1. An Interdiction Median Model for Hierarchical Capacitated Facilities

A. Forghani; F. Dehghanian

Volume 3, Issue 1 , Spring 2014, Pages 1-10

Abstract
  In this paper a partial interdiction problem on a capacitated hierarchical system is studied. We consider an attacker who can interdict facilities at different levels and each interdiction level causes a specified reduction in the capacity of a facility depending upon its service level in the hierarchy. ...  Read More

2. Comprehensive Method to Determine Real Option Utilizing Probability Distribution

M. Modarres Yazdi; M. Shafiei; S.M. Sahihi Oskooyi

Volume 3, Issue 1 , Spring 2014, Pages 11-25

Abstract
  Data envelopment analysis (DEA) is a non-parametric analytical methodology widely used in efficiency measurement of decision making units (DMUs). Conventionally, after identifying the efficient frontier, each DMU is compared to this frontier and classified as efficient or inefficient. This thesis introduces ...  Read More

3. A New Estimator Based on Likelihood Function for Drift Time of Change in Poisson Rate Parameter

R. Hosseiny; V. Amirzadeh; M. A. Yaghoobi

Volume 3, Issue 1 , Spring 2014, Pages 26-38

Abstract
  Although a control chart can signal an out-of-control state in a process, but it does not always indicate when the process change has begun. Identifying the real time of the change in the process, called the change point, is very important for eliminating the source(s) of the change and assists process ...  Read More

4. Robust Design of Maintenance Scheduling Considering Engineering Insurance Using Genetic Algorithm

S. Molaei; K.M. Cyrus

Volume 3, Issue 1 , Spring 2014, Pages 39-48

Abstract
  Preventive maintenance is a broad term that encompasses a set of activities aimed at improving the overall reliability and availability of a system. Designers of the preventive maintenance schedules attempt to minimize the overall cost of system operation. There is no substitute for perfection in maintenance ...  Read More

5. Presenting a New Approach toward Locating Optimal Decoupling Point in Supply Chains

M. Rabbani; H. Yousefnejad; H. Rafiei

Volume 3, Issue 1 , Spring 2014, Pages 49-54

Abstract
  This article attempts to cope with one of the most vital strategic decisions in the supply chain design in terms of manufacturing context. The issues of finding the best position of Customer Order Decoupling Point (CODP) in a production line have been taken into consideration by many researchers in recent ...  Read More
