Process Modelling Support For The Conceptual Modelling Phase Of A Simulation Project, Cathal Heavey, John Ryan
Process Modelling Support For The Conceptual Modelling Phase Of A Simulation Project, Cathal Heavey, John Ryan
Conference papers
While many developments have taken place around supporting the model coding task of simulation, there are few tools available to assist in the conceptual modelling phase. Several authors have reported the advantages of using process modelling tools in the early phases of a simulation project.
This paper provides an overview of process modelling tools in relation to their support for simulation, categorizing the tools into formal method and descriptive methods. A conclusion from this review is that none of the tools available adequately support the requirements gathering phase of simulation. This is not surprising as none of the process modelling …
Hazardous Materials Transportation: A Meta-Analysis Of State Level Policy And Regulations, David J. Pastika
Hazardous Materials Transportation: A Meta-Analysis Of State Level Policy And Regulations, David J. Pastika
Theses and Dissertations
Every day, over 800,000 hazmat transactions take place across the United States. This segment of transportation is expected to grow at a modest two percent a year for the foreseeable future but differences of regulations between the state and Federal level have been a growing concern for both the government and members of the hazmat industry. A patchwork of often inconsistent permits, registration requirements, and hazmat organizational structures at the state level often create barriers to the efficient means of commerce for hazmat carriers and shippers. This thesis explores the history of hazardous regulations since de-regulation of the trucking industry …
A Template-Based Data Specification Framework For Modeling Physical Security Systems, Ashu Guru, Paul Savory
A Template-Based Data Specification Framework For Modeling Physical Security Systems, Ashu Guru, Paul Savory
Department of Industrial and Management Systems Engineering: Faculty Publications
Simulation studies often fail to provide any useful results due to its success being highly dependent on the skills of the analyst to understand a system and then correctly identify all the required data parameters and dependent variables. This paper describes a template-based framework to help identify and specify the components and data parameters for developing models of physical security systems. The layered framework consists of fifteen templates built on top of fourteen data primitives representing 119 data parameters. The modeling framework has been programmed as an internet-based web application and is simulation language independent. The usefulness of the framework …

Class Exercise For Assessing Abilities And Providing A Structure For A Course, Paul Savory
Class Exercise For Assessing Abilities And Providing A Structure For A Course, Paul Savory
Industrial and Management Systems Engineering: Instructional Materials
I developed this class exercise to assess students abilities and to highlight the range of questions/issues that they will learn in my IMSE 440/840 (Discrete Event Computer Simulation) course. I draw a picture of the case scenario for students and explain the system’s operation to them. I then ask that they complete the questions regarding the system and/or how they would analyze it. Following class, I develop a summary of the range of student answers. At the next class session, I share the range of answers and share what my answers would be and how these questions/topics relate to what …
Requirements Gathering For Simulation, John Ryan, Cathal Heavey
Requirements Gathering For Simulation, John Ryan, Cathal Heavey
Conference papers
This paper discusses the current shortfalls in support for the pre-coding phases of a discrete event simulation project. The paper then presents a process modelling technique, Simulation Activity Diagrams (SADs), developed to specifically support the initial requirements gathering phases of a simulation project. The paper concludes with an outline of proposed future developments to the modelling technique.

This paper discusses shortfalls in relation to the requirements gathering phases of simulation. While many developments have taken place around supporting the model coding task of simulation, there are few tools available to assist in the requirements gathering phase. This is surprising as it has been reported by several researchers that the requirements phase can absorb twice as much resources as the coding phase. There are numerous process modeling tools available (over 100) that can and have been used to support the requirements phase of simulation. This paper provides a selective review of some of the most important in relation …
