This paper develops tests and validates a model for the antecedents of open source software (OSS) defects, using Data and Text Mining. The public archives of OSS projects are used to access historical data on over 5,000 active and mature OSS projects. Using domain knowledge and exploratory analysis, a wide range of variables is identified from the process, product, resource, and end-user characteristics of a project to ensure that the model is robust and considers all aspects of the system. Multiple Data Mining techniques are used to refine the model and data is enriched by the use of Text Mining for knowledge discovery from qualitative information. The study demonstrates the suitability of Data Mining and Text Mining for model building. Results indicate that project type, enduser activity, process quality, team size and project popularity have a significant impact on the defect density of operational OSS projects. Since many organizations, both for profit and not for profit, are beginning to use Open Source Software as an economic alternative to commercial software, these results can be used in the process of deciding what software can be reasonably maintained by an organization.

“…Examples of possible interventions include legal remedies that revoke business licenses or mandate employee training; resource reallocation to reroute traffic patterns; human relations job and social services messaging. We know licit networks enhance their resilience using slack resources (e.g., more reserve inventory), responsive processes (e.g., nearshoring), and increased visibility through information sharing (e.g., track and trace capabilities) (e.g., 19 ). In an illicit setting, knowledge of the structure and scope of a WTN’s structure could help those seeking to limit a WTN’s actions.…”

Wildlife trafficking, whether local or transnational in scope, undermines sustainable development efforts, degrades cultural resources, endangers species, erodes the local and global economy, and facilitates the spread of zoonotic diseases. Wildlife trafficking networks (WTNs) occupy a unique gray space in supply chains—straddling licit and illicit networks, supporting legitimate and criminal workforces, and often demonstrating high resilience in their sourcing flexibility and adaptability. Authorities in different sectors desire, but frequently lack knowledge about how to allocate resources to disrupt illicit wildlife supply networks and prevent negative collateral impacts. Novel conceptualizations and a deeper scientific understanding of WTN structures are needed to help unravel the dynamics of interaction between disruption and resilience while accommodating socioenvironmental context. We use the case of ploughshare tortoise trafficking to help illustrate the potential of key advancements in interdisciplinary thinking. Insights herein suggest a significant need and opportunity for scientists to generate new science-based recommendations for WTN-related data collection and analysis for supply chain visibility, shifts in illicit supply chain dominance, network resilience, or limits of the supplier base.

“…Simulation modeling is a useful tool in studying issues related to the defect resolution process, workforce staffing levels and system performance (Antoniol et al, 2004;Zhou, 1988;Abdel-Hamid, 1989, Melouk, Raja, & Keskin, 2010. In a simulation model, the unpredictable arrivals and resolution times of the software defects are represented by a process flow in which entities (defects) flow through the system (Kouskouras & Georgiou, 2007).…”

The effective management of software maintenance processes involves decisions about workforce levels, skill and expertise mix of developers, assignment of defect resolution tasks, and monitoring key system performance measures. This research uses a queuing based simulation approach to study these managerial issues. Using the data archives of a large global software organization, an empirical study of the historical defect reports and management decisions is conducted. A task-resource capability alignment scheme is developed that captures the defect complexity and skill/experience capabilities of software maintainers. The results of the empirical-computational study show that the defect arrival/reporting process affects the resource utilization and the time a defect spends in the system. The results also highlight the role of dedicated and shared resources on the system performance and indicate that replacing an experienced and skilled developer requires a significant order of magnitude increase in the maintenance workforce.
