The following statements were made by SISCOG customers, in result of their experience with our CREWS Based system.

"First of all I would like to thank you for your efforts on the delivery of the spring release. We are very content with the flexibility of CREWS regarding adapting to the new rules. I think that this is a perfect example of the benefits of using rules to customise the behaviour of an expert system."

"CREWS was used to create guards duties and rosters for all local trains in Oslo and Trondheim. No other method was used. Thus, here the system was in full production. Approximately 2.500 duties were created over a period of two weeks by one planner assisted by Kjell Asgeir Moum from the TPO project. These duties were subsequently placed in rosters"

"With the assistance of CREWS we have been able to plan extra trains without any increase in Driver establishment. Had we not increased the service frequency we would have been able to achieve an annual saving of two Drivers (£60,000 per year). We have achieved a great improvement in the accuracy of data and therefore the outputs. The project has given a far greater understanding of the diagramming rules and therefore the possibilities for change that we may achieve in future discussions with trade unions. It has enabled us to fully document all the rules and constraints previously stored only in peoples memories and lost when they leave. CREWS is giving us better statistical information so that we may answer questions like how productive are our drivers. I firmly believe that SISCOG have the right approach to solving our planning problems with the correct balance of user decision and computer programme assistance. The use of graphics helps the user see the bigger picture, which may otherwise be missed when the information is presented as a text. We need to remind the senior management that the place to invest is in planning so that we may achieve better performance throughout the company"

"DSB S-tog a/s entered into a contract with SISCOG in September 2001. According to this contract, over a period of 3 years, SISCOG will deliver a customized version of CREWS. The first 6 months of the CREWS-project is performing in a very satisfactory way and the implementation of the first modules is already completed. The users have already been trained and are very approved of the system.
Therefore S-tog is looking forward to have the benefit of using CREWS in planning duties."
