The Research And Application Of Production Scheduling For Machinery Manufacturing Enterprise Workshop

Machine manufacturing industry in the national economy occupies an important position as the user differentiation need and the market competition intensifies, enterprise how to order for, and how to obtain the superiority in competition, except for compliance product quality outside,timely and accurate delivery and it is very important, who can deliver the goods on time,will be the one to start with.This requires the enterprise manufacturing and synchronization time workshop supporting level rapidly improve, especially the workshop work requirements production plan must be quickly up the level.This article explores how to apply to advanced and practical scheduling approaches torealize balanced production, shorten the cycle of the parts’ processing and increase the rateof the equipment’s utility based on the research on the workshop scheduling theories andapproaches.The current status of scheduling and manufacturing management is analyzedand their disadvantages are pointed out by combining the production reality of the machining workshop of JIER Machine-Tool Group. Arebuilding scheme of workshop is brought forward based on the present equipment lay out, manufacturing types and products features, etc, in terms of design principles of groupworking unit.According to the characteristics of the plant itself, a scheduling system model isdeveloped and the overall design of the system has been made with group technology as itscore on the basis of studying scheduling optimized approaches and building group units.In the design, Petrov-Ham algorithm and heuristic rules are adopted for scheduling. The groups of classic parts----double helical gears are the objects which have verified the feasibility of the scheduling algorithm and the practicability of the scheduling system.The scheduling charts are output and the efficiency of the equipment is calculated anddisplayed.The production management efficiency and standard have been improved effectively by setting up and applying this system.This artile not only to improve the management level of machine tools industry production has an important role in promoting, and for the same type of mechanical industry also has promotion and reference.
