Constructive Solution Methodologies To The Capacitated Newsvendor Problem And Surrogate Extension, Pinyuan Shan

Dissertations

The newsvendor problem is a single-period stochastic model used to determine the order quantity of perishable product that maximizes/minimizes the profit/cost of the vendor under uncertain demand. The goal is to fmd an initial order quantity that can offset the impact of backlog or shortage caused by mismatch between the procurement amount and uncertain demand. If there are multiple products and substitution between them is feasible, overstocking and understocking can be further reduced and hence, the vendor's overall profit is improved compared to the standard problem. When there are one or more resource constraints, such as budget, volume or weight, …

Budget Gaming: Politics, Ethics, And Compensation, Gretchen Decker

Dissertations

Practitioners are frustrated with the budgeting process, frequently complaining that budgets cause undesirable and political behaviors in the organization (Jensen, 2001). One of the most frequent problems is budget gaming, which critics consider non-value added and frustrating. In a 2010 survey, over 95% of respondents acknowledged that budget gaming exists at least “occasionally” (Libby & Lindsay, 2010). Previous studies indicate budget gaming is frustrating, prevalent, and wasteful (Hansen et al., 2003; Libby & Lindsay, 2007; Neely et al., 2003).

I conducted an experiment to investigate organizational influences (organizational politics, compensation condition, ethics attestation) and their impact on budget gaming. The …

Higher Education Business And Technology Leaders’ Behaviors That Drive Outcome Alignment, Katherine Lynch-Holmes

Dissertations

Higher education institutions (HEIs) face unprecedented challenges, including capacity alignment, financial sustainability, and even public confidence (Grajeck & Brooks, 2020; Grawe, 2019; Oblinger, 2019; Simone, 2020, Wheeler, 2020, Witt & Coyne, 2019). Financial challenges force HEIs to reduce costs by making decisions like cutting programs, laying off staff or merging institutions to reduce operating costs (Chen et al., 2019; Sellingo, 2017; Witt & Coyne, 2019). Higher education leaders (HELs) must act as trusted partners and broker technology to align processes, support, and outcomes (Luftman 2000; Petkovics, 2018; Reinitz, 2019). Unfortunately, higher education’s business-technology (BITA) alignment remains lower than other national …
