Epson (shanghai) Information Products Limited Inventory Management Information System's Development

As a composite system, logistics has become one of the basic function of an enterprise. As the reserve of a series of logistics operation, inventory is the most important sector of the whole logistics system. Because it not only affects the efficiency of whole logistics chain but also is the significant key cost for an enterprise. Therefore, an investigation is made on the inventory management of EPSON (Shanghai) Information Equipment Co., Ltd. ,where I am now employed in. By mean of further exploitation and investigation on the method of inventory, we will improve the unreasonable inventory situation and optimize inventory structure, so that we can set up a better and continuous enterprise developing environment The main content of this thesis is the inventory management of the printer parts which is necessary for the after service system. The core discussion subject in this thesis is ?Forecast?梐 key factor on inventory management. In ESIE, we decide a series of logistics operation through forecast. Apparently, an inaccurate forecast to sales and purchase will bring trouble to the supply of service parts, so as to lower the end users?satisfactory level. It is necessary to carry on classifying control on a wide variety of stocks in warehouse. Therefore, this thesis focus on classifying control on inventory, which is carried on with two kinds of forecast. We will design and exploit a system for forecast and inventory control. Because the original method used by ESIE has a few of shortcomings in classifying a wide variety of parts?stock and in referring to historical information. Hereby, through this thesis we try to set up a new forecast system operated by the computer. In prerequisite for setting the value of RANK?to represent turnover situation of each part, .the forecast for each part are carried on, thus to let all the forecast and inventory management base on statistics theory and accurate data source, and make the forecast result much more accurate, reliable and C ) perspective In this thesis, an original forecast method and calculating formulas is described. Meanwhile a designing new forecast system is set up, giving a minute description for each model and its function of the system. It is of great importance to set up some key parameters, such as turnover rate of each part, Rank value, minimum inventory, inventory level, maximum inventory and etc. Primary algorithm and flow charts have been designed. All the formulas in algorithm have proper theoretical principles. Some predicated results and inventory reports (including warning report) are simulated in terms of the designed one, and these results are compared with the results obtained from original 4 predictor method. In the meantime, caution signal of each part can also be obtained at any time from the new system, thus sales and purchase can be conducted in time, finally the efficiency of the logistics system can be increased. Following functions of the new system are shown in this thesis. It can store historical data and quantitatively predict gross sales and purchase in the current month and the future three months on the basis of historical data. It can give forecast of sales and purchase effectively and accuratel...
