Embodiment Construction

[0019] The present invention generally provides methods and apparatus for workflow scheduling. Workflow scheduling systems, such as computer systems, are used to coordinate and schedule tasks in complex scheduling environments. The system accepts incoming indications and dynamically schedules the indications according to the resource constraints required by the indication as well as any constraints of the indication itself. An indication may be any variable input into the scheduling system for which the scheduling system seeks scheduling and / or optimization results. Here, the flow can be an instruction, or a part of an instruction, and can be considered as a variable in the CSP. A constraint can be any condition that a solution to a scheduling problem attempts to satisfy. A resource may be an item (eg, a person, equipment, etc.) used to complete an instruction.

[0020] Various embodiments related to medical workflow scheduling are shown in FIGS. 1-7. It will be appreciate...

Abstract

Methods and apparatus are disclosed for workflow scheduling. A workflow scheduling system, such as a computer system, is used to coordinate and schedule tasks in complex scheduling environments. The system accepts incoming orders and dynamically schedules them according to the constraints of the resources required for the order and any constraints of the orders themselves.

Description

[0001] This application requires the serial number No.60 / 804,040, the contents of which are hereby incorporated by reference in their entirety for all purposes. technical field [0002] The present invention relates generally to workflow scheduling, and more particularly to medical workflow in a distributed healthcare environment. Background technique [0003] Workflow scheduling is generally viewed as a Constraint Classification Problem (CSP), where a set of variables and the possible values ​​of these variables and a set of constraints define the CSP. The solution to CSP is to assign variables such that all constraints are satisfied. Algorithms used in solving CSP include backtracking, iterative improvement, and propagation constraints. These algorithms are enhanced using heuristics and / or domain knowledge. [0004] Specialized CSP algorithms (eg, distributed CSP algorithms) are used when the knowledge of variables and constraints is distributed over multiple actors. ...
