Motivated by the operational environment in high-tech industries, this paper examines the coordination between and when time to market and capacity marketing operations utilization are both main factors. In contrast to earlier joint lot-sizing literature which focuses on price-quantity coordination, our model captures the inter-relationship between order quantity, capacity level, and lead-time....

vendor selection decisions are complicated by the fact that various conflicting multi-objective factors must be considered in the decision making process. the problem of vendor selection becomes still more compli-cated with the inclusion of incremental discount pricing schedule. such hard combinatorial problems when solved using meta heuristics produce near optimal solutions. this paper propose...

This article develops a dynamic game model of a supply chain consisting of one manufacturer and one retailer to study the coordination mechanism and the effect of demand disruption on the coordination mechanism, where the market demand is sensitive to retail price and service. We assume that the supplier and the retailer only know the distribution of the disrupted amount after the demand disrup...

In the circumstance that unexpected events lead to information asymmetry of sales costs, supplier risk aversion and stochastic price, this paper discusses internal law using an emergency quantity discount contract coordinate supply chain. First, Conditional Value at Risk (CVaR) model under condition symmetry is constructed. addition, extended game CVaR asymmetric costs solved. After that, simul...

In this paper, we have proposed an improved genetic algorithm (GA) to solve constrained knapsack problem in fuzzy environment. Some of the objects among all the objects are associated with a discount. If at least a predetermined quantity of the object(s) (those are associated with a discount) is selected, then an amount (in $) is considered as discount. The aim of the model is to maximize the t...

Supplier selection and material procurement planning are the most important issues in supply chain management. This decision is complicated when the buyers face with discount price schemes. In real situation, each supplier may apply different methods such as different types of discount schedules and various types of payment in order to increase market share. In this situation, buyers try to sel...
