摘要:
A device for testing elongated objects, particularly wires, optionally with cross-sectional irregularities, which has a rotating test head traversed by the object and on which is provided a probe, particularly an eddy current probe, provided on rotary probe holding means and guided on circular paths about the object. For the change of the radial spacing between the object and the probe with the test head rotating, externally controllable e.g. by a sensor for irregularities, the device has a switching device with two inherently stable switching states, whereof one can correspond to a testing position near the object and another to a raised position further removed from the object and which can be rapidly set for protecting the probes.

A rotor mounting on one end of a shaft, particularly a shaft end of a centrifugal pump unit, in which an adjusting surface and at least one contact surface are constructed on the shaft end, and in which a rotor hub is provided at least on the end facing the shaft with a central bore having an internal thread. The rotor hub is attached to the shaft end by a screw connection. The shaft has a central bore (16) having an internal thread (17) at least on the end facing the rotor hub (12); a threaded pin (18) constructed as a separate component is disposed in both central bores (13, 16) in a connecting, torque-transmitting and force-transmitting manner, and the rotor is aligned on the shaft solely by the adjusting surfaces (20) and contact surfaces (21).

The invention provides methods and apparatus, including computer program products, for of determining a possible lot size of units with respect to a fixed date for a chain of at least two process steps, each process step requiring a respective assigned resource, and consuming a respective time per unit for being performed by the respective assigned resource, where the process steps are sequentially dependent on each other. This is achieved by the following: (a) determining, for each resource, a respective time interval of availability during which the respective resource is continuously available, each time interval being limited by the fixed date, (b) calculating, for each determined time interval of availability, a respective largest possible number of times the respective process step can be performed by the respective resource, and (c) selecting the lot size of units to the minimum of the largest possible numbers.

In a method for detecting near-surface defects in a test sample consisting at least partly of a ferromagnetic material, a test volume of the test sample is magnetized and scanned for the detection of magnetic leakage fields caused by defects. The test volume is magnetized by means of a magnetic constant field and simultaneously by means of a magnetic alternating field superposed on the constant field. Leakage field test devices suitable for carrying out the method are described.

A system and method are described for performing bucket-oriented capacity checks on resources to determine whether activities can be processed prior to a desired delivery date. For example, a method according to one embodiment of the invention comprises: subdividing a supply chain scheduling timeline for a particular resource into a plurality of time-buckets, each of the time buckets having a specified time period and a specified total capacity supply, the total capacity supply comprising utilized capacity supply which has been consumed by previously-scheduled activities and unutilized capacity supply which is available for processing new activities; in response to receiving a customer request for a specified activity to be completed by a desired date, determining if sufficient unutilized capacity supply exists within one of the time-buckets prior to the desired date; scheduling the specified activity on the resource within the time period defined by a particular time-bucket if sufficient unutilized capacity exists within the time-bucket; and reducing the unutilized capacity by an amount of capacity supply consumed by the specified activity.

Methods, systems and computer program products are provided for allocating resources in a plannable process, wherein a number of resources is used for executing an order comprising a chain of related activities to be executed on the number of resources. In one implementation, a method comprises, for each order, identifying a first activity execution due date for executing a predetermined first activity in the order, scheduling an execution date for each activity according to a just-in-time criterion in correspondence with an activity execution due date of a related activity, identifying a second activity execution date for executing a predetermined second activity in the order that is scheduled according to the scheduling routine, and reversely scheduling an execution date for each activity according to a just-in-time criterion in correspondence with an activity execution due date of a reverse related activity, wherein the second activity execution date is kept fixed as a second activity execution due date.
摘要:
A method and system for managing inventory in a multiple level distribution chain by applying optimization algorithms to a range profile constructed from a formulation of the distribution network and the various elements factored in the network. A formal definition of the optimization problem is defined and several algorithms are proposed for the maximization of the range of coverage profiles. The optimization process minimizes transportation costs and avoid bottlenecks. However, if bottlenecks were to occur, the system prioritizes demands and provides an optimal solution for a monotone distribution of products. The basic function presented involves the steps of initializing the range of coverage profile with a starting value; computing the necessary in-flows necessary to fulfill the profile constraints; constructing the cheapest flow for these demands using a minimum-cost algorithm; and lowering or enlarging the range of coverage profiles until a solution is found.
