Models and Scientific Explanation

In recent years, there has been an increased focus on the use of models in science.However, little research has been conducted on the role of models in scientific explanation.Recently, an account of model explanation has been developed by Alisa Bokulich (forthcoming).In this thesis, I provide an overview of Bokulich's account and show that it faces several problems.I attempt to expand the view so that many of these problems can be avoided.I conclude that the modified account can mark as explanatory models justified top-down from theory, but perhaps not models built bottom-up from empirical data.
