摘要:
A production planning method inputs demands for products. The demands have multiple due dates, and the multiple due dates have different priorities. The method performs an explosion process utilizing linear programming and heuristics to identify demands for components that are used to make the products (the explosion process maintains the multiple due dates and corresponding priorities for the components) and performs an implosion process utilizing linear programming and heuristics to assign resources to the components considering the multiple due dates and corresponding priorities.

The invention disclosed comprises a method for encouraging fair sharing of limited material inventory and capacity between multiple customers when creating a production plan. the invention allocates resources among competing demands in a linear programming production planning system by first classifying the demands into fair share sets, wherein all demands within each set have the same priority, calculating the cumulative demand for each resource within each set, and then allocating the resources to the demands in order of fair share set priority. If, during the allocating process, the supply of a given resource cannot satisfy a given cumulative demand of a given set, the given resource is allocated proportionally (e.g., evenly or according to usage proportions) among all demands that contribute to the given cumulative demand within the given set. This is an advanced planning system for optimizing established planning objectives (e.g., customer service, short lead times, low inventory, and prioritized allocation of supply and capacity) to compute a feasible production plan for the enterprise.

The invention provides a method of rescheduling timing of when items on purchase orders are scheduled to be received in a linear programming production planning system. This methodology performs a pre-processing rescheduling of the timing of purchase order receipts into the earliest time period allowable in a pre-processing step. After this pre-processing, the invention solves the core production planning system equations using the rescheduled purchase order receipts. Then, the invention performs post-processing rescheduling, which sorts the purchase order receipts according to rescheduling flexibility, and subsequently sequentially reschedules the timing of each of the purchase order receipts in the order established by the sorting process. This process of sequentially rescheduling reschedules the timing of purchase order receipts into the latest time period allowable.

The invention provides a method and system for determining a production plan that includes a first step that determines the minimum number of manufacturing starts that are required to meet contractual obligations; and a second step which determines a production plan satisfying the minimum manufacturing starts together with other customer demands. More specifically, the invention presents a method of allocating production starts (e.g., wafer starts) in a manufacturing facility (e.g., wafer foundry) using a linear programming production planning system which performs a first stage of linear programming to satisfy only contractually mandated minimum production starts constraints followed by a second stage of linear programming to satisfy the additional constraints, once the minimum starts constraints are satisfied.

The invention disclosed here is a method for achieving simultaneous consideration of multiple independent dates associated with a single demand. The method iterates through the demands to match the demands with the supply quantities respecting demand priorities which vary over time and demand quantities which may perish over time. One embodiment of the invention allocates demand to supply through an iterative process beginning with earlier demand requirement dates and concluding with later demands which may preempt supply from earlier demands depending upon their relative priorities. An additional embodiment transforms the demands to create multiple demand records, each having an associated priority, such that a single original demand record is transformed into a plurality of related demand records, each having an associated priority. The component supply quantities are accumulated into period ending inventories. The method matches the multiple demand records (in priority sequence) to the period ending inventories.

A vehicle door latch assembly is disclosed herein, having: a fork bolt movably secured to the latch assembly; a detent lever movably secured to the latch assembly, the detent lever being capable of movement between an engaged position and a disengaged position, the detent lever retains the fork bolt in a latched position when the detent lever is in the engaged position and an engagement surface of the detent lever contacts an engagement surface of the fork bolt; an inertia block out assembly for preventing the detent lever from moving into the disengaged position when the inertia block out assembly is in a blocking position; and a manual override mechanism for the inertia block out assembly, wherein the manual override mechanism requires at least three independent actions to be performed to move the inertia block out assembly from the blocking position to an unblocking position.

A therapeutic device for relieving pain and providing a curative healing effect includes a motor for rotating at least one magnet to generate a magnetic field, micro-vibrations and audible acoustic tones. A shaft couples the at least one magnet to the motor. In one embodiment, the at least one magnet is coupled to the shaft in an offset configuration with respect to a centerline of the shaft thereby generating micro-vibrations in the form of oscillating inertial loads. The therapeutic device includes a light source for generating a photonic light field in an optical light spectrum.

Allocating limited manufacturing resources to achieve a feasible production plan that is consistent with customer demand is a difficult and common problem faced in many manufacturing industries. For large-scale multi-stage manufacturing systems, existing methods are typically based either on allocating limited resources sequentially, according to a priority ranked list of production starts, or on linear programming based models. The output of such planning models is a production plan which specifies the quantity of each part to produce at each plant, using resources available to the enterprise. Typically there are lot-sizing rules defining the permissible production start quantities. The invention disclosed herein is a method for applying these rules to the lot-sizing of production starts within a linear program. It employs advanced heuristics that consider both established operational objectives (e.g. customer service, short lead times, low inventory, and prioritized allocation of supply and capacity) and lot-size rules to efficiently compute a feasible production plan for the division.

Dental implant systems for releasable attachment of dental prostheses are shown and described. Each of the dental implant systems includes an implant body, a prosthesis body, and an abutment body with a locking device. The locking device includes a magnetically attractable member having a first end coupled to a spring and a second end. The magnetically attractable member is moveable between a locked position and an unlocked position. The dental implant system further includes a void configured to receive the second end, the magnetically attractable member being at least partially disposed within the void in the locked position, the magnetically attractable member being free of the void in the unlocked position.
