The first Winter Simulation Conference (WSC) papers on the use of simulation in semiconductor manufacturing appeared in the late 1980s and then appeared regularly throughout the 1990s. The first WSC track on semiconductor manufacturing was in 1996 and it was repeated in most WSCs over the next decade. The first Modeling and Analysis of Semiconductor Manufacturing (MASM) conference took place in 2000...
The method of non-overlapping batch means is the standard for constructing a confidence interval for the mean of a steady-state simulation output. In “Batch Size Effects in the Analysis of Simulation Output,” published in Operations Research in 1982, Schmeiser recast the problem of selecting a batch size by examining the marginal benefit of attaining the largest number of batches (smallest batch size)...
A kind of strategy decision-making risk analysis method is put forward based on uncertain event analysis, on the basis of potential uncertain events confronted in decision-makings. In this method, a model is constructed to generate the decision-making option space, with detailed generation ways based on the risks of uncertain events. By comparing the potential capacities of the enemy, self-army and...
The experts' opinions integration has always been an important part of group decision making. This paper analyses the consistency of general judgment matrix and proposes a model of group priority weight vector calculation. Through the analysis of this model, a genetic algorithms is designed, and values of some parameters are proposed. Since the Analytic Hierarchy Process in Generaliaed Judgemet(GJAHP)...
This thesis is based on a real estate project to study and resolve to meet the requirements of the project choice of advertising media. First, the media are available for selection analysis to determine the choice of media types, followed by the establishment of operations research model for media selection, and finally solve the model using slover and concluded, thus effectively solving the kind...
Consider the problem of selecting the best simulated system with high probability, from a finite and huge set of alternative systems. The best system might be the one that has the maximum or minimum performance measure. In this paper, we present a sequential method that uses the Ordinal Optimization procedure to select randomly a subset that overlaps with the set of the actual best m% systems with...
According to the need of industrial and agricultural production and living, we introduce “scatter sequence” of a regular triangle and build an optimization design model to maximize the minimum scatter numbers. Based on LINGO software, we obtain the solution of the minimum scatter numbers and their coordinates in some “scatter sequences” of the regular triangles with different numbers of points and...
To provide a broader education for Operational Research PhD students in the UK, the Engineering and Physical Sciences Research Council funds the National Taught Course Centre for Operational Research (NATCOR). This is an initiative led by six UK universities and includes a one-week, residential simulation module taught for the first time in July 2009. We describe the background to NATCOR, summarize...
Many companies are engaged in increasing their productivity and improving the quality of their products and operations. A means to achieve such improvements is to adopt Business Process Management practices. Techniques to analyze, evaluate and improve business processes are deemed Business Process Modeling. Currently, there are several methodologies and techniques for modeling to choose from. The...
This paper proposes a class of strict and high efficient Petri net algebras by combining the algebraic system theory with net transformation operations for model transformation of discrete event systems. The algebras include the fundamental operation systems of P/T net nodes and blocks as well as the advanced node-interfaced and block-interfaced net operation systems. Meanwhile, the algebraic properties...
It is difficult to use simple mathematics to quantize transit network optimization, because the transit network optimization is a multi-objective nonlinear programming problem, and the objective function is multiple and complex. The matter element analysis theory in extension field is introduced by some scholars. We can transform the multi-objective decision problem to a single-objective decision...
In this paper, totally based on the opinions in "Strategy Safari", we try to make analysis on modern strategy management theory in the way modern economy has introduced and practices in their researches, including new "perspective", "reference" and "analytical tools". Finally, we have established a new three-dimension (external controllable environment factors,...
According to the characteristics and the real situation of military equipment maintenance support, the paper analyzes the basic manner and contradiction of forming quality culture of equipment 6σ maintenance. And defines three major factors of forming quality culture as the attention and participation of commander, carrying out managing law, and building and improving the mechanism of rewards and...
A method of reverse logistics network design, which is based on operation research method(i.e. set covering location model and mix-integer linear programming) and DEDS simulation method, is proposed in the paper. And take some home appliance product company which is located in Sichuan, china for example, Its reverse logistics network for television remanufacturing in Sichuan is established and optimized...
Subway safety is a very important research area at home and abroad. According to a major subway accident occurred, the characteristic, operation pattern, system failure pattern of subway operation system is analyzed in this paper. The principle of system engineering is used, Comprehensive Safety Management System Framework was established for subway operational safety system. Comprehensive Safety...
Based on the Systematic analysis of the “Companies + farmers” Organization model, the System Dynamics (SD) Mathematical model is built to describe its development pattern. Using the Simulation Analysis technology of Vensim we simulate the development prospect and Restraints of the “Companies + farmers” Organization model and propose the corresponding managerial policies after analysis, achieving the...
Nowadays, the competition among enterprises has transformed into the competition within supply chains under the circumstance of rapidly developing E-commerce age, the reduction of logistics cost has already become the core element of the enterprises competition. This paper aims to establish SCOR-based enterprises ABM model, which includes logistics cost calculation, performance evaluating determination...
This paper sets up a DSS for faculty management and designs a model base for the system, which is based on the status of faculty management and the faculty information of college. Models of the system, such as teacher demand projections, teacher own quantity forecasting, student enrollment projections, and teacher classification structure prediction is designed by using of grey systems, operations...
How to study the operation risk is a puzzle in military organization cooperative operations among services. In this paper, risk existence conditions and characteristics were investigated to resolve illegibility problems in the operation risk. There were difference between risk decision making and full-uncertain decision making to be clarified. And then, three risk analysis approaches, the risk coefficient,...
The dynamic warfare command decision making with uncertainty, which considers the cross section with the fixed time, is investigated in this paper, The theoretical model is constructed, and corresponding solving method with the weight of time is proposed by means of the principle of identical discrepancy contrary (IDC) of set pair analysis (SPA). The method is used to analyze the transformation of...
