Abstract: In a method and a system for managing product definition updates for controlling a manufacturing process via a MES system, design information entities each defining manufacturing specifications for a specific product and including sets of data concerning different manufacturing steps are downloaded to the MES system. At the first download, first and second MES information entities are created and stored. The first entities have associated second entities each including data for a manufacturing step and include links to the associated second entities. At each update of a design information entity, a differential package including the whole of the data for a set having undergone changes and for newly added sets, and an identification for unchanged sets, is downloaded. A new version of the second entities corresponding to sets having undergone changes and/or additional second entities corresponding to sets of data that have been added are created and stored.

Abstract: We add a new entity Production Parameter History to the ISA-95 Production Schedule Model, thereby extending the model. The new entity stores the recent history of the values assumed by a subset of batch parameters most relevant for production control and resource planning, thus without the ERP system being charged with retrieving the historian from a log or from a warehouse in order to schedule the plant production. Putting together the batch information present in the ISA-95 Segment Requirement and the new Production Parameter History, the MES creates and stores a fully Electronic Batch Record close to a real situation found during product manufacturing. The MES system can provide the Electronic Batch Record to the ERP system through the ISA-95 Production Performance model extended thereof, since a production performance report is made up of a set of one or more Production Responses associated with Production Requests.

Abstract: A system handles conditional dependencies between alternative product segments of a production process modeled within a manufacturing execution system (MES). The system includes data processing units connected to a network and production components. The data processing units run MES software for controlling and monitoring the process. The MES software includes a production modeler embedding time-sensitive dependency information in each product segment to define the start of execution in relation to another product segment. The production modeler embeds in each product segment programmed for alternative execution conditional dependency information and a sequence attribute about the order of evaluation of the specified condition.

Abstract: A method of controlling manufacturing processes in a plant via a MES system includes the step of providing the MES system with a single production-related entity for manufacturing a plurality of products whose manufacturing processes share most of the process workflow and most of the resources. The providing step further contains including into the single production-related information entity, for process stages in which non-shared resources are involved and which are to be performed according to parameters specific for each product in the plurality, information about the parameters to be used for the different products. At the creation of a production order for a specific product, one reads from the single production-related information entity and includes in the order only the parameters specific for that product.

Abstract: A method increases the work performance of a manufacturing executing system (MES) and an enterprise resource planning system (ERP). The method includes forming the enterprise resource planning system to be enabled for planning the business resources of a production plant and for releasing production orders to the manufacturing execution system. The manufacturing execution system is enabled to control and to execute a production process on the production plant according to the production orders. An operation schedule is created by the enterprise resource planning system, the operation schedule represents a production workflow of the production process. A number of operation definitions is created. Each operating definition contains a catalogue of pre-defined respective work orders. The operation schedule is downloaded by the enterprise resource planning system thereby creating a set of corresponding work orders being executable by the manufacturing execution system.

Abstract: A method for controlling manufacturing processes in a plant via a MES system includes providing the MES system with product definition information, including production-related information entities containing information on how to manufacture a product, and resource-related information entities containing information about resources to be used for manufacturing that product. The MES system is provided with a single production-related information entity for manufacturing a plurality of products whose manufacturing processes share most of the process workflow and most of the resources. The single production-related entity is stored, for a non-shared resource, a label defining the non-shared resource as a generic resource. The generic resource is solved into an actual resource by creating a bind to a resource-related information entity at the creation of a production order for a specific product.

Abstract: A method for evaluating a production rule for usage as a test input process for a memory management analysis is carried out via a server process. The server process accesses at least a database of a manufacturing execution system. At least one user table is retrieved out of the database. A first number of records are retrieved for the user table. A single execution of the production rule is triggered by the server process. A second number of records are retrieved for the user table. The first number of records are compared to the second number of records and either, classifying the production rule as a suitable rule for the memory management analysis if the first and the second number of records are equal, or, classifying the production rule as an unsuitable rule for the memory management analysis if the first and the second number records are unequal.

Abstract: A method produces a product that is executed by a manufacturing execution system. A product production rule is provided and contains a plurality of product segments defining all the resources required. A customer request is received and a production request for the execution of the production according to the customer request is created. The production request copies a workflow of abstracted resources representing the workflow of production steps. The production is executed by applying the production request and asynchronously to the creation of the production request adding the resource which replaces the abstracted resource related to the first production step from the production rule to the production request thereby only copying the actually used resource into the production request and executing the respective production step on that resource. The production of the product is executed repeatedly stepwise until all abstracted resources have been replaced in the workflow.

Abstract: A manufacturing executing system (MES) contains computing devices and software tools to control machines involved in a production process. The MES is configured to realize production requirements having at least one segment requirement. The MES further contains measures for a user to define whether a segment requirement is repeatable, and a database configured to store segment requirements. The database contains for each segment requirement: a dedicated area to store each segment requirement repeatability status; a dedicated area to store at least a current value of a parameter acquired during an execution of the segment requirement and representing the result of the execution of the segment requirement; and a dedicated area to store expected values of the parameter. Finally, the MES contains a coordinator operable to communicate with the database to access the segment requirement, and operable to determine whether the execution of a segment requirement has to be repeated.

Abstract: A method and a system propagate a scaling mode in a production process controlled and executed by a manufacturing executing system (MES). The method includes the steps of providing a production request in terms of an initial quantity of a predetermined product to be produced, identifying the predetermined product by a predetermined production rule thereby dividing the production rule in a number of segment requirements that represent production actions, and defining within the segment requirements resources required to produce the required quantity. A rescaling attribute is defined and is aligned with each of the resources in a production request tree. An interface to the MES is used to update the quantity of the predetermined product to be produced and to recalculate in response to the update, the resources required to produce the updated quantity by applying a rescaling factor calculated from the initial quantity and the updated quantity.
