I've started a new company (Focused Objective) and published another book on the topic of Monte-carlo simulation of software development projects and portfolios. It covers introductory and advanced simulations using the new language SimML. If you want to understand how to employ simulation to make better staff, cost and date forecasts, this book will help you.

Its available from Amazon here -

 Forecasting and Simulating Software Development Projects: Effective Modeling of Kanban & Scrum Projects using Monte-carlo Simulation.
