This article introduces a decision model as a multistage, stochastic linear program, integrating both financial and non-financial performance measures into the process of investment planning via the triple bottom line framework. The model developed enables decision makers to create an optimal balanced investment portfolio considering stakeholder priorities together with financial performance of investment projects. As a stochastic program, the model considers uncertainty explicitly, which is not an aspect of previous models. The article provides an application of the model to a local government in the city of Pittsburgh as a case study discussing the implications for managers and policy makers.
