Reliable Driving Operations Through Harmonised Workshop and Depot Management
Reliability, quality, efficiency and sustainability are pivotal challenges facing public transport companies. Consequently, companies that link all the related processes in an optimized way have an advantage. The coordination of operations and workshops holds great potential and benefits all involved.
Ensuring daily operations, meeting passengers’ increasing quality demands, and reducing costs: Transportation companies are facing many and varied challenges which are almost impossible to meet without the support of information technology. The integrated interaction of the various departments and IT systems is more crucial now than ever before. This is the only way to leverage all areas of potential. Depot Management Systems (DMS) play a key role here.
A DMS monitors and controls all processes in a depot, from vehicle arrival and supply through repair and storage.
For example, a DMS can be used to order and block vehicles for workshop tasks and to classify the vehicles’ operational capability at the same time. Up to now, however, the selection of vehicles for delivery to the workshop has usually been carried out solely via the data-carrying (master data) systems such as those from SAP, Microsoft Dynamics NAV or Maximo which follow standardised rule-based maintenance or cleaning intervals.
These systems do not know or take the on-site operational situation into account when planning. Even special workshop resources that may be relevant to a job are not included in the selection process. This is further complicated by the fact that detailed planning of work processes in the workshop itself is frequently done manually using analog planning tables.
In simple terms, this means:
Workshop activities and operational requirements are characterized by numerous media discontinuities and lack coordination.
The consequence: Vehicle bottlenecks are more likely and the utilization of workstations and employee capacities in the workshop is uneven. A look at practice shows that vehicles which cannot be processed due to a lack of resources are nevertheless reserved for processing by the workshop on a daily basis. This means that vehicles are unavailable for dispatch (damaged in some way that prevents their use) on a regular basis, causing bottlenecks for no reason.
Operational Business Has Priority
Therefore, considerable potential can be leveraged by automating and harmonizing these processes. A system that is also aware of the operational situation in the depot should be introduced to take over the planning of workshop orders. In this context, it makes sense to expand the Depot Management System used, which builds a bridge between
- the workshop,
- operations and
- the systems used in each case.
Solutions that monitor the current operational situation in real time and reliably provide vehicles for scheduled workshop appointments using optimizations have an advantage.
In addition to interfaces for importing and exporting workshop orders, planning resources and fault information, a corresponding add-on module should also include a graphic planning table. It provides an overview of the current occupancy of the workstations in the workshop and utilization of employee capacities.
For instance, if a vehicle is needed for operational purposes, the DMS can overwrite the leading system’s workshop order and postpone it so that the timing suits. In parallel, it can reserve another vehicle for the workshop based on the known, operational requirements and thereby ensure utilization of the workstations and employee capacities. This enables the extended workshop management to take account of the numerous unplanned orders that come in throughout the day and allows for continuous readjustment of the solution calculated statically in the morning.
Automatic Job Planning Ensures Optimum Capacity Utilization
This allows criteria to be assigned different priority levels during vehicle selection. Ensuring operational running is always top priority. As such, this criterion is to be regarded as a restriction: If a vehicle is in high demand in operations due to operational circumstances and the earmarked deadline has not yet been exceeded, it cannot be set aside for the workshop.
In contrast, criteria such as compliance with specified
- inspection and
- cleaning intervals, as well as
- the requirement to utilize the workshop’s capacity evenly
are assigned different priority levels in the decision-making process. These criteria may be defined individually, depending on the availability of resources, especially those such as work statuses, personnel or tools. Finally, the process of finding solutions is completely automatic and the module only generates reports if conflicts which cannot be resolved automatically arise. These conflicts are automatically postponed to the future to allow the employees in charge to search for solutions and respond in a non-pressurized manner.
Thus, the previous planning of work steps manually using an analog planning table in the workshop can be replaced by a digital Gantt display.
It provides an overview of work status occupancy as well as the utilization of employee work capacities. Work orders can also be manually assigned to days in table format and via suitable dialog boxes, as well as in combination with existing assignments.
Integrated Workshop Management Ensures Driving Operations
By integrating operational workshop management into the DMS, vehicles and required work can be consistently tracked within one system. This eliminates the need for paper documents and manual data transfers to a second system. More precise planning and short response times prevent vehicle shortages, which in turn ensures that the driving operations run smoothly.
The use of intelligent decision-making software also allows for the balancing of conflicting goals and the calculation of balanced results. The simultaneous transition from manual work scheduling to an automated system in the workshop also helps optimize the utilization of individual work statuses and employee capacities. Additionally, connections to existing workshop management systems, for example those for commercial processing, can be maintained.

More Room for Maneuver
Linking operations and the workshop via an operational workshop management module opens up considerable efficiency potential. A particularly valuable aspect is the integration of a multi-criterion decision-making aid that allows companies to individually prioritize and weight the planning parameters that are relevant to them.
This solution, which is currently unique on the market, provides transport companies with investment security for existing IT systems in the workshop.
