    An MGTS 352 introduction to Constraint management using the Theory of constraints
    (2015) Orchard, Ryan
    The following document presents a methodology for managing constraints (bottlenecks) in systems by way of a set of management principals known as the Theory of Constraints.

    Effectiveness of policies for mitigating supply disruptions
    (2013) Son, Joong Y.; Orchard, Ryan
    Our paper will address the significance of supply chain risk management (SCRM) in a setting where demand is steady but supply is subject to random disruptive events. We focus on the impact that supply disruptions have on supply chain performance by proposing two policies for mitigating this impact - using strategic inventory reserves and ordering in larger lots - and assessing their effectiveness through supply chain model analysis and numerical experiments.

    Experiences from a data-informed approach to configuring online assignments
    (2019) Orchard, Ryan
    Learning Management Systems (LMS) allow for a variety of ways in which online multiple-choice assessments (“tests”) can be configured, including the ability to allow for multiple attempts and options for which of and how the attempts will count. These options are usually chosen according to the instinct of the instructor; however, LMS also provide an opportunity to make data-informed decisions based on data captured by the LMS itself. This paper describes an experience with extracting and analyzing LMS data for determining online test option settings that encourage behaviors that promote learning (and/or discourage behaviors that don’t). The data extraction and cleaning process was relatively straight-forward, but not without some challenges, and required beyond-novice spreadsheet skills. It seems to have been worth the effort, though, as the insights gained led directly to a change in online test administration, and current option settings seem more appropriate and are supported by data.

    Multiple attempts for online assessments in an operations management course: an exploration
    (2016) Orchard, Ryan
    In Learning Management Systems (LMS), tools for online homework assessments include a number of alternatives for the assessment settings, including the ability to permit students to attempt an assessment multiple times, with options for how the multiple-attempts are administered. A specific implementation of online assessments in an introductory Operations Management course, where students were allowed up to two attempts, found that assessment performance was better for students who attempted only once, even when comparing between students of similar ability in the course. A discussion of why this may be, and how minor modifications to the specific assessment settings could change student behaviors, is provided.

    Using homemade, short, fictional cases for teaching the theory of constraints
    (2018) Orchard, Ryan
    For our undergraduate Operations Management course, a lack of case studies meeting our specific needs, coupled with our reluctance to reuse cases too frequently, inspired development of a collection of “homemade” cases. These cases, which focus on application of the Theory of Constraints, are fictional (of necessity) and short (by design); however, we have found that these two characteristics have not limited the effectiveness of the case assignments: They are consistently meeting our pedagogical objectives, including eliciting deliberation and varied responses from students. This paper discusses the motivation for developing homemade cases, the nature of the cases (short, fictional) and associated implications, advice for development and implementation, and feedback from students.
