TL;DR: The paper provides an optimal control formulation of the problem and develops necessary conditions for optimality and characterizes the dynamics of optimal price, quality and investment decisions.

TL;DR: A dynamic model in which demand depends on both price and quality is developed, and it is observed that improving operational efficiency softens price increase while quality increases.

TL;DR: In this paper, the authors analyzed an organization that has a well-defined strategy providing a sustainable competitive advantage and found that continuous and simultaneous improvement of operational efficiency and quality is a must and is independent from price setting policies.

TL;DR: A model that considers process quality improvement and setup cost reduction and supports the popular operations paradigm that reducing response time and increasing process reliability are parallel processes.

TL;DR: A version of the economic order and production quantity models when the fraction of defective items is probability variable that either may vary from cycle to cycle, or remains the same as it was in the first period.
