Computerized Manufacturing SystemsHistorical manufacturing and accounting management systems did not provide selective information for effective development of a production schedule or allow chain management. (6) Companies did not have the ability to measure inventory, workflow demonstrate, sweat and production efficiently or accurately. With the progression of mechanization and the revolution of the desktop computer accompanied by developing software companies are straightaway able to drill computerized manufacturing systems to record and maintain accurate data and management all aspects of the accounting and manufacturing process. (2) This paper will discuss the development of mechanisation and computerized manufacturing systems and specifically the ERP solution. Manufacturing systems were initially managed by abstract calculations or simulators designed to realize theoretical results and measure manufacturing schedules. These method actings were very fourth dimension con suming and cost effective. The line of descent of a manufacturing organization was broken down into various development phases. (1) These phases intromit the followingTable (1)Operation           The task to be performed in the manufacturing vocation shopProcessing Time      The amount of time required to process the subroutine (in most cases labels up times are in mutually beneficial of surgical operation relations and are included in processing time)Job     The set of operations that are interrelated by procedure constraints derived from technological restrictions. work     The piece of equipment (a device or a facility) capable of performing an operation. lay off Time      The time in which the job is released to the shop floor, it is the earliest time at which the first operation of the job can begin processing. collect Date      The t ime by which the last operation of the job should be completed.Completion 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 done 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 correspondent 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. One of the original programming languages, "Fortran" was use as a tool for planning departments.(5) The pl anning team would use Fortran to construct simulation models for various industries, however one of the primary uses for these models was in manufacturing and process control.
