Controlling Manufacturing Plants with Manufacturing Execution Systems

Abstract

A method and system for controlling a manufacturing plant with a manufacturing execution system by executing a given workflow comprising: a) providing a plant designer for modeling a representation of a manufacturing plant through a set of equipment objects and through at least one workflow Application; b) Provides a composite entity called a plug-in for extending the characteristics of the equipment object; the plug-in makes the interface visible including the configuration, a set of attribute elements, and a set of functional elements; c) at maintenance time, design a set of equipment objects A set of plug-ins that can be used; d) associate at least one plug-in for at least one equipment object at maintenance time; e) define a given workflow according to a given customer requirement at maintenance time by a plant designer, said given The workflow includes at least one interaction with at least one element of the at least one plug-in associated to the device object; f) at runtime, executing the given workflow and performing at least one interaction with the at least one element of the at least one plug-in associated with the device object interact.

Description

technical field [0001] The present invention relates to a method and a system for controlling a manufacturing plant with an MES system by executing a given workflow that satisfies a given customer requirement. Background technique [0002] To be more competitive in today's industrial automation world, manufacturing companies need to simultaneously reduce time to market, increase process visibility and production flexibility, optimize forecasting and scheduling, and reduce scrap, inventory levels and downtime; all All while ensuring optimal quality and production efficiency across all global facilities. [0003] Therefore, in order to meet these demanding goals, manufacturing companies need an integrated IT infrastructure that helps them coordinate production globally and if necessary in real time. Manufacturing execution systems (MES) are often referred to as the IT layer, which integrates business systems (such as ERP) and production control systems. [0004] at Siemens' ...

Problems solved by technology

This advantageously enables logical characterization, but unfortunately still has the drawback of not enabling device characterization, namely the inability to characterize device objects with well-known features

[0019] Thus, in all of the above prior art there is still no link between device objects and production logic beyond mere aggregation, and unfortunately another major drawback is that device objects have not yet been characterized by runtime capabilities

[0020] Another shortcoming is that workflows and rules are good for expressing simple logic, but unfortunately, in complex situations requiring a large number of steps and actions, workflows and rules can become overwhelming for both execution and maintenance. quite heavy
