Solving the competitive facility location problem considering the reactions of competitor with a hybrid algorithm including Tabu Search and exact method
(Islamic Azad University, South Tehran Branch, 2018-03-01)In this paper, a leader–follower competitive facility location problem considering the reactions of the competitors is studied. A model for locating new facilities and determining levels of quality for the facilities of ...

Analysis of interactions among barriers in project risk management
(Islamic Azad University, South Tehran Branch, 2018-03-01)In the context of the scope, time, cost, and quality constraints, failure is not uncommon in project management. While small projects have 70% chances of success, large projects virtually have no chance of meeting the ...

Phase-I monitoring of standard deviations in multistage linear profiles
(Islamic Azad University, South Tehran Branch, 2018-03-01)In most modern manufacturing systems, products are often the output of some multistage processes. In these processes, the stages are dependent on each other, where the output quality of each stage depends also on the output ...

Multiple utility constrained multi-objective programs using Bayesian theory
(Islamic Azad University, South Tehran Branch, 2018-03-01)A utility function is an important tool for representing a DM's preference. We adjoin utility functions to multi-objective optimization problems. In current studies, usually one utility function is used for each objective ...

Availability analysis of mechanical systems with condition-based maintenance using semi-Markov and evaluation of optimal condition monitoring interval
(Islamic Azad University, South Tehran Branch, 2018-03-01)Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, ...

Integrated model for pricing, delivery time setting, and scheduling in make-to-order environments
(Islamic Azad University, South Tehran Branch, 2018-03-01)Usually, in make-to-order environments which work only in response to the customer's orders, manufacturers for maximizing the profits should offer the best price and delivery time for an order considering the existing ...

Optimal replenishment and credit policy in supply chain inventory model under two levels of trade credit with time- and credit-sensitive demand involving default risk
(Islamic Azad University, South Tehran Branch, 2018-03-01)Traditional supply chain inventory modes with trade credit usually only assumed that the up-stream suppliers offered the down-stream retailers a fixed credit period. However, in practice the retailers will also provide a ...

Solving the flexible job shop problem by hybrid metaheuristics-based multiagent model
(Islamic Azad University, South Tehran Branch, 2018-03-01)The flexible job shop scheduling problem (FJSP) is a generalization of the classical job shop scheduling problem that allows to process operations on one machine out of a set of alternative machines. The FJSP is an NP-hard ...
