Economic load dispatch is a non linear optimization problem which is of great importance in power systems . While analytical methods suffer from slow conversion and curse of dimensionality particle swarm optimization can be an efficient alternative to solve large scale non linear optimization problem.A lot of advancements have been done to modify this algorithm. This paper presents an overview ...

The rapidly growing biofuel industry poses considerable challenges to its supply chain network design and operations. In this chapter, we introduce key characteristics of the biofuel supply chain that comprises of feedstock production, biomass logistics, biofuel production and distribution. We then discuss the recent literature on biofuel supply chain models. Using an illustrative biofuel suppl...

Trade credit is a well established promotional tool in the present competitive world and its impact on demand cannot be ignored. Businesses often use trade credit to increase their market share and, in turn, the profit. Undoubtedly, trade credit plays a great role in increasing the demand but it also involves a great risk of nonpayment. In order to reduce the risk of non-payment, businessman at...

the major problem of wind turbines is the great variability of wind power production. the dynamic change of the wind speed returns the quantity of the power injected to networks. therefore, wind–thermal generation scheduling problem plays a key role to implement clean power producers in a competitive environment. in deregulated power systems, the scheduling problem has various objectives than i...

In real supply chain environments, the discontinuous multidelivery policy is often used when finished products need to be transported to retailers or customers outside the production units. To address this real-life production-shipment situation, this study extends recent work using an economic production quantity- (EPQ-) based inventory model with a continuous inventory issuing policy, defecti...

The paper compares the expected performance of a Vendor Managed Inventory (VMI) supply chain with a traditional “serially-linked” supply chain. The emphasis of this investigation is the impact these two alternative structures have on the “Bullwhip Effect” generated in the supply chain. We pay particular attention to the manufacturer’s production ordering activities via a simulation model based ...

We consider a model for a serial supply chain in which production, inventory, and transportation decisions are integrated, in the presence of production capacities and for different transportation cost functions. The model we study is a generalization of the traditional single-item economic lot-sizing model, adding stationary production capacities at the manufacturer, as well as multiple interm...

In this paper, a single-vendor, single-buyer supply chain for fixed lifetime product is considered. We propose models to analyze the benefit of coordinating supply chain through quantity discount strategy. Under the proposed strategy, the buyer is requested to alter his current order size such that the vendor can benefit from lower costs, and quantity discount is offered by the vendor to compen...

In recent years, the quality risks in supply chain are frequently encountered by Chinese's manufacturing enterprises, the aim of the paper is to present a manufacturer perspective methodology of forecasting quality risks in supply chain. To do it, firstly, we innovatively propose achieving factors of quality risks by the house of quality of quality function deployment. Secondly, an optimal sele...

Vendor-managed inventory (VMI) is a supply-chain initiative where the supplier is authorized to manage inventories of agreed-upon stock-keeping units at retail locations. The benefits of VMI are well recognized by successful retail businesses such as Wal-Mart. In VMI, distortion of demand information (known as bullwhip effect) transferred from the downstream supply-chain member (e.g., retailer)...
