Analysis: The appliance manufacturing production planning strategy - air-conditioning, compressor, r

China is a household appliances manufacturing country, China has many power plants, not only in domestic sales, many companies export products to the world, and accept foreign manufacturing orders. Manufacture of household electrical appliances have a common characteristic, that is the product of the constituent



Fitting Need through their respective branch / plant production, while some parts up to the outside

Purchase And eventually assembled into finished products.

Us with a large Air conditioning Manufacturers an example. First of all conditioned by several factory production parts, including injection molding, control



Board Production, sheet metal processing, etc. In addition,

Compressor And Motor From outsourcing. Plant needs, including market forecasts and external order two. Market forecast demand in terms of months, the demand for customer orders were given precise dates, number of export orders because of delivery schedules to consider factors that can not be delayed. Each branch is responsible for its own production scheduling, parts plant plans to produce a work plan for the final assembly factory orders, while the final assembly plant scheduled to factory production schedule for the condition.

Demand planning does not mean that production planning, marketing and manufacturing of home appliances is low season and peak season, air-conditioning in summer is the season,



TV Before the Spring Festival season may be in the coming season is between the months of peak production, peak and off-season production will be several times. During peak periods, all



Production Line Running, day and night can not meet the requirements, which may require turning off part of the off-season production line, part-time workers to leave or need fewer employees.



Excessive leave and overtime on the business and staff are very detrimental to the production should have continuous and uniform as possible. To achieve this goal, we need to demand good planning, the demand is converted to production planning, determine what time to what products should be produced, production and working time arrangements. We should also consider



Stock Costs, to avoid excessive inventory, a balance of production and inventory, business to get the maximum benefit.



To market forecasts / orders into production planning, to consider several issues:

1. Staff working hours, in the off-season to ensure the basic working hours, peak does not exceed the maximum allowable overtime.



2. The main resources (production lines, machinery and equipment) is the largest production capacity, what is the bottleneck of resources, use of bottleneck resources ahead of accessories to give priority to production.



3. Mold , Expensive Test Equipment Restrictions Although these are secondary resources, procurement costs are higher, it takes a long time, so consider these resource constraints, resources were more tight fitting long time in advance of production, for example, injection mold for a limited number of plant The parts inventory in advance of production as



4. Parts production and assembly of the match. Assembly plant to produce immediate shipment of orders, but also produce a certain stock. The parts plant that is to tie in the off-season assembly plant assembly program, but also produce some inventory of parts for assembly of the peak season.



5. Materials procurement plan according to actual production, accurate to the best days or weeks, not of months, to reduce material inventory.



Many large enterprises a wide range of products, some hundreds of species, there are thousands of many parts. Cross-sharing of parts of various products, different products will share some components of resources such as mold fixture. For such enterprises, the long-term needs into actual production tasks, coordinate branch of production planning and materials procurement outsourcing plan, is of crucial importance and complexity of a difficult task.



Work plan for the traditional enterprise model:



Present, most of the production health management plans are prepared by hand according to experience. First, plant health control assembly according to demand to see the various components of inventory, consider the branch of the parts supplier, decide what products can be produced in recent days, and notify the factory assembly of the production plan. Because the relationship between computation and detailed schedules are generally not more than a week, long-term plans can only be estimated.
