The objective of this paper is to compare the previous models to find the advantages and disadvantages of them for the future development of a decision model for IT supplier selection

Guidelines for Software Development for Decision Support Systems

One of the activities of the System and Decision Sciences Program is the collaboration with scientists and institutes from different countries and with other programs and projects at IIASA in the field of Methodology of Decision Analysis. The main results of these activities are the development of theory, methodology and software for Decision Support Systems. A considerable amount of experience and software has been accumulated for over ten years of this type of cooperation. However, the analysis of the results of software development activities indicates the need for setting and observing some specified Guidelines for Software Development. This Working Paper contains a first version of such Guidelines which is the result of discussions with software developers. The draft of this Working Paper has been distributed for comments to about hundred scientists involved in development of software for Decision Support Systems. Since no reservations for the proposed Guidelines have been communicated to the author, one can assume that there is a general agreement for setting these Guidelines as a working scheme for the development of software for Decision Support Systems within the cooperation with the System and Decision Sciences Program. Although the Guidelines are oriented for a specific type of software, most of them can and should be observed in the development of any kind of software

The mathematical approach for proximity analysis for 3D GIS

Next generation of GIS software would highly depend on 3D analysis in solving geographic problems. 3D analysis is a very important component for GIS as it defines as decision making tools for geographic features. One would like to query about geographic object from numerical calculation or propose optimum solutions for GIS applications. Such desired components in future software or system are to deal with the 3D analytical solutions. This paper presents a portion of the problems, which are 3D solid buffering for 3D GIS. This analytical solution is very important for 3D spatial analysis. The discussion related to the implementation of buffering model for solid object is the main concern in the research, where the primitive objects of point, line, and face will be taken in consideration for the development of 3D solid bufferin

Mapping implemented strategies of bringing Internet-based software applications to market using storytelling research methods

University of Technology Sydney. Faculty of Business.The research offers an advanced hermeneutic framework for the study of B2B decision-making processes for software application development. The proposal builds dynamic sensemaking elements onto existing hermeneutic analysis frameworks used in marketing research (Arnold & Fisher 1994; Thompson Pollio & Locander 1994; Thompson 1997). The “hermeneutic circle” is extended to a multilevel “hermeneutic system” starting with written accounts of the decision-making associated with the development and delivery of new software applications – these accounts are then revisited (Langley et al. 1995) through multiple rounds of etic and emic interpretation. An extended form of marketing Decision Systems Analysis (DSA) that complements the advanced hermeneutic analysis framework is also proposed and applied, building on existing B2B Marketing DSA (Hulbert, Farley & Howard 1972; Woodside & Samuel 1981; Woodside 1994; Woodside & Voss 1999) with extended DSA Models, events chronology maps, and cognitive maps. The proposed framework and supporting analysis are applied to six application software houses that created new Internet-based software applications which were either disruptive (Christensen 2003) or supporting disruptive software applications. Findings from six case studies suggest that the hermeneutic research framework proposals provide a strong systematic platform for analysing and interpreting decision-making with deep prospective, introspective, retrospective, and with imaginatively unbounded current and future perspectives. Individual case-study and cross-case findings were incorporated into a set of new and revised theory propositions for software application developer Structuration at individual, firm (including multi-firm) and industry levels. The propositions provide a base of knowledge for the further development of a cognitive view of a software application development firm

The Development and Validation of a Generic Instrument, QoDoS, for Assessing the Quality of Decision Making.

Introduction: The impact of decision-making during the development and the regulatory review of medicines greatly influences the delivery of new medicinal products. Currently, there is no generic instrument that can be used to assess the quality of decision-making. This study describes the development of the Quality of Decision-Making Orientation Scheme QoDoS© instrument for appraising the quality of decision-making. Methods: Semi-structured interviews about decision-making were carried out with 29 senior decision makers from the pharmaceutical industry (10), regulatory authorities (9) and contract research organizations (10). The interviews offered a qualified understanding of the subjective decision-making approach, influences, behaviors and other factors that impact such processes for individuals and organizations involved in the delivery of new medicines. Thematic analysis of the transcribed interviews was carried out using NVivo8® software. Content validity was carried out using qualitative and quantitative data by an expert panel, which led to the developmental version of the QoDoS. Further psychometric evaluations were performed, including factor analysis, item reduction, reliability testing and construct validation. Results: The thematic analysis of the interviews yielded a 94-item initial version of the QoDoS© with a 5-point Likert scale. The instrument was tested for content validity using a panel of experts for language clarity, completeness, relevance and scaling, resulting in a favorable agreement by panel members with an intra-class correlation coefficient value of 0.89 (95% confidence interval = 0.56, 0.99). A 76-item QoDoS© (version 2) emerged from content validation. Factor analysis produced a 47-item measure with four domains. The 47-item QoDoS© (version 3) showed high internal consistency (n=120, Cronbach’s alpha = 0.89), high reproducibility (n=20, intra-class correlation =0.77) and a mean completion time of 10 min. Reliability testing and construct validation was successfully performed.Peer reviewedFinal Published versio

From zero to hero: A process mining tutorial

Process mining is an emerging area that synergically combines model-based and data-oriented analysis techniques to obtain useful insights on how business processes are executed within an organization. This tutorial aims at providing an introduction to the key analysis techniques in process mining that allow decision makers to discover process models from data, compare expected and actual behaviors, and enrich models with key information about the actual process executions. In addition, the tutorial will present concrete tools and will provide practical skills for applying process mining in a variety of application domains, including the one of software development

A decision support system for corporations cyber security risk management

This thesis presents a decision aiding system named C3-SEC (Contex-aware Corporative Cyber Security), developed in the context of a master program at Polytechnic Institute of Leiria, Portugal. The research dimension and the corresponding software development process that followed are presented and validated with an application scenario and case study performed at Universidad de las Fuerzas Armadas ESPE – Ecuador. C3-SEC is a decision aiding software intended to support cyber risks and cyber threats analysis of a corporative information and communications technological infrastructure. The resulting software product will help corporations Chief Information Security Officers (CISO) on cyber security risk analysis, decision-making and prevention measures for the infrastructure and information assets protection. The work is initially focused on the evaluation of the most popular and relevant tools available for risk assessment and decision making in the cyber security domain. Their properties, metrics and strategies are studied and their support for cyber security risk analysis, decision-making and prevention is assessed for the protection of organization's information assets. A contribution for cyber security experts decision support is then proposed by the means of reuse and integration of existing tools and C3-SEC software. C3-SEC extends existing tools features from the data collection and data analysis (perception) level to a full context-ware reference model. The software developed makes use of semantic level, ontology-based knowledge representation and inference supported by widely adopted standards, as well as cyber security standards (CVE, CPE, CVSS, etc.) and cyber security information data sources made available by international authorities, to share and exchange information in this domain. C3-SEC development follows a context-aware systems reference model addressing the perception, comprehension, projection and decision/action layers to create corporative scale cyber security situation awareness

Applications of Formal Methods to Specification and Safety of Avionics Software

This report treats several topics in applications of formal methods to avionics software development. Most of these topics concern decision tables, an orderly, easy-to-understand format for formally specifying complex choices among alternative courses of action. The topics relating to decision tables include: generalizations fo decision tables that are more concise and support the use of decision tables in a refinement-based formal software development process; a formalism for systems of decision tables with behaviors; an exposition of Parnas tables for users of decision tables; and test coverage criteria and decision tables. We outline features of a revised version of ORA's decision table tool, Tablewise, which will support many of the new ideas described in this report. We also survey formal safety analysis of specifications and software

Domain specific software design for decision aiding

McDonnell Aircraft Company (MCAIR) is involved in many large multi-discipline design and development efforts of tactical aircraft. These involve a number of design disciplines that must be coordinated to produce an integrated design and a successful product. Our interpretation of a domain specific software design (DSSD) is that of a representation or framework that is specialized to support a limited problem domain. A DSSD is an abstract software design that is shaped by the problem characteristics. This parallels the theme of object-oriented analysis and design of letting the problem model directly drive the design. The DSSD concept extends the notion of software reusability to include representations or frameworks. It supports the entire software life cycle and specifically leads to improved prototyping capability, supports system integration, and promotes reuse of software designs and supporting frameworks. The example presented in this paper is the task network architecture or design which was developed for the MCAIR Pilot's Associate program. The task network concept supported both module development and system integration within the domain of operator decision aiding. It is presented as an instance where a software design exhibited many of the attributes associated with DSSD concept
