Incorporated into PROSPAC's design is the capability to exchange data with other computer systems. Information exchanged between PROSPAC and another system is accomplished with the simplest of interface files. These files are "ASCII flat files", perhaps the most fundamental of file types. Such files can be created or modified in DOS's edit application, Window's NotePad and WordPad, Unix's vi or emacs editors, Linux's vi editor, and most any other basic text editor. PROSPAC features the acceptance of import interface files in three major areas:
TIMECARDS. Even though PROSPAC has a fully featured Employee Timekeeping system (PROSPAC2 module) of its own, it also accepts timecards in the form of an import interface file from a variety of other timekeeping systems. PROSPAC's scheduler requires the information from direct labor timecards, using them as feedback of what actually happened on the shop floor, as a starting point for computing new production schedules. SHOP WORK ORDERS. While PROSPAC has a robust Shop Work Order Management system (PROSPAC1 module), it also accepts work order releases, work order variable changes, work order holds, and work order deletes in the form of an import interface file. The minimum work order variables that PROSPAC requires are: shop work order number, part number, shop work order release date, shop work order due date, and shop work order quantity. There are several other shop work order variables such as priority, work order class, material release code, and concatenation code that could be sent through the interface, but these can also be set by pre-determined defaults. ROUTINGS. Notwithstanding PROSPAC's very extensive Manufacturing Engineering system (PROSPAC3 module), import interface files, each containing the routing data for one part number, convey the minimum routing data required by PROSPAC's scheduler: part number, and for each operation: operation number, setup time standard, unit run time or production rate standard, and machine name or number. Much of the remaining routing data, if not available from the originating computer, can usually be set by default: manufacturing engineering revision code, operation chain indices, operation type (master, write-in, rework), operation concatenation enablement, operation overlap enablement, step yield percent, attention percent, dicing factor, tool code(s), FTBO-flow time between operations, and LTBO-lead time before operation. Export interface files are used to transmit almost any hardcopy report, or the tabularized equivalent thereof (i.e., a report minus its page headers and captions), available in the PROSPAC system. Unix's and Linux's awk, sed, and sort commands can be used in a shell script to quickly convert almost any tabular hardcopy report from the PROSPAC system into an "ASCII" export data file for use in other systems. |
