Food accessibility has been a growing interest by the United States government due to the negative impact on the population’s health such as obesity, chronic illness, and premature death. This thesis investigated existing and potential quantitative food access measurement models to support decisions to improve food access. A gap was identified in research assessing food access measurement methods for policymakers to proactively support actionable decisions to improve accessibility. There was an opportunity to incorporate individual and community considerations that would reflect a more realistic measurement of food access. A proposed integer program was proposed for individual navigation of the food opportunity system in Sedgwick County, Kansas. The formulation considers potential requirements and limitations of individuals seeking food assistance and the food opportunities available to them. The output of the proposed formulation recommends a set of locations and times for individuals to acquire the food they need at minimal cost. Ultimately, the illustration of the use of the life-constrained accessibility in the food opportunity system with a hypothetical sample of individuals with varied characteristics generated from census data. The thesis compares the assessment of access to the conventional perspective. It was confirmed that conventional measures overestimate the individual’s ability to obtain the food they need.
