Embodiment Construction

[0032] For the description of the present invention, it is emphasized that Microsoft The .NET Framework is the basic software "skeleton" of a Manufacturing Execution System. Siemens' solution to MES is SIMATIC IT. To explain SIMATIC in short text IT background, I have to mention ISA-95. ISA-95 is increasingly accepted as the world standard for manufacturing execution systems that customers can rely on. SIMATIC IT not only covers ISA-95 functionality but actually uses ISA-95 as a blueprint for its product architecture. Siemens Aktiengesellschaft (SIMATIC IT owners) are active members of the ISA-95 committee that contribute to its continued development.

[0033] SIMATIC IT itself is a collection of software components proposed by Siemens representing a Manufacturing Execution System (MES). The uniqueness of SIMATIC IT is represented by its overall architecture, designed using ISA-95 as the architectural blueprint for implementation. SIMATIC IT Production Mo...

Abstract

A method and a system for executing a scheduled production process having an execution duration within a production schedule executed and controlled by a manufacturing execution system are disclosed, comprising the steps of: a) defining within the production process a resource required for the execution of the production process (STEP1) ; b) defining for the resource a sequence-dependent setup sub-process having a setup duration, a productive sub-process having a production duration and a sequence-dependent teardown sub-process having a teardown duration (STEP2); c) scheduling the production process for its execution with a start-time on a production schedule wherein the scheduled execution duration is the sum of the setup duration, the production duration and the teardown duration (STEP3); d) at a predetermined period prior to or at the start-time of the production process, confirming the production process for dispatching and subsequent executing (STEP4); e) in response to the confirmation of the production process for dispatching, creating individual production processes for the sequence-dependent setup sub-process, the production sub-process and the teardown sub-process, whereby the created individual production processes are linked together by precedence constraints defining a sequence of the created individual production processes (STEP5) ; f) re-scheduling the production schedule through replacing the production process by the created individual production processes (STEP6); and g) executing the re-scheduled production schedule by dispatching the created individual production in the scheduled sequence (STEP7).

Description

technical field [0001] The present invention relates to a method and system for executing a scheduled production process having an execution duration within a production schedule executed and controlled by a Manufacturing Execution System. Background technique [0002] Enterprise Resource Planning (ERP) is a hardware device and corresponding software application used to plan the business resources of an enterprise (i.e. material supply, human resource management, purchases, orders, profits, finance, inventory control, customer management, other items) systems, while the term "shop floor" has been used to denote a system supported, for example, by measuring the number of pieces produced per hour by each machine or its operating parameters, the quality of the parts produced, etc. A system for the control of a single machine involved in a manufacturing process. [0003] A Manufacturing Execution System (MES) is an intermediate layer that provides computing machines and softwar...
