Abstract

The invention concerns a device with a supervising unit (10) arranged to handle a rule system for the behavior of an entity (44). The supervising unit (10) comprises at least one storage member (12) in which a set of rules (14) for the behavior is stored. The device also has a user interface (16) comprising first means (18) for presenting information, preferably concerning decisions which are made and/or recommended, to a user. The device is arranged with a first (41) and a second (42) rule handler which can work in parallel with each other. Said first means (18) can simultaneously present information concerning the rule handling which is carried out by the first rule handler (41) and the rule handling which is carried out by the second rule handler (42). The invention also concerns a use, a system comprising a device according to the invention as well as storage media with computer programs for implementing the invention.

4. A device according to claim 2, wherein names which identify said states, rule blocks and/or rules, automatically or in response to a command entered via said second means, are presented to a user with said first means.

5. A device according to claim 4, further comprising means, associated with said first means, for presenting a plurality of names which concern different states, wherein the name of the state in which said first rule handler exists, is marked with a first kind of marking.

6. A device according to claim 5, wherein when the second rule handler is activated by instructions from a user, the name of the state in which said second rule handler exists, is marked with a second, different kind of marking, wherein both the first and second marking markings are capable of being simultaneously presented by said first means.

7. A device according to claim 2, wherein said first means provides a decision support window which includes at least one area which represents a state, wherein the area includes names which identify at least different rules which form part of the state.

8. A device according to claim 7, wherein said area includes at least names of a plurality of rules, wherein the name of the rule or rules which are activated for the moment according to at least one of said first and second rule handler are provided with markings which indicate that the rule or the rules in question are activated.

9. A device according to claim 8, wherein when the second rule handler is activated by instructions from a user, the name of the rule or rules which are activated according to said first rule handler is marked with a first kind of marking, while the rule or rules which are activated according to said second rule handler are marked with a second, different kind of marking.

10. A device according to any claim 7, wherein said area also includes the name of at least one rule block which forms part of the state.

11. A device according to claim 1, further comprising means, operable in response to a command via said second means, for deactivating the second rule handler.

12. A device according to claim 7, wherein said second means includes means for naming at least different rules, the names of the rules which have been named by the user, and which form part of a certain state, being automatically shown within said area, when said area which represents the state in question is shown in said decision support window.

13. A device according to claim 7, wherein said plurality of states (30) are organized in at least one of a network and a hierarchy of states, wherein the device further includes means for allowing a user to modify the states by performing at least one of the activities which include naming states, adding states, removing states, and changing the position of the states in the network or hierarchy, wherein when said decision support window is shown, a plurality of states are automatically shown, and wherein the states are automatically shown in accordance with the modifications of the states which the user has carried out.

14. A device according to claim 1, wherein the rule system is divided into at least one of a plurality of states and rule blocks for different parts of said behavior, the device further includes means, operable in response to an advance user command via said second means for defining that, for a certain state or a plurality of states and/or rule blocks, the rules which form part of the state and/or the rule block shall not be activated automatically, whereby the behavior of the entity in these states and/or rule blocks is always handled manually.

15. A device according to claim 1, wherein one of the rules includes at least one predetermined and preprogrammed premises which can either be true or false and at least one predetermined and preprogrammed conclusions, wherein each premise in the rule is assigned an indicator which can indicate three different conditions, including a first condition that the premise shall be true, a second condition that the premise shall be false and a third condition that it does not matter whether the premise is true or false, wherein at least one conclusion is carried out if all of said premises fulfill the conditions set by the assigned indicators.

16. A device according to claim 15, wherein each conclusion in the rule is assigned an indicator which can indicate two different cases, a first case which indicates that the conclusion shall be carried out and a second case which indicates that the conclusion shall not be carried out, wherein a conclusion is carried out if all of said premises in the rule fulfill the conditions set by the assigned indicators and the indicator of the conclusion indicates said first case.

17. A device according to claim 15, including means, operable on commend from a users, for showing at least one of said rules with said user interface, and further comprising means, operable by a user with the help of said second means of the user interface, for changing the indications of said indicators.
