In this tutorial three experienced instructors describe how they teach an advanced simulation topic: Poisson processes (Henderson), variance reduction (Jacobson), and verification and validation (Robinson). 1 HENDERSON: POISSON PROCESSES

This paper provides an examination of different modeling situations implemented in Extend, Arena, and Silk and demonstrates how the implementation of the software impact the results and whether these behaviors can be modified. The modeler being more informed of the methods implemented can work within the software to more accurately produce the desired outcome. The methods may not be obvious and...

We show how theorem proving and methods for handling real algebraic constraints can be combined for hybrid system verification. In particular, we highlight the interaction of deductive and algebraic reasoning that is used for handling the joint discrete and continuous behaviour of hybrid systems. We illustrate proof tasks that occur when verifying scenarios with cooperative traffic agents. From...

This paper examines the implementability of social choice functions when only partial verification of private information is possible. Green and Laffont (1986) used this framework to derive a necessary and sufficient condition for the revelation principle to continue to hold with partial verification. We provide economically interesting characterizations of this condition, which suggest that it...

This paper presents a methodology for the verification of reactive multi-agent systems (RMAS). High level of confidence about a safe operation is a mandatory in many reactive applications. Model-checking appear as an adequate tool for the verification of safety properties. However, model-checking can be confronted with the problem of intractable state space sizes. To avoid this kind of limitati...

Grid workflow systems aim to support large-scale complex e-science and e-business processes. Due to the complexity of these kinds of processes, to control the execution of them in terms of time in the grid workflow execution environment, multiple fixed-date temporal constraints often need to be set simultaneously. Hence the dependency problem between them must be considered and emphasised, whic...

This paper introduces a new notion called Verification & Validation (V&V) Lifecycle Method-ologies, examining what V&V is, and expanding its scope to the entire software lifecycle (much beyond traditional methods of software testing). V&V Lifecycle Methodologies are streamlined and efficient, yet highly holistic and concisely measured step-by-step threaded and sequenced approaches to predictive...

This paper presents the integrated use of the Spin Model Checker in conjunction with Structured Methods (SA/RT). The graphical model is translated into a Promela program in which we prove assertions about the desired behaviour of the system. We also provide support for modular verification, by separately verifying different components of the model and deducing the desired global properties from...

This paper at first introduces an examination in Japan to standardize traffic simulation models. The basic idea of the standardization here is to estimate abilities of existing models how to reproduce traffic conditions through verification and validation. Verification implies qualifying tests using virtual data sets in order to make a connection between the simulation model and the traffic-eng...

The field of memetics is characterised and two types of memetic model analysed: the a priori model and the ‘black-box’ model. These are used to motivate a picture of scientific modelling, where by chains of models are built from abstract models at the ‘top’ down to data models derived from measurement. These models are linked to each other by validation (where the structure of a model comes fro...
