This paper presents a multi-periodic, multi-echelon blood supply chain network consisting of blood donors, mobile collection units, local blood centers, main blood centers and demand points in which the local and main blood centers are subject to random failure in dispatching blood products to demand points. The problem has two objectives including minimization of the total chain costs and maxi...

disasters can cause many casualties and considerable destruction mainly because of ineffective preventive measures, incomplete preparedness, and weak relief logistics systems. after catastrophic events happen, quick and effective response is of great importance, so as to having an efficient logistic plan for distributing needed relief commodities efficiently and fairly among affected people. in...

in this paper, a hybrid method for limited resource allocation and leveling in complex multi-stage, multi-product and multi-period production planning problems with aim of lot-size determination and total cost minimization has been proposed. this problem consists of multiple products with sequential production processes that are produced in different periods to meet the customers demand. by det...

The multi-point values of an appropriate smoothing parameter of HP-filter algorithm for midterm electricity load demand (MELD) forecasting are proposed. The case study employs the data based on the organization of the Electricity Generating Authority of Thailand (EGAT). The research shows the growth at rate of weather and economic factors influencing to the electricity demand. The main focus of...

AIM To assess the economic impact of increased nursing hours of care on health outcomes in adult teaching hospitals in Perth, Western Australia. BACKGROUND Advancing technology and increased availability of treatment interventions are increasing demand for health care while the downturn in world economies has increased demand for greater efficiency. Nurse managers must balance nurse staffing ...

The prevalence of commercial activities whose profit and cost are correlated with weather risk makes weather derivatives valuable financial instruments that enable hedging of price or volumetric (quantity) risk in many industries. This paper proposes a multi-period equilibrium pricing model for weather derivative. In our stylized economy representative agents of weather-sensitive industries opt...

We consider the problem of allocating multiple heterogeneous resources geographically and over time to meet demands that require some subset available resource types simultaneously at a specified time, location, duration. The objective is maximize total reward accrued from meeting (a of) demands. model this as an integer program, show it NP-hard, analyze complexity various special cases. introd...

In the last decade some countries decided to undertake a deregulation process of the electricity sector in order to bring competition to the previously monopolistic market. In all those countries electricity is now a traded commodity and its price is determined according to the rule of supply and demand. The empirical analysis reveals that market prices are variable and unpredictable with jumps...

In this paper, a discount model is proposed to coordinate pricing and ordering decisions in a two-echelon supply chain (SC). Demand is stochastic and price sensitive while lead times are fixed. Decentralized decision making where downstream decides on selling price and order size is investigated. Then, joint pricing and ordering decisions are extracted where both members act as a single entity ...
