Many industrial and commercial print service providers (PSPs) are dealing with fragmentation of high copy count, low-mix demands to low copy count, high-mix demands due to mass customization and personalization of content. To understand the true dynamics of a changing demand, a stochastic discrete event simulator such as Ptolemy, from UC Berkeley, could be a very useful tool. However, simulation usage presents a high technology and knowledge barrier to solution architects. Additionally, IT requirements such as periodic upgrade and update of software and hardware infrastructure further imperils the use of simulation for solution architects. With the advent of cloud technology and service broker architecture, both problems can be solved effectively. Solution architects can now quantify effects of these changes using simulation-as-a-service (SimaaS) without worrying about simulation and the hardware and software updates.
