Effective applications of microcomputer-based management information and decision support systems for small and medium sized enterprises
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Firstly, this thesis reviews the literature on the application of microcomputer-based Management Information Systems (MISs) and Decision Support Systems (DSS) to Small and Medium sized Enterprises (SMEs). It is found that the hardware platform today is already sufficient for SMEs. However, information regarding successful implementation of MISs for SMEs is scarce and largely fragmented.
DSS requires more focused and dedicated use of information to support managerial decision making. Unfortunately, the development of DSSs for SMEs is even more backward. Yet, there is an emerging need for SMEs today because business operations have become more sophisticated under intensified
competition.
With this scenario in mind, the author undertook intensive questionnaire and case surveys to find out the current development and trends for the effective applications of MISs and DSSs. In 1987, the author was awarded the Oshikawa Fellowship by Asian Productivity Organisation in Tokyo and started the present research. 446 completed questionnaire survey sheets from U.K. and Hang Kong have been received and analysed. 67 SMEs and related organisations in 6 developing/developed countries were also visited. This forms the knowledge for the development of expert systems (ES) for effective applications of MIS.
The approach for DSS is based on a carefully selected business game which has most of the common business decision parameters. Intensive experiment with over 100 subjects was conducted in running the game, with an average time contribution of about 20 hours/person. The findings are again consolidated and structured into an ES.
Longitudinal research was conducted in 5 representative SMEs. With the use of action learning and participation of the researcher, more in-depth firsthand information were obtained and analysed. These form part of the input to the ES as well.
Both ES have been validated and further improved. The experimenters find these as keys to develop MIS/DSS for SMEs. A marketing plan is suggested to launch these two products so that they can become more easily available. Finally, recommendations are made on the effective use of the ES and for further development
Intelligent Decisional Assistant that Facilitate the Choice of a Proper Computer System Applied in Busines
No full textThe choice of a proper computer system is not an easy task for a decider. One reason could be the present market development of computer systems applied in business. The big number of the Romanian market players determines a big number of computerized products, with a multitude of various properties. Our proposal tries to optimize and facilitate this decisional process within an e-shop where are sold IT packets applied in business, building an online decisional assistant, a special component conceived to facilitate the decision making needed for the selection of the pertinent IT package that fits the requirements of one certain business, described by the decider. The user interacts with the system as an online buyer that visit an e-shop where are sold IT package applied in economy.database, knowledge-base, decision tree, DSS, data mining, agents, reasoning, collaborative
Návrh retail business DSS
No full textThe reason why I chose this topic is not nor the complexity of global world neither the growing pressure on quick and effective managerial resolutions as it is mentioned in similar scripts. Surprisingly, the main impulse was the synergy of three principal aspects of my master study. First millstone was a study of main specialization by its self: Information management, on cathedra of System analysis, faculty of Informatics and Statistics, Economic University in Prague. The second angle is the minor specialization of the study: Retail business, on cathedra of Commercial business, faculty of International relations, Economic University in Prague. Last but no least aspect is simultaneously exercised practice in field of managing the project ICT/ IS and logistic operations. Prime aim of this work is a concept of presentation of DSS, which is intended to support the decision-making process of development of a retail chain of fictitious firm JK, a.s. Partial goals heading to fulfilment of a prime aim are: determination of a theoretical expectations, methods and methodic needed to proposal of DSS, description, and analysis of company and retail chain, procedural analyze of decision making-process of retail chain development, concept of system dynamic model, which forms the root of DSS and the concept of DSS by its self. Secondary aim is to gather satisfactory amount of theoretical and practical details for presentation of project DSS to management of the company. The biggest benefits of this work are fulfilment of a prime and secondary aim, together with the project DSS it self, which could be partly applied for the support of the decision-making process in the company. Further assets for the firm JK, a.s. are conclusions of some captures, which could be used for planning of marketing campaigns, generating Business Knowledge Base, evaluation of affectivity of sales and human resources, etc. The final bonus for the author of this work is the personal progression, profession growth, caused by gain of ne
Development of DSS for Long-term Planning - Reviewing Existing Tools
No full textThis report provides a review of existing decision support system (DSS) tools in the field of long-term flood risk management as a basis for the development of a new tool covering outcomes of the integrated methodology of FLOODsite. A DSS is a computer-based approach or methodology supporting individual or collective decision makers in the solution of semi-structured problems. It uses a database and, models with an user interface and provides results in a readily assimilated way. The overall aim of this report is to identify the advantages and disadvantages of existing tools as well as the derivation of concrete demands for the future developments. The nineteen tools considered were predominately developed in Germany, The Netherlands and United Kingdom as well as some other European countries.Floodsit
SHIP-deficient, alternatively activated macrophages protect mice during DSS-induced colitis
No full textmφ are heterogeneous in their functions, and although it is clear that inflammatory mφ contribute to inflammation in IBDs, multiple lines of evidence suggest that M2a mφ may offer protection during intestinal inflammation. In vivo SHIP‐deficient mouse mφ are M2a so SHIP‐deficient mice provide a unique genetic model of M2a mφ. Based on this, this study tested the hypothesis that SHIP‐deficient, M2a mφ protect mice from intestinal inflammation. The objectives were to compare the susceptibility of SHIP+/+ and SHIP−/− littermates with DSS‐induced intestinal inflammation and to determine whether protection was mφ‐mediated and whether protection could be transferred to a susceptible host. We have found that SHIP−/− mice are protected during DSS‐induced intestinal inflammation. SHIP−/− mice have delayed rectal bleeding and reduced weight loss, disruption of intestinal architecture, and immune cell infiltration during DSS‐induced colitis relative to their WT littermates. Using liposome depletion of mφ, we found that SHIP−/− mouse protection was indeed mφ‐mediated. Finally, we determined that SHIP−/− mφ‐mediated protection could be conferred to susceptible WT mice by adoptive transfer of M2a mφ derived ex vivo. This study supports our hypothesis by demonstrating that SHIP‐deficient, M2a mφ are protective in this murine model of acute intestinal inflammation. Adoptive transfer of M2a mφ to patients with IBDs offers a promising, new strategy for treatment that may be particularly useful in patients who are otherwise refractory to conventional therapies.Peer reviewedfinal article publishedinflammatory bowel diseaseintestinal inflammationmφphenotyp
Configurable DSS for Uncertainty Management by Fuzzy Sets
No full textAbstractIn this paper, we propose a Configurable Model Based DSS capable of dealing with generic problems being modeled by Linear Programming (LP) and by Fuzzy Sets (FS) in a deterministic and uncertain context, respectively. The DSS assumes the transformation of the original model with fuzzy coefficients into an equivalent crisp model where the fuzzy coefficients are represented as alpha-parametric values, which can vary in a predefined interval based on the alpha parameter. Through the DSS, solutions obtained by solving the deterministic model and the equivalent crisp model for different alpha-values are compared based on the objectives and performance parameters defined by the Decision Maker (DM). Due to the uncertainty in data, expected performance of solutions can change under real situations. The DSS allows simulating future real situations by generating different projections of uncertain parameters. New performance of previously generated solutions can be tested under these hypothetical real situations by means a third model (Model for the Real Performance Assessment). Finally, the DM can choose the solution to be implemented taking into account the performance of solutions under planned and real uncertainty

Het succes van DSS: Leerervaringen van ontwikkeling van Decision Support Systems in dynamische multiactor context
No full textIedereen neemt elke dag beslissingen variërend van hoe naar het werk te gaan tot wat eten met de lunch. Ondanks dat voor een deel het nemen van beslissingen ook een kwestie van geluk is, is het belangrijk om bij het nemen van goede beslissingen gebruik te maken van beschikbare en relevante informatie waar we onze keuzes op kunnen baseren. Daarbij kunnen bij complexe beslissingen Decision Support Systems van nut zijn. Er bestaat geen eenduidige definitie van wat een DSS is (Kwakkel, 2006). Terugkerende elementen in de definitie van DSS zijn computergebaseerde systemen die het nemen van beslissingen ondersteunen (Kwakkel, 2006). Er is zelfs onderzoek gedaan naar het grote aantal bestaande definities van Decision Support Systems door Sol (1985) die concludeerde dat de focus meer naar het definiëren van ontwerpomgevingen zou moeten verschuiven. In dit onderzoek wordt de volgende definitie gebruikt: Decision support systems (DSS) zijn systemen, veelal op een computer werkend, die informatie van vaak verschillende bronnen bij elkaar brengen om een gebruiker te ondersteunen in het organiseren, analyseren en evalueren van informatie om te komen tot een beter onderbouwde beslissing (Sauter, 1997)
