Equilibrium-Based Workload Balancing For Robust Emergency Response Operations In Metropolitan Areas, Parya Roustaee 2019 Southern Methodist University

Equilibrium-Based Workload Balancing For Robust Emergency Response Operations In Metropolitan Areas, Parya Roustaee

Civil and Environmental Engineering Theses and Dissertations

This thesis presents an equilibrium-based modeling framework for emergency response (ER) workload balancing to achieve robust operation in large-scale metropolitan areas. The problem is formulated as a non-linear mathematical program (NLP), which determines the optimal workload cutoff for each ER station such that the weighted sum of the area-wide expected response time and its variation are minimized. The concept of Marginal Cost of Uncertainty (MCU) is introduced to measure the impact of a station’s workload increase on the area-wide service performance. The solution of the NLP is proved to be equivalent to a state of equilibrium in which all ...

Smithfield Hog Production has several processing facilities across the state of Iowa along with numerous contract finishing farms where producers grow their pigs. The hog manure on these sites is pumped into a slurry store for storage. A slurry store is a 1.2-million-gallon round tank that is 18-feet-tall and 120-foot diameter. Since the slurry store is open to the weather, it accumulates rain, snow, and other types of precipitation.

While evaporation generally equals precipitation, there are some years where precipitation is greater than evaporation. The result is a reduction in manure holding capacity and additional cost to hog production ...

An Aco-Inspired, Probabilistic, Greedy Approach To The Drone Traveling Salesman Problem, Jessica Houseknecht

Senior Honors Theses

In recent years, major companies have done research on using drones for parcel delivery. Research has shown that this can result in significant savings, which has led to the formulation of various truck and drone routing and scheduling optimization problems. This paper explains and analyzes a new approach to the Drone Traveling Salesman Problem (DTSP) based on ant colony optimization (ACO).

The ACO-based approach has an acceptance policy that maximizes the usage of the drone. The results reveal that the pheromone causes the algorithm to converge quickly to the best solution. The algorithm performs comparably to the MIP model, CP ...

Optimization modeling is the process of selection of the best solution to a design problem using predetermined constraints from a set of prospective solutions. Increased computing power has made optimization solvers readily available for business/research needs. For example, Microsoft Excel has a simple, but robust solver. Such solvers can model linear, nonlinear, and integer programming problems that are limited in size. This study shows the use of the optimization model solvers in various research contexts.

Smithfield Foods Inc. was founded in 1936 by Joseph W. Luter and his son Joseph W. Luter, Jr., with the name Smithfield Packing Company. The company name was later changed to Smithfield Foods in 1974. Smithfield Foods Inc. is quite proud of their guiding principles (Responsibility, Operational Excellence & Innovation) and this small excerpt defines their company as a whole, “We will seek fresh ideas in all aspects of business, including ways to work smarter, serve customers better, and make Smithfield a better company.” (Smithfield Foods, 2019).

The issue that we worked on was how swine producers want to decrease the inefficiency of hauling raw manure slurry and increase manure application systems by separating solids and liquids produced in a typical shallow pit barn with an external manure storage system. There is a moderate amount of research that has been done on swine manure separation, but quite a bit of it is outdated. The current application of raw manure slurry is altogether expensive and inefficient by the traditional method of transporting the manure by large tanks, while post-separated manure could be transported further distances more efficiently. The increasing manure application possibilities and transporting regulations have been a large part of the project in the context of the future of swine production.

Given the elements of the project:

  • Minimal research has been completed on current swine manure separation methods
  • Manure separation is expensive, and its feasibility is all dependent on a producer's budget and the overall size of their operation
  • Multiple costs associated with implementing a separation method (Solid & liquid storage, separation equipment, additional labor, etc.)

It is critical for producers/growers to comprehend the true benefits of implementing a separation method at this time before future regulations become required. The cost analysis tool will give producers the capability to view several costs associated with a particular separation method. When adopting a separation method, there two important benefits; higher efficiency of transporting manure farther distance and the cost-effectiveness increase tremendously.

Feed costs in the swine industry are typically 60-70% of the total swine production costs. Feeder adjustment is used to decrease feed costs. When feeders are properly adjusted, the growth rate can be improved while the wasted feed is minimized. Currently, feeders are manually monitored and adjusted by daily caretaker inspection, which is very laborious. Automated adjustment would reduce labor need and allow for the integration of precision management in the future.
