Selecting the right suppliers for a supply chain is important as it can have great significance on the operating performance of the supply chain. The supplier selection problem can be quite complex as it usually involves numerous variables and uncertainties, which frequently come in the form of disruptions. This paper examines the existing approaches for supplier selection with focus on their advantages...
The management of supply risks has become a highly critical component of supply chain management. Supply failures effect on the supply chain can be costly and lead to significant customer delivery delays. Inventory management is an important tool to mitigate the risks arising due to these failures. But there has always been a confusion on which inventory method will be best for such situations and...
In the practical situation, market demand information is always fuzzy and expressed by fuzzy language. The existing inventory decision problems under fuzzy demand information are expanded to inventory coordination of the whole supply chain. And mathematical model of joint inventory coordination mechanism of supply chain under fuzzy demand information is proposed. A kind of transfer payment mechanism...
Under the perspective of distributor as principle, this paper set up a basic model to study the principle-agent problem between distributor and manufactures in a supply chain with the condition of stochastic demand and asymmetric information. It is fund that asymmetric information damages the distributor's expected profit, but by method of changing some specific supply chain contract parameters, the...
Efficient management of inventory in supply chains is critical to the profitable operation of modern enterprises. The supply/demand networks characteristic of discrete-parts industries represent highly stochastic, nonlinear, and constrained dynamical systems whose study merits a control-oriented approach. Minimum variance control (MVC) strategy is applied to solve the dynamic optimization problems...
The option contract is one of the effective financial instruments for avoiding risk. There always exists the risk in supply chain especially when facing uncertain or random demand. By introducing the real option into a two-stage supply chain, the part of the buyer risk due to demand uncertainty can be shifted to the supplier, and the supplier, in turn, is recovered by the additional revenue obtained...
An optimizing model for studying production- inventory policy with service level constraints is proposed. To realize the integrative decision of service level and production point, the service level in a supply chain is defined as the probability of satisfying product demand in each planning period. Inventory variation under stochastic demand is analyzed, and the average inventory in each planning...
With and without vendor managed inventory (VMI), two inventory cost models in the condition of one vendor and multiple retailers in e-commerce have been presented. Then according to the status of VMI implementation, the optimized analysis about inventory cost is analyzed by using genetic algorithm.
Competitive supply chains compose a complex network with multi-tier structure, where members at same tier compete in a Nash game. Under the assumption that the consumers are stochastic multicriteria decision-makers, who firstly choose which retailer they transact with, and then make their consumption decisions with deficient information, this paper use nested logit model to character the consumerspsila...
Taking the retailerpsilas default in supply chain for example, in this paper, using the theory of credit default swap, the writer intends to make a research on the shift of default risk in supply chain. On the condition of insured interest rate and recovery rate, a supposition is made that the default rate of supply chain depends on the doubly stochastic Poisson default process, and then a model of...
Considering resources constraints of supply chain environment, a problem of products optimal decision under demand uncertainty was studied in this paper. Putting every component of supply chain such as suppliers, manufacturing plant, distribution centers and customers into an identical decision system, an integrated optimal stochastic chance constraint programming model with objective of maximum profit...
