3.4.2 Major UML PackagesTheCMSDInformationModel’sUMLrepresentation has been organized using UMLpackages, see Figure 1. UML packages, depicted asfile folders, are UML constructs that can be used toorganize model elements into groups.UMLpackages make UML diagrams simpler and easierto read. A brief description of each package ispresented below.The CMSD Information Model consists of thefollowing major UML packages:• CMSD packageThe CMSD package is the top-levelpackage of the CMSDIM. It provides agrouping and model managementfunction for all of the other packagesdefined in the architecture. All of theother packages are either directly orindirectly nested within this package.• Support packageThe Support package provides a groupingand model management function for foursub-packages.These sub-packagescontain definitions for basic data typesand data elements for variousapplications. Examples of these dataelements include commonly-used datastructures and referenced data elements.• Resource Information packageThe Resource Information packagecontains definitions for the resources(employees, machines, stations, etc.)used in manufacturing, the skillsassociated with human resources, andsetup information required for theefficient operation of machine resources.• Production Planning packageThis package contains definitions forinformation necessary to plan foreffectivemanufacturing operations. Itcontains definitions for organizations,shifts, processplans, and operation andmaintenance definitions.• Production Operations packageThis package contains definitions forinformation about the state manufacturingoperations that are either currently takingplace or that have been already plannedfor. This includes information aboutorders for the manufacture of parts, jobsthatstate which manufacturing operationwill take place using which resources,andschedules showing job or orderinformation for given resources over aspecific time period.• Part Information packageThis package contains information aboutthe products that will be produced as aresult of the manufacturing process. Billof materials information is also definedin this package.
