چکیده
This paper addresses the long-standing stochastic single-vendor, multi-manufacturer inventory control problem, using simulation optimization. It is assumed that Manufacturers producing similar goods experience very high random demand; hence, safety stock of raw materials held in reserve their warehouses. The vendor supplying this material (principal ingredients) as a policy restricts shipments to multiples full truck load. Thus, it necessary take replenishment decision and coordinate delivery among these manufacturers. To solve we modeled single vendor, manufacturer version problem (AlDurgam et al., 2017) optimization techniques, which was validated numerically parameters results from AlDurgam al. (2017). model modified systematically relax assumption under two distribution policies namely, joint reorder point managed inventory. These were evidently with stringent conditions literature. A numerical example provided compare performances proposed policies, VMI found performed better terms financial savings. Lastly, investigate robustness famous continuous review (Q, R) widely used mathematical modeling against common cycle assumption. coefficient variation thus suggested judgment criterion when embrace ahead other techniques.

Vendor Managed Inventory of a Single-vendor Multiple-retailer Single-warehouse Supply Chain under Stochastic Demands
In this study, a vendor-managed inventory model is developed for a single-vendor multiple-retailer single-warehouse (SV-MR-SV) supply chain problem based on the economic order quantity in which demands are stochastic and follow a uniform probability distribution. In order to reduce holding costs and to help balanced on-hand inventory cost between the vendor and the retailers, it is assumed that...

In this paper, a chance-constraint joint single vendor, single buyer supply chain problem with stochastic demand and fuzzy lead-time is investigated. The lead-time is lot size dependent; and delay times such as moving, waiting and setting time are fuzzy. The shortage costs result from backorder and/or lost sale, and the uncertain demand follows a uniform distribution. The buyer’s cost function ...

In this paper, a multi-product multi-chance constraint joint single-vendor multi-buyers inventory problem is considered in which the demand follows a uniform distribution, the lead-time is assumed to vary linearly with respect to the lot size, and the shortage in combination of backorder and lost-sale is assumed. Furthermore, the orders are placed in multiple of packets, there is a limited spac...
متن کاملVendor Managed Inventory of a Supply Chain under Stochastic Demands
In this research, an integrated inventory problem is formulated for a single-vendor multiple-retailer supply chain that works according to the vendor managed inventory policy. The model is derived based on the economic order quantity in which shortages with penalty costs at the retailers` level is permitted. As predicting customer demand is the most important problem in inventory systems and th...
