Abstract Today’s student population comes from highly diverse culture and socio-economic backgrounds, entering college with a range of life experiences and professional aspirations. The selection of and success upon entering a major is highly influenced by those factors. As society has progressed the principle purposes of the animal science discipline have remained intact but the industry scope has expanded as has the range of background knowledge and experience of students entering the major. To address these changes a data-driven, student-centered curriculum study was conducted. Amongst the study findings was that there exists a gap between existing student knowledge and skills, and faculty expectations upon entering disciplinary core courses, which were deemed necessary to gain proficiency in areas identified by industry stakeholders. In order to bridge this gap, it was a goal of the department to create foundational level courses that would support the department curriculum. Through the collaborative efforts between faculty within the animal science department and members of the university center for teaching excellence, as well as findings from the data generated as part of the curriculum redesign process, two new courses were identified for development: Farm Animal Biosystems and Livestock Production Systems. These courses illustrate a novel approach to addressing the disparity in student background knowledge and skills. Rather than assuming a level of proficiency with skills and addressing gaps in knowledge or vice versa, these key areas have been identified and separated so as to provide students with a solid foundation in both the scientific and applied components of the discipline, thus promoting success within the remainder of the curriculum. Successful completion of these courses will enable student to enter the specialized discipline core classes with a more uniform knowledge base.

This paper introduces a novel approach to Model-Based Diagnosis (MBD) for hybrid technical systems. Unlike existing approaches which normally rely on qualitative diagnosis models expressed in logic, our approach applies a learned quantitative model that is used to derive residuals. Based on these residuals a diagnosis model is generated and used for a root cause identification. The new solution has several advantages such as the easy integration of new machine learning algorithms into MBD, a seamless integration of qualitative models, and a significant speed-up of the diagnosis runtime. The paper at hand formally defines the new approach, outlines its advantages and drawbacks, and presents an evaluation with real-world use cases.

PurposeThis paper discusses how learning-by-doing (LBD) criterion can be used to evaluate the sustainability of supply chains. This paper assesses the impacts of teamwork on the LBD criterion. Besides, the effect of the internship of new labors on the LBD criterion is discussed.Design/methodology/approachThe repeat of a task leads to a gradual improvement in the efficiency of production systems. LBD occurs by accumulating knowledge and skills in multiple periods. LBD can be used to study changes in the efficiency. Efficiency can be improved by accumulating knowledge and skills. In this paper, the LBD criterion is projected on learning curve (LC) models. Furthermore, the LC models are fitted to the supply chains. Each supply chain may have a unique LC model. A minimum difference is set between the current performance of decision making unit (DMU) and the estimated performance of DMU based on DMU's LC. Hence, a point in which the LBD occurs is determined.FindingsThis paper develops an inverse network dynamic data envelopment analysis (DEA) model to assess the sustainability of supply chains DMUs. Findings imply that the LBD criterion plays an important role in assessing the sustainability of supply chains. Furthermore, managers should increase the internships and teamwork to get more benefit from the LBD criterion.Originality/valueFor the first time, this paper uses the LBD criterion to assess the sustainability of supply chains given the LC equations.
