Abstract: This invention provides a method for ranking contextual data of a plurality of data packages in a Knowledge Management System (KMS) as a computer system configured to store information on the maintenance of an apparatus, wherein each data package of the plurality of data packages includes a data part relating to maintenance of the apparatus, a first metadata part for the data part having a first metadata value and representing a first contextual information type and a second metadata part for the data part having a second metadata value and representing a second contextual information type, the method comprising the steps of: receiving a first and second relevance value for the first and second contextual information type respectively for a first data package, wherein the first and second relevance values represent the relevance of the first and second contextual information types of the first data part to the maintenance of the apparatus; receiving a third and fourth relevance value for the first and second contextual information type respectively for a second data package, wherein the third and fourth relevance values represent the relevance of the first and second contextual information types of the second data part to the maintenance of the apparatus; determining a first ranking value for the first contextual information type based on the first and third relevance values; determining a second ranking value for the second contextual information type based on the second and fourth relevance values; and storing the first and second ranking values in the KMS. The present invention also provides a method for retrieving data packages, including the steps of: receiving a data package request including a first metadata value for the first contextual information type and a second metadata value for the second contextual information type; and retrieving a first data package of the plurality of data packages based on at least one of the first and second metadata values of the data package request, the first and second ranking values, and at least one of the first and second metadata values of each data package of the plurality of data packages.

Abstract: The present invention provides a method which can be used to optimise the delivery of series over communications networks. Tasks which need to executed within a short timescale and those which are not due to be executed for a long time are excluded from the optimisation process. A score is determined, using fuzzy logic, for each task and its related resources and for each resource and its related tasks. This score is then used to determined which tasks should be optimised.

Abstract: A computer implemented method of navigating a digital representation of a spatial environment by a user in which a portion of the digital representation is rendered by a rendering computer system for visualization by the user. The method including accessing a digital model of the spatial environment including a specification of each of a plurality of virtual resources in the spatial environment, each specification identifying at least a location of a resource in the spatial environment and at least one trigger criterion for determining when a resource is accessed by the user; monitoring the satisfaction of trigger criteria for the plurality of virtual resources; and responsive to the monitoring, determining the portion of the digital representation for rendering by the rendering computer system for visualization by the user.

Abstract: A computer implemented method of determining non-intersecting primary and secondary routes between source and destination nodes in a communications network. The communication network represented by a graph data structure of nodes and edges, the edges having a weight corresponding to a resource involved in traversing the edged. The method including: defining a population set of primary routes, wherein each primary route in the population set identifies a secondary route based on a greedy route-finding algorithm applied to the graph having edges in the primary route excluded from the graph, such that the primary and secondary routes are non-intersecting routes through the graph; applying a genetic algorithm to the population set to iteratively select and crossover one or more pairs of primary routes in the population set; and selecting, from the population set, a primary route and corresponding secondary route having a lowest aggregate weight of edges.
