Integration of a mathematical model within reference task model at the procurement process using BPMN for disasters events

Abstract

The presented approach on this article is related to the task streams activities according to the reference model from humanitarian logistics tasks proposed by Blecken (2009) using the Business Process Modeling Notation (BPMN). Steps were presented initially for the mathematical model insertion, emphasizing on the function of supplies acquisition during the phase of response in case of disasters. The outcome from this model consists on determining which suppliers have the capability to deliver emergency supply items on the requested date. Illustrating the usage of this model, we will show the development of a small example. The first approach contributions is the BPMN specification for assessment tasks and procurement, according to the reference model, including new tasks. The second contribution is represented by a mathematical model insertion, specifically on the task “select supplier”, from the reference model. Therefore, there was a graph model proposed for the Network Flow Model, which was adapted to the Humanitarian Logistics context.
