Computerized Manufacturing SystemsHistorical manufacturing and accounting management systems did not provide data for effective development of a production schedule or supply chain management. (6) Companies did not have the ability to flier inventory, workflow process, labor and production efficiently or accurately. With the progression of automation and the revolution of the background knowledge computer accompanied by developing software companies are now able to use computerized manufacturing systems to record and maintain accurate data and management exclusively aspects of the accounting and manufacturing process. (2) This paper will discuss the development of automation and computerized manufacturing systems and specifically the ERP solution. Manufacturing systems were initially managed by abstract calculations or simulators designed to produce theoretical results and measure manufacturing schedules. These methods were very time consuming and cost effective. The job of a manu facturing organization was broken down into various development phases. (1) These phases include the followingTable (1) transaction           The task to be performed in the manufacturing job shopProcessing Time      The amount of time required to process the operation (in most cases sets up multiplication are independent of operation relations and are included in processing time)Job     The set of operations that are interrelated by social function constraints derived from technological restrictions.Machine     The piece of equipment (a device or a facility) capable of performing an operation.Release Time      The time in which the job is released to the shop floor, it is the so wholenessst time at which the first operation of the job can begin processing.Due Date      The time by which the last operation of the job should be completed.Comple tion Time      The time at which processing of the last operation of the job is complete.Schedule     Specification of execution of each operation on a particular machine at a specific time. A feasible schedule is a schedule that observes all problem constraints.These phases would usually be do manually and line managers would measure the process.(1) These measurements would be dependent on variable for example, sick time, employee production and employee motivation.(1) Although these steps are similar today these variables have been greatly removed from the manufacturing process through automation and more efficient production data and scheduling tools available.(1)Another method for developing manufacturing schedules was through the use of simulators. sensation of the original programming languages, "Fortran" was used as a tool for planning departments.(5) The planning team would use Fortran to construct simulation models for vario us industries, however one of the primary uses for these models was in manufacturing and process control.
