the construction of a mathematical model to imitate the behavior of a real-world situation or system in order to test the outcomes of alternative courses of action. Simulation was used in a military context by the Chinese as many as 5,000 years ago and has applications in the fields of science, research and development, economics, and business systems. The use of simulation has become more widespread since the development of computers in the 1950s, which facilitated the manipulation of large quantities of data and made it possible to model more complex systems. Simulation techniques are used in situations where real-life experimentation would be impossible, costly, or dangerous, and for training purposes.
Wiktionary Definition for: Simulation
Something which simulates a system or environment in order to predict actual behaviour.''
Ex: ''This exercise is a simulation of actual battle conditions.''
Ex: ''The most reliable simulation predicts that the hurricane will turn north.''
The process of simulating.
Ex: ''Despite extensive simulation in the design phase, the aircraft failed to behave as expected.''
Simulation is a tool for managing change. Practitioners in business process management know the critical importance of carefully leading organizations and people from old to new ways of doing business, and simulation is one way to accelerate change. This capability derives largely from the ability of simulation to bring clarity...
It has become a matter of survival that many companies improve their supply chain efficiency. This presents an opportunity for simulation. However, there are many challenges that must be overcome for simulation to be a contributor to play an effective role. In this paper, four contributors discuss the opportunities that...
The main contribution of this paper is twofold: it surveys different types of simulation for supply chain management; and it discusses several methodological issues. These different types of simulation are spreadsheet simulation, system dynamics, discrete-event simulation and business games. Which simulation type should be applied, depends on the type of...
Discrete event simulation has traditionally been defined by items or entities. This modeling paradigm has served the simulation industry well, but falls far short for many industries in which the parts / pieces mindset simply does not accurately portray their particular processes. For the last ten years Simulation Dynamics has...
Pharmaceutical manufacturers generally employ either organic synthesis or biotechnology. Each of these technologies has unique challenges, but batch process simulation and scheduling tools can facilitate process development in both. Batch process simulation is distinct from both traditional chemical process simulation and dynamic simulation and is uniquely suited to pharmaceutical processes....
Simulations study the interaction of random variables in a business process over time — how many customers might walk in the door at any moment, the return on an upcoming advertising campaign, the chance of your information system going down — and use the results to improve business policies. This...
Simulation might be an effective decision support tool in supply chain management. The review of supply chain simulation modeling methodologies revealed some issues one of which is the practicability of simulation in the supply chain environment. The supply chain environment is dynamic, information intensive, geographically dispersed, and heterogeneous. In order...
Simulation projects provide a useful way to tie together the expected learning outcomes in a simulation class. Designing a good project is a challenging task and simulation instructors are always on the lookout for interesting ideas. This paper provides simulation instructors with two interesting simulation applications, a supply chain project...
It has been seen that the mathematics behind simulation modeling is not new, but most planners do not have a background in statistics or simulation modeling. With this in mind, the article demystifies the process by taking apart a simple planning model that uses simulation techniques. They review the kind...
The development of web-enabled interactive training simulations is far from easy, especially when all models have to be developed from scratch for each training game. Actually, one would like to be able to reuse parts of existing, off-line simulation models in an interactive setting. The challenge is how to set-up...
From the executive summary: ‘Merger simulation is growing in importance as a tool to evaluate the unilateral competitive effects of mergers. The paper offers a relatively non-technical description of the principles of merger simulation. It introduces Proportionality-Calibrated Almost Ideal Demand System PCAIDS that can be implemented using market shares. The...
This paper explores the opportunities for simulation in Biotechnology over the next few years and provides structure for the panel discussion in Biotechnology and HealthCare track. It details the structure for Biotechnology industry, review status and opportunities for simulation and present gap analysis of opportunities and tools available. The purpose...
This paper reports on continuing work that concerns research into the development of a commercial off the shelf COTS distributed simulation environment federation using the Generic Runtime Infrastructure for Distributed Simulation to support the interoperation of simulation packages such as Arena, Extend, Simul8, Taylor, Witness, etc. The main aim of...
This paper presents a methodology that integrates fuzzy clustering and computer simulation and demonstrates its use in modeling earthmoving operations. A simulation system SimEarth was developed to model earthmoving operations utilizing object-oriented features and discrete event simulation. Fuzzy clustering is used to provide realistic estimates of haulers' travel time so...
Techniques based on discrete-event simulation have been widely used for network analysis and policy optimization in the domain of supply chain management. Previous researchers have developed and implemented architectures for simulation-based control for shop floor. A more detailed and high-fidelity simulation model is used for control purposes as opposed to...
Simulation software has reached a technological level that provides high flexibility and integration capabilities necessary for product design, development and manufacturing efficiency. Within the manufacturing industry, this simulation potential has not been fully recognized, although it is now becoming a matter of interest through the documented benefits it has provided....
The purpose of this paper is to discuss some of the issues that practitioners must be aware of in order to tap the potential of simulation in the health care arena. The panelists have extensive experience in health care and the use of simulation in that environment. They have provided...
The paper describes a number of applications of simulation methods to practical problems in finance and insurance. The first entails the simulation of a two-stage model of a property casualty insurance operation. The second application simulates the operation of an insurance regime for home equity conversion mortgages (also known as...
