Abstract: Systems, apparatuses, and methods for providing feedback in an electronic sourcing system. A system is configured to receive a first optimization model whose solution represents an allocation or award of items being bid upon. The first optimization model comprises a plurality of bids and one or more allocation rules representing one or more constraints on the allocation. Subsequent to determining the optimization model is not feasible, the system is configured to compare the one or more allocation rules to a reference allocation. Subsequent to determining an allocation rule of the one or more allocation rules is in conflict with the reference allocation, system is configured to relax the allocation rule in the first optimization model to create a second optimization model, and solve the second optimization model to generate an allocation compatible with the second optimization model.

Abstract: Systems, apparatuses, and methods for providing feedback in an electronic sourcing system. A system is configured to receive bids from users in an electronic sourcing system. Additionally, the system receives one or more rules from the users that describe desired properties of an award of one or more items. Responsive to such input, the system builds a model based at least in part on rules provided by one or more users. If one or more irreducible infeasible sets of constraints are identified in the model, where the one or more sets of irreducible infeasible constraints include the given constraint, information based on said one or more irreducible infeasible sets is output.

Abstract: A knife for a cutting disc in a cutting machine, which disc includes a centrally arranged, penetrating hole and an opening extending in a radial direction. The disc is manufactured from sheet metal and includes a dike-shaped section with a sloping part extending radially from the center of the disc. An attachment element for attaching the knife is arranged along the sloping part. The knife is bent along a bend line running along the longitudinal direction of the knife. The attachment element is present in a section of the knife on one side of the bend line, and a cutting edge is present running along the free edge of the knife. The angle of bend between the sections is such that the section of the knife at which the cutting edge is present is parallel to the plane of the cutting disc when the knife is mounted on the disc.

Abstract: Systems, apparatuses, and methods for managing advanced projects such as optimization-based e-sourcing and resource allocation. A number of components and methods allow a user to specify complex content in a tender or project. Advantageously, manual work outside the system and the need for tailoring an existing system by custom programming is decreased.

Abstract: Cutting disc for use in a cutting machine, including a centrally arranged through hole and a radially extending opening. The cutting disc is manufactured from sheet metal, it comprises a first bent edge extending peripherically around the disc and a second bent edge extending peripherically around the through hole, and the disc includes a ditch-formed section extending radially from the centre of the cutting disc and out to the first bent edge.

Abstract: A cutting device for food processors wherein the processor is a cutting machine for cutting or chopping raw foodstuffs. The machine includes a container. A cutting device that includes a central sleeve-like part is non-rotatably fitted to a driven shaft and carries a cutting tool at its lower end, the cutting tool including knives that extend radially outwards from the sleeve. The cutting device includes a first pair of knives with respective knives extending radially from opposite sides of the central part close to the bottom of the central part. At least one second knife projects radially outwards from the central part higher up from the bottom of the central part than the first pair of knives. The second knife has a shorter bade than the knives of the first pair.

Abstract: A turning device for food processors that include a rotatable cutter to cut foodstuffs to be processed. A stationary container is fitted with a lid, and a tubular member extends upwardly from the container bottom through which a driven shaft extends. The cutter is mounted on the shaft and includes a sleeve-like central part and radially-outwardly-extending cutting knives. The turning device includes at least a pair of strips that extend axially from a tubular holder that is adapted to fit over the central part of the cutter. In use, the turning device is disposed over the central part of the cutter with the holder positioned above the strips. The turning device extends longitudinally relative to the cutter to cover essentially the whole of the central part of the cutter above the position of the cutting knives, and it is stationary relative to the container during operation of the food processor.
