Title: RESOURCE SHARING SIMULATION SYSTEM (RSSS): A DECISION SUPPORT SYSTEM FOR LIBRARY RESOURCE SHARING NETWORKS. A CASE STUDY

Abstract: This study explores the feasibility of the Resource Sharing Simulation System (RSSS) as a decision support system. This RSSS was developed at the School of Library and Information Science, University of Pittsburgh, for library resource sharing networks. The system has been designed specifically to address the questions pertaining to economics of information transfer, especially to derive break-even points based on the values relative to the major relevant local vs network parameters.

Problems in library networking environment do not yield to algorithmic solutions because of the large number of interrelated variables involved. They are best approached heuristically--an ad-hoc mode of problem solving. Heuristics reflect 'bounded rationality,' a result of cognitive limitations of decision makers in the resolution of complex problems. A decision support system using simulation techniques may improve the heuristics.

The resource sharing simulation system uses modeling and computer simulation techniques that facilitate experimentation so that more or less random searches guided by a few heuristics become feasible. The system has been designed to reflect and mimic the conceptual model of the resource sharing network developed for that purpose. The simulation model basically consists of a set of data structures that represent the structures of the conceptual model which consists of modules that manipulate by computer the data structures to represent the behavior of the conceptual model.

This study focused on exploring how this system could be used to evaluate economically viable alternatives to existing systems in small libraries, and to probe into the question of cost reduction in cataloging operations. The methodology for data collection was based on the conceptual framework of the system. In order to execute the simulation questions being addressed were presented in the form of models capable of being processed by the computer. The results of simulation demonstrated that the system supports decision making processes. The system with its edit, modeling and computational capabilities extends cognitive abilities and can be used successfully for long and short range financial planning on an iterative basis.
