MergedAutomobile Maintenance Part Delivery Problem Using an Improved Artificial Bee Colony Algorithm
(Sharif University of Technology, 20150601)The merged automobile maintenance part delivery problem will attract interests from the merged company due to the reduced delivery cost by collaborative delivery among several automobile part depots. Since the delivery ...

Comparing four ordering policies in a lost sales inventory model with Poisson demand and zero ordering cost
(Sharif University of Technology, 20150601)In this paper, we compare four ordering policies in a lost sales inventory model with zero ordering cost, constant lead time, and Poisson demand process. These ordering policies are 1) base stock policy, 2) full delay ...

Interrelating physical and financial flows in a biobjective closedloop supply chain network problem with uncertainty
(Sharif University of Technology, 20150601)This paper presents a biobjective logistic design problem integrating the financial and physical flows of a closedloop supply chain in which the uncertainty of demand and the return rate described by a finite set of ...

Improved estimation of finite population median under twophase sampling when using two auxiliary variables
(Sharif University of Technology, 20150601)We propose an efficient estimator for population median under twophase sampling when using two auxiliary variables on the lines of Diana [Diana, G. “A class of estimators of the population mean in stratified random ...

Robust economicstatistical design of multivariate exponentially weighted moving average control chart under uncertainty with intervaldata
(Sharif University of Technology, 20150601)The cost parameters in economicstatistical models of control charts are usually assumed to be deterministic in the literature. Considering uncertainty in the cost parameters of control charts is very common in application. ...

An empirical comparison of simulated annealing and iterated local search for the hierarchical single allocation hub median location problem
(Sharif University of Technology, 20150601)Hub location problem (HLP) has been an attractive area of research for more than four decades. A recently proposed problem in the area of hub location is the hierarchical singleallocation hub median problem (SAHMP) which ...
