...then response to the changing market condition and customer needs. A more defined organizational structure, performance metrics and decision support systems (DSS) in SCM is required to create competitive advantages for an organization. Since Information Technology/Information System (IT/IS) is an integral component of SCM, DSS is inevitable in making available the right information at the right time so that managers can make timely and more accurate decisions. However, there is no best known DSS type that is required to effectively manage a supply chain. A properly designed DSS will help decision makers to extract useful information from raw data, documents, personal knowledge and/or business models with the objective of identifying and solving problems, and making decisions. Decision Support Systems (DSS) are a specific class of computerized information system that supports business and organizational decision-making activities. The DSS in supply chain management can be a model, communication, data, document and knowledge driven. Three fundamental components of DSS architecture are: (i) Input data: database or knowledge base, (ii) Analytical Tool: the model (decision context and user criteria) and (iii) use interface, should be given due consideration while developing supply chain decision support systems (Figure1: DSS Components).

Calls for service are received at the PSAP and then dispatched via radio and computer terminal to law enforcement officers assigned to respond. Leading up to the use of Information Systems such as computer aided dispatch (CAD) the PSAP relied on radio’s to communicate information to the law enforcement officers. With the development of CAD and Record Management Systems (RMS) the sheriff’s office recognized the value of these systems and in 2007 adopted IMC CAD+RMS (Information Management Corporation CAD+RMS, 2007). IMC is a multifaceted information dissemination system utilized by dispatchers in the PSAP, emergency responders and their records management departments. IMC utilizes a closed stand-alone network and was developed for emergency management services such as fire, rescue and law enforcement departments.
