This paper develops a more general production-inventory model for a single-vendor–single-buyer integrated system. Unlike the hitherto existing production-inventory models for the vendor–buyer system, the present model neither requires the buyer’s unit holding cost greater than the vendor’s nor assumes the structure of shipment policy. Secondly, the model is extended to the situation with shorta...
Integrated inventory model involving quality improvement investment and advance-cash-credit payments
This paper investigates the effects of investment and inspection policies on an integrated production–inventory model involving defective items upstream advance-cash-credit payment provided by supplier. In this model, retailers offer customers a downstream credit period. Furthermore, rate item can be improved through capital co-investment supplier retailer. The objective study was to determine ...
A supply Chain (SC) with single vendor and single buyer is considered. In this research is presents lead time reduction system in an integrated inventory model for non-defective items in order to minimizing the sum of the ordering cost/setup cost, holding cost, transportation cost, production cost and lead time crashing cost of simultaneously optimizing the optimal order quantity, lead time and...
A comprehensive and integrated study of any supply chain (SC) environment is a vital requirement that can create various advantages for the SC owners. This consideration causes productive managing of the SC through its whole wide components from upstream suppliers to downstream retailers and customers. On this issue, despite many valuable studies reported in the current literature, considerabl...
Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...
In this paper we present a model and solution procedures of the Inventory Routing Problem (IRP) encountered in vending machine supply chains working under vendor-managed inventory (VMI) scheme. The new IRP model is built based on the existing Periodic Vehicle Routing Problem with Time-windows (PVRPTW). The model will be referred to as the Integrated Inventory and Periodic Vehicle Routing Proble...
abstract: an efficient supply chain system operates under a strategy to minimize costs by integrating the different functions inside the system and by meeting customer demands in time. in this paper, an integrated supply-production and distribution planning (spdp) is considered despite the fact that in most of the papers, part of the supply chain has been studied, not all parts. therefore, we d...
