Measuring the efficiency of Serbian insurance companies

The transition period, and the still ongoing economic crisis, amplify the volatility in the domestic insurance market and forces the management of insurance companies to continuously monitor changes in the market, i.e. to identify risks and opportunities, and therefore to undertake certain activities. The focus of the business of insurance companies is based on satisfying the needs of existing and potential clients. Respecting the current situation in the insurance market in anticipation of future events, the management of insurance companies must create and implement the optimal strategy in line with the company’s capabilities. For this purpose it is necessary to measure the efficiency of the business, which is the subject of this paper where the Data Envelopment Analysis (DEA) method is applied to the case of insurance companies operating in Serbia

A VALUE PLATFORM ANALYSIS PERSPECTIVE ON CUSTOMER ACCESS INFORMATION TECHNOLOGY

Customer access information technologies (CAITs) provide a link between a firm and its customers. Firms invest in CAITs to reduce costs, increase revenues and market share, lock in existing customers and capture new ones. These benefits, however, are notoriously difficult to measure. This paper proposes an evaluative method for CAlT deployment called value platform analysis, that is based on a conceptual model drawn from the theory of retail outlet deployment in marketing science. The model focuses on the impact of CAIT features and environmental features on transactions generated by the CAIT. Specific econometric models are developed for deployment. Hypotheses regarding the likely impact of automated teller machine (ATM) location design choices and environmental features on ATM transactions are evaluated. The results indicate that there are a number of key features influencing ATM performance. Two distinct ATM deployment scenarios emerge: one for servicing a bank's own customers, and another for providing transaction services for customers for a fee.Information Systems Working Papers Serie

A Novel Approach for Sustainable Supplier Selection Using Differential Evolution: A Case on Pulp and Paper Industry

Abstract. Diverse sustainable supplier selection (SSS) methodologies have been suggested by the practitioners in earlier, to find a solution to the SSS prob-lem. A SSS problem fundamentally is a multi-criteria practice. It is a judgment of tactical significance to enterprises. The nature of this decision usually is dif-ficult and unstructured. Optimization practices might be useful tools for these types of decision-making difficulties. During last few years, Differential Evolu-tion has arisen as a dominating tool used for solving a variety of problems aris-ing in numerous fields. In the current study, we present an approach to find a solution to the SSS problem using Differential Evolution in pulp and paper in-dustry. Hence this paper presents a novel approach is to practice Differential Evolution to select the efficient sustainable suppliers providing the maximum fulfillment for the sustainable criteria determined. Finally, an illustrative exam-ple on pulp and paper industry validates the application of the present ap-proach

Software Complexity and Maintenance Costs

The effects of software complexity on the costs of Cobol maintenance projects within a large commercial bank are examined, and the impact of software complexity on the costs of software maintenance projects in a traditional information-system (IS) environment is estimated using a previously developed economic model of software maintenance. The model uses a multidimensional approach to measuring software complexity; other project factors that can be controlled by managers and that are believed to affect maintenance project costs are controlled for by the model. It is shown that software maintenance costs are affected significantly by software complexity in terms of module size, procedure size, and branching complexity. Dollar estimates are provided of the magnitude of the impact of software complexity on maintenance costs at a typical commercial site; the costs are high enough to justify complexity control and monitoring.Center for Information Systems ResearchCenter for the Management of Technology and Information in OrganizationsNational Science FoundationCenter for the Management of Technology and Information in OrganizationsInternational Financial Services Research CenterNational Science Foundation Grant No. SES-870904
