Research On The Task Unit Method Based On Manufacturing Costs

The cost and profits is always being the focus of the companies'concern.And they investigate tirelessly the topic that how to obtain larger profits with the smaller cost for ever. It is very important that if the arrangement of the working-stations to an assembling stream line. The amount of the working-stations decides the size of the workload of each working-station directly, influencing the cycle time of the assembling stream line thus. And the cycle time is relative to the speed of the profits achievement. This text combines cost checking technique, investigating to design of the working-stations and the cycle time of an assembling stream line. Put forward "The Working Unit Method" to design and balance the stream line. It is helpful for a company to achieve the biggest profits.1.IntroductionThe maximized profits is the target that the business enterprise pursues forever, and the minimum cost is also the business enterprise's delving topic. But there is reverse between them.The biggese profits always needs one fixed amount of cost. Looking for a balance point here would give the business enterprise a best choice.Today lean production have already become popular in the world. The companies vie with each other with the compression of costs to promote the profits space. The lean production puts forward compressing costs and reducing wastes as much as possible. This text discusses how to make an assembling stream line get the biggest profits with the cost theories.2.Manufacturing cost of the productionThis chapter introduces some related theories about the product cost checking.Specifies the related research on the method of cost checking in the world these years. Give the classifying method of the product cost, modeling method and checking method etc..3.Modeling of the costs of the assembling stream lineThe textual research target is the design on the assembling stream line in one company. Around the production of the assembling stream line, this chapter choose the stock cost, the energy cost, the logistics cost,the labor cost as the main structures of the whole production cost.Combining the cost theories, this chapter sets up the mathematics models about the related cost of the assembling stream line. With the formulae, the companies can analyse the cost of the assembling stream line in time, and respond the needs of the market and production in time.It is helpful to lower the management risk and increase the profits for the companies. It should be mentioned that the formulae given in this chapter have a certain representative to the costs of the companies, but without catholicity.The companies have differences in layer constitutes, the management method, the existing environment and the technical level, so the formulae must be modified as the actual circumstance before using. Only when related part in the formulae have been modified correctly, the checked cost would be nearer to the fact.4,Task unit methodThe task unit method is a kind of designing method on the working-station of the assembling stream line, which is put forward by the writer. The traditional designing method always focus to the assembled object, namely the accessories. Assemblages of one or more accessories are assigned into a working-station. This kind of method factitiously give a lowest limit to the cycle time of the stream line. If a time to assemble a certain accessory is too long to others, it would surely cause a big cycle time or the maladjustment of the equilibrium, or any other bad conditions to the stream line.The task unit method is to divide all the assembling steps into many independent task units which can exist steadily on the stream line without any outside forces, and ascertain the concrete work of a working-station by the combinations of the task units. The assemblage of one accessory can be constituted by one or several task units.While designing the stream line, it can be done in one or several working-station. Each task unit has its standard working time. Add the standard working times of all the task units in one working-station, and it would be the cycle time of the stream line. With the task unit method, it would be more flexible when designing a stream line, and also give a stream line a better balance and harmony.This chapter gives a detailed description to the task unit method. Give the definition of the task unit method , the classification and the processes when applying the task unit method.5,The design of the assembling stream line in a car company First of all, writer modified the formulae on the costs of chapter 3 ,make it match the actual circumstance of the stream line. And then analysis the works of the working-stations with the task unit method. Combined with the formulae in chapter 3 , account the profits for a year and choose the best profit to the assembling stream line, and give the actual condition of every working-station of the stream line. The result prove that combine of the costs checking theories and the task unit method to design the stream line can raise a company's profits to a large extent. It has important meaning to the existence and development of a company.The modeling of the costs and the task unit method are the innovations of this text. While using alone, the modelings are helpful to hold its actual performance; the task unit method makes it easy to balance the stream line. And it can provide a easy route to design an assembling stream line when use both them together.
