Preventive and proactive planning of PaaS maintenance service teams

This paper employing the Product-as-a-Service (PaaS) paradigm provides a model integrating preventive and proactive management strategies to maintain the required service level availability in Multi Function Device (MFD) offerings. The problems of resource allocation and servicing problems implied by these strategies focus on planning leasing offers that meet an acceptable failure risk level and routing service teams participating in maintenance missions. The aim is to allocate services that provide balanced risk to suppliers and renters, reduce delays, and prioritize urgent cases by routing a fleet of technical vehicles responsible for delivering and receiving service teams without the constraint of requiring the exact vehicle for both operations. The conducted computer experiments demonstrated the effectiveness of the adopted reference model, allowing for increasing PaaS availability and minimizing service costs.
