Abstract: A method for analyzing service loss in a rotable supply chain includes receiving, in an inventory management system, an exchange sales order associated with a rotable part. The method also includes establishing a scheduled ship date associated with the exchange sales order. One or more supply chain events associated with an item on an exchange sales order are created, wherein the one or more supply chain events are indicative of the status of the item on an exchange sales order. A cause of service loss associated with the exchange sales order is determined based on the one or more supply chain events if the exchange sales order is not fully shipped by the scheduled ship date. A report is generated summarizing the cause of service loss associated with the exchange sales order.

Abstract: A method for forecasting a demand for rotable parts includes collecting demand data for one or more rotable parts associated with a product inventory. A demand pattern associated with the demand data is identified for each of the one or more rotable parts. A future demand associated with the one or more rotable parts is forecasted for at least one future demand period based on the identified demand pattern. An inventory level associated with each of the one or more rotable parts is established, for the at least one future demand period, a based on the future demand and a predetermined customer service level. The method also includes adjusting a manufacturing schedule associated with the one or more rotable parts based on the established inventory level.

Abstract: A method for replenishing rotable material associated with a parts exchange program comprises receiving replenishment data associated with a part number, and estimating projected rotable requirements for the part number based on the replenishment data. A supplemental quantity of new materials required to meet the projected rotable requirements is determined if the projected rotable requirements exceed an available rotable or core quantity. Future new material requirements for the part number are estimated based on the replenishment data and the supplemental quantity of new materials required to meet the projected rotable requirements. A purchase order for new material is generated based on the future new material requirements if the amount of new material onhand is not sufficient to support new demand and needed rotable supplement material.

Abstract: A voltage switching apparatus and method are disclosed. At least one disclosed method includes providing, when a mode selection signal is in a first state, a first power rail voltage on a first power voltage line and a second, different power rail voltage on a second power voltage line. After the mode selection signal transitions to a second state, a second power rail voltage is provided on the first power voltage line and a switch between the first and second power voltage lines is closed.
