Abstract:

A method of updating a supply plan used to process customer requests in an available-to-promise (ATP) system. In one embodiment the method comprises updating a model of a supply chain process for one or more products sold by the ATP system and copying a current supply plan used by the ATP system to process customer requests to create a second supply plan. Thereafter, a first plurality of customer requests is received and orders from the requests are processed by the ATP system against the current supply plan while running the updated model of the supply chain process with the second supply plan as part of a process that creates a new supply plan. After the new supply plan is created, the new supply plan is synchronized with the old supply plan by synchronizing orders from the first plurality of customer requests scheduled against the old supply plan into the new plan while order promising continues against the old plan. The synchronizing process is stopped prior to synchronizing every one of the orders in the first plurality of requests into the new supply plan. Thereafter, all remaining orders from the first plurality of requests not synchronized during the synchronizing process are synchronized into the new supply plan while the ATM system temporarily stops promising orders. After the remaining orders from the first plurality of requests are synchronized, old supply plan is replaced by the new supply plan so that the ATP system processes future customer requests against the new supply plan.

Abstract:

A vertical cavity surface emitting laser (VCSEL) includes a substrate having an aperture that allows light generated in an active layer of the VCSEL to exit the VCSEL after propagation through a first set of semiconductor layers. The VCSEL further includes an opaque bottom layer that blocks light generated in the active layer and propagated through a second set of semiconductor layers. The opaque bottom layer can be attached to a heat sink for heat dissipation thereby allowing the VCSEL to be operated at high power levels. The active layer is sandwiched between the first set of semiconductor layers and the second set of semiconductor layers. Unlike a traditional VCSEL where only certain wavelengths of light can propagate through a solid substrate that is “transparent” to these particular wavelengths, the aperture provided in the substrate of a VCSEL in accordance with the disclosure allows for propagation of many different wavelengths.
