به دلیل عدم قطعیت‌های شناختی، تصادفی و محدودیت‌های انعطاف پذیر، در این مطالعه مدل جدیدی از برنامه‌ریزی محدودیت شانس انعطاف‌پذیر، امکانی، استوار مختلط بر مبنای تئوری اعتبار برای طراحی شبکه زنجیره تامین حلقه بسته توسعه داده شد. نگرش‌های متفاوت تصمیم‌گیرندگان با اندازه‌گیری انعطاف‌پذیرتر پارامترهای خوش‌بینانه بدبینانه قالب معیار پاسخ حداقل سطح رضایت انعطاف‌پذیر حل بهینه گردید. پیشنهادی، قادر کاهش ...

Biodiesel production sustainability relates to decision making on blending involving economic and environmental criteria. Several feedstocks candidate in European countries biodiesel industry, namely different vegetable origin oils. The present research aims at assessing the impact of technological constraints allocated to the decision objectives taking into account ...

A multi-product newsboy problem with uncertain demand and uncertain storage space is investigated under a warehousing chance constraint. It is assumed that indeterminacy may appear in demand and storage space due to rough estimation of their distributions by decision-maker. Uncertainty theory provides a new tool to deal with the human uncertainty. We develop an uncertain expected value programm...

There are two types of critical values for birandom variable: the optimistic and pessimistic values. In this paper, some theoretical aspects of optimistic and pessimistic values of birandom variable are investigated. Based on the results, some properties of birandom chance-constrained programming models can be further discussed.

The computation problem is discussed for the stochastic chance-constrained linear programming, and a novel direct algorithm, that is, simplex algorithm based on stochastic simulation, is proposed. The considered programming problem in this paper is linear programming with chance constraints and random coefficients, and therefore the stochastic simulation is an important implement of the propose...

A chance-constraint multi-objective model under uncertainty in the availability of subassemblies is proposed for scheduling in ATO systems. The on-time delivery of customer orders as well as reducing the company's cost is crucial; therefore, a three-objective model is proposed including the minimization of1) overtime, idletime, change-over, and setup costs, 2) total dispersion of items’ deliver...

This paper presents a chance constrained information gap decision model for multi-period microgrid expansion planning (MMEP) considering two categories of uncertainties, namely random and non-random uncertainties. The main task of MMEP is to determine the optimal sizing, type selection, and installation time of distributed energy resources (DER) in microgrid. In the proposed formulation, inform...

Based on the fuzzy random chance-constrained programming(FRC) theory, the paper presents a method to calculate active-power-output of large-scale wind power farms connected to power grid. The calculation of active-power-output can be turned into a FRC programming problem which constrained conditions. This paper put forward a mathematical model of calculate active power in wind power integrated ...
