Energy-saving emission reduction (ESER) is the key project of our society, and electricity energy saving is actually one of the most important parts to contribute ESER. The effect of electricity energy saving will have a bearing on the success or failure of ESER. Because the implementation process of ESER policy is now with quite short time period allowed and there will be a large amount of uncertainties...
Patent value is defined and described from the following 3 aspects; market value, legal value and technological value. There have been done several researches regarding market value and legal value of patents, but no specific researches on technological value of patents, which can be evaluated from patented invention. The technological value is essential to give strong impacts on its market with long...
The problem of LMS selection can be ascribed to the wide section of decision making problems and can be solved using one of the ELECTRE method. The use of ELECTRE III method proved the effective selection of an e-leaning IT system. The method uses the quantitative and qualitative approach that expands it's range of use. The system selection is dependant from the decision maker preferences, which are...
Almost all of the learning paradigms used in machine learning, learning automata (LA), and learning theory, in general, use the philosophy of a student (learning mechanism) attempting to learn from a teacher. This paradigm has been generalized in a myriad of ways, including the scenario when there are multiple teachers or a hierarchy of mechanisms that collectively achieve the learning. In this paper,...
Based on the analysis of cold-chain process, it suggests using the theory of process control to analysis the critical control points in the cold-chain process, which influences the food safety. To identify the critical processes, this paper proposes a new and general decision making method for evaluating logistics systems using AHP and entropy weight method. Based on the integrated weight of criteria...
The location of logistics distribution center holds an very important position in the coal enterprise supply logistics system planning, the decision-makers need to consider various factors comprehensively. The traditional location method considers little about the interaction between the indexes during the location process. This paper introduce the principal component analysis (PCA)method in the location...
In the construction of large hydropower project, how to reduce supply risk and the integrated management cost of main materials supply is an important problem which the owner always faces with. Considering the supplier's supply capacity, supply risk and the management cost, an optimization mathematical model to minimize the sum of the risk loss of supply and management cost of the owner is established...
Under the pressure of global financial crisis, enterprises tend to enhance ability of Supply Chain Management (SCM) and their own advantages can be developed in the competition. A decision making model of multi-product multi-stage supply chain consisted of single manufacturer and single supplier is proposed in this article. The model is proved to be superior and efficient through application example...
In order to enhance the supporting capacity of military logistics distribution system under attack, according to its characteristic multiple covering, a model was designed for allocating limited protection resources to q of p existing facilities. The model was formulated in a bilevel programming, whose upper level maximized the extent of protected facilities covering customers when enemy destroyed...
In decision-making process, the index weight is identified as a core issue. The traditional correlation index weight determining method requires the experts to give the weights in the form of definite numbers based on experience. But in many cases , the experts in determining weights only give interval grey number weights which including of both certainty and uncertainty. This article, through a certain...
Situational simulations are dynamic, interactive, context-sensitive, adaptive environments. They further construction research by providing an interactive simulation platform that can be used to explore what-if construction scenarios and to estimate risks and contingencies. This paper extends current research to study the evolution of dynamic uncertainty in construction management projects using situational...
This paper aims to give out the order decision-making model of aviation materials storage management and to analyze the more economical way in view of supply chain management. The aviation materials are firstly divided into rotable parts and expendable parts, and then cycle inventory method, moving average method and the EOQ model are used to determine the inventory levels of AMs according to the...
The product collaborative design process had such characters: multidisciplinary, hierarchy, concurrent, phase, iteration, cooperativity, restriction and conflict- ineluctability. The present product design process modeling methods have their own characters, however, most of them suppose design to be a simple technical decision-making activity. They fail to describe the information completely, support...
Hybrid models of System Dynamics (SD) and Discrete Event Simulation (DES) in the construction industry aim to provide decision makers with more accurate analysis. However, there are certain issues that can limit the applicability of SD-DES hybrid models for real construction job situations. Meaningful Level of Change (MLC) is a concept that has been proposed to prevent the time advancing issue in...
In this paper we present the application of Simulation for Predictive Control (SimPC) as a decision making tool for improvement of non-automated distribution centers (DCs). SimPC is focused on determining the viability of a given truck- dock assignment schedule, including arrival times and dock assignments for inbound and outbound trucks. SimPC also serves to perform iterative procedures of system...
This paper outlines the application of a special Environmental Management Information System (EMIS) as combination of discrete event simulation with ecological material flow analysis for a selected production process. The software tool serves as decision aid for economic as well as ecological business problems. A combined view of the material flow as well as job-oriented view on an enterprise allows...
The supplier selection of maintenance and repair parts is very important for the maintenance of complicated equipments, as it is a multi-item, multi-person and multi-criteria decision problem. Among the recorded literature, the analytic hierarchy process (AHP) has been recognized as an appropriate approach to solve the above problem, which helps several decision-makers with different conflicting objectives...
There are, of course, a multiplicity of factors that will affect the time taken to construct a particular project. Using grey relational analysis, we can find the core factors influencing construction duration. The objective of this paper is to provide a tool based on grey relational analysis to aid clients and their consultants in estimating or benchmarking the construction duration. For the construction...
In this study, a multi-criterion decision-making methodology using the Fuzzy Comprehensive Evaluation (FCE) and Attribute Hierarchy Model (AHM) was provided to assist decision-makers in selecting the proper contractors for their projects. Firstly, the evaluating bids were discussed and indices of evaluating bids were proposed. Then, the indices of evaluating bids such as ?? Quality standard, Construction...
Over the past few years, firms have given more importance to the purchase-related decisions to gain competitive edge. Although great emphasis is given to the selection process of suppliers, commercial partnership may be terminated at a future date. This study, based on data from 66 automotive firms, examines factors affecting buyers' decision on the termination of the relationship with suppliers in...
