Virtual Operator Models For Off-Highway Machine Virtual Prototyping, Yu Du, Michael C. Dorneich, Brian L. Steward Jul 2017

Virtual Operator Models For Off-Highway Machine Virtual Prototyping, Yu Du, Michael C. Dorneich, Brian L. Steward

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Increasing demands on the world‘s resources require the design of off-highway machines that provide greater functionality and productivity along with greater efficiency. Model-based or virtual design provides a means for achieving these design improvements with reduced time and costs. However, virtual design is often limited by the fidelity with which human operators are modeled. A greater understanding of how highly skilled operators obtain high machine performance and productivity can inform machine development and advance agricultural and construction machine automation technology. This research investigated how machine operator expertise, strategies, and decision-making can be integrated into operator models that simulate authentic ...

A Lot Aggregation Optimization Model For Minimizing Food Traceability Effort, Maitri Thakur, Lizhi Wang, Charles R. Hurburgh Jr. Jun 2009

A Lot Aggregation Optimization Model For Minimizing Food Traceability Effort, Maitri Thakur, Lizhi Wang, Charles R. Hurburgh Jr.

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

This paper proposes a lot aggregation optimization model for minimizing the traceability effort at a grain elevator. The problem involves blending of bulk grain to meet customer specifications. A mathematical multi-objective mixed integer programming (MIP) model is proposed with two objective functions. The objective functions allow in calculating the minimum levels of lot aggregation and minimum discounts that need to be applied to a shipment when the customer contract specifications are not met. Constraints on the system include customer contract specifications, availability of grain at the elevator and the blending requirements. The solutions include the quantities of grain lots from ...

To compete in a global marketplace, manufacturers are increasingly turning to advanced manufacturing techniques to increase productivity and gain a competitive advantage. This trend requires management to be able to make decisions based on proper quantitative analysis of data. In the manufacturing process, control of variation with an increasingly high degree of precision demands an improved degree of measurement effectiveness. Measurement Systems Analysis (MSA) is a collection of statistical methods (which includes the Gauge Repeatability and Reproducibility study) for the analysis of measurement system capability (Automotive Industry Action Group [AIAG], 2002; Smith, McCrary, & Callahan, 2007).
