Abstract: A computer-implemented method of representing the availability of resources allocated to an entity includes receiving a planned resource description describing how resources were expected to be consumed by the entity, receiving a consumed resource description describing how resources are actually being consumed by the entity, and generating a graphic representation indicating a correlation between the planned resource description and the consumed resource description.

Abstract: A data model for a supply chain is provided whereby individual working steps in a production process are defined as activities, and organized groups of such activities are defined as orders. Activities are allocated to no more than one resource and contain information concerning the start and finish time for the activity, any resource on which the activity is currently scheduled, and a list of alternative resources, if any. Activities are linked to each other via auxiliary objects, which contain information concerning the minimum and maximum time between activities. Orders may contain input and/or output interface nodes, representing the materials consumed and produced by the offer. Each output interface node representing a quantity of material created from one order is linked via an auxiliary object to respective input interface node or nodes from other orders that are scheduled to receive that material.
