1. An apparatus for implementation of at least a schedule modeler, the apparatus comprising a processor and a memory storing executable instructions that, in response to execution by the processor, cause the apparatus to implement at least: a task separator configured to receive process-related information describing a process for production of a product, the process-related information describing a logical sequence of tasks to produce respective internal products of the process, at least some of the tasks having a precedence relationship whereby the internal product produced by one task is an input utilized or required by another task, wherein for at least some of the tasks each of which utilizes or requires one or more inputs including temporally at least a last input, the task separator is also configured to separate each of the at least some of the tasks into a closure portion that requires availability of the last input of its task before being initiated, and a distinct precursor portion capable of being initiated before the respective last input is available; and a schedule constructor configured to construct a schedule for execution of the at least some of the tasks, including the schedule constructor being configured to at least: temporally sequence the closure portions of the respective tasks without intervening precursor portions; and prepend the precursor portions to respective, temporally-sequenced closure portions.
