Performance evaluation for ERPS in terms of individual performance

摘要

An Enterprise Resource Planning System (ERPS) is a complex network composed of various business processes. This network can be called an ERP net. This article proposes an analytic method to evaluate the performance of such net in terms of individual performance. To facility such evaluation, the nodes in the net denote the persons responsible for the business operations in the processes. The links between nodes denote the process precedence relationships. When the process starts, the documents are initiated from the source node to its succeeding nodes. Finally, the documents are released in the destination node. Thus, the performance of an ERPS is related to the document flow under the net. The performance failure of an ERPS is therefore described as in the condition that the document flow of the system is under the acceptable level, d. By collecting the data of individual performance, we propose a performance index, the probability of maximum flow not less than d, to evaluate the performance of an ERPS. Some numerical examples are illustrated for this approach.
