasis on effective implementation of mitigations to protect industrial facilities. The effects of attacks such as the 1996 truck bombing of the Khobar Towers housing complex, the 1998 U.S. embassy bombings in Kenya and Tanzania, and recent attacks on expatriate housing complexes in Saudi Arabia may have been diminished had more effective facility anti-terrorism mitigations been installed. Anti-terrorist mitigations are generally expensive, however, and deciding what, how, where, and when to allocate resources to protect critical infrastructure is a difficult problem. We have been working on a methodology, decision model, and cognitive support system to aid with more effective allocation of anti-terrorism (AT) resources at Marine Corps installations. Though our work has so far focused on the military domain, the methodology, decision model, and supporting tools are generalizable to a range of commercial and public-sector settings including industrial parks, corporate campuses, and civic facilities.Anti-terrorism facility mitigations are designed to protect people and property from asymmetric attack by nontraditional hostile organizations. Anti-terrorism mitigations include measures such as blast-resistant glazing (windows are the major cause of injury and death in most bomb attacks), wall-hardening coatings, fences, vehicle stand-off barriers, enhanced lighting, video surveillance, and guards. Allocating available funds across different anti-terrorism mitigation projects, with the exception of guards, is a project selection and capital budgeting problem. Though a range of welldeveloped tech...
