A system and method of allocating a job submission for a computational task to a set of distributed server farms each having at least one processing entity comprising; receiving a workload request from at least one processing entity for submission to at least one of the set of distributed server farms; using at least one or more conditions associated with the computational task for accepting or rejecting at least one of the server farms to which the job submission is to be allocated; determining a server farm that can optimize the one or more conditions; and dispatching the job submission to the server farm which optimizes the at least one of the one or more conditions associated with the computational task and used for selecting the at least one of the server farms.

Environmental and computing cost reduction with improved reliability in workload assignment to distributed computing nodes

Techniques are presented for rescheduling manufacturing releases. A plurality of release information elements are identified based on a first run of a first advanced planning system. The release information elements comprise dates of planned manufacturing release and quantity. The plurality of release information elements are sorted based on associated demand-likelihood factors and a plurality of sorting criteria. Swapping candidates are selected and swaps are performed based on the demand-likelihood factors and at least one swapping constraint. The plurality of release information elements are then fixed and output as results. A second run of an advanced planning system is optionally performed before output and may include stability features.

Systems and methods of adjusting the order of product manufacturing and rescheduling release dates

Approximating cycle times within a material flow network is disclosed. One embodiment includes assigning an approximate cycle time for completion of a part number PN within the material flow network by using a model that rounds the approximate cycle time to a nearest aggregate time period and adjusting the assigned approximate cycle time based on a mathematical function representing an aggregate accuracy of an aggregation of cycle times throughout the material flow network.

A method and computer program product for scheduling product lots through operations of a manufacturing line. The method including: selecting a set of sequential operations required to manufacture the lots; partitioning the product lots into designated lots and non-designated lots; and generating a release schedule for each of the non-designated lots into one or more operations of the set of sequential operations; generating a release schedule for each of the designated lots into each operation of set of sequential operations such that for each designated lot a total amount of time measured from completion of a first operation of the set of sequential operations through start of a last operation of the set of sequential operations does not exceed a target amount of time for the designated lots.

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.

Supply consumption optimization and multiple component utilization

A method and computer program product for scheduling product lots through operations of a manufacturing line. The method including: selecting a sequential subset of a set of sequential operations required to manufacture the lots; partitioning the product lots into designated lots and non-designated lots; and generating a release schedule for each of the non-designated lots into one or more operations of the sequential subset of the set of sequential operations; generating a release schedule for each of the designated lots into each operation of the sequential subset of the set of sequential operations such that for each designated lot a total amount of time measured from completion of a first operation of the sequential subset of the set of sequential operations through start of a last operation of the sequential subset of the set of sequential operations does not exceed a target amount of time for the designated lots.
