In this paper, four routing protocols AODV (Adhoc On demand distance vector), ZRP (Zone routing protocol), DSR (Dynamic Source Routing), and DYMO (Dynamic Manet On Demand), are analyzed and compared by using QualNet simulator on the basis of performance metrics such as Throughput, Average End-to-End Delay, Average Jitter, Total Packets Received, Packet Delivery Ratio, Energy Consumption in tran...

In this paper, we present a genetic algorithm (GA) for optimization of a multi-mode resource constrained time cost trade off (MRCTCT) problem. The proposed GA, each activity has several operational modes and each mode identifies a possible executive time and cost of the activity. Beyond earlier studies on time-cost trade-off problem, in MRCTCT problem, resource requirements of each execution mo...

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...

Abstract Ring resonator is an essential element in silicon integrated circuit, it widely used as filter, wavelength multiplexer and switch single-mode operation regime. As the rapid development of mode division multiplexing (MDM) technique, ring that can process multi-mode signals simultaneously uniformly highly desired. However, severe modal dispersion makes identical transmission for differen...

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...

This paper presents a multi-mode resource-constrained project scheduling problem (MRCPSP) with maximizing the net present value (NPV) form the project contractor’s point of view. Positive and negative cash flows are considered in this model. Furthermore, to make the model close to the real situations, four different models for positive cash flows are considered. Two meta-heuristics, called simu...
