[ 1 ] - A Mixed Integer Programming Approach to Optimal Feeder Routing for Tree-Based Distribution System: A Case Study

A genetic algorithm is proposed to optimize a tree-structured power distribution network considering optimal cable sizing. For minimizing the total cost of the network, a mixed-integer programming model is presented determining the optimal sizes of cables with minimized location-allocation cost. For designing the distribution lines in a power network, the primary factors must be considered as m...

[ 2 ] - A New Mathematical Model To Optimize A Green Gas Network: A Case Study

Global warming created by large scale emissions of Greenhouse Gases (GHG) are a worldwide concern. Due to this, the issue of green gas network has required more attention in the last decades. Here, we address the GHG-based problem that arises in a gas network where gas flow is transferred from the Town Board Station (TBS) to consumers by pipeline systems. Given this environment, an optimization...

[ 3 ] - مدیریت زنجیرة تأمین پایدار و مدل تصمیم‌گیری راهبردی با توجه به هزینه‌های اجتماعی ناشی از آلودگی محیط‌زیست

مقالۀ پیش‌رو یک مدل تصمیم‌گیری راهبردی را با توجه به هزینه‌های اجتماعی آلودگی محیط‌زیست ناشی از عملیات‌ تولید و توزیع در شبکة زنجیره تأمین مورد نظر برای مدیریت زنجیره تأمین پایدار ارائه می‌دهد. مدیریت پایدار به کمترشدن ریسک‌های زیست‌محیطی و اجتماعی در کسب‌وکار اطلاق می‌شود. این مدل به‌منظور ارزیابی هزینۀ انتشار دی‌اکسیدکربن بر هزینه‌های عملیاتی تحت سناریوهای مختلف در یک شبکة زنجیرة تأمین تولید ...

[ 4 ] - Mathematical Model and Algorithm for sequencing operations in the machine building industry

In this paper, the problem of sequencing machines in the final assembly line with regard to the supply of parts has been investigated. For this reason, a basic integer linear programming model has been developed and based on this, the problem-solving algorithm is developed in accordance with the reaction-based approach based on the renewal of the sequence of operations. Also, due to the Np-hard...

[ 5 ] - How to Target Balanced Scorecard Indicators in a DEA-BSC Integrated Model

Performance measurement is always one of the most important tasks of managers, so knowledge management is measurement knowledge, and if we can measure something, we can no doubt control it, and therefore we cannot manage it. In this paper, according to the Malmquist productivity index, an index is used to determine the progress and regress of a unit. This index is defined by the boundary change...
