[ 1 ] - مدلی استوار برای طراحی یک زنجیرۀ تأمین حلقه‌بستۀ پویا با قابلیت تنظیم ظرفیت
در این پژوهش، ابتدا با استفاده از یک برنامه‌ریزی خطی آمیخته، یک مدل جدید مکان‌یابی تسهیلات با ظرفیت محدود برای طراحی یک زنجیرة تأمین حلقه‌بسته در حالت چند‌محصولی و چند‌دوره‌ای ارائه میشود. سپس با استفاده از رویکرد بهینه‌سازی استوار مدل پیشنهادی در حالت غیرقطعی گسترش مییابد. براساس نتایج، با استفاده از مدل پیشنهادی می‌توان ظرفیت تسهیلات در یک شبکة لجستیکی حلقه‌بسته را تنظیم کرد. به‌علاوه، نتای...
[ 2 ] - انتخاب سبد پروژه‌های احداث با رویکرد توسعۀ پایدار تحت شرایط عدم قطعیت فازی بازه‌ای نوع دوم
انتخاب صحیح پروژه‌ها اولین گام سازمان‌های پروژه‌محور در مدیریت راهبردی و هدفمند سبد پروژه‌هاست. با توجه به وابستگی رشد اقتصادی به مسائل زیست‌محیطی و اجتماعی، بحث توسعة پایدار قسمتی از راهبردهای اصلی سازمان‌های پیشرو شده است. همچنین، شرایط بازار، تغییرات سریع جهانی در ابعاد مختلف و سایر مسائل مرتبط موجب شده است عدم قطعیت و ناآگاهی در این مسائل بیش از پیش افزایش یابد. درنتیجه، در این پژوهش روشی ...
[ 3 ] - An Assessment Method for Project Cash Flow under Interval-Valued Fuzzy Environment
Effective project management requires reliable knowledge of cash required in different stages of project life cycle. Getting this knowledge is highly dependent on sophisticated consideration of project environment. Nature of projects and their environments are associated with uncertain conditions. In this paper, a new project cash flow assessment method based on project scheduling is proposed t...
[ 4 ] - A Fuzzy Decision-Making Methodology for Risk Response Planning in Large-Scale Projects
Risk response planning is one of the main phases in the project risk management and has major impacts on the success of a large-scale project. Since projects are unique, and risks are dynamic through the life of the projects, it is necessary to formulate responses of the important risks. The conventional approaches tend to be less effective in dealing with the impreciseness of risk response p...
[ 5 ] - Self-Starting Control Chart and Post Signal Diagnostics for Monitoring Project Earned Value Management Indices
Earned value management (EVM) is a well-known approach in a project control system which uses some indices to track schedule and cost performance of a project. In this paper, a new statistical framework based on self-starting monitoring and change point estimation is proposed to monitor correlated EVM indices which are usually auto-correlated over time and non-normally distributed. Also, a new ...
[ 6 ] - یک مدل ریاضی برای انتخاب سبد پروژه با درنظرگرفتن وابستگی متقابل میان پروژه‌ها، قابلیت شکست پروژه‌ها، سرمایه‌گذاری مجدد و روش‌های گوناگون تأمین منابع
مدیریت سبد (پورتفولیو) پروژه، فرایند تکرارشدنی ارزیابی، انتخاب و اجرای پروژه‌هاست و قلب آن انتخاب سبد پروژه است. طی این امر، سازمان پروژه‌هایی که بیشترین هم‌راستایی را با اهداف راهبردی دارند شناسایی و اولویت‌بندی می‌کند و با توجه به محدودیت‌ها و ملاحظات واقعی در زمان‌بندی پروژه‌ها و تخصیص منابع، با زمان‌بندی و تخصیص منابع صحیح و هدفمند هرچه بیشتر به اهداف خود می‌رسد. در این پژوهش، یک مدل ریاضی ...
[ 7 ] - Solving Critical Path Problem in Project Network by a New Enhanced Multi-objective Optimization of Simple Ratio Analysis Approach with Interval Type-2 Fuzzy Sets
Decision making is an important issue in business and project management that assists finding the optimal alternative from a number of feasible alternatives. Decision making requires adequate consideration of uncertainty in projects. In this paper, in order to address uncertainty of project environments, interval type-2 fuzzy sets (IT2FSs) are used. In other words, the rating of each alternativ...
[ 8 ] - Solving New Product Selection Problem by a New Hierarchical Group Decision-making Approach with Hesitant Fuzzy Setting
Selecting the most suitable alternative under uncertainty is considered as a critical decision-making problem that affects the success of organizations. In the selection process, there are a number of assessment criteria, considered by a group of decision makers, which often could be established in a multi-level hierarchy structure. The aim of this paper is to introduce a new hierarchical multi...
[ 9 ] - Evaluating Construction Projects by a New Group Decision-Making Model Based on Intuitionistic Fuzzy Logic Concepts
Select an appropriate project is a main key for contractors to increase their profits. In practice, in this area the uncertainty and imprecise of the involved parameters is so high. Therefore, considering fuzzy sets theory to deal with uncertainly is more appreciate. The aim of this paper is present a multi-criteria group decision-making model under an intuitionistic fuzzy set environment. Henc...
[ 10 ] - A New Balancing and Ranking Method based on Hesitant Fuzzy Sets for Solving Decision-making Problems under Uncertainty
The purpose of this paper is to extend a new balancing and ranking method to handle uncertainty for a multiple attribute analysis under a hesitant fuzzy environment. The presented hesitant fuzzy balancing and ranking (HF-BR) method does not require attributes’ weights through the process of multiple attribute decision making (MADM) under hesitant conditions. For the rating of possible alternati...
[ 11 ] - A New Compromise Decision-making Model based on TOPSIS and VIKOR for Solving Multi-objective Large-scale Programming Problems with a Block Angular Structure under Uncertainty
This paper proposes a compromise model, based on a new method, to solve the multi-objective large-scale linear programming (MOLSLP) problems with block angular structure involving fuzzy parameters. The problem involves fuzzy parameters in the objective functions and constraints. In this compromise programming method, two concepts are considered simultaneously. First of them is that the optimal ...
[ 12 ] - Optimal Design of the Cross-docking in Distribution Networks: Heuristic Solution Approach
A design problem of cross-docking distribution networks is addressed as a new research area in logistics management. This paper presents a new mathematical model for the location of cross-docking facilities and vehicle routing scheduling problems in distribution networks. For this purpose, a two-phase mixed-integer programming (MIP) is formulated. Then, a new heuristic-based simulated annealing...
[ 13 ] - A Multi-Criteria Decision-Making Approach with Interval Numbers for Evaluating Project Risk Responses
The risk response development is one of the main phases in the project risk management that has major impacts on a large-scale project’s success. Since projects are unique, and risks are dynamic through the life of the projects, it is necessary to formulate responses of the important risks. Conventional approaches tend to be less effective in dealing with the imprecise of the risk response deve...
[ 14 ] - An integrated AHP-VIKOR methodology for plant location selection
Plant location selection invariably has a significant impact on the performance of many companies or manufacturing systems. In this paper, a novel methodology is structured to solve this problem. The two decision making methods, namely AHP and VIKOR, are integrated in order to make the best use of information available, either implicitly or explicitly. In addition, the Delphi method is utilized...
[ 15 ] - Hierarchical Group Compromise Ranking Methodology Based on Euclidean–Hausdorff Distance Measure Under Uncertainty: An Application to Facility Location Selection Problem
Proposing a hierarchical group compromise method can be regarded as a one of major multi-attributes decision-making tool that can be introduced to rank the possible alternatives among conflict criteria. Decision makers’ (DMs’) judgments are considered as imprecise or fuzzy in complex and hesitant situations. In the group decision making, an aggregation of DMs’ judgments and fuzzy group compromi...
