analysis of current stock of finished products pokazateleyna enterprise
LLC "Company calendar Services" positions itself as 3PLoperator, but in most cases offers a standard set of services. I propose to calculate the option, when the company's specialists would offer full outsourcing inventory management. The logistics center would have a regular customer and, accordingly, a constant amount of work, in turn, corporate customer would be possible to get cost savings - it will know at the end of the calculations.
Let the company «A» is engaged in manufacture of microwave ovens. The company has a warehouse of finished products. Guide the company dissatisfied with the department responsible for the management of our marketing stock: high logistics costs, constant complaints wholesalers, delays in production failure, etc. Therefore, management decided to transfer the management of our marketing supplies a full outsourcing. To begin with, the analysis of the cost of finished goods warehouse. Baseline data are presented in Table 3.1. Table 3.1 - Basic data on the finished product warehouse Indicators Values Volume of production of microwave ovens, 18,000 pieces per year costs for the issue of the first shipment of the wholesaler, to $ 15 Charges of storage per month, US $ 5500 Administrative administrative expenses per month, US $ 150 Number of shipments wholesaler in myasets 2 Possible disruptions of production, downtime, day 2 Average monthly wages of $ 500 Number of personnel employed in the warehouse of finished products: in the logistics department of sales, person 2 workers finished goods warehouse, persons 4 Shipment of stock occurs 2 times a month, then a year 24 shipment takes place. You can find the size of the party shipped from the formula (3.1): Q_pr = S / N_otg, (3.1) where Qpr - the size of the shipment at the plant, piece; S - output, piece; N_otg- number of shipments per year, then the size of the shipment is: Q_pr = 18000/24 = 750 pcs We find the cost of stock of finished products. A) Expenses for the execution of all orders for the year will find the formula (3.2): S_of ^ pr = N_otg * C- (PF / U), (3.2) where S_of ^ pr-cost shipping activities dollars; C- (PF / U) - the cost of registration of the first shipment, USD, they will be: S_of ^ pr = 24 * 15 = $ 360 b) Storage costs per unit of output found in formula (3.3): C- (xp / U) = pr = (Sskl + Ref) * D / S, (3.3) where C- (xp / U) ^ etc. - storage costs per unit of output, USD; Sskl - maintenance costs storage per month, USD; Ref - Other expenses for the organization of stockpiles, USD, D - period of time, months; they are: C_ (xp / U) = pr = (5500 + 150) * 12/18000 = 3.77 USD For reference we find the optimal size of the shipment by the formula Wilson (3.4): Q = √ ((2 * 〖C〗 _ (PF / U) * S) / (C- (hr / unit) * etc.)) (3.4) It is equal to: Q = √ ((2 * 15 * 18000) /3.77) = 379 pcs. From the actual size of the shipment of 750 pieces we calculated differs by almost 2 times. Apparently, the logistics enterprise considered it necessary to make the shipment of 2 times per month on the basis of cost savings when you make the shipment (the lower the number of shipments -Less processing fee). Guided by the fact that the area of the warehouse will store the size of the shipment (750sht), and on the cost of storage is not affected - they are constant 5500 dollars per month. It is worth noting that we have always hoped warehouse storage costs under the formula (3.5). However, this formula and does not take into account that the costs have permanent (own warehouse) and the number of stored products conventionally does not affect the size of storage costs.
