1 Integrating Maintenance Management Systems (MMS) with Maintenance Decision Support Systems (MDSS) Paul Pisano, Federal Highway Administration William Hoffman, Nevada DOT Richard Glassco, Fred Klein, Andrew Stern, Noblis July 22, 2009 TRB Maintenance Management Conference Contact:

2 What the Talk is About MMS = Maintenance Management System MDSS = Maintenance Decision Support System The untapped potential to automatically exchange data between these two systems 2

3 Agenda Overview of MMS and MDSS Benefits and Issues for Using MDSS data in MMS Benefits and Issues for Using MMS data in MDSS Steps for Data Exchange Options for Developing Data Interchange Capabilities 3

4 Overview of MMS Maintenance Management Programs are used to: track material and labor assets and expenses formulate and choose among strategic maintenance plans Assist with mid- and long-range maintenance decision making: Performance targets Measure outcomes Prioritization of tasks Methods of data input into MMS include: manual entry flat file from other programs mobile data collection from maintenance staff with PDAs mobile data collection from instrumented vehicles 4

6 Current MMS Providers Internal program written by DOTs Complex systems developed under contract to DOTs includes payroll and other personnel asset management functions Commercial programs such as Agile Assets OMS Boshung SCM Stand-alone or combined with Asset Management Programs such as SAP 6

7 Overview of MDSS MDSS is a computer-based decision support tool to aid DOTs actions in snow & ice control An amalgam of data, models, and algorithms Uses weather forecasts, current weather observations, and customized rules of practice Produces road-specific forecasts and recommendations for road treatment Several studies have documented savings in labor hours and materials used for road treatments One less call-out can save $500,000 (10 tons/ld x 50 $/ton x 1,000 trucks) Indiana DOT reports savings: $10m in materials, $1m in labor 7

10 Overview of Integrating MMS and MDSS Not combining two programs into one Feeding MMS inventory and procedural data into MDSS for improving MDSS road treatment recommendations Feeding MDSS treatment recommendations, actual treatments, other real-time conditions into MMS to improve timeliness and accuracy of asset tracking Creating common formats to enable data exchange among MDSS and MMS systems from different providers 10

11 Benefits of Using MDSS Output Data in MMS MMS D MDSS Proposed treatment plans can be entered automatically rather than manually MMS can check feasibility of MDSS recommendation and weigh availability/cost considerations to choose among multiple options Road-specific weather forecasts can improve MMS recommendations Actual treatments can be entered automatically, improving timeliness and accuracy Road conditions from vehicles can support real-time performance monitoring by snow & ice managers 11

12 How Feeding MDSS Data into MMS Would Work MDSS produces road forecasts and treatment recommendations as files These output files are converted to an exchange format and transmitted to MMS MMS reads in data files MMS uses the material, labor, and equipment levels in its inventory levels and checks treatment plans for feasibility If there are multiple possible plans, MMS can compare costs for each MDSS treatment plans used as basis for entry of actual treatments or actual actions are recorded 12

13 Pictorial Concept of Operations for MDSS to MMS Data Transfer MMS D MDSS Road data Forecast data Sensor data Feasible options MDSS Users Road forecasts & treatments Same data formatted for exchange Database of labor and material assets MMS Logistics for treatment plan Plan is executed Amounts of labor & material used Outcome 13

14 Benefits of Using MMS Output Data in MDSS MMS D MDSS MDSS can have the benefit of knowing available inventory levels and locations of treatment materials MDSS can have the benefit of knowing available levels and location of labor and equipment MDSS can adapt treatment rules of practice from MMS to produce treatment plans closer to standard procedures 14

15 How Feeding MMS Output in MDSS Would Work Adapt treatment rules of practice from MMS into MDSS Feed changes in inventory levels and resource availability into MDSS whenever they change in MMS MDSS recommendation could then be based on rules of practice and resource availability 15

16 Pictorial Concept of Operations for MMS to MDSS Data Transfer MMS D MDSS Database of labor and material assets MMS Logistics for treatment plan Rules of practice Updated resource levels Same data formatted for exchange Plan is executed Road data Forecast data Sensor data Feasible options MDSS Users Road forecasts & treatment s 16

17 Operational and Administrative Issues for Data Transfer between MDSS and MMS MMS D MDSS How frequently would the data transfer occur (depends of frequency of MDSS update and MMS update) Does the same office administer both systems? If not, coordination must be negotiated. Are the programs administered at the state, division, or local level? Coordinating across levels may be tricky. MMS frequently resides behind a firewall for personnel security issues Format of data transfer must be developed 17

18 State DOT+ Interviews 18

19 Options for Developing MDSS Interfaces National lab to provide a prototype Hold competition for commercial MDSS providers Investigate Boschung option (both MDSS and MMS) DOTs ask their suppliers to provide the capability Pooled fund pursues open development, e.g., following system engineering process 19

20 Options for Developing the MMS Interfaces MMS D MDSS State DOTs could request the capability from their providers State DOTs build the capability internally Multi-state effort (e.g., pooled fund study) could develop the capability MMS providers pursue development on their own or team up with an MDSS provider 20

21 Conclusions Part 1 MDSS and MMS systems are widely deployed There are multiple providers for both systems The operation of each system could be enhanced with input from the other The data each program uses is similar but not identical 21

22 Conclusions Part 2 Technical issues Must develop common exchange format Must modify programs to use new data Administrative issues Does the same agency operate both MMS and MDSS? Data security issues for in-house MMS Proprietary data or algorithms 22

23 Conclusions Part 3 Several Approaches for bringing about integrated capabilities: Nationally-led effort Designated commercial provider(s) Competition among providers Consortium of state-level users Free-market approach 23
