[ 1 ] - Implementing Bounded Linear Programming and Analytical Network Process Fuzzy Models to Motivate Employees: a Case Study
In this research, the factors affectinguniversity employees’ motivation and productivity are identified and classified in seven groups; the impact of each motivation factor on the productivity is presented by ANP fuzzy model.Eight universities in Iran were analyzed in this research work. The aim of this study is to explore the productivity of employees. This paper attempts to give new insights ...
[ 2 ] - Development of a novel lot sizing model with variable lead time in supply chain environment
Supply chain management (SCM) addresses the management of materials and information across the entire chain from suppliers to producers, distributors, retailers, and customer. The theory of supply chain management suggests that lead time reduction is a pioneer to the use of market mediation to reduce transaction uncertainty in the chain, which can be conceptualized as the primary goal of supply...
[ 3 ] - A Novel Innovative Design Improvement using Value Engineering Technique: a Case Study
Manufacturers around the globe are competing for the identification of innovative value propositions to survive in the competitive and complex market. This paper is intended to investigate implementation of Value Engineering (VE) technique into the product design concept for necessary changes in design of the humidifier system in order to lower unnecessary costs and to increase quality of the p...
[ 4 ] - Application of Particle Swarm Optimization and Genetic Algorithm Techniques to Solve Bi-level Congestion Pricing Problems
The solutions used to solve bi-level congestion pricing problems are usually based on heuristic network optimization methods which may not be able to find the best solution for these type of problems. The application of meta-heuristic methods can be seen as viable alternative solutions but so far, it has not received enough attention by researchers in this field. Therefore, the objective of thi...
[ 5 ] - An exact Method for Stochastic Maximal Covering Problem of Preventive Healthcare Facilities
Effective preventive healthcare services have a significant role in reducing fatality and medical expenses in all human societies and the level of accessibility of customers to these services can be considered as a measure of their efficiency and effectiveness. The main purpose of this paper is to develop a service network design model of preventive healthcare facilities with the principal obje...
[ 6 ] - مکان‌یابی مراکز خدماتی با هدف بیشینه‌سازی سهم رقابتی در یک زنجیرۀ تأمین بسته
این مقاله به مدل‌سازی و حل مسئلة مکان‌یابی مراکز خدماتی و تعیین مراکز جمع‌آوری کالاها در زنجیرة تأمین حلقة بسته پرداخته است. مقالات موجود در ادبیات موضوع، معمولاً یکی از رویکردهای افزایش سود یا افزایش سهم بازار را مدنظر قرار داده‌اند، اما با توجه به پژوهش حاضر، این دو هدف ممکن است در تعارض با یکدیگر باشند. در این مقاله، هر دو رویکرد افزایش سهم بازار و افزایش سودآوری به‌صورت هم‌زمان اعمال شده‌اند...
[ 7 ] - Ranking Locations Based on Hydrogen Production from Geothermal in Iran Using the Fuzzy Moora Hybrid Approach and Expanded Entropy Weighting Method
The present study aimed at ranking and selecting the superior geothermal project for hydrogen production in 14 provinces of Iran using a multi-objective optimization fuzzy hybrid approach through analyzing the ratio (fuzzy Moora) and expanded entropy weighting method. In this research, the extended entropy weighing method and the Fuzzy-Moora approach were utilized to weigh the criteria and proj...
[ 8 ] - The Ranking of Southern Ports and Islands of Iran for Seawater Desalination Plants Using ELECTRE III Method
The energy insecurity, environmental pollution, climate change and even reduced rainfall in some countries are prime examples of consequences of the world’s excessive reliance on fossil fuels. This study suggests that in some southern islands and coastal areas of Iran, two such problems, namely the growing shortage of potable water and air pollution can be addressed by building a wind-p...
[ 9 ] - Implementation of Adaptive Neuro-Fuzzy Inference System (Anfis) for Performance Prediction of Fuel Cell Parameters
Fuel cells are potential candidates for storing energy in many applications; however, their implementation is limited due to poor efficiency and high initial and operating costs. The purpose of this research is to find the most influential fuel cell parameters by applying the adaptive neuro-fuzzy inference system (ANFIS). The ANFIS method is implemented to select highly influential parame...
[ 10 ] - Social sustainability assessment of conversion technologies: Municipal solid waste into bioenergy using Best Worst Method
The majority of sustainability assessments of the bio based industries are primarily focused on the environmental and economic aspects, while social impacts are rarely considered. While overlooking social dimension can have a serious harmful impact across supply chains. To address this issue, this study proposes a modified systemic approach for a social sustainability impact assessment of the te...
[ 11 ] - طراحی مدل پویایی سیستم برای بررسی رفتار شاخص بهره‌وری کل عوامل در ایران
افزایش یا کاهش بهره‌وری یک کشور یکی از عوامل مهم و مؤثر در تغییر اوضاع اقتصادی است. بنابراین، اندازه‌گیری بهره‌وری می‌تواند برای رصد کردن تغییرات در استانداردهای زندگی، در اثربخشی، یا در رقابت‌پذیری اقتصاد استفاده شود. بهترین شاخص نشان‌دهنده‌ی بهره‌وری جامع، بهره‌وری کل عوامل است. به همین دلیل در این پژوهش یک مدل پویایی سیستمی به شکلی طراحی شده است که شاخص‌های اثرگذار بر بهره‌وری کل عوامل بر ا...
