Production as a Service: A Digital Manufacturing Framework for Optimizing Utilization

In current practice, product developers with customized small batch production needs come across the problem of finding capable and flexible manufacturers, whereas manufacturers face underutilization due to inconsistent demand. This paper presents a Production as a Service (PaaS) framework to connect users (consumers or product developers) who have customized small batch manufacturing needs with manufacturers who have existing underutilized resources. PaaS is a cloud-based, centralized framework based on a service-oriented architecture that abstracts the manufacturing steps of a product as individual (production) service requests. Using PaaS, the user is able to reach many capable manufacturers at once and receive quotations for the production request. On the other end, PaaS reduces the effort required to find new customers and enables the manufacturers to easily submit quotations to increase the utilization of their resources. The functionalities and concepts defined in this paper are illustrated through case studies. Note to Practitioners-In order to transition product fabrication from the design phase to manufacturing, there is a need for identifying capable manufacturers with available resources that could be paired with user requirements. We propose Production as a Service (PaaS) in this paper and present initial implementations of the front-end and back-end components with a customizable optimization algorithm. Proposed abstractions and data structures make PaaS a unique, efficient, and intellectual property preserving framework. The current implementation of the framework has been tested with new designs. The PaaS framework has the potential to scale over a large network of manufacturers to effectively coordinate geo-distributed manufacturers for custom manufacturing needs.
