优化问题是数学建模中的一类大问题,在历年全国大学生数学建模竞赛赛题中几乎离不开优化方法。多目标规划是大规模优化问题中最常见的一种,在现实的决策过程中,决策者面临的往往是一些具有多个目标的决策问题。多目标规划恰恰就是解决这类问题的理想方法,因而有着广泛的应用前景。本文从多目标规划的意义,发展现状,研究内容,技术难点,关键技术,研究方法,市场前景及社会效益等方面进行论述,使多目标规划模型在应用上更具有普遍性。  相似文献

1 引言目标规划是一类十分实用的重要模型,与一般多目标最优化模型不同,这类模型并不是考虑对各个目标进行极小化或极大化,而是希望在约束条件限制下,每一个目标都尽可能地接近于事先给定的各自对应的目标值。由于这类模型在处理问题时具有比较灵活、简便的特点,因而在工程技术和管理中应用非常广泛。本文研究逼近目标规划模型:  相似文献

Existing multicriteria analysis (MCA) methods are probably ineffective in selecting a supplier combination. Thus, an MCA-based fuzzy 0-1 programming method is introduced. The programming relates to a simple MCA matrix that is used to select a single supplier. By solving the programming, the most feasible combination of suppliers is selected. Importantly, this result differs from selecting suppliers one by one according to a single-selection order, which is used to rank sole suppliers in existing MCA methods. An example highlights such difference and illustrates the proposed method.  相似文献

Coordination between supply chain partners is critical to effective supply chain management. In this paper, we consider two cases of decision-making structure for a simple supply chain consisting of two players: the first case in which a supply chain partner dominates the decision-making process, and the other in which two players share the decision-making process equally. According to the literature, we know a priori that the balanced decision making forges a better (financial) outcome than the dominating case does. Therefore, our primary research objective is to analyze detailed dynamics of resource allocation and sources of the benefit of the balanced decision making. Our analysis indicates that the value of the balanced decision making arises from more effective resource utilization than the dominating case does: each of the cooperative partners knows how to optimize its resource utilization better than the other does.  相似文献

In this article, we first propose a closed-loop supply chain network design that integrates network design decisions in both forward and reverse supply chain networks into a unified structure as well as incorporates the tactical decisions with strategic ones (e.g., facility location and supplier selection) at each period. To do so, various conflicting objectives and constraints are simultaneously taken into account in the presence of some uncertain parameters, such as cost coefficients and customer demands. Then, we propose a novel interactive possibilistic approach based on the well-known STEP method to solve the multi-objective mixed-integer linear programming model. To validate the presented model and solution method, a numerical test is accomplished through the application of the proposed possibilistic-STEM algorithm. The computational results demonstrate suitability of the presented model and solution method.  相似文献

Researchers, practitioners and enterprise software providers are realising the potential of agent-based technology to automate supply chain procurement to achieve consistent, traceable decision making. As the complexity of supply chains grow, these systems will gain more attention. In this paper, we model and simulate a complex autonomous supply chain managed by computational agents that aim to minimise lead time and maximise revenue through evolutionary multi-objective optimisation. The agents are in a competitive environment where they take on the roles of both client and producer. In addition to optimising their production strategy, they also have the opportunity to dynamically fine-tune their decision parameters when it comes to selecting their own suppliers, using the Analytical Hierarchy Process. It is observed that computational agents are capable of functioning in such complex environments, effectively converging to policies in synergy with their market. Multi-objective, multi-role optimisation results in better overall supply chain performance than tests where agents have single-objectives and single-roles. Our study forms an exploratory step towards more realistic agent-based supply chains where analytical methods are unavailable.  相似文献

One of the critical activities for outsourcing success is outsourcing provider selection, which may be regarded as a type of fuzzy heterogeneous multiattribute decision making (MADM) problems with fuzzy truth degrees and incomplete weight information. The aim of this paper is to develop a new fuzzy linear programming method for solving such MADM problems. In this method, the decision maker’s preferences are given through pair-wise alternatives’ comparisons with fuzzy truth degrees, which are expressed with trapezoidal fuzzy numbers (TrFNs). Real numbers, intervals, and TrFNs are used to express heterogeneous decision information. Giving the fuzzy positive and negative ideal solutions, we define TrFN-type fuzzy consistency and inconsistency indices based on the concept of the relative closeness degrees. The attribute weights are estimated through constructing a new fuzzy linear programming model, which is solved by using the developed fuzzy linear programming method with TrFNs. The relative closeness degrees of alternatives can be calculated to generate their ranking order. An example of the IT outsourcing provider selection problem is analyzed to demonstrate the implementation process and applicability of the method proposed in this paper.  相似文献
