| Nowadays,the market is keeping constantly changing,people's quality of life is keeping be improved,and consumers' individuation are keeping more and more complex,which leads to the market is being more and more difficult to be forecasted.Advanced technology such as the Internet,information technology,and globalization promotes the society development rapidly,but also makes the market competitive pressures increased correspondingly.At the same time,product cycles are being shortening,market uncertainty are being increased.All in all,under this condition,managers of supply chain need to improve managing skill and take reasonable measures to face the challenge.When the market situation is poor,a sharp decline in demand,resulting in oversupply of finished products,an increase of inventories,and increase of storage costs.Storage costs tying up a lot of working capital,leading to cash flow circulation slow,which affect business survival seriously.So,this article's production optimization problem is studied under oversupply market due to falling demand basing on the perspective of the supply chain.Firstly,he total supply chain cost structure is analyzed and established on the consideration of tying up capital costs which measured with inventory financing model.Through the establishment and analysis of the total cost model,found that supply chain objective is to minimize the total cost.Secondly,in pursuit of minimizing expected total cost of supply chain as the objective,the production optimization goal-programming model is established by taking advantage of unproductive rate.Through solving and analysis,the definition and the economic signification of supply chain unproductive rate decision boundary curve are given.Lastly,on this basis of work,the unproductive cost efficient is introduced as the decision criterion to determine the optimal production plan.An example is given to test,simulate and illustrate the above model through computer software MATLAB. |
