5 物料在供应商间的采购分配
5.1 采购分配的线性规划模型
在实际中,企业采购需要遵循半数比例原则和供应源数量控制原则[7]。
从供应商风险衡量的角度,半数比例原则要求购买数量不能超过供应商产能的50%。如果仅由一家供应商负责100%的供货和100%成本分摊,则采购商面临的潜在风险较大。
供应源数量控制原则是指实际供货的供应商数量不应该太多,同类物料的供应商数量最好保持在2~3家,有主次供应商之分(依次分为1级、2级、3级),这样可以降低管理成本和提高管理效果,保证供应的稳定性。
当要实施替补选择时,我们要解决怎样将一定数量的订购任务由多个供应商来供货,物料i在几个供应商之间怎样分配的问题。将经过AHP选择出来的几个供应商的供货量作为决策变量,利用线性规划(LP)的方法来求解。

5 suppliers in the procurement and distribution of materials between the linear programming model
5.1
procurement allocation in practice, corporate purchasing half of the principle of proportionality and the need to follow the supply quantity control principle [7].
From the perspective of supplier risk measure, half of the principle of proportionality requires the purchase can not exceed 50% of the number of suppliers of capacity. If only one supplier is responsible for the delivery of 100% and 100% of the cost-sharing, the greater the potential risk of sourcing providers face.
Supply quantity control principle is the actual number of suppliers to supply should not be too much, the number of suppliers of similar material is best kept at 2 to 3, there are primary and secondary suppliers of (turn divided into one, two stage 3),This can reduce management costs and improve management effectiveness, to ensure stability of supply.
Choice when you want to implement the bench, we have to solve how to order a certain number of tasks by a number of suppliers to supply, material i between several suppliers how to allocate the problem. After ahp will choose out of several suppliers of shipments as decision variables, the use of linear programming (lp) method to solve it.

5 material suppliers procurement allocation
5.1 procurement allocation model of linear programming. In practice, the enterprise procurement needs to follow the half proportion principle and supply quantity control principle of [7].
measured from the supplier risk perspective, half the proportion principle requires the purchase quantity cannot surpass the capacity of suppliers 50%. If 100% is owned by a supplier and a 100% cost share, then buyers face greater potential risk.
supply quantity control principle refers to the number of actual delivery suppliers should not be too much, the number of suppliers of similar material is best kept at 2~3, a supplier of primary and secondary (divided into level 1, level 2, level 3),This can reduce the management cost and improve management effectiveness, ensure the stability of the supply of. When implementing the bench when the choice, we address how a certain number of tasks to be ordered by multiple suppliers, how material I distribution in several suppliers problem. Supply of several suppliers after AHP selected as the decision variables, using linear programming (LP) method to solve the.

5 raw materials suppliers of procurement allocation
5.1 allocation between the linear programming model of
in practice, supplier purchasing half of the need to follow the principles of proportionality and containment principles [7].
From the perspective of supplier risk measure, half of the principle of proportionality requires the purchase of vendor number capacity of 50%. If only one vendor is responsible for the third of the deliveries and 100% cost sharing, potential risk to the buyers.
Source volume control means the actual number of suppliers of supply should not be too much similar material is best to keep the number of vendors at the 2~3 House, a distinction between primary and secondary suppliers (in turn are divided into level 1, level 2, level 3),This would reduce administrative costs and improve the effectiveness of management, ensuring stability of supply.
When implementing alternate choices, we need to figure out how to order your tasks by multiple vendors to supply a certain number of item I in the question of how to allocate among several vendors. Pass an AHP to select several supplier shipments as a decision variable, using linear programming (LP) method to solve it.
