Disaster Warning System in the Philippines Through Enterprise Engineering Perspective: A Study on the 2013 Super Typhoon Haiyan

In this research on disaster warning systems, the Philippines was selected to be a case study. The Philippines was hit by a particularly bad storm in 2013 Super Typhoon Haiyan. Here we focused on warning system process management from an enterprise engineering perspective. In understanding warning systems, it is necessary to know the essence of overall processes. The objective of this qualitative study is to determine the system’s essential components by using the Design and Engineering Methodology for Organizations (DEMO). This involves both assigning responsibility levels and utilizing both traditional means such as broadcast vehicles with speakers and radios and newer means such as Internet channels to disseminate warning information. The findings provide a simple model explaining the disaster-related organization and communication structure. They also contribute a practical aspect in the form of suggestions to planners and decision makers that may assist them in preparing mitigation plans for projected natural disasters.

Using the DEMO methodology for modeling open source software development processes

Context Open source software development (OSSD) process modeling has received increasing interest in recent years. These efforts aim to identify common elements in the development process between multiple open source software (OSS) projects. However, the complexity inherent to OSSD process modeling puts significant demands on the modeling language. Objective In this paper, we propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. Method We investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. DEMO models were constructed to describe the NetBeans Requirements and Release process. In addition, the quality of these DEMO models was evaluated using a quality framework for conceptual modeling. Results Our results showed that our DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. In addition, the evaluation of the models developed in this paper by using the quality framework for conceptual modeling showed that the models were of high quality. Conclusions We have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models. However, given some potential drawbacks with respect to understandability and implementability, we primarily propose the use of DEMO within OSSD process modeling as an analysis tool that should be complemented with other techniques and models for communication and reenactment purposes.
