[ 2 ] - تخمین تلاش کلی نرم‌افزار و تلاش صرف‎شده در هر مرحلۀ تولید با استفاده از شبکۀ بیزی بهینه

دقت در تخمین تلاش لازم برای تولید نرم­افزار، موجب شده است که تخمین تلاش هنوز به‎عنوان موضوع چالش‎انگیزی مطرح باشد. علاوه‎بر تخمین تلاش کلی، تعیین تلاش صرف‎شده در هر مرحله از تولید نیز به‎دلیل برنامه­ریزی منابع اهمیت دارد؛ زیرا تخصیص نادرست منابع می­تواند به شکست پروژه منجر شود. در این مقاله، یک شبکۀ بیزی برای تخمین تلاش برپایۀ مؤلفه­های مؤثر و فرایند تولید ارائه شده است. در این مدل بین مراحل تو...

[ 3 ] - 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 ...

[ 4 ] - Location-Routing Problem with Fuzzy Time Windows and Traffic Time

The location-routing problem is a relatively new branch of logistics system. Its objective is to determine a suitable location for constructing distribution warehouses and proper transportation routing from warehouse to the customer. In this study, the location-routing problem is investigated with considering fuzzy servicing time window for each customer. Another important issue in this regard ...

[ 9 ] - Re-configuration of the Relief Network Considering Uncertain Demand and Link Failure in an Earthquake: A Multi-stage Stochastic Programming

Disasters inevitably trigger far-reaching consequences affecting all living things and the environment.  Therefore, top managers and decision-makers in disaster management seek comprehensive approaches to evaluate facilities and network preparedness in dealing with the response phase of predicted disaster scenarios in terms of number of casualties, costs, and unmet demands.  In this regard, pre...

[ 10 ] - Integration of Multi-period Vehicle Routing Problem and Economic Selection of Customers with the Objective of Optimizing Distribution, Sales and Discounts Planning

Making decisions about the economic selection of the customers plays a significant role in the sale and logistic management of the companies. Furthermore, another issue affecting the relationship between the suppliers and the customers is the proper and timely distribution of the products as well as the optimum mixing of the distribution routes to reduce transportation costs. In this paper, the...

[ 11 ] - Minimizing Makespan with Start Time Dependent Jobs in a Two Machine Flow Shop

[if gte mso 9]> The purpose of this paper is to consider the problem of scheduling a set of start time-dependent jobs in a two-machine flow shop, in which the actual processing times of jobs increase linearly according to their starting time. The objective of this problem is to minimize the makespan. The problem is known to be NP-hardness[ah1] ; therefore, there is no polynomial-time algorithm...

[ 12 ] - A Robust Two-stage Data Envelopment Analysis Model for Measuring Efficiency: Considering Iranian Electricity Power Production and Distribution Processes

This paper presents a new robust two-stage Data Envelopment Analysis (DEA) for efficiency evaluation of the electricity power production and distribution companies. DEA has been widely used for benchmarking the electricity companies. Traditional studies in DEA consider systems as a whole when measuring the efficiency, ignoring the operation of individual processes within a system. To tackle thi...

[ 13 ] - Deterministic and Metaheuristic Solutions for Closed-loop Supply Chains with Continuous Price Decrease

In a global economy, an efficient supply chain as a main core competency empowers enterprises to provide products or services at the right time in the right quantity, at a low cost. This paper is to plan a single product, multi-echelon, multi-period closed loop supply chain for high-tech products (which have continuous price decrease). Ultimately, considering components rated to procurement, pr...

[ 14 ] - A Novel Continuous KNN Prediction Algorithm to Improve Manufacturing Policies in a VMI Supply Chain

This paper examines and compares various manufacturing policies which manufacturer may adopt so as to improve the performance of a vendor managed inventory (VMI) partnership. The goal is to maximize the combined cumulative profit of supply chain while minimizing relevant inventory management costs. The supply chain is a two-level system with a single manufacturer and single retailer at each lev...
