The objective of vfFailurePrevention is to automatically detect equipment maintenance or failure events by using data analysis algorithms. As a result, it triggers the appropriate monitoring process by sending notification alarms to the corresponding actors.


The vfFailureManager application main goal is to automatically register the failures of the Tabber Stringer machine in a production line by using several PLC data and notifying the users with an alarm when a failure is detected.


The vfStockPolicies application main goal is to manage company spare-parts’ needs and stocks, and alert the staff when the stock is lower than a minimum defined for each spare-part.


The main objective of vfProductionFollowUp is to calculate production KPI’s such as productivity, availability, performance, or quality of the Tabber Stringer and monitor these values.


The main aim of vfMaintenanceCalendar is to schedule a maintenance calendar for the Tabber Stringer machine and support the communication of maintenance operations between MASS and its customers.

MASS wishes to optimise their business model in relation to the maintenance process. Although the most important aspect of maintenance is the ability to offer a fast and high-quality service, there is also the possibility to save money by reducing costs and getting better gross margin. In addition, with a MASS advanced maintenance service, MASS customers are able to use the productionline in a more efficient way.

The first aspect to be improved is the failure diagnostic, in terms of quality and response times, in order to reduce engineering support operational costs and photovoltaic (PV) module manufacturing costs. This improvement can be achieved by adoption of new communication tools for data exchange. In a near future, the integration of prediction capabilities can provide greater advantage to these cross connected systems.

In the new process model, the main communication mean will be a collaborative platform, connected to the machine, able to notify the client that an error may occur or has already occurred. This intervention procedure grants maintenance team an easy access to the machine, offering information about machine failures and actions applied in the past.

Another key point for MASS, in order to improve maintenance related earnings, is the efficient spare part stock management as well as their shipping and distribution management.
